Unit 203 – Video Software
Aim of this unit
This unit is about the ability to use video software applications designed to record and edit video sequences.
An intermediate user can select and use a wide range of intermediate video software tools and techniques to record and edit video sequences that are at times non-routine or unfamiliar.
Video software tools and techniques will be defined as ‘intermediate’ because:
- the software tools and functions involved will at times be non-routine or unfamiliar;
- the choice and use of input, manipulation and output techniques will need to take account of a number of factors or elements and at times be multi-step;
- the user will take some responsibility for inputting, manipulating and outputting the information.
Examples of context: Recording pre-planned video footage, downloading the footage to a computer, then editing to create a short sequence, including adding some background music or adding them to a file of another application – word processing, spreadsheet, presentation, etc
1. Use video hardware and software to capture sequences
There are many ways to capture sequences of video. Hardware and software options abound, each with its own strengths and weaknesses. In this article, we will explore two popular methods of capturing video: hardware and software.
Hardware-based video capture is the use of a device, such as a digital camera or camcorder, to record video footage. This method is popular among amateur and professional videographers alike. The main advantage of hardware-based capture is that it requires no additional software; simply connect your camera to your computer and start recording.
However, hardware-based capture can be more expensive than software-based capture, and it is often difficult to edit footage captured with a hardware device.
Software-based video capture is the use of a program, such as a screen recorder or webcam recorder, to record video footage. This method is popular among online content creators and gamers. The main advantage of software-based capture is that it is typically more affordable than hardware-based capture.
Additionally, many software-based capture programs offer robust editing tools, making it easy to edit your footage after recording.
However, one downside of software-based capture is that it can be more difficult to achieve high-quality recordings. Additionally, some software-based capture programs can be resource-intensive, meaning they may slow down your computer while recording.
No matter which method you choose, video capture can be a great way to preserve memories, document events, or create engaging content for your audience.
1.1 Identify the combination of an input device and audio software to use to capture information, to avoid any compatibility issues
There are a variety of input devices and audio software combinations that can be used to capture information. The most important factor to consider when choosing a combination is whether or not the devices will be compatible with each other.
Some combinations may work well together, while others may have compatibility issues that can cause problems with the recording process. It is important to research different combinations before making a final decision in order to avoid any potential problems.
Some of the most popular input devices include:
- Digital cameras
- Mobile phones
Each of these devices has its own strengths and weaknesses, so it is important to choose one that will best suit the needs of the project. For example, a microphone may be better for capturing audio information, while a digital camera may be better for capturing video information.
There are also a variety of audio software programs that can be used to capture information. Some of the most popular programs include:
- Pro Tools
Each of these programs has its own strengths and weaknesses, so it is important to choose one that will best suit the needs of the project.
For example, Audacity may be better for capturing high-quality audio recordings, while Pro Tools may be better for capturing video recordings.
When selecting an input device and audio software combination, it is important to consider the specific needs of the project. By taking the time to research different combinations, it is possible to avoid any potential compatibility issues. With a little bit of planning, it is possible to find the perfect combination for any information-capturing project.
1.2 Select and use an appropriate combination of an input device and audio software to record sequences

1.3 Describe the impact file size and file format will have on saving sequences
Proprietary formats supported by the software include QuickTime, RealPlayer, and iTunes to name a few.
Most people are unaware that the software they use to play music and videos also supports a wide range of proprietary file formats. Proprietary file formats are those that are developed by a company or organization and not made available to the general public.
This can be done for a variety of reasons, such as to protect the company’s intellectual property or to create an additional revenue stream. While most proprietary file formats are used for audio and video files, there are also a number of proprietary document formats in use today.
The most common proprietary file format is QuickTime, which is used by Apple’s iTunes software. QuickTime files can only be played on computers running Apple’s QuickTime Player software or on devices that support the QuickTime format.
Other popular proprietary file formats include RealPlayer, Windows Media Player, and Adobe Flash. Each of these formats has its own advantages and disadvantages, and it is up to the individual user to decide which format is best for their needs.
File size is the amount of data that a particular file contains. This is usually measured in kilobytes, megabytes, or gigabytes. The larger the file size, the more storage space it will take up on your computer.
File format refers to the way in which information is encoded within a digital file. There are many different types of file formats, each with its own advantages and disadvantages. Some formats are better suited for storing video files, while others are better for storing audio files.
When saving sequences, you need to choose a file format that will produce the smallest possible file size while still maintaining good quality. You also need to make sure that your software can read that particular format.
Some of the most popular audio formats include:
There are a variety of audio formats that are popular among consumers. Some of these formats include MP3s, WMA WAV, XMK and AIFF. Each format has its own set of benefits and drawbacks that influence consumer choice.
MP3s are a very popular audio format because they offer good sound quality and are highly compatible with many different types of devices. However, MP3s are also relatively large files, which can take up a lot of space on your hard drive or other storage devices.
WMA is another popular audio format that offers excellent sound quality. However, WMA files are not as widely compatible with different types of devices as MP3 files.
WAV is an audio format that is known for its high-quality sound. However, WAV files are very large, which can make them difficult to store and transport.
XMK is a newer audio format that offers excellent sound quality and is very efficient in terms of file size. However, XMK files are not as widely compatible with different types of devices as MP3 or WAV files.
AIFF is an audio format that is known for its high-quality sound. However, AIFF files are very large, which can make them difficult to store and transport.
Some of the most popular video formats include:
There are a variety of audio formats that are popular among consumers. Some of these formats include MP4s, AVI, OGG, MOV, FLV and F4V and SWF. Each format has its own set of benefits and drawbacks that influence consumer choice.
MP4s, also known as MPEG-4s, are a more recent audio format that offers even higher levels of compression than MP3s. This means that they take up even less space on a device, making them ideal for downloading music. They also offer slightly better sound quality than MP3s. However, like MP3s, they cannot be easily edited or manipulated.
AVI is another popular format that is compatible with most media players and devices. However, it offers slightly lower-quality audio and video than MP4s. It also has a larger file size than MP4s, which can make it slower to load on some computers.
OGG files offer high-quality audio and video, but they are not as widely compatible with media players and devices as MP4s and AVI files. They also have a larger file size than MP4s and AVI files, which can make them slower to load on some computers.
MOV files are a popular format for videos that are edited or contain special effects. They offer high-quality audio and video, but they are not as widely compatible with media players and devices as MP4s, AVI files, and OGG files. They also have a larger file size than MP4s, AVI files, and OGG files, which can make them slower to load on some computers.
FLV, F4V and SWF – these files are a popular format for videos that are streamed online, such as on YouTube. They offer good quality audio and video, but they are not as widely compatible with media players and devices as MP4s, AVI files, OGG files, and MOV files. They also have a larger file size than MP4s, AVI files, OGG files, and MOV files, which can make them slower to load on some computers.
1.4 Identify when to use different types of information coding and compression
The ability to identify when to use different types of information coding and compression within video software can be extremely helpful in order to create high-quality videos. By understanding the different types of coding and compression, you can ensure that your videos are properly processed and look their best.
There are two main types of video coding: intra-frame and inter-frame. Intra-frame coding encodes each frame of video independently, while inter-frame coding encodes frames in relation to other frames. In general, intra-frame coding results in higher-quality videos, but it can also be much more computationally expensive. Inter-frame coding is typically used when storage space or bandwidth is limited, or when real-time encoding is required.
There are also many different types of codec video compression, which can be applied either losslessly or lossily. Lossless compression means that no information is lost during the compression process, while lossy compression involves some data loss. Lossy compression can provide significantly smaller file sizes, but at the expense of some quality.
When choosing which type of coding and compression to use, it is important to consider the desired quality of the video, the available storage space or bandwidth, and the required encoding speed. In general, higher-quality videos will require more storage space or higher bandwidth and may take longer to encode.
Conversely, lower-quality videos will take up less space and can be encoded more quickly. Ultimately, the decision of which coding and compression to use will come down to a trade-off between quality and efficiency.
1.5 Store and retrieve sequences using appropriate file formats and compression, in line with local guidelines and conventions where available
As technology advances, the way we store and retrieve data changes as well. With new compression techniques and file formats, it is now easier than ever to keep track of your files and folders. By following local guidelines and conventions, you can ensure that your data is organized and easy to find.
When it comes to storing and retrieving files, most people know the basics: create, name, open, save, save as, print, close, find, and share. But there are a few other things you should know in order to make the process smoother. For example:
- File size is important to consider when saving a document. The larger the file size, the longer it will take to upload or download.
- Version control can be helpful in identifying similar file names. When two files have the same name but different extensions (e.g. .docx and .doc), version control will tell you which is which.
- Importing data can be a great way to quickly fill out a spreadsheet or table. All you need is a file with the correct format and you’re good to go!
- Exporting data is just as easy – simply choose the format you want your data exported in and hit export!
- Folders are an important part of organizing your files. They help keep everything neat and tidy and make it easier to find what you’re looking for. So when you’re creating or naming a folder, take a moment to think about what would make it easiest for you to find later on.
2. Use video software tools and techniques to combine and edit sequences
Video editing software provides a wide range of tools and techniques for combining and editing sequences. With the right tools, you can create professional-looking videos that capture your message and communicate it to your audience.
The first step in any video editing project is to import your footage into the software. This is usually done by connecting your camera to your computer and transferring the files over. Once your footage is in the software, you can begin adding it to your project.
Most video editing software uses a timeline-based interface. This means that your project is represented as a line, with each piece of footage appearing as a separate clip. You can add these clips to the timeline and arrange them in any order you like.
Most software also provides a range of tools for editing your footage. These include trimming, adding transitions, and applying effects. With the right tools, you can create a professional-looking video that communicates your message clearly.
Some of the most popular video editing software include:
- Adobe Premiere Pro
- DaVinci Resolve
- Sony Vegas Pro
- Final Cut Pro X
- Windows Movie Maker
2.1 Identify the footage to add, keep and remove
In order to create a successful video, it is important to first identify the footage that will be used and cut the unnecessary footage. This will ensure that the video flows smoothly and does not contain any jarring cuts.
When cutting footage, it is important to keep the following in mind:
- The video should flow smoothly and logically
- There should be a clear beginning, middle, and end
- All footage should contribute to the overall message of the video
If any footage does not meet these criteria, it should be removed from the final cut.
After the footage has been cut, it is time to add any additional video or audio elements that will enhance the overall message of the video. These could include things like music, voice-over, or sound effects.
Once all of the elements have been added, it is time to export the final video. This will ensure that the video is in the correct format and resolution for distribution.
Sequences can be short (eg less than 2 mins), black and white, medium length (eg 10 mins to 30 mins), colour and long videos (eg 30 mins plus).
2.2 Select and use appropriate audio software tools to mark up and edit sequences
Using audio software tools to mark up and edit sequences can be a great way to improve the quality of your work. By taking the time to carefully select and use the appropriate tools, you can make sure that your sequences are accurately edited and marked up. This will help to ensure that your work is of the highest quality possible.
There are a variety of different audio software tools available on the market. Some of these tools are designed for specific purposes, while others are more general in nature. When selecting audio software tools to use for your work, it is important to consider the specific needs of your project.
For example, if you are working on a project that requires a lot of precision editing, you may want to consider using a tool that is specifically designed for this purpose.
On the other hand, if you are working on a project that is less time-sensitive and does not require as much precision, you may be able to get away with using a more general audio software tool.
Some of the most popular audio software tools include:
- Adobe Audition
Once you have selected the audio software tools that you will use for your project, it is important to learn how to use them properly. This means taking the time to read the documentation and tutorials that are available for each tool.
It may also be helpful to consult with someone who is more experienced in using audio software tools. By taking the time to learn how to use the tools properly, you can ensure that your project will benefit from their use.
2.3 Organise and combine information for sequences in line with any copyright constraints, including across different software
It’s no secret that technology has had a profound impact on the way we create and share content. Audio and video are now more accessible than ever before, and there are countless software options available for users of all levels of experience.
However, organising and combining information for audio and video sequences can be tricky, especially when copyright constraints are taken into account. In this age of digital media, it’s more important than ever to stay informed about the latest tools and technologies in order to create content that is both high quality and legally compliant.
Organising and combining information for audio and video sequences (eg dub or overlay soundtrack onto film sequence) can be a time-consuming and confusing process, especially when copyright constraints are taken into account. In order to ensure that your content is of the highest quality and legal compliance, it is important to stay up-to-date with the latest tools and technologies. Below is a list of resources that will help you to create legally compliant audio and video content:
Content Sharing Platforms:

- Intellectual Property Office: https://www.gov.uk/government/organisations/intellectual-property-office
- U.S. Copyright Office: https://www.copyright.gov/
- Creative Commons: https://creativecommons.org/
By staying up-to-date with the latest tools and technologies, you can create audio and video content that is both high quality and legally compliant. With the right resources, you can ensure that your content will reach a wide audience while also protecting your rights as a creator.
2.4 Describe how copyright constraints affect the use of your own and others’ information
Most people are unaware of the copyright constraints that affect their use of information.
When it comes to using other people’s information, most people think that as long as they give credit where it is due, they are in the clear. However, this is not always the case. There are a number of ways in which copyright law can be violated without even realizing it.
For example, using another person’s work in a presentation or publication without getting permission first can be considered a violation.
Additionally, copying text from one source and pasting it into your own work without giving credit to the original author can also lead to legal trouble. It is important to be aware of these constraints and to take steps to avoid violating copyright law whenever possible.
When it comes to using your own information, copyright law can also come into play. If you have created something original, such as a piece of writing or a piece of artwork, you automatically have the copyright to that work.
This means that no one else can use it without your permission. Copyright law can be complex, but understanding the basics can help you to avoid accidentally violating it.
3. Play and present video sequences
Video content creators use a variety of methods to play and present their video sequences in order to grow their audience and build their brand. One common method is to post short snippets of the video on social media platforms like Twitter or Instagram.
This allows viewers to get a taste of the video content and encourages them to watch the full sequence. Additionally, many creators will create themed videos around specific holidays or events, which can attract new viewers who are interested in that topic.
Finally, creators often use creative editing techniques to make their videos more engaging and visually appealing. By using these various methods, content creators can build a larger audience and strengthen their brand identity.
3.1 Describe the features and constraints of playback software and display devices
Display devices, such as projectors, TVs, tablets and monitors, are used to show images and videos. The quality of the image depends on various factors such as the resolution of the display device and the speed of the transmission.
The resolution is the number of pixels in an image. A higher resolution means more detail in the image. The transmission speed is how quickly data can be sent from one place to another. A faster transmission speed means that more data can be sent in a shorter amount of time, which results in a higher-quality image.
There are various types of playback software, each with its own features and constraints. Some playback software is designed for specific file formats, while others can support multiple file formats. Some playback software is designed to run on certain operating systems, while others can be used on any operating system.
The features of playback software include the ability to play back audio and video files, support for multiple file formats, the ability to control playback speed, and the ability to skip ahead or backwards in a file. The constraints of playback software include limited support for certain file formats, the need for a compatible operating system, and the need for certain hardware to be present in order to use the software.
In order to choose the best playback software for your needs, you should consider the types of files you want to playback, the operating system you are using, and the hardware you have available. You should also consider the quality of the image and the speed of the transmission.
3.2 Select and use an appropriate combination of audio playback software and display device to suit the file format
There are a variety of audio playback software and devices available on the market to suit different file formats. PC users can use Windows Media Player, iTunes or Winamp to play back mp3s, while those with a laptop might want to consider using VLC media player.
If you have a video camera, there are many software options that will allow you to view your footage, such as Adobe Premiere Elements or Sony Vegas Movie Studio. If you have an iPhone or other handheld device that plays videos, there are a number of apps available for download that will cater to your needs.
When selecting audio playback software, it is important to consider the file format of the files you wish to play. For example, mp3s are a very popular file format, but they are not compatible with all devices. If you have an iPod, you will need to use iTunes to play your mp3s.
Similarly, if you have a video camera, you will need to find software that can read the file format of your footage. Once you have selected the appropriate software for your needs, you can then select a compatible display device.
PCs usually come with speakers built in, but if you want to improve the audio quality, you might want to consider investing in a set of external speakers. These can be connected to your PC via a USB port or an audio jack. If you have a laptop, you might also want to consider using headphones to listen to your audio files, as this will allow you to enjoy the sound without disturbing those around you.
When it comes to choosing a display device, there are a few different options available. If you just want to listen to your audio files, you can use your PC or laptop’s built-in speakers. However, if you want to watch videos or view photos, you will need to connect an external monitor or TV.
This can be done using a VGA cable, DVI cable, HDMI cable, S-Video cable or mirror casting via wifi. If you have a video camera, you will also need to connect it to your TV in order to watch your footage.
Once you have selected the appropriate audio playback software and display device, you can then enjoy your media files in whichever way suits you best. You can listen to music on your PC or laptop, watch videos on your TV, or view photos on your external monitor. Whichever way you choose to enjoy your media, make sure that you have the right combination of software and hardware to suit your needs.
3.3 Identify the settings which could be adjusted to improve the quality of presentations
Most people give presentations in the same way, regardless of the situation. They might adjust a few settings – contrast, volume, sometimes brightness – but for the most part they rely on the same set of defaults. This can be a problem because different situations call for different types of presentations. In order to make sure your presentation is effective, you need to adjust your settings accordingly.
There are six main factors to consider when adjusting your settings: contrast, volume, visual elements, sound elements, pace and rhythm, and environment. Let’s take a closer look at each one.
Contrast: This is the difference between the lightest and darkest parts of your presentation. If your contrast is too high, your audience might have trouble seeing your slides. If it’s too low, they might miss important details. The best way to find the perfect contrast is to experiment with different settings until you find what looks best.
Volume: The volume of your presentation should be loud enough for everyone in the room to hear, but not so loud that it’s jarring or distracting. If you’re not sure how loud to make your presentation, start with a lower volume and then increase it until it feels comfortable.
Visual elements: Your slides should be clear and easy to read. If they’re not, your audience will have trouble following along. To make sure your slides are easy to read, use high-contrast colours and simple fonts. Avoid using too many visuals on each slide, and don’t overcrowd them with text.
Sound elements: In general, you should only use sound effects if they enhance your presentation. If they don’t, they’ll just be a distraction. When using sound effects, make sure they’re high quality and not too loud.
Pace and rhythm: The pace of your presentation should match the pace of your audience. If you’re presenting to a group of people who are familiar with the topic, you can move more quickly. If you’re presenting to a group of people who are new to the topic, take your time and explain things thoroughly. The rhythm of your presentation should be smooth and even. Avoid starting and stopping abruptly, or speaking too slowly or quickly.
Environment: The environment in which you give your presentation can have a big impact on its quality. If you’re presenting in a noisy room, try to find a way to reduce the noise. If you’re presenting in a large room, make sure everyone can see and hear you. And if you’re presenting in a small room, try to create an intimate and inviting atmosphere.
By taking the time to adjust your settings, you can make sure your presentation is high quality and effective.
3.4 Adjust playback and display settings to enhance the quality of the presentation
It is possible to adjust the playback and display settings on most presentation software programs in order to enhance the quality of the presentation.
By using the playback controls, you can start, stop, fast forward, rewind, and pause the presentation to watch the content from different angles or at a different pace.
Additionally, you can use the sound controls to adjust the volume and balance of the audio in the presentation to suit the audience.
The screen size settings allow you to choose between thumbnail, quarter screen, and full-screen mode. This can be tailored to suit the viewer on many platforms. For example, on YouTube, you can watch the default screen size, widescreen or full screen to enjoy the content any way you wish.
Lastly, the visual settings let you change the contrast, brightness, and colour/black and white ratio of the presentation. This can help to make the presentation easier on the eyes of those who are watching it.
All of these settings can enhance your experience when viewing a presentation and can help to make the content more enjoyable.
