1. Chapter 9 Integrating Video

2. Digital video is a series of bitmap images that, when played back, create the illusion of movement. The quality and overall file size of digital video is determined by its resolution, bit depth, and dimensions. Getting Started with Video

3. The sound quality of a video depends on the sound’s sample rate and bit depth. Getting Started with Video

4. Frame rate, frame size, and bit rate also help determine a video’s quality and file size, as well as its encoding process, the output of the video to its intended viewing device. Getting Started with Video

5. Video frame rate is measured in frames per second (fps). The higher the frame rate, the smoother the video appears. Getting Started with Video

6. Standard TV video runs at about 30 fps. For a film, the frame rate is 24 fps. For Web videos, average standard frame rates are 12-15 fps. Getting Started with Video

7. A video’s frame rate is linked to its aspect ratio and frame size. Aspect ratio defines the proportional width and height of a video. Getting Started with Video

8. The 4:3 frame rate aspect ratio versus 16:9 aspect ration

9. There are two standard aspect ratios for digital video 4:3 and 16:9. – The 4:3 aspect ratio, in which the frame size can vary from small (320 × 240 pixels) to large (640 × 480 or 720 × 480 pixels). – The 16:9 wide-screen ratio. Getting Started with Video

10. It’s best practice to provide video in various file sizes to accommodate users with differing Internet connection speeds, browsers, and viewing devices (e.g. mobile, tablet, or desktop). Getting Started with Video

12. The bit rate, or data transfer rate, of a video controls the amount of data that the video streams or downloads over time. Bit rate is measured in kilobits per second (kbps)—a rate of data transfer equal to 1000 bits per second. Getting Started with Video

13. Buffering occurs when the rate at which data is being downloaded does not keep up with the rate at which a computer is processing it, so the computer must pause the playback while it downloads the next batch of data. Getting Started with Video

14. Video encoding is the process of preparing the video for output. This process is where you set your video’s frame rate, frame size and bit rate. Getting Started with Video

15. Depending on the use, a video can be encoded using any number of video codecs— methods by which digital video data is compressed and decompressed—and many different formats. Getting Started with Video

16. Common video file formats: – Microsoft Video for Windows (.AVI) – Apple QuickTime (.MOV) – MPEG-4 (.MP4) Getting Started with Video

17. Common video file formats: – Adobe Flash Video (.FLV and.F4V) – WebM (.WebM) – Ogg Theora (.OGG) Getting Started with Video

21. When planning a video shoot you should: – Create a storyboard. Video Design Strategies

22. When planning a video shoot you should: – Get the best recording possible by: using a camera with an audio output to add a microphone. minimizing background noise. doing a camera test. Using a tripod. Video Design Strategies

23. A skin is a graphic element that determines the type and design of playback controls your video will have. Video Design Strategies

24. The length of a video directly correlates with its file size—the longer the video, the longer it will take to download if users view it on the Internet. Video Design Strategies

25. Captions assist the hearing impaired by providing a text equivalent of the audio portion of a video as it plays. Captioning can be a tedious but worthwhile process. Video Design Strategies

26. Video example with captions

27. Transitions are effects that allow you to blend or disguise the motion between cuts of video and title treatments. Video Design Strategies

28. Without transitions, frames between video clips can jump awkwardly from one shot to the next, which can appear jarring to the viewer. Video Design Strategies

29. The Adobe programs for working with video are Premiere Pro and Premiere Elements. Premiere Pro contains a full set of features for the intermediate and advanced videographer. Editing Video Using Adobe Premiere Elements
