Web Video Quality Considerations

From: to-3gp.com
Some things to consider when screencasting and creating web videos.

These factors help to determine the type of video that you are doing as well as the final product. If these factors are off any, then you will end up with a lousy video.

So make sure that you understand the factors that are involved when screencasting and creating videos and how these factors effect how your video plays.

Bit Depth

Bit depth is one of the factors that come into play when you are creating video files for the web.

To explain bit depth very simply, it is what determines the color resolution in your video.

High bit depths are used when creating large video files. Lower bit depths are used for smaller video files or for when you want control over the color resolutions.

Frame Size

Frame size is also a factor in video files that you will be placing on the web. Frame size of a project is usually equal to the frame size of the final video file but for Internet usage, you will want to reduce the frame size so that there is less data to transfer when the video plays on the Internet.

Frame Rate

Frame rate is also a factor with your video files in that it helps determine the quality of motion in the video. When the frame rate is right then the video will flow smoothly and when it is off the video will appear choppy.

Frame rate of the project usually should also be equal to the frame rate of the final video file but again for Internet usage this is also not the case. Frame rate for web videos should be lower so that it helps with compression of the file.

Compression

Once your video is complete and you are ready to place the video on the web, you will need to look at the compression.

Compression takes a video file and compresses it to a smaller size to allow it to play on a web page without pulling a lot of bandwidth. The problem that some people face with video file compression is finding the right amount of compression.

If the compression is to low, the data rate will be too high which can cause errors. If the compression is too high then the date rate will be lowered to far causing the picture quality to lousy.
