Compressing Video Recordings
Creating a recording in Windows (.avi) format allows compression. The settings that affect your results are: compression, movement, and window size.
Compression ratios impact image quality. Lower compression ratios produce smaller file sizes, but also lower image quality. The compression ratios vary depending on the compression program you use.
The key frame rate impacts image quality if you make changes in the graphics area quickly. The rate is how often an exact copy of the screen display is saved. Each frame includes only what has changed since the last key frame. If you have excess variation between frames, lower the key rate.
To set video compression:
-
Select a Compressor (Microsoft Video 1, Cinepak, Codec by Radius, and so on).
To create the video without compression, select Full Frames (Uncompressed): clicking Cancel aborts the recording.
-
Adjust the Compression Quality slider.
-
Type a value for the Key Frame rate.
-
For additional compression options, click Configure. The options available depend on the compressor you select.
-
Click OK.
