More or Less - Determine the Compression
In the previous two segments you learned that the amount of data received while recording a
video sequence is determined by the size of the video format and the number of frames. The
bigger the video format and the greater the number of frames per second, the more data ac-
crued. But how can you reduce the amount of data when recording a video sequence?
The answer lies in the different compression processes available to you. Some of them are
Windows Standard compression processes. Others are installed with the TV card's drivers and
are optimally prepared for working together with TerraTV+/Radio+.
Setting the Compression Process
1. To set the compression process click on the menu point Options\Compression.
2. Now you can choose a compression process from the list displayed. Depending on the ver-
sion of Windows you are using or the capabilities of the installed video support, you will
find a number of compression processes in this list. Experiment with the different processes
offered and their settings to find the optimal balance between amount of data and picture
quality that is right for you.
3. Confirm your choice with the OK button.
Important!
You can achieve excellent compression with the compression processes Brooktree ProSumer
Video (32) and Brooktree YUV 411 Raw. Files that are recorded with these processes can only
be played back on a system where they are installed or one that supports these two com-
pression processes. If you want to play back the produced video sequence on several differ-
ent systems, then you should choose another compression process. Cinepak Codec and Intel
Indeo are examples of compression processes that are supported on all systems.
