Compression Level
Users may select a value between 1 and 9 for the desired compression level
with level 1 enabling the fastest compression and level 9 the best compression.
The most suitable compression level should always be seen as a compromise
between the network bandwidth that is available, on your video picture to be
transferred, and on the number of changes between two single video pictures.
We recommend using a higher compression level if the network bandwidth is
low. The higher the compression level the more time is needed to pack and
unpack the video data on either side of the connection. The compression
quality depends on the video picture itself, e.g. the number of the colors or the
diversity of pixels. The lower the compression quality, the more data have to
be sent and the longer it may take to transfer the whole video picture. If level 0
is chosen the video compression is disabled.
The option "Video Optimized" has its advantages if transferring high-quality
motion pictures. In this case the video compression is disabled, completely
and all video data is transferred via network as full-quality video snippets.
Therefore, a high amount of bandwidth is required to ensure the quality of the
video picture.
The next two options allow you to set the compression level to a predefined
level OR to set a level for "lossy" compression. This compresses is well refined,
but leads to a degradation in image quality.
