Lossless

Lossy
sliders. Moving the sliders towards speed and compression reduces delay
and increases the frame rate at the cost of more noticable artifacts in the stream. Moving the sliders
the other way reduces frame rate, increases delay but improves picture quality.
Troubleshooting tips
Here are three typical reasons for adjusting web broadcasting compression:
l
If you have a slow Internet connection or if viewers of the web broadcasts notice delays you can
increase lossless or lossy compression to reduce Internet bandwidth usage.
l
If viewers of the web broadcast notice poor image quality you can reduce the amount of lossy
compression.
l
If the video capture workstation CPU usage is too high during web broadcasts or if viewers of the web
broadcasts notice delays and you have determined that the delays are not caused by low Internet
bandwidth. The delays could be caused by high CPU usage on the video capture workstation resulting
in the video capture workstation not being able to process all image data. Lossless compression
increases CPU usage, so you can reduce CPU usage during web broadcasting by reducing lossless
compression.
Note: You cannot change web broadcasting compression during a web broadcast. You must stop
the broadcast, adjust the settings and then start the broadcast again.
