Cause There may be too many video devices between your video source and destination, or one or
more of the video devices may be degrading the quality of the stream. Adapters, long cables,
cable extensions, and improper connections can all affect video signal quality.
1
Solution If possible, use fewer connections. For example, don’t use cable extensions.
Problem No sound or sound is distorted or too loud
1
Cause Your capture settings may not match your audio input.
1
Solution Make sure your capture settings are set to capture the proper audio source.
2
Cause Audio cables may be loose, or the audio output device may not be properly connected.
1
Solution Make sure you’re using the correct connectors, all connectors are properly fastened, and that
all power cables are firmly in place.
Note: Jerky video may be the result of slow recording. Slow recording causes frames to be
dropped (frames aren’t recorded). If jerky video is caused by frames that were dropped
during recording, the problem can only be fixed by recapturing the video under better
conditions or with different video settings.
