Frames per second are lower than
expected.
The following tips can help improve frames per second (fps):
1. Increase the Limit frame rate value and/or decrease the
Bitrate value in the Encoding menu. See Adjust video
quality .
2. Reduce the number of actions happening simultaneously
on the system (i.e. if streaming, recording, and copying
files, consider waiting to copy files until after streaming
and recording are complete).
3. Enter a low negative value (i.e. -5) in the Frame Grabber's
Vertical Shift field.
4. Reduce the number of channels encoding data.
Stream won't play in my media player or
browser.
Verify that the Stream Type matches with the media player used
and that you have the correct url or SDP file for the player. See

If you still cannot see the stream, try disabling your local
computer firewall.
If the issue is still not resolved, contact Epiphan Support at

The following tips can help diagnose image problems:
1. Ensure the source resolution is used as the output or
recorded resolution. Up-scaling and down-scaling can
affect picture quality. See Upscale or downscale your
video image .
2. Increase the Bitrate value and/or decrease the Limit
frame rate value in the Encoding menu. See Adjust video
quality .
3. Check network settings including filters, routers and
application settings. Packet loss can result in stream
failure.

see if the system is out of disk space. See Check disk storage
space and File Maintenance .
