Hello all,

I'm testing out sending SRT feeds to a Nimble server in the cloud and am noticing severe artifacts of the image when I get the return feed. Research tells me that this is caused by the bitrate at certain points of the stream being much lower than the Constant Bitrate being encoded and buffers would help alleviate this. Are there any options/settings/parameters in vmix that might help to reduce this issue?

SRT Settings:
- Type: Caller
- Latency: 160ms (RTT=30ms)
- Quality: H264 15mbps AAC 128kbps (high bitrate needed for quality recording in nimble)
- Hardware Encoder: OFF

Here is an example of what I'm talking about:

Thanks in advance!

As a test lower your bitrate to say 3.5mbps

This is due to packet loss due to insufficient latency configured on the SRT stream, so that value will need to be increased
until the issue is fixed.
