Hi!

I need some help with live streaming on Vimeo. We’ve been working with a company who wants all their live events to be streamed in Vimeo, and mostly its been ok but its still very bad for a big video platform.

Recently we’ve been getting issues with the stream completely freezing when we cut from one input to another. Looking at the stream health tab in the backend on Vimeo it’s telling me that both the frame rate and the bit rate is all over the place when these freezes happens. Everything in vMix looks good and we’ve never had any issues like these before. In Vimeo the frame rate can go from 17 to 45 in a couple of sends, so something is obviously wrong. We stream h.264 1080p25 in 4,5mb with hardware encoded.

Has anyone else encountered these issues and can help me fix this?

Does the same symptom occur when using the exact same settings streaming to other streaming platforms?

If thats the case, then perhaps try CBR and set keyframe interval to match framerate.

No this is only on Vimeo. We’ve been streaming for a long time and never ever had any issues like this.

One thing that might be the culprit is that we use a Magewell HDMI to NDI converter to grab the output of a laptop that displays a PowerPoint presentation, and both of the last times we’ve had these issues we’ve grabbed MacBook or iPads, not windows laptops which we usually have. Could that for any reason be an issue in this case?
