We have had exactly the same problem during a few of our past gigs. We use the most up to date version of VMix.

These are some of the log files:

We solved it by running FMLE seperate from Vmix and by switching from a SSD to a normal harddisk and not using the ts but the Mpeg codec. From then on everything ran smooth.

We always have this while recording shows that are using a complex light setup (fast lights), combined by a slightly unstable internet connection.

No idea what is actually causing this problem in our case, but we sometimes faced this problem several times in a few minutes.

Since our streaming is not as important as our recordings, we really would love to see this problem solved.

Hi,

12 Mbps is a bit too small for reliable MPEG-2 recording at 720 and 1080 resolutions.
Try at least 25 Mbps and you should see much better results.

Also the 50i frame rate in the first log file seems incorrect for 1280x720, perhaps it should be 25p instead?

Regards,

Martin
