Hey @Neil_Carson – Thanks for the detailed report!
Based on your report it appears that you are experiencing the same behavior that we are investigating as mentioned by Greg above:
There are some details in that thread about updating FFMPEG. I definitely recommend giving that a try.
We also have a ticket open with our development team regarding this behavior. I can’t currently promise and specific timeframes for this solution, but I can say that the team is hard at work on this! I can promise that I’ll be sure to keep this thread up to date as new information becomes available.
Kind regards,
Dylan
