premiere v15.0 bug report, playback via black magic
i7-9700k stock settings
Asus Prime 2390 with thunderbolt
GTX 1080 ti
Thunderbolt ex3 card to UltraStudio Minimonitor via Thunderbolt cable
Ultrastudio to Flanders Display via SDI
I'm working in a 1080p timeline with Red 8k footage @ 23.976. I have proxies attached at ProResLT @ 1080p. Proxies are toggled on.
When I do trimming, i.e. roll, slip, etc. The playback becomes overwhelmed and starts to lag. Overwrite and insert edits are not a problem. If I trim too fast, like lots of trims in a row, premiere eventually crashes, as does the whole system. Guessing it has something to do with premiere displaying multiple frames together in the program window? But these are not transmitted to the broadcast display.
BM Desktop Video stops detecting the mini monitor, and it comes back eventually (but not necessarily as a result of restarts, it's like it needs a few days).
This is a new problem for me. I have just updated Premiere, and I rarely use RED footage (esp. this big), I'm used to Arri or Sony of some sort. The footage size and the new premiere are the only new variables I can think of.
Tried my BM Intensity, same results.
Trims with the Intensity or Ultrastudio unplugged causes no problems, trimming is smooth.
Drivers are updated.
