Choppy RED 8k Footage playback still not fixed in ver. 15.0.0 (Its Been over a year!)

[AzzieScott]

Working with RED footage in 15.0.0 is extremely choppy. Clips will play perfectly in source monitor, but when playing clip in program monitor/timeline the clip is unusable because of extreme stutter and choppy playback. Dropped frame indicator shows a lot of dropped frames. Using the same exact clip in PPCC 2019 plays perfectly in both source and program monitor with no issues or dropped frames. Ive been complaining to Adobe techs and have giving them as much info as possible to help resolve the issue.I have made a video pin pointing the exact issue. Can any adobe  please chime in and assist.

I have this exact issue with Red footage. I'd figured out about switching away from the source tab, but didn't know about the undock/dock trick (thanks for the tip!).

It's been a big pain to my workflow for a while now- is there any sort of update to the fix?

Some audio devices can cause problems. You can try  ASIO4ALL drivers. or select none for audio input devices.
