Clip jumps at Pause Cue
i have a problem using pause cues in a timeline.
Macbook Pro Retine Mid 2012 Millumin v3.14c Mojave 10.14.6
Macbook connected directly to 24" Screen 1920x1080 50hz
Clip 1920x1080 ProRes 422 25fps
When i use segments, and use the Play Once Mode the clip jumps noticeable for about 2 Frames when running into the pause cue.
I cant see any frame jump pressing pause in Quicktime.
Any Ideas? Am i doing something wrong or is this a known issue? Hardware too old ?
