Playback speed of ProRes 4444 file
I've created an animation in Motion that I want to use under a lower third. I basically followed this tutorial (except that I use Motion).
The exported ProRes 4444 file does not always play reliably though. When mimoLive is started fresh it's all fine. But after a while the playback of the file seems to slow down. Causing the lower third animation to get out of sync. Also when I play the file in a simple Placer layer it also slows down. Also it doesn't start immediately when I put the layer live. It first shows a few frames of what currently is shown in the preview windows before it restarts from frame 0. If it restarts at all.
I'm using a 2016 MBP so I think the hardware should not really be a problem (I hope). The render performance meter does not show any issues or delays.
The source file as generated by Motion can be found here.
A video demonstrating the problem can be found here. The first two animations are fine. The last part of the video shows that the animation video plays out of sync with the text animation.
Am I doing anything wrong?
