Infuse Pro 6 makes audio gap when I use 1.5x playback in ATV 4K. When I set playback speed to 1.5x, first there is no audio gap but it makes bigger audio gap gradually. A temporary fix to this problem is to pause playback, rewind a couple of seconds then play.
1.25x playback: the same problem appeared
1.75x playback: the same problem appeared
2.0x playback: no problem.
Here are three txt files showing Mediainfo of three source video file I’ve played with 1.5x mode.
I really love to use Infuse Pro 6. Hope this problem disappears soon!
