I'm exporting animations (frame- or timeline-based) to .mp4 files from Photoshop 22.5.0 on macOS Big Sur on an M1 Mac mini. No matter what settings I pick, there is always a silent audio track. This causes two issues in the iOS app I'm building, which is trying to show these videos:
- The silent audio track interrupts other system audio or video playback.
- The audio track isn't quite the same duration as the video, so it extends the duration slightly past the last frame. This causes a black flash when the video loops, which is undesirable.
Is there any way to avoid this silent audio track when exporting video from Photoshop? I can strip the track with ffmpeg, but would prefer not to have to.
