I am also finding problems with audio playback when using Audio Movie CHOP connected to timecode driven Movie File In TOP. I often get audio cutting/glitching out in regular pulses, several times per second.
I hoped to pinpoint the exact circumstances to define it as a concrete bug but I’m struggling at it, it seems rather unpredictable. I’m tagging along here as it might be related?
I have a chain of 3 timecode CHOPS where the first one is advancing and the next two do simple additions (offsets), with the last one driving video playback. So far I observe that:
Having the initial timecode CHOP as “Locked to Timeline” seems to increase the probability of this happening. Perhaps related to this bug I reported? It seems to trigger this problem even outside my 3 timecode CHOP setup.
Kinda depends on the video, but also appears to happen at random points of the videos, not consistently on the same points of the video.
Adjusting some parameters, such as those on “Hours, Minutes, Seconds…” mode seems to maybe fix it for a while and then it comes back later???
Overall It’s really hard to reproduce and understand. Bottom line is that timecode driven audio playback is still completely unreliable for me
I’m on version 2023.12230, windows 10 machine with Ryzen 7 3700X and RTX 3060.
Seems like “locked to timeline” mode of timecode CHOP is the most reliable way to cause this to happen on my end. It was happening on all videos that I’ve tested. All parameters are default, the only change is using the “locked to timeline” setting. The timeline settings are also default.
Audio driver is default (DirectSound/CoreAudio). (although looking at audiomovie CHOP it is apparent that the waveform is stuttering there before even getting to device out)
I do not see anything of notice in the videos I have tried. They were usually Full HD 1920x1080, either AVC or VP9 with OPUS or AAC audio (most are downloaded web videos encoded by platforms such as YouTube or Vimeo). Various framerates and lengths.
While there seem to have been some nuance in where this problem happens in my actual project if I try to avoid “locked to timeline” mode, using it seems to cause it across the board on all videos.
So it is potentially related to this, but like I said it was not exclusive to only using “locked to timeline” timecode CHOP (just harder to replicate), so perhaps there’s a more general problem?
