There is a bug with the multclips an its been bugging me a whole lot..
its a 2 camera setup.. i delete the camera audio so there are no 9 audio tracks.. in some cases audio shows in timeline in some it doesnt. everything is synced with plural eyes then i copy the media from there and paste it in the multiclip file.
when i change the settings to ProRes 422 on the plural eyes sequence, preview files are deleted.. and with that the audio waveform… when i trhow the multiclip on a sequence and disable and then enable the multi clip, the audio appears. not in all cases.
