So I was having serious playback issues with Premiere Pro lately. ProRes and H.264 4k video both playing terribly at 1/2 resolution. I followed all the tips Adobe recommends (clear cache being basically the only one beyond lowering your playback quality). The only thing that fixed it was I found multiple references to Playback issues being related to Audio Hardware.
So I switch my Audio Out (in Audio Hardware in Premiere) to one of my monitors (actual PC monitor). Now my footage is playing smooth as butter. Previously I was sending audio out to my Motu M2 audio interface. That interface sends audio to my Studio Reference Monitor speakers and Reference Monitor headphones. It also is the IN interface for my XLR microphone for voiceover recording.
Now I found reference to this fix as far back as 2019 (I bet I'd find it further if I kept looking). So what is going on here? Does Adobe not consider this a bug? My monitor speakers are AWFUL, but that seems to be about the only way I get Premiere to actually work as it should. So do I have to pick whether I get to hear quality audio (to confirm it is even worth using) OR quality video playback?
And please don't try and pass the buck to Motu on their audio interface. I truly doubt everyone who has run into this is running the exact same Audio interface hardware.
- DCI 4k ProResLT footage (GH5 recorded via Atomos Ninja Inferno)
- DCI 4k BlackMagic RAW Footage (8:1 BRAW - BlackMagic Pocket Cinema Camera 4K)
Oddly enough the only footage that played even close to smoothly before the Audio Hardware setting change was the BRAW footage. I know it requires the least uncompressing but it is also the most data intensive codec.
Mind you this is the same base hardware and footage I've been editing for over a year. Only in the past few months did this issue start to heavily pop up. The GPU is the only new addition, but I actually bought it in part because I hoped it would fix this issue. It made zero difference.
Bueller? No one has any input? Got a reply from an Adobe Employee in moments but nothing for 2 weeks after?
14.9 update has come out. Same problem persists. Found people as far back as versions in the 13s saying they had this problem. It seems to be a known issue with various Audio Interface units. Are we supposed to edit videos without quality audio output?
