Hey everyone,
Just wanted to post this because I discovered this recently... I was cutting an interview and had the audio running through a Submix Track (bus) with a bunch of effects on it. All the effects were running through the Audio Track Mixer Window. However, I noticed that when I was cutting my selects, I was getting a very glitchy/stuttery playback. It wasn't terrible when I was in normal speed, but when I jumped to 2x speed, the audio became so warbled and stuttery, I couldn't even understand what was being said.
I checked all my settings and everything seemed to be looking good: Audio hardware was set up correctly, was using Open CL, sequence settings was using prores not i-frame. I tried a bunch of different things but I realized that the effects running on in the Audio Track Mixer window were causing the problem. As soon as I turned those off, my problem went away. This isn't a huge inconvenience to me, as I can make my selects still, but I thought I'd throw it out there to see if there's some geniuses who know what's going on with all that...
Settings....
Footage was shot on ARRI ProRes 422 HQ
I wanted to clean up the audio a bit so I ran it through my standard clean up. (I usually use the Track Mixer Effects because the noise reduction samples the audio from the track as a whole and not the particular clip which usually gives me a better result).
Track 01 & 02 (Audio from camera). Instead of this going to the Master Track, I set it to go to a Bus (Submix Track) where I added the following effects:
Sequence Settings:
1920 x 800
Audio Sample Rate: 4800
Preview: Quicktime ProRes 422 HQ
Maximum Resolution, Maximum Render Quality, and Composite in Linear Color all checked.
High Quality Playback also checked
The only inconsistency I thought might have been there was the Premiere Audio Hardware was set to a different sample rate (44100 Hz), but when I changed it to match it made no difference...
Have something to add?
