I have had this problem on and off for the past few months, but I've always been able to troubleshoot myself. This time, I have a motion graphics video rendered out of Ae with no issues. I dropped that video into a sequence in Premiere so I could add music underneath. When I export from Premiere, all of the audio seems to have been replaced by the most awful digital distortion you've ever heard at the highest possible volume. I made sure to match up sample rates and everything. I'm rendering h.264 with the preset "Match Source Medium Bitrate." Please help! Thanks!
What file format is the added music?
.mp3 with a sample rate of 44100 Hz
Convert it to a wav file before importing into Premiere Pro. Premiere Pro can sometimes have wonky results when using mp3 files.
When I attempt to convert the files, the problem is showing up in Audition as a flat red line where there should be audio. No matter what format I use, I can't do anything with this audio. The problem exists for both .mp3 and .wav files. I haven't tried .aiff, but I bet it will have the same result. This isn't the only project where I've had this problem. It happens almost every time I use Premiere now. Is there an ingest or import setting that might be causing this?
Go back to the original source music, not the converted MP3.
I did that, and I am still having the problem. I think it's localized to my computer because when I tried rendering on a different machine, the issue wasn't there. Using a different computer for rendering is not a permanent solution since I had to take up someone else's computer and time. Also it is a company issued laptop that I'm working on which means I'm kind of stuck with it.
I figured it out. I did have a sample rate mismatch issue. However, I thought Premiere was supposed to automatically conform to the lowest sample rate. Is there a conform setting somewhere that I could check to not have to go through matching that stuff up every time?
I can only say that I've been using 44.1 kHz music in 48 kHz sequences for 15 years and never once had a problem doing so.
Is your audio gain up high? When I changed my audio gain from +20 to 0, it fixed the problem when exported.
