Question

Audio pops only in exported video - no audio pop in timeline

Hey all,

I am aware of the zero-crossing problem, and have mitigated that by adding a 2 frame default audio transition between clips that I jump cut (on the timeline the effect is called constant power).

Now when I play the project through the timeline, the audio sounds seamless and amazing, with no popping sound. But when exported, the popping sound returns between cuts.

Things I've tried that didn't help:

- Deleting the audio previews folder before exporting

- Closing Premiere Pro, removing the media cache files, then opening and re-exporting

- Lengthen the audio transition number of frames (from 2 to 6)

- Manually do a keyframe and drop the end of the audio clip to -infinity db

Has anyone encountered issues like this before? Usually just applying the default audio transitions solve all these issues. But for some weird reason, this specific project seems to have problems even after all the above. Can anyone help?

Premiere Pro Version 13.1.0, (Build 193)

I found a fix for this problem. After troubleshooting the problem for several hours, I discovred that the pops and clicks seemed paired with the audio TRACKS, not the clips. I created NEW TRACKS, and moved the clips onto those new tracks and deleted the corrupted tracks, and the problem went away.

Ian34585514yy7i, that makes no sense at all to me, unless there was a difference in the type of audio track, stereo, mono, or whatever... Thanks for posting your solution. Always good to have another thing to try... I do my best to match sampling rate, bit depth for clips and sequences and never see this problem...

Hey I had the same problm. For an ITW we recorded the wireless sound directly on the video rushes. And I did proxy for editing.

I realized that when my timeline was on "proxy mode" everything was great, but my export were having the same problms as yours: audio popping sound.

When I turned my timeline back to natives rushes, I see the same audio problms as in my export ! Furthermore, my audio waveform slides to the left ! So I desactive my video, reajust all my audio cuts and audio fade. (yeah I had to do all of that manually...). And then it worked.

I've had this problem on a project which persisted despite all the above tips.

In the end, the only thing that worked was changing the sequence sample rate (from 48kHz to 96kHz in this case).

That has cleared it up.... so far.

Same problem. Pops on export only, not playing timeline when editing. Different exports have pops in different places. Solution?

I've found that exporting with "software encoding" did the trick for me.
However, I'd love to get an answer to why this is happening.

I ma having the same problem but NOT on cuts. It happens in random parts of the MIDDLE of a clip. I have talent talking on set...and one word will have a little "pop" in it. I export the seuence again...the pop appears somewhere else. It's driving me crazy and Adobe support is no help.

you might try sending the audio to audition (if you have the full suite of apps). I've found it solve a few problems with audio quality...

Does it only happen when going from clip A to clip B, from clip B to clip C, from clip C to clip D, etc, etc? IOW, do you hear the pops only on cuts?

What happens if you use the Audio Track Mixer and add the Hard Limiter to the Master track? (Double click on "Hard Limiter" to open up the dialog below.)

Yep, only on cuts. I usually add a 2 frame transtition between audio clips to avoid this. But the problem still persists when I export (no pops when playing through timeline)

Just tried that. Same problem. Sounds fine on timeline, still hear popping in the final rendered output.

Does it happen both with direct export and export through Adobe Media Encoder?
