audio not exporting with H.264

[John Pale]

Strange problem. Try deleting the media cache and letting it rebuild.

That’s a good tip, and I left that off my list, because it’s been a routine practice for me since switching to Premiere to trash my renders and caches at any sign of trouble.

I did try that (again, after reading your post) and the missing audio persists.

Pr corrupting its own preferences and caches had been a persistent problem up until the last major build or two. I haven’t noticed it as much in the past year or so.

If you’re on Mac, you should know that besides storing caches in the location you choose in the Preferences, Pr also stores caches in the default location, which on my Mac is in User>Library>Application Support>Adobe>Common>Media Cache. If you don’t know about it, this folder can get large over time. I made an alias of the Common folder on my Desktop. The PTX and Media Cache Files folders can also fill with files. I empty them all between projects, and often during projects, when issues like this manifest.

I also keep an alias to my Pr Prefs on my desktop, and delete those at signs of trouble. After building a clean set of Prefs, I suggest you zip it in the folder it resides, so that you can restore them easily after trashing the prefs you think may have gotten corrupted.

I solved it. It was one of two things:

I had reversed a sound effect (Clip>Modify Speed / Duration), and I had also used Zynaptic Unveil VST on my VO, which was recorded in a dojo.

By exporting my reversed effect as AIF and importing it back and replacing in my timeline, and deleting and re-applying Unveil, my exports have audio again.

Thanks, John Pale, for chipping in.

i am having the same issue.. working on a feature with 20+ audio tracks, lots of action effects like bullet hits and whizzes are not exporting.. i tried to export just the audio as a wav and overlay it, that didnt work either.. we have aif and mp3 files for the effects and music.. i cant imagine sitting trough and replacing all media with different formats.

If our issues are related, note that it was just one audio clip in my Sequence that was causing the entire audio track not to export. So, if that’s meaningful, look in your Timeline for clips that may have third-party effects applied, reverse or speed varied… non-standard or non-native stuff, and then either re-apply or do something, anything different.

I’m assuming you know about the other routine Pr troubleshooting tricks I already mentioned. Deleting prefs has solved 90% of my Pr issues.

I recall a few years ago having a job-stopping issue that was solved by removing all my FilmImpact third party transitions, and re-applying them. Also, copying my whole Sequence and pasting into a new one. Stuff like that.

I hope that’s helpful.
