Question

Premiere randomly leaves out part of the audio when exporting

When exporting a video sequence as H.264 or H.265, Premiere randomly leaves out part of the audio.

This is completely at random as to where it decides to leave out part of the audio. It changes position each time I re-export the file. 
If I keep re-exporting over and over, I sometimes get lucky and it exports the file normally with all of the audio complete.

As you can imagine, its very time consuming, each time I export it takes around 40 minutes and I'm missing deadlines because of it!

I have had this bug for at least 6 months now, have tried multiple different versions of Premiere / Media Encoder / Nvidia Studio drivers.

(I am exporting as H.264 or H.265 files, 3840x2160, 59,94fps, CBR)

Current Software Versions:

Premiere Pro 22.0
Windows 10 Home - Version 10.0.19041 Build 19041
Nvidia Studio Driver 472.84

Hardware:
Intel i7-9700K

Asus Z390A-Pro
Nvidia GTX1080

32GB DDR4

Two 2TB SSD Drives

Hi KennyJapan,

Sorry about this. I would investgate your source media's audio sample properties and see if they match with the Sequence Settings precisely. If they are not matched, you may have issues like this. I like to conform all my audio to the same sample rate and have it match Sequence Settings if at all possible. You can usually adjust these in your camera settings if they are not optimized for post.

Thanks,
Kevin

OK I will look into how I can change the audio settings on these cameras.

before you need to check the camera settings, simply check the audio sampling rate for the sequence and compare it to the sampling rate for the clips.  you can easily access the sampling rate for all your sources in the project/bin panel.    If you need help with that, post back.

Try turning off Hardware encoding in the Video tab of the export settings.

Hi Bob, thanks for your help. I already know its a problem with the hardware encoding, im just trying to find a fix or workaround.
Software rendering my long 4K60 videos is going to take forever which is why I invested in a fast CPU / GPU to hardware encode with.

Hi Carlos,

 

We film weekly videos for a Youtube channel and output in 4K60, H.264 80mbps or H.265 50mbps


We use the following cameras and settings:

Panasonic Lumix GH5 - 4K/60

GoPro Hero 8 - 4K60

GoPro Hero 10 - 5.3k/60

DJI Mavic Air 2 - 4K60

 

This latest video has multiple clips from all of these cameras incorporated into one long 45 minute sequence.

The audio plays back normally when viewing the sequence in Premiere. When exporting, there are random silent parts in the video file. If we export the sequence again, the silent parts move to another point in the video file. Its completely random.

The only work around is to export the audio as one long WAV file seperately from the video.

Then deleting all the separate old audio clips in the sequence and replacing them with the one long WAV file.

you can leave the original audio in the timeline, but either mute those tracks or turn off "enable" for all those clips...\

This way if you need to make changes, you can just delete the WAV file and unmute or enable the original audio clips...

Hi Carlos, Thanks for your reply. I already do clean the cache and delete the previews.

I even delete the cache and restart my computer incase anything is lurking behind in system memory.

I managed to find a workaround to get this "temporarily" working today - I exported the audio separately as a WAV file, added it back to the original sequence and it exported correctly.

 

Obviously this is not ideal because this new WAV file is one long continuous audio file which is unlinked and separate from the original video clips (meaning I cant really edit the video any further without reverting to an older saved version of the project and its original linked video/audio clips).
