Exported audio has 1 frame without sound

I have this big project with numerous files and sequences, and the sequences that go to render comprise nest-blocks (green). They are all placed together with no gaps, below is an mp3 music file cut in the parts where nests meet so every nest is exported with the corresponding part of the music (yellow).

So, I am to export these blocks individually one by one using in and out points. I double-checked it - the markers are placed exactly in the cuts between the blocks - i do it with X hotkey. But in the end the exported videos all have 1 frame with no sound while retaining the full video:

So when the clips are brought back to Premiere and placed next to each other you can clearly hear this 1 frame with no sound.

Why does it happen and how to correct it? I NEED A SOLUTION ASAP!

All the nests were created inside the sequences out of groups of media on the timeline. There was no gaps, the sound met the ends of all the clips.
All nests and sequences are 25 fps. If I export the nests contents separately there’s no issue
All tracks have Premiere own audio effects on them. Removing those does not cure the issue
Clearing the cache does not solve the problem either

Hi @AndrewTheGreat,

Thank you for posting about this issue and providing screenshots. Can you please confirm the following information:

You’re using version Premiere 26.6.3, correct?
For clarity, there is audio in the nests as well?
Can you please note the exact export settings: video, audio, captions, metadata?
- Can you also send us a screenshot of the Media File Properties of the MP3?
  - Matching those specs will help is in a reproduction of this issue.
Does the same issue occurs when exporting through Media Encoder?
Curiously, does adding a fade, cross dissolve or if checkerboarding the files, by one frame resolve the issue?

Sorry for the frustration. I hope the team can help you soon.

Best,

Jonathan

No, its 26/2/2 and I cannot upgrade right now because of I’m midproject and there are numerous issues with missing h265 codec.

Yes there’s audio in the nests + there are multicams inside the nests. The construction looks like this: video + audio synced in multicam > multicam + audio (music) > Nest. The issue happens on every level in mp4.

For instance, here’s a small clip placed between another clip and a nest, ann music on the track below which was cut in the place where this clip ends and nothing else was changed, this part is played back with no stops or pauses, as a whole

so I selected it with X and rendered in mp4 h264 and immediately placed at the end of the same sequence and here you are:

It’s just one frame so no one normally pays attention to it, but when you have multiple blocks of videos that have to be cross-synced with the music, this one frame becomes a stumble block.

The screenshots.

All the sequences are:

The export settings:

The mp3 is now wav and it didn’t change a thing:

The old mp3 was this:

It tried changing the original 48Hz to 44 on export and in vain.

The same happens in Me.

Cannot do the crossfading because the project demands that the music is played back throughout the whole set of blocks of videos seamlessly:

I managed to achieve this by cutting pieces and stitching them with a crossfade in the part where they don’t cross the cut between the clips. So the first yellow small block of the music is changeable like 220 names (the person in the video says “Hallo,*name*” for 220 people) and the 3 (violet) part is also changeable 20 times and it’s the part where I stitched the music.

So you can see the project is complex and every part of it exported to the lengh of every block has this flaw in mp4 and no issue in mov.

Another update: I saved the timeline to XML and imported it to Davinci Resolve and guess what, NO. Issue. There. I exported the files both in mov+prores and mp4 with h264, everything is fine. It’s clearly a Premiere issue

Update: exporting to mp4 leaves these cut ends. Exporting in mov has no issues. My question is WHY?

Assuming that the other audio is 48000 Hz and the .mp3 is 44100 Hz and the timeline/export is 48000 Hz, i would try to convert the .mp3 to 48000 Hz/16-bit and use that instead of 44100 Hz/16-bit.

Import the .mp3 in Audition and hit F11 and rock on from there!
