Hi everyone,

I'm experiencing some trouble with exporting video in H.264.

When working inside premiere the video and sound are synced perfectly, but everytime I try and export it, the result is totally unsynced. I tried exporting directly through premiere and also through Media Encoder. Even when I  export the audio track alone, it's not synced to the video.

I'm working on windows 10 Pro, And I tried to find answers on the web but none of which helped to solve that.

I hope that someone know how to fix this issue, 

Thanks!

Hello Lina,


Which camera shot the footage? If you acquired the footage with a mobile device, drone, or screen capture software instead of a camera, kindly optimize your footage by transcoding it prior

Check if your footage have variable frame rate

use mediainfo to determine whether your source is variable or constant frame rate
https://mediaarea.net/en/MediaInfo/Download
if it's variable use handbrake to convert to constant frame rate
https://handbrake.fr
and here's a tutorial on how to use handbrake

Thanks a lot for your kind answer,

I shot the video on Sony NX100.

I'll try to check what you mentioned above and see if it'll fix the problem.

Thanks.

Your camera shoots constant frame rate. So that is ok.

Make sure you copy the entire card to hdd first and then ingest via Media Browser.

Post comp specs, Pr build (see about).

Make sure the audio is set to 48kHz in the sequence settings.
