Adobe Premiere CC 2020 Audio Out of Sync After Export

Hi roycefilmmaker (and other),

I'm so sorry about your specific issue. These past months, I have found that Premiere Pro can play back most kinds of H.264 footage (especially with proxies). However, when exported to H.264 or HEVC at 4K or 8K quality, some computers might not be powerful enough to actually play back the resulting H.264 file. You can test it out a couple of different ways to make sure.

One way to test this: upload the file to video file sharing site. Any of them will do. If your audio is playing back in sync in the uploaded file, then indeed, your hardware is not powerful enough to simply playback your H.264 or HEVC source file.

Another test: It just may be that you need to export a somewhat smaller file, say in HD quality, in order to play the file back smoothly. If the resulting HD H.264 file plays back smoothly, your hardware isn't powerful enough to play the 4K version. You can still upload your 4K, though!

Let me know if that not having a powerful enough computer is, indeed, the case. 🙂

If you are still running into audio sync problems after uploading the file to YouTube, Google, Vimeo, or other such site, please create a separate post from this one. We will try and lend further advice.

Thanks,
Kevin
