MP4 Exports and Transcodes Out of Sync
Version 25.1. Roughly a full second after 20 minutes. Because there is little hard sync in these shows, it’s difficult to evaluate drift. These shows are 5.1 source to 5.1 MP4 and this may be specific to 5.1 audio. I have not tested stereo. Quicktime ProRes export is fine, in sync, but transcodes from the ProRes masters using Encoder are similarly out of sync so this appears to be an encode issue not a source-side issue. Also two different source sequences, though both are long-form, UHD, 5.1. I’ve tested playback with Quicktime, VLC, and in Premiere. All look the same.
These same shows were previously exported from v24 so this appears to be a new issue with v25.
Is anyone else seeing this?

You could completely delete all the cache folder and try re-encoding. 5.1 does gets me into problem sometimes. Try changing the audio codec for mp4 encoder.
