Audio Drift Bluray Export Issue
For a bluray I needed to export. I exported the m4v file (h264 bluray) with a VBR 2 pass 30/35 (target/max). The project and export was at 1080p 23.976. I then proceeded to seperately export the audio as a 5.1 surround 16 bit 48kHz wav, which I would convert into a DTS-HD MA file. But both when I imported into an Encore timeline and played an m2ts muxed file, the audio’s sync would drift off. It was started to become apparent at the 20 minute mark and was extremely bad by the 90 minute mark. The project is almost 2 hours. When I imported the individual files into Encore, the video was slightly shorter than the audio, yet on export they covered the same amount of time. I have used this export out of PPro and import into Encore method many times before, working perfectly, but now has this issue. I’m experienced but I cannot figure this problem out on my own.

I also have just recently been experiencing this problem. I never had it before. But now when I export from premiere pro to H.26 blu ray, the audio is out of sync. It is slightly longer than the video and it drifts. it starts out proper at the begining of the video and then drifts out as it goes.

I’m having a similar problem too… My vídeo is 99,93% smaller than the original timeline… This is: I’ve rendered a 640×274 h264 file… and it was ok… with 100% lenght… but when it cames to blu ray h264, I have this problem… I’ve try it three times… but with exactly the same luck…

I’ve seen that some people, in the net, had this same problem… But haven’t seen any solution… maybe that’s a bug…
…
My project has 1:32:20:15… and the video ends, rendered, with 1:32:17:04… causing sync problems… as the the sound finishes with the same 1:32:20:15…
…
If anyone knows how to help, please do.
