Hi everyone: I'm a new member and am having sync problems burning BD DVDs. I am using Premiere Pro CS5 for post production. When I input new files from my HMC-150, I am always out of sync by between 8 and 22 frames. I unlink, resync, and relink and everything is fine. I then use Encore to burn the BD DVD and end up out of sync again even though playing in Encore shows it in sync. Both input and output are set at 48K audio. This is probably operator error at my end but I can't figure out what I am doing wrong. All suggestions are appreciated. Thanks. Jon
Out of sync problem
- Thread starter Jon Gallo
- Start date
Is everything consistently out of sync by 8 to 22 frames, or does it happen over time?
Once I had a similar problem in Final Cut on a feature film. It was terrible. I ended up calling Apple support, and they were confused too. I remember exporting the film about 10 times before I got things to work. I ended up changing some settings in my export, and it was all fixed.
I am more familiar with the Final Cut workflow, but I will try to give a few suggestions. Are you sending the project to Encore directly from Premier, or are you doing a full export of the video and then importing that into Encore? I know that seems like a simple question. Although I don't work in Encore, I could see compression problems happening within Encore if the program allows you to compress files that are not yet formated for BD DVDs.
My preferred workflow is: export from my NLE with the codec that I edit in, compress the exported video with a video compression program (using an online bitrate calculator to determine the video and audio bitrates), and then finally import that compressed video into my DVD authoring program.
If you are exporting the video from Premier before compression, does the exported video play out of sync when you view it?

Thank you for the reply and I apologize to all for posting in the wrong forum. It was again a newbie mistake.
My workflow is to save the file using a usb card reader and then import into Premiere Pro CS5 on a Mac. After final rendering I use the File >adobe dynamic link>send to Encore. Once in Encore, I select BD as the format and burn it. I seem to end up about 3-4 frames out of sync.
If I save directly to BD DVD format from Premiere Pro and by-pass Encore, and then use Toast 11 Titanium to save the video and audio tracks separately, I end up about 20 frames out of sync.
I have FCP but went to CS5 since it could work on my files in native format without transcoding. Even using FCP I was getting some out of sync problems.

I am not too helpful for you with Premiere and Encore. If you want to try it in Final Cut, one temporary solution is to export the video using your master codec that is the same format in your timeline--like say ProRes 422. When you do the export select "recompress all frames." Do that export within Final Cut; don't send it to compressor.

That will technically render all frames, even if it is unnecessary. You will probably read people saying that could cause the video to go through another generation. Although that is true on a technical level, it will probably be unnoticeable to you. If you do not want to do that solution, or you continue to have the problem in future projects, try to isolate the problem. Start from the lowest level up: camera->camera settings->capture (and transcode if that is a step)->NLE settings->export settings->compression settings->DVD authoring settings, etc.
I could share so many stories of these sorts of disasters when working on independent feature film. It can be a headache, and the solutions always seem unexpected.

Thanks for the advice. I'm going to try in FCP. Jon

I am shooting non drop frame and Premiere Pro is set for non drop frame. I have isolated the problem to blu-ray. I can burn a regular dvd without a sync problem. I tried to export the video to FCP7 using the export to FCP xml feature in Premiere Pro but it doesn't work. I input the raw video into FCP7, transcoded it and then burned a blu-ray and there were no sync problems. Unless I can figure out what is causing the problems in Premiere Pro, I'll have to recut the video in FCP and loose a couple of days of work. Jon
