Exporting an HD sequence in and SD world
 

Hey everyone, I've got an HD sequence that I need to export. The problem is my edit suite at work (Avid Media Composer Adrenaline 3.1) is only set up for an SD workflow since it's mainly used for news editing. I can't even tell you in detail what I've done(so much stuff!) because I've been trying for a week to get it off the system and onto my 750GB external hard drive. I need to burn this onto a DVD for a client ASAP. Any help would be greatly appreciated.

One typical method is to export from avid as a quick Time Reference. This is a small “pointer” file that references the original Avid media on your hard drive. Next, using Sorenson Squeeze (or Procoder or others) you import the QT ref file and create a standard def mpg file that can be authored to a DVD.

Hi Terry, I did try to do this but it gave me a message about long GOP files and it wouldn't let me export using this method. Is there some other way of using a quicktime reference? I selected my sequence, chose export and tried quicktime reference but got this error message.

Long GOP error
 

Hi Darryl,

To avoid the error do a video mixdown before export. That should do it. Also, read this thread and watch the tutorial video.

Good luck,

Darryl,
You and Jeff are correct, HDV will not export as a QT reference, and a video mixdown will transcode the final sequence to fix the problem. I personally like to ingest raw HDV media and immediately transcode to DNxHD145, and then edit with HD145 media. This takes less CPU, but much more hard disk space, and is ready for QT Ref export.

Thanks guys for your help. I'll try all your suggestions ASAP!
