To flush this one out a little bit...

A DVD-Video disc is replicated (literally stamped from a glass master or gold disc master in a dust free environment).  Every copy is the same as the original.  Also, it's assumed that the data structure is compliant with DVD-Video specifications.  Usually, the minimum run is 2,000 discs.  There's always an "overun", so you get more than 2,000.

However, you can build the DVD-Video data structure (the VIDEO_TS folder) without going to replication.  To play this in a DVD-Video player or Blu-Ray player, you would typically burn the VIDEO_TS data to a DVD-R, DVD+R, DVD_R DL, etc.  As long as the player can read the media you've used, the content should play as expected.  These are "burned' or "one offs'.  In a computer, this can play directly from a hard drive.

Apple Compressor has great MPEG2 settings as long as you use the ones that have "best" in the name.  Some encode MPEG2 in DVD Studio Pro which ironically does not have a preset that favors image quality.

And... if you care about image quality, 150 minutes is the most you can cram onto one layer (a DVD5 if you're replicating).

Fun stuff, no?

Quoting Jonathan Penzner <sureal@charter.net>:

Can you explain what a stamped disk is or give me a resource to look up, Steve?

And are you familiar with the plug-in Andrius mentions – the Cinemacraft CCE-MP? Other than hardware encoders, would this plug and Adobe compressor rank highest?

Many thanks,

Jonathan

well the apple Mpeg2 codec won't do the the job unless its pretty much mostly stills. adobe's mpeg2 compressor should do better, as well as some others. it really depends on the motion and content as to what you'll get. a 10 minute long test of actual program should give you a good idea of if it will work... and for compatibility stamped discs are the way to go. it never fails that if I have a problem, its always a sony DVD player...

For 250 minutes on a DVD9 your bit rate would be 4.1mbps for the video assuming you're using .ac3 for the audio.

That's pretty low for compressor even running VBR with a wide range, so you might want to run some test clips to make sure that what you're getting looks decent enough for the client.

If you want to get the most out of Compressor (and you're doing this often enough to justify spending $800) I'd recommend the Cinemacraft CCE-MP plug in. It does a really nice job at the lower bit rates where Compressor often falls down.

Yea, 250 minutes should be doable with mpeg2, particularly if there is a good amount of synthetic footage. I was just providing a bit of an aside.
