use DynamicLink to take your project over to Encore, and then set Encore to use AME for transcoding. Encore will automatically use AME (the best render engine) to get the best possible bitrate for the length of footage on the particular disk you're working with. Takes all the math and guesswork out of it...
still fit on one SL DVD?
Why SL? At that length, a DL is definitely called for to maintain quality.
Primarily because I'm not sure my duplicators can handle DL disks and I've never used them before so I don't have any in stock. With 200 copies going out I really don't want to have to burn them individually.
2 pass variable rate.
Using dolby stereo can free up space for more video bitrate on the disc.
AME has a good mpeg2 encoder, you can't do a lot better on a SL disc.
Well, using the DynamicLink method David mentioned I was able to get it out the door and the client was happy with the result. The original footage was all good enough that it stood up surprisingly well to the lower data rate, even though it was all action scenes, mostly in slow motion.
I'll look into DL disks and experiment a bit with them; I just didn't feel that it was a good idea to experiment when I was on a deadline... the disks have to get delivered tomorrow and it takes a while to run off, print & package 200 copies. What a fun day I have today with that.
Thanks for the suggestions guys.
