recipe for compressing an 8.75 hr event for DVD?
on Mar 1, 2011 at 12:34:08 am

I have a 5 part lecture series (a total of 8.75 hours of DV NTSC, SD 4:3 footage that needs to be compressed and delivered on DVD. Each lecture is roughly 1hour and 45minutes. What is the best recipe for compression and how many DVDs should I expect to use? I imagine a box set deliverable is the best, but can I consolidate down to 2-3 lectures per DVD (210 - 315 minutes) without a noticeable loss?

Thanks!

I just did a project like this but had 21 hours of lectures that all fit on four dual layer DVDs. I used BitVice to encode at 3-4 mbps which looked very good. With that bitrate you can expect almost 2 1/2 hours per layer which nets about 5 hours per dual layer disc, enough for your project for sure.

But I don't think compressor is up to the task. It can do it but running as low as 3-4 mbps VBR is gonna look crunchy out of Compressor.

BitVice does this very well. I think Episode 6 with the MainConcept engine can do it as well.

Thanks, Rich! That is helpful. I'll check out BitVice. I was going to use compressor, but good to know it would look crunchy. I'm a dual layer skeptic. Have you had good outcome with them? I worry about the reliability, shelf life and issues with replication.

I have only duplicated, not replicated a dual layer project so I don't know about the issues. With similar lengths of clips for each side, the split point should be pretty seamless.
