View Full Version : What ABR to achieve DVD Quality?

Can someone point me to the answer to this basic question?

I'm encoding DVD to AVC using MEGUI. I use a variant of one of the 2 pass "slower" profiles from Sharktooth.

What average bitrate for AVC will provide essentially equivalent quality to DVD MPEG2? I realize there is a lot rolled into what is required, but I'm just looking for a guideline. What I normally do is divide the DVD video size by 2.3 and set the video filesize in the Bitrate calculator and use that as the target filesize. Any thoughts?

I'd think H.264 could do better than 2.3 in comparison to MPEG-2...

Hard to say, since DVDs can be anywhere from 3000-9000kbps. But I'd start by doing a crf 20 or 22 encode with x264; if you use nero someone might be able to chime in with the equivalent. That way you don't have to guess and juggle bitrate and quality; you just encode everything to the same quality, though some will be larger and some smaller.
