Bluray transcoding support?

There's nothing wrong with MPEG-2 -- as long as you have the space/bitrate. But, AVC very definitely provides superior quality at the same bitrate -- expecially when bitrate is limited.

...but for the time being I would be a little hesitant with a crf>19 (x264) for a high quality 1-pass backupIf the CRF goes above higher because of complexity/bitrate requirements in X264 -- it will do the same in MPEG-2, only with a bigger quality drop.

I noticed that a re-encode of a complex scene using x264 1-pass crf=18 resulted in a higher file size than the mpeg-2 original. Is this an indication that the original suffers from mpeg-2 artefacts which x264 just replicated with high precision?

Probably -- but that would be a wild guess.

Right now the recommended choice is X264. It has lots of flexibility, many options, and is open source. FFMPEG also does H.264, but in my experience is slower (which is interesting because it uses the same engine). Mencoder is another LIBAVCODEC based choice -- but I haven't done any testing for speed.

I´m a week further now, and now I know how to use x264. :) Recoding takes extremely long (CQ, CRF=18), but the result if phenomenal.

I wonder what would happen if the first version(s) of your BD Rebuilder recoded just the AVC/VC-1 stream? (so as to make the total fit on a BD25 disk). Then you could leave the hard stuff (rebuilding of menu structures, etc) intact, for now.

Hey folks.

About x264 vs VC1, wasn't VC1 designed to be less hardware intensive and faster to encode with than x264?
