Into the HD part I

26 Dec 2007 7:00 (Edited: 26 Dec 2007 7:00)

Both new HD movie discs (Blu-ray and HD DVD) use standards that have existed for very long time (like MPEG-2 video) or are quite young padawans (like VC-1). File structure of HD DVD resembles structure of DVD-Video and it has some same limitations with DVD (pulldown stuff for video). Blu-ray uses Transport Stream files and playlist files (and no pulldown support).

So if you want to copy HD DVD movie to Blu-ray disc or vice versa and keep it compatible with stand alone players, you have to modify the video streams. First option is to re-encode the video, but with HD resolutions it takes a very long time specially if the encoding rig doesn't have enough muscles for the job. Second option is to demux audio and video + add/remove pulldown + re-author.

I tried the second option and you can see the result from picture. It seems that the problem has something to do with demuxing.

I hope there will be soon tools that can handle all these basic operations without problems, so people could make their own Blu-ray and HD DVD movies without too much problems.
