working my way through some of this, running into a few problems, but my thinking is that ultimately, it appears they 'we' in Europe seem to be getting better versions of US films in High Def, thanks to SkyHD and Premiere in Germany.
The only problem is of course the speed of these films.
As I understand it, the process should run as follows:
- H264 & Ac3 Transport Stream.ts
- Trim, if necessary with Transport Stream Packet Editor
- Demux using xport
- rename demuxedaudio.mpa to demuxedaudio.ac3
- fix issues with audio stream using ac3fix
- slow down audio to 23.976fps*
- Using an AVISynth Script, slow down, crop, resize your HD Video was needed
- Encode via your AVS file or from a intermediate AVI file to the format of your choice
- Remux audio with video either during DVD authoring or to a standalone file
A couple of points that have come up:
- You may wish to use NTSC audio from a DVD release, in which case you may have sync issues to correct
- Moth3r has suggested using AVC2AVI_mod to wrap you H264 video within an AVI container, although I couldn't get this to work.
*I have read that the trick with the audio is to run the AC3 through BeLight / BeSweet and under advanced settings, set the framerate from 25000 to 23976, but so far this has been unsuccessful. Not being an 'audio-head' I could do with some help on this part.
