I finally have some time (lots of it, as it turns out) to do some HDTV to DVD conversion. I am doing the following, and would like others to review and see if I'm missing anything.
1) I am taking 1080i .ts file captured with MyHD and using DGIndex to demux video & audio. More specifically, I am demuxing in segments, to also accomplish commercial removal, so that at the end of this process, I have 15 video/audio segments. I think this also helps with audio sync'ing, since as it turns out, each segment has its one delay.
2) Then, I use the .avs code listed below to process each segment, and use QuEnc/AviSynth in batch mode (very cool) to process all segments. Note:
a) I am decimating, then using QuEnc's pulldown feature (yes!) -- failure to do this yields choppy video in moderately to fast movement sections.
b) I am using a minimum bit rate of 4500 and maximum of 9000 (using QuEnc's default of 9800 yielded bitrates in excess of 10000, which TmpEnc choked at).
c) As a last step, I use TmpgEnc DVD Author to bring in the MPEG2 files generaged by QuEnc/AviSynth (I also have TmpgEnc Editor, but haven't gotten much out of it, since it couldn't mux DGIndex's output).
Comments & suggestions welcomed.
