Ever do one of those things where you master a Pal DVD (25fps) and
suddenly need to dig it out and show it years laster, but it needs to be
in NTSC?
well, if that's the case, here's the easy steps I figured out:
1. Extract VOBs to a single VOB on the HD.
Use DVDDecrypter in File mode, but change the settings so that it
outputs as one file (ie. one VOB for the entire video).
Ignore all other settings.
2. Now, use VirtualDub MPEG-2 version

Open up that big VOB.
3. Select appropriate audio and video output compression settings and
save the new AVI file to the HD.
Here, if you're outputting back to DV format AVI, you simply match
both to the standard specs.
For speed, I used PicVideo's MJPEG encoder - it's super fast
(alternative is Huffyuv, which is also very fast) at recompressing,
faster than DV output.
Audio, you can go WAV, MP3, AAC, etc. whatever you prefer. WAV will
retain the original sound w/o further compression.
4. Now that you've got the output, you can reencode with any DVD
mastering program you have into a new NTSC DVD disc. (most do it
automatically Pal to NTSC frame rate conversion if you ask; else, dump
into Vegas Video, set the project properties to output a standard NTSC
DV video, and render to DV or final MPEG-2 file to disk, then burn that.)
Whew!
Basically, on a 3Ghz P4 PC, expect to spend about 4-6 hours per hour of
original video to process from 1-4 above.
Why the world never settled on one video format is beyond me.....!
