I've just received a frantic e-mail from someone who asked a third party to convert his camcorder home movies -- wedding, christenings and so forth -- from VHS to DVD format for posterity.
Something somewhere went horribly wrong -- either the third party did an appalling job and my friend forgot to check, or my friend had to recover the files from a hard disk crash -- and so the files are no longer in a fit condition to be burnt to DVDR.
The VHS originals have since been discarded, and copies on DVDR are nowhere to be found, so the only option seems to be to recover as much as possible, and reauthor the DVDs.
In the worst case, the VOB is not segmented into 1GB files; and none of the DVD images have bitwise-identical IFO and BUP files. On the plus side, as these are home videos there is no CSS to descramble.
My advice to my friend went along the lines of:
1. Unsegment the VOB files with a command like:
copy /b D:\VIDEO_TS\VTS_01_?.VOB C:MOVIE.VOB
2. Use VobEdit to extract the elementary streams (MPEG video, and either MP2 or AC3 audio) from MOVIE.VOB.
3. Use Mpeg2Schnitt to view the elementary streams, in the hope that they are still reasonably intact.
4. If they're unusable, cut out (Mpeg2Schnitt) or recreate (TMPGEnc) the affected bits, or cry.
5. Reauthor the elementary streams into DVD format with IFOEdit.
6. Burn several copies onto DVDR for safekeeping.
Is there any obvious advice that I've overlooked here?
