Please, how to convert m2v back to mpg2..

[Reverz]

My problem is - mostly DVD -> TO VHS ..

I have extracted with vobedit 2 files m2v and ac3
from DVD (i found ac3 is only options - as that dvd was mastered with ac3 only) - and i want to edit them ( in vegas4/5 and then re render to program stream and store it on VHS tape - i will use my sony dvr camera ( like from computer -> CameraTape -> From camera to -> VHS )

but how i can get ac3., and m2v files back to wav and avi or mpg
that i can edit in vegas or what ever other video editor what can support export to camera

T I A

sorry i am new here and please forgive if this was posted in wrong place

m2v is already an MPEG-2 file. It is only the video part. You need to get a program that will mux the m2v video and the ac3 audio into one MPEG-2 file. There will be no quality loss since you are only muxing them, and not re-encoding it. The MPEG Tools section of TMPGEnc can mux m2v and ac3 to MPEG2.

I would try to avoid converting the MPEG-2 into DV format, mainly due to colorspace issues. Remember that DV is limited to 4:1:1. Also since you are re-encoding, the quality will suffer.

You could get an MPEG-2 output card for your computer, such as the Sigma Designs Hollywood card and output the MPEG-2 to the VCR that way. If your GOPs are closed in your m2v file you can edit your MPEG2 per frame and cut frames using a MPEG cutter program so you don't have to re-encode.

If you can't get the MPEG-2 card, then use a good DV codec like MainConcept or Canopus, they seem to give better results than the default Microsoft Codec.

You might want to search the forums for the terms: output to VHS, to see if can find some more suggestions or help.

Thank You very much - Video Dude - :)

That worked very well with TMPGEnc by muxing them into one
mpeg2 proram stream!

Glad you got it working. Your Vegas program should now be able to open it.
