How do I resize an .mpg file captured in ATI MMC7.6?

[Emanef]

I captured a movie at a fixed constant bit rate of 9, with the intention of being able to use TMPGenc to resize to fit on to a dvd-r (so as to maximise quality by having the highest vbr possible in the space with the movie time, etc). However, I can't get TMPGenc to work! Damn thing! It crashes as soon as I select the .mpg file (mpeg1 capture at 720x576).

What else will let me resize it to squeeze onto the dvd-r? I tried Rempeg, but that wouldn't work. Could it be the captured file that's the problem? Though I was able to top and tail it with MyFlix, so must be a valid mpeg1 file.

Em,
very interesting issue. I cap with mmc 7.6 @ 9 to 10 bits, in mpg2 dvd res, and have no problem rendering or importing to a lot of encoders.

Have you tried an app like PVAinstrumento?
Are you able to recapture using mpg2? Or will the encoders/authoring apps accept de-multiplexed items for you to render?

If not, there's two things i'd do. Look on over at the guides here,
http://www.vcdhelp.com/vcddvdr.htm
and/or the guides over at doom9's site for any guides that may detail mpg1 to dvdr
http://www.doom9.org/mpg/tmpg-dvdencoding.htm.

If it was mpg2--it be easy to use dvd2avi to create a project file and get the audio 'out' and use in say, tmpgenc. Have you tried parsing the file thru virtualdub? Or try DVD2SVCD and see if it accepts the file and if it lets you encode to dvd compliant mpg2 files. I've seen the settings for it but never tried it .

I'd starting capping at mpeg1 because I was having problems with TMPGence with Ati's take on mpeg2. Perhaps I should give that a try again, and try a few other settings. I don't use the default DVD setting, as I'd rather cap at constant rate to give the best results when resizing (I don't actually know if it makes any differance, but logic suggests that a file fixed at 9mbit recoded at vbr to fit a size would give better results than one that's already subject to the constant changes and lower bit rates of a vbr cap).

To be honest, I'd rather not have to be converting to avi or splitting a/v and rejoining if possible. I tried the Doom9 link, but it was down, so I'll try again later.

Just tried a short capture in mpeg2 with MMC and TMPGenc did work with it! I had to change the extension from .mp2 to .mpg though.....!

Thanks!

Now just need try and recode the movie I recorded at mpeg 1 to mpeg2 so I can burn it to dvd!

ATI MMC only capturs audio at 44.1 khz. Will this go straight onto dvd-r or does it have to be recoded to 48? Will TMPGenc do this automatically when using the reencoding for dvd setting?

MMC 7.7 can capture 48kHz audio (it also allows interlaced captures) and the default extension is now mpg even for MPEG2 captures.

Excellent! I didn't know it was out! I was still using 7.6.....

Thanks.
