I'm having a REALLY hard time getting MPEGS into iDVD
so i have tried converting them in QT6 to MOV files, and it will export the video, but NO audio. Even if i wanted to export JUST the audio it doesn't work. Sometimes QT just crashes


how can i batch convert some MPEGS or SINGLE convert them to MOV format
thanks in advanced

yeah, QT is pretty stupid with MEPG-1. you need to demux the audio first (bbdemux is a good app). You'll get an mpa file, and if you change the name to mp2 and strip the type and creator codes (if any) you can convert it in iTunes

Or, there's MediaPipe, which supports batch processing (by the command line. the app is gui, though), or ffmpegX. Either of those should be able to convert the video and audio in one shot to something iDVD can play

non of these programs support MPEG TO MOV
but they support the other way around

[lucylawless]

what happens if you just open an MPEG and save it as a mov from QTPro?

well, MediaPipe can open anything and save as mov, avi, asf or mpeg, it just can't do the video and audio in one file, yet.
ffmpegX can encode your mpeg to an avi, which you can convert to a quicktime movie easily with Divx Doctor or AVI2MOV (part of Divosx). But the conversions for these will take a long time depending on the length of your movie

So i got FFMPEGX
and i'm trying to do MPEG to AVI so then i can use AVI to MPEG
i get this

any ideas?

hmm. Often times this app will screw up if the name contains an apostrophe or something. Try shortening all the file names like "in.mpg" or something, and put them at the root of your hard drive. Also, do you have a disk called Users? And that ffmpegX.app//Contents... it all looks funny. Try putting your file at /in.mpg and then putting in

/Users/alasar1/Desktop/ffmpegX.app/Contents/Resources/ffmpeg -i /in.mpg -y -f avi -vcodec mpeg4 -map 0.0:0.0 -b 1000.0 -s 640x352 -r 29.97 -g 240 -me epzs -qmin 2 -qmax 15 -hq -acodec mp3 -ab 128 -ar 48000 -ac 2 -map 0.1:0.1 -benchmark /Users/alasar1/Desktop/LT

I'm assuming you have ffmpegX on your desktop and your user is alasar1? I took out that second slash after ffmpegX, but if that doesn't work, try putting it back in.

All the app does is generate these parameters to feed to the command-line ffmpeg app, so use it to get the right settings and then fix the file names if they're not right, get it?

You have to split the mpg's audio / video streams into seperate files and then re-combine them as a mov.
BBdemux will split the mpg streams. I know it works in 9 and I think it works in X.
Open the video (m2v or mpv) in QT and export as a mov, crop or resize to suit.
Open the audio (m2a or mpa) in SoundAp and convert to aif, 16bit, 441000, stereo.
Open the new new mov and aif files in QT. Use add-scaled to add the aif to the mov. Save it using the full save option.
If you have Cleaner it will do all of this in one shot. It's slooow and costs $$$, but it can batch process and the results are quite a bit better.

How do i set this up in Cleaner?
http://www.discreet.com/support/clea...ner&id=734
does that discuss it?
it says
"How do I make a muxed Program stream for MPEG-2 output when I don't see that option available in the Output tab?

The absence of this option is by design when choosing one of the pre-set MPEG-2 settings.

To use this feature, click on the Audio tab and select MPEG Layer 1 or MPEG Layer 2 from the Codec menu. Then click on the Output tab. The Stream Type field will now be present and you can select between Elementary and Program streams."

I've done all these setting, am I missing something? there is still no audio when i follow these directions?
can anyone clarify?

iDVD doesn't accept mpeg-2 input either. it takes quicktime movies and encodes it's own mpeg-2 files, which the user never sees

it's easier to make mov's than mpeg-2's anyway
