I'm just looking for a simply mpg to avi converter. I don't even know if this is possible..

What I'm doing is... I want to edit some of the mpgs I have. I can edit AVI files in QTpro, but not MPG ones. Versiontracker didn't pull up anything :-(

Maybe anyone else has a simpler solutions?

Oh, also. I did actually convert an mpg to avi with QTpro, but the quality was NOTICEABLY lower...

As a token of my appreciation, I will send the person with the first winning solution (feasible), an invite to for their very own Gmail account...

Thanks in advance!

PS. Did a search already, and didn't really come up with anything...
 
You may have answered your own question. There are various codecs for encoding all these formats, but I've generally found avi to be lower quality than mpeg. I don't know for certain that avi has to be lower quality than mpeg, but I wouldn't be surprised.

If this warrents a Gmail invite, give it to wilwheaton.net. I already have Gmail.
 
Which codec did you use with QT? I used a bunch of different ones when I was trying to do the same thing. Some were really small, but lousy quality. Some were bigger than the mpg file. Some were bigger and crappy quality. There are DIVX codecs you can d/l from places like version tracker that you can add to QT. Don't know if you've tried that yet. You may need to purchase the mpeg for QT thing from Apple. It's like $20.

Plus, are you using Windows, Jaguar, Panther, OS 9? More info might help.

There are Pro apps out there that can do this type of thing. If you're using a Mac and iMovie can't help you, Final Cut or Premier or Cleaner Pro might work. Good luck.
 
More specifics...

iMac 20", OSx....
Hmm.. codecs for Quicktime.. looking into that right now.
 
1. Open MPEG in QuickTime.
2. Go to File -> Export.
3. Choose "Movie to AVI".
4. Click Options.
5. Click Settings.
6. Set the first dropdown to None.
7. Set Depth to whatever you want (Millions is probably OK).
8. Set Quality to Best.
9. Set Frames per Second to Best.
10. Click OK, OK, Save.
11. Be prepared for a BIG file! :eek:

Edit: Pixlet may be a better choice than AVI. While I haven't tried it, it apparently gives smaller file sizes than AVI while still being editable in QuickTime (and QuickTime-compliant apps). Use the same steps as above, except:

3. Choose "Movie to QuickTime Movie".
6. Set the first dropdown to Apple Pixlet Video.
7. Ignore this step :)

bbDEMUX may also be useful, it can split a multiplexed MPEG (ie. one with sound and video) into separate sound and video files.
 
Nice...

Ok Trying this out right now.. I'll keep you guys posted...
 
this is not really plausible...

The original 500 mb mpg movie, turned into a 10 gig beast using this method...

There has to be an easier method???
All I want to do is convert mpg movies, into AVI, so I can edit out some unnecessary film in QT PRO...

Help? :(

I don't mean to threadjack, but once you get the file demuxed, what do you do with the sound? I've used bbDEMUX before and haven't found the sound to be usable. There has to be something very basic that I don't know.
 
A few options.
FFMPEG (registered version) will allow you to do a lot with video. I can take a mpeg2 or mpeg1 and convert to avi. FFMPeg is a fairly simple app that builds upon tools available as open spurce. Its more than that, but its a handy tool to have around.

So, what exactly are you trying to do?

Most people rip DVD to avi. I myself hate this, as avi files are problematic. in my experience, they loose sync with sound, and are hard to work with and cannot be put into a format that a dvd player will play. SVCD and VCD are better choices. I assume you are lookiiing to take dual 800 megs and convert to a single 900 meg avi?
Keep in mind the original source yo work with is already compressed, and another compression will not be kind to quality.

If you must convert to avi, try Cleaner 6 and a lot of time. Cleaner is a fantastic commercial product and will do this, but its slow on most machines.

FortyTwo will convert a number of different sources to avi, but not directly from MPEG - unless they have updated it recently.

Quicktime Pro will convert to MPEG4 which compresses nicely and makes a smaller size and will work with any quicktime user.
 
yup, there has to be something simpler

I guess I was a bit naive, to think that it was so easy. I didn't even know about Demuxing...But, I guess it does make sense...

Again, help or advice would be greatly appreciated.

No sweat about the jacking, flattered that it caught attention :)
