Converting AVI - MPG

Hi i have an avi file which is very good quality i have used TMPGEnc 4.0 XPress to convert it to MPG which took about 2 hours resulting in a 4gb mpg file.

The file seems like its lost some quality though its still fairly good, is there anyway to be sure i have not lost any before i convert to DVD???

Thanks

Please provide more information. An avi file can be anything from good quality dv-avi to very compressed video like divx,xvid. And the source video resolution and runtime is also important to know. You can identify avi with avicodec,gspot,mediainfo,avi2clipboard.

You will always lose a bit quality when converting to a compressed format like mpg.

File : 1.36 GB (1.36 GB), duration: 2:23:06, type: AVI, 1 audio stream(s), quality: 63 %
Video : 935 MB, 913 Kbps, 23.976 fps, 624*256 (2.43:1), XVID = XVID Mpeg-4,
Audio : 458 MB, 448 Kbps, 48000 Hz, 6 channels, 0x2000 = AC-3 ACM Codec,

also does it batter wheather i choose

4:3 or 16;9 as the aspect ratio for the output?

Thanks

Find a better source if you want better dvd quality. Or just get a divx dvd player and you wont have to convert.

Bsically, you're starting out with a file that's seriously compressed. Then you're running it through TMPGEnc and converting it into another format that's compressed also. If you were able to start out with the original high quality source you'd get good results. Remember, garbage in=garbage out.
