Target file sizes way off

Hey everyone, been searching for a while and haven’t found an answer, so I’ll ask here:

I’ve been using DVDFab for a while now to rip my old DVD collection, and have just recently noticed that on some DVDs which I use DVD to Mobile to convert to generic.avi.h264.audiocopy. I leave all of the settings (resolution, aspect ratio, framerate, etc.) on defaults, but adjust the Fixed File Size to 700mb, intending to later copy the AVIs onto CD-Rs for my road-trips with the family (CD-Rs with little kids are easier to replace than original DVDs or DVD-Rs :stuck_out_tongue: ). The problem is once the rip is done, the output file ends up being anywhere from 800MB to 1.3GB!

I’m using DVDFab 6.0.7.0, and here’s the settings from one example, Alien:


But here’s the MediaInfo from the end-result:

Is there something I’m missing that’s causing DVDFab to go waaaaay over the file size I tell it to?

Try using the other english sound track (not DTS) and uncheck the subpictures you don’t need. I never use DTS or any subtitles and mine come out within ± 20 MB.

Unfortunately, that didn’t help much.
Only the English subtitles, non-DTS, and set target size for 680MB.


Result: 795MB (115MB above limit)

I don’t own that movie so I can’t experiment for you but would advise that you come down on the frame resolution, that will the file smaller and turn off the “extract to idx/sub file” unless you really need it.

Well I’m experimenting around with different codecs. Tried DivX with 128KBps MP3 and it came out at 656MB when the target was 680MB. I think I’m just asking too much to have an Audiocopy and H.264, so like I said, I’ll be tweaking it around a bit, see what works best and gives me a good balance of quality and size.

Thanks for your help!

Sound like you found the solution yourself, but you are welcome for sure. Try Xvid, I like it better than Divx myself.
