Xvid avi to mp4?

Using ZarxGUI, could I do this without (much) video quality loss or would I want to first make it uncompressed with VDubMod?

What reason do you want to convert it for?

And when you say "first make it uncompressed", do you mean convert the xvid to an uncompressed file? Because that would be pointless.

I was partially curious and partially wanting to clear up some room on my computer, which I could do by making dvds, but I tend never to watch them again once I take them off the computer.

It seams so pointless. If you recompress something you loose qualtiy and maybe need more filesize too. Just keep them in XviD. That´s one of the best things you can do now.

Not really. Not even when you set the quality settings of the encode really high.

Well, if its just for your personal use, try it and see. Only you can decide if the quality is suitable for you.

MP4 ≠ H.264

If you need it in MP4 for some reason, then just remux the thing with MP4Box (or YAMB). It won't lose quality, since it keeps it in ASP.

x2 . That way you'll just waist your time,since uncompressing doesn't improve the quality..

x2 here too. H264 may be placed in .mkv too,or even .ogm(though that's very rare). Outside of this side,most popular h264 container is .mkv , not .mp4.

Since the only way to compress trough Zarx264 is AviSynth,then you can just filter them a bit more.

I agree. Even though I tried recompressing few old AMVs,just to save some space and increase the quality,I still deleted new versions,since I like the originals and I just want to keep them as they are. There's no real need to recompress anything.

Unless, of course, you want to play it in a portable device of some sort.

If you recompress you'll still have all the compression ugliness of XviD, plus more new compression ugliness from the AVC compressor. You could filter the videos, but it seems a big waste of time for saving perhaps 500kB per minute of video...

I do it, but only when I'm know the quality won't suffer and the size will go down. If I can't make both of those true, I don't do it.

By this I meant Uncompressing it and Compressing it again.

Unless of course you use shit load of filters and then create a 2nd pass h264 file,it can look way more beautiful than before,but I agree with you,that's just a waste of time.
