Um...this could very well be the biggest newbie question ever but...is it possible to...compress an AVI to an MPEG...if the AVI is already compressed with a Divx? Please say it's possible...lol.... :oops:

Yes its possible... though not recommended. Why would you want to compress something TWICE?? Thats very bad.

Might be because he wants to send it to someone who's computer can't handle DivX very well.

Umm...well, get this: I'm using Adobe Premiere, and I recently finished my first Vid. Many thaks to this site for that...heheh, anyway, I just got done putting together my second...and it being much better than my first, I decided to waste no time and just export the sucker. It seems, if I export it Uncompressed (Like I did with my first) it comes out like crap. It skips, and the music doesn't play right...and well, it's just crap. I export it with a Divx, and it works fine...it's just........huge. Who the heck needs a 200 MB+ Vid.......not me that's for sure. Geez...I still can't figure out why it comes out like crap if I export it without compression...it worked wonders for my first video. I just exported it uncompressed, and than I just compressed it to an MPEG afterwards. It's a nice 17 MB...now why can't THIS vid just be good...and work...?

Most computers can't play uncompressed video properly. There is just so much data involved, most hard drives will not give the steady rate needed for pure uncompressed video viewage. I would take your uncompressed video and convert it to something like XviD or DivX using VirtualDub.

Premiere does not allow for GOOD audio compression, so if you in DivX from there, you're going to get uncompressed audio w/compressed video, which in many cases, the uncompressed audio is LARGER then the compressed video. So definitely use VirtualDub and make sure you compress the Audio as well as the Video.

I'm with Klinky on this one, and it's actually what I prefer to do. The problem is not premiere exporting crap video, but your computer being too crappy to play it. I say that with sarcasm though because to play uncompressed video you HD and your system would have to be able to systain a transfer rate of over 50MB/sec. Needless to say, that's insane. Uncompressed video isn't meant to be viewed, it's meant to be a lossless render so you can stick it in another program and edit, and not worry about loss of quality between renders. what I'd recommend is mpeg-ing that sexy uncompressed clip you got rendered as that IS the best source possible to work with.

as for audio, premiere actually does support MSADPCM, which is only 4 bit audio, but is not all that bad. Otherwise, you have to export uncompressed as anything else will return a retarded error (error -1: possible cause disk full?)
