Hmm... I have the Mainconcept DV codec installed, and the default one that came on my computer for the built in firewire card. I know they are there and working, because I am able to capture/edit DV video. And other programs are able to use them.. I'm using Carrara 3.04.. No DV compression shows up in theoptions box for AVI files. Exporting as a numbered filmstrip work fine, but I wish I could just export as what I needed... Don't I need to render at 720 x 534 since I'm rendering with square pixels in Carrara? When I make stills in Photoshop or Illustrator for use in Premiere DV projects, I make them 720 x 534, then it gets squashed in Premiere to the right height. Otherwise round things don't stay round.. But I love it....... thanks
