Not exactly sure what you'r trying to do but I did a quick test on my MAC. Did a simple little animation with a shere which had Marks "brushed metal" shader applied. Rndered animation and then "saved as" sequntial picts, used "none" in the quicktime plug-in compression settigs option. Seemed to work OK. Perhaps you could use MoviePlayer 2.5 to extract the video channel from your movieand resave from there as another format (make sure you have latest QT extensions but unless you have QTPro you need to use Movie Player 2.3). Also, Apple is offering a free download of iMovie to G4 & PowerBook owners (it also works on G3s). Not sure what that may offer though, havn't had the time to check it out.
