When you captures the DV footages to the computer, it already 'coded' as a DV footage, so by exporting it as an uncompressed file 'wouldn't really make much difference'...
I did the same thing as you did before, but then I remembered that if you didn't apply any effects or transition to the footage, exporting it out as a DV footage to add vfx wouldn't be an issue. But to be 'safe' I always has been exporting the DV to uncompress for AE work, until I realized while watching it on bigger screen (projected to a 42' wide screen), it wasn't making a much of a difference... So I started to export the file as DVCPRO50 Codec, which is a bit better than the regular DV25... The size for a dvcpro50 is 50% more than DV25 (or regular DV footage) but it keeps the quality high, this way you don't have to have a lot of uncompressed files. Perhaps that can be an option for you? I would suggest doing some testing to see how it looks on screen, and comparing the uncompressed avi to the dvcpro50 ones. (Btw, I use MainConcept's DVCpro codecs).

For my last big project, we used Canon XL-1 cameras, and exported as DV AVI files. I'm editing in Premiere 6.5*. There are a few special effects, for which I usually use After Effects. My ASSUMPTION has been that DV-AVI is lossy, so when I have a clip that needs an effect, I export from the timeline as an uncompressed AVI, do my effects work on that AVI, and then render to a third uncompressed AVI, which I then import back into the Premiere timeline, where it will, of course, eventually be compressed out to a DVD mpeg stream in the future. Normally, this works fine, but as you might imagine, it does take up hard drive space (this is a 90-minute project and there are a lot of effects). However, I'm getting to a point where I need to apply some atmospheric and color correction effects to larger pieces (and the color correction tools in P6.5 aren't as fun as being attacked by poisonous bees), so, NORMALLY, I'd export the whole scene, fiddle with it in After Effects (or Edius or whatever), and bring the big AVI back in. Big scenes mean big AVIs, and now things are starting to get pretty huge. My question is, am I worrying overmuch about the possible image degradation? IS there image degradation, if I were to, say, export from P6.5 as a DV-AVI, fiddle with it in AE as a DV-AVI, export it from AE as a DV-AVI, and then bring that file into P6.5? 'Cause if not, that sure wuold save me a lot of hard drive space and nervousness. Cheers, Edward * Because that was the latest software I had at the time, and I prefer locking my tools once I start a project. That said, however, if there are no issues with upgrading to CS3, I sure might enjoy doing that. ------------------------------------ Yahoo! Groups Links ------------------------------------ Yahoo!
