The real quality hit is simply in that first in-camcorder compression, not in the next one. For higher formats than this, uncompressed RTV would offer an advantage. So see, the old adage 'compression sucks' isn't as true as people used to believe, especially if your source is DV/DVCAM/DVCPRO25. Of course, effects and other things composited would make the second encoding more lossy, due to the new high detail stuff added and thus having to be thrown away. This is based on if you did nothing to the clip. After you take that clip and decode it, and then re-encode it, it's going to compress VERY easily, without needing to throw away much more stuff at all, since the source is now VERY clean to compress based on what was thrown away in the first compression, since that high detail never came back. This is where the majority of 'lossy' compression happens, right in the very FIRST encoding. This is done the first time you compress to DV, typically in your camcorder. It is basically because of the following: All DV compression codecs are gonna throw away high detail stuff in order to compress the video. Usually they had to compare dozens of cycles to see differences. More importantly, a long time ago I read a few white papers from manufacturers on why their DV codec was better than someone else's and such, and what I discovered, was that if you're only doing a few compress/decompress cycles, it's really not that big a deal. I don't notice any quality hit doing this.

Then from this I can firewire out a master DVCAM tape with a DV utility program or encode the Type-2 DV file in TMPGEnc. My normal practice for EVERY project I do is to bring in my DVCAM/DV source video as native DV, edit it all in VT-Edit, and render it all out as DV. Then the better color space would make the compositing color results better.īut here's the thing, based on my own experience of what I've been doing for years, I don't think you should worry about it. The only way it would 'improve' what you would get versus just re-encoding it to DV is if you were compositing it with 4:2:2 video clips from other sources or LW or something like that. IOW, for something that is already 4:1:1 color space 5:1 compressed DV, saving it to a codec that is 4:2:2 color space 5:1 compressed wouldn't make much difference, and can't improve it.

Think of it more as something to use where you would have used the PicVideo M-JPEG codec in the past. Well, I honestly see the new codec being mainly used for high quality analog video source digitizing or higher color space and lower compression digital video source digitizing.
