Compression
When shooting with the DVX100 to mini DV tape, Is there any compression of image from what the camera processes to what goes on the tape or is this uncompressed. I know that compression happens when you digitize to a computer but is there any compression from camera image to the mini dv tape. Thanks

Of course- there is DV compression. That’s what all DV cameras use. There is no additional compression when you capture to computer, provided you are going via Firewire you are getting a 1:1 digital clone of what’s on the tape. You add additional compression whenever you add anything in post- like a transition, color correction, title, etc. Here are the specs for DV:

Noah hit it spot-on. Just to add… the image sensors on the camera do create a beautiful uncompressed 4:2:2 image. If you take the live feed out of the camera (like S-Video), it’ll give you an amazing shot that is superior to what you get on DV tape (if you don’t mind the chrominance channels being smushed together). Some people will take a live feed for chroma-keying and capture it direct to disk. Doing that with the likes of an SDX-900 and using its SDI output will give you full 10-bit uncompressed 4:2:2 video. Delicious.
Death to tape. Cheers for P2 technology.
