Re: DV100 vs DNxHD vs CFHD

The DVCproHD codec is done using 4 DVCpro codec chips, and DVCpro50 is done using 2 DVCpro codec chips. DVCpro just uses one of them :-).

There is a specific data rate that each chip can handle. Therefore resolution of image is limited. 720p is double the pixels of DV, and 1080i is double the pixels of 720p in DVCproHD format.

These 4 chips are not user-reprogamable, so don't expect "upgrades" to them.

As for capturing the "full" resolution - I think you're expecting too much here. Every camera has a resolution filter on the front of it - the lens. Lenses that let more detail through are more expensive. I thoroughly expect that even if you could rig up the camera to capture the full raster, although you'd get more resolution, I severely doubt you'd get more actual real detail. It's detail that counts, not resolution. You can take VHS and blow it up to HD size, and now it has 1920x1080 pixels, but it has no more DETAIL than which it started with.
