Hdv2 ?
 
Where does it say that it is "HDV2" ? It says it uses a cmos sensor that has 1920x1080 pixels, but i don't know if it uses all those pixels to tape. I believe it downconverts to the standard HDV tape format of 1080x1440. However, oversampling, and using square vs anamorphic pixels could potentially improve resolution, and the larger 1/2.7 cmos sensor would improve low light performance. Also the optical image stabilizer is a plus.

HDV1 and HDV2 are just distinctions we use around here. It's just a convenient way to tell 720 from 1080. I don't think the official HDV spec calls it that. But yes this is the already-established 1080 flavor of HDV. So yes it's 1440 x 1080 that gets recorded to tape. Think of this like the native 16:9 on the Canon XL2. That camera has a native pixel matrix of 960 x 480 and yet what gets recorded to tape is 720 x 480.

Wait? Is "HDV2" different than "HDV Type-2?" I thought the difference between 1&2 was that 'type-2' has a longer GOP and different compression rates than 'type-1.' Maybe I'm wrong? For example: JVC makes HDV type-1 camcorders, while Canon & Sony make HDV type-2; type 1 and 2 are not compatible with eachother, so you could not use type 1 in a type 2 tapedeck, and vice-versa.

Maybe I'm making things more complicated than they need to be, and I don't know what I'm talking about, haha.

Same thing -- it's just a way to distinguish the 720 GOP 6 version from the 1080 GOP 15 version.
