In my book if is not strictly 1920X1080, it's not native. But whatever, I can't get too excited about this. Bottom line as always is picture quality. If they can achieve the best picture quality with 1 pixel or 1 trillion, it's fine by me.

1920x1440 (4:3) - anamorphic possible?
 
Hello all,
If the imager is "native" 4:3 ratio at that 1920x1440 resolution, would it be possible to get THAT full image out of the camera via hdmi? I have a Lomo zoom lens from a Konvas 35mm movie camera that has a rear anamorphic adapter. I would love to be able to use this lens with a DOF adapter like the SGpro or Brevis. If that were possible.....ah, heaven.

Also, would 30p be possible using the HDMI?

I know the guys at reel-stream have the andomeda setup for the dvx100, and are currently working on a similar mod for the HVX200, but I'd prefer a cheap 4:3 "uncompressed" image that could be (presumably) used for amazing 2:35 ratio shots.

Are any of these things possible? The Red camera is just way too expensive, and modifying an HVX200 seems a bit scary (especially at the rate this technology is advancing!). Hell, by the time the modified HVX arrives, an HV30 could come out that is even MORE amazing.

According to the HV10 specs, it records directly in 1920 x 1080 when the HD/DV wide mode is selected. The 1440 x 1080 format is in normal mode.

- Tape Recording: DV (normal) mode: Approx 1.55 megapixels (1440 x 1080), HD/DV (wide) mode: Approx 2.07 megapixels (1920 x 1080)

Those are the sensor pixel numbers, used sensor pixels when recording HDV and DV 16x9 is 1920x1080, and for standard DV it uses 1440x1080 pixels, but records it to tape as 1440x1080 and 720x576 (PAL).

480 pixels is not going to make THAT big of an impact on screen, especially since you're still get 1080 horizontal pixels.

I stand corrected, the HV10 does record in 1440 x 1080 as explained by a note in the specs:

- The CMOS sensor in the HV10 is a 1/2.7 inch 2.96 megapixel sensor with true 1920 x 1080 HD sensing capability for 1080i HDV format video**.

**1080i HDV format video is an industry ratified MPEG2 video encoding standard with an interlaced resolution of 1440 horizontal anamorphic pixels by 1080 vertical pixels.

Whoops, then there goes the entire HDCAM product line, the single most widely accepted format for HD broadcast masters in the world today.

isn't that for STILLs to miniSD card?
All HDV tape recordings are 1440x1080 by spec. Non-tape formats (some HDD recorders) go to 1920.
