HV20 - is anamorphic possible?

Hello all,

Sorry for the re-post, but I wanted to get this question "visible".

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 incredible.

You could use a 16:9 adapter in front of the HV20 lens. That would give you approximately 2:35 aspect.

As for the Lomo with 35mm adapter, you would get wider than 2:35, because of the 2x anamorphic + the 16:9 aspect.

The sensor on the hv20 is 1920x1080 native. It's unclear if the HDMI outputs 1440 or the full 1920 though. (Can anybody here find out about this?)

The problem there is no way to display this image on anything but a computer, as the image is doubly "squeezed." 2.35:1 DVD's are 16:9 and matted, not 2.35:1 native, as DVD's have no way to handle that information.

Some people use anamorphic lenses on their projectors. Would this help display it properly?

Lots of people use HTPC's as well.

The advantage to this if you were framing for widescreen is that you are using the entire chip to capture a 2.35 image rather than letterboxing the 1.78 chip. Presumably in your NLE you would ultimately output it as an anamorphic 16:9 clip for DVD etc., but you would be working with more information to begin with which is always useful.

As Mike points out, using an anamorphic lens on a 16:9 projector will deliver an improved 2.35 image than the letterboxed alternative.

I believe the squeezing of 1920 down to 1440 is a process of the HDV codec. I would think the uncompressed feed should be the full 1920.

I also would be very interested to know if the full 4:3 chip could be accessed.
