HD1 vs TRV70, sample clips?

I know HD1 is single chip, so color won't be as good as 3 chips, but how it compares to TRV70? I think, color and low light is acceptable, if HD1 is at same level or slightly better, I will probably consider it over pdx10, which I am evaluating now.

BTW, is there any HD clips, full size, that I ca download? (outdoor), I have downloaded the "hotel room" clip, (quite good)but it's all in door lighted...

Thanks!

I think I didn't make my question clear. Let's say :
If one crops HD1/HD10 video to 720x480, is it on pal with TRV70 can do?

Love, why the intersest in comparing two completely different cams?

Don't you have a PDX10?

Do you really mean "cropping" the HD1's footage (i.e. discarding part of the frame), or do you mean "resizing" the whole frame down to 720x480 (as you would if you were making a DVD from the HD1?).

As it happens I've just bought both these cameras in the past week in anticipation of some fieldwork in Mongolia, and I will be interested to find out the answer to your question myself...give me a few days.

For producing mpeg2 for DVD I am anticipating the HD1 in HD mode will be better in terms of apparent resolution, given the greater number of pixels for the software mpeg compressor to work with. But in SD and DV mode it will be interesting to see.

He meant, if he was to shot a project with the JVC in widscreen, and in consideration of a possible 4:3 SD release, he might want to frame the subjects in an imaginary 4:3 box and then just simply crop it in post...... I don't think this workflow will give you any advantages over existing 1-CCD cams.

if you cropped the sides off a widescreen 1280 x 720 frame, wouldn't you still have a resolution of 960 x 720 in 4:3?
or am I missing something?

No... I'm saying crop it so only a NTSC sized frame remains. The whole point is to skip the resizing stage.

Respectfully, I really doubt he wants to do that. It would completely change the focal length of the shot, and why bother when the camera has a built-in 720x480 DV mode (that avoids the need for MPEG2 compression)?

In a dual format release situation, it makes total sense.

Um ... I wasn't meaning to get into anything on my very first post on this forum .....

Care to clarify, LoveMov? Are you wanting to compare the HD1 with the Sony's 16:9 or 4:3 performance (both of which are 720x480 pixels)? Are you interested in resizing the whole HD1 frame, or cropping parts off it?

I am actually talking about CROP.
The reason is that onc compares them fairly without resolution difference and resizing PQ degrading. Basically, the raw chip performance.
