XL1 or other frame mode camas versus PDX10 at 30 fps? at DVinfo.net

Ok here is my crazy question of the day:

Using a PDX10, which is a native 16:9 little camera, I can get really good 'anamorphic' DV. Now even though this camera doesn't have real proscan, you can get poor man's (that's me allright) proscan by setting the shutter to 30 fps, but the result is line doubling, the usual Sony kind. However, since the CCD is still working in an oversampled 16:9 mode... it might end up being better than the XL1's proscan with it's non-native 16:9. Anybody out there have both cams to test? Leaving away things like optics, low light sensitivity and 4:3 performance, which would be the better cam at 30 fps? Of course us PDX10 users would like to think it's better... and probably Canon fans will say the XL1 will do a better job... any ideas?

I like both cameras, but in my opinion, regardless the mode the PDX10 will have better resolution, even more so in 16:9. It is possible that you will get some blurry motion with the 1/30 shutter, but resolution-wise the PDX10 is going to win hands down.

Even with the Sony line doubling?

I beleive so. I think the line doubling you are talking about is the fact that the camera records in interlaced mode at 60 fields per second, but you are using a 1/30 shutter effectively recording a single image per two fields, or 30 images per second(thus the 30fps 'approximation'). Not sure how this would have any negative effect on resolution, i don't see why it should. The only difference here is that the odd and even lines will be from the same image, while if you use a 1/60 shutter or less the lines will be from different images.
