Good to get te comparisons up Joe. Does take time and effort, maybe get some more time with A1 before you do comparisons again. Also please tr and get optimal focus.

I hear ya ... when I put the shutter speed at 30 on my FX1, it really boosts the lowlight performance, makes it about equivalent with the PD150, but unless the subject is stationary, you get a lot of stuttery motion ... I'd imagine the same thing will happen with the Canon A1 ...

There is resolution loss on some SD cameras but my guess is that it would be very little on this camera. In fact, the posts shot at a 1/24 shutter at the 24f mode look nice and crisp. As noted above, anytime you shoot at a slower shutter speed, that's going to give you a slower shutter effect, which sometimes is a desireable effect. You really can't use shutter speed for exposure control in video unless nothing's moving much.

I too am very surprised to see the HVX's resolution that much softer and more blurred than the A1! I would have thought the HVX would be stellar compared to the A1, Sony's Z1 and other cameras in that class - I'd expect the HVX to be in a class above.

Hmm.. I didn't expect that low image - and I'm not referring to low light here.

I mean, isn't the A1 shooting at 24F going to experience a drop in resolution than what it could achieve? That A1's footage looked *really* good, better than other HD cams I've tested. But I was expecting the HVX to be sharper than the Z1U, but it didn't look that way

That's the first thing I noticed, aside from the great low light of the A1. I noticed that my dreams of the HVX are not so dreamy after all.

Hey, all the more power to the A1! Hurrah!

The HVX doesn't have the resolution of the A1 or the Sony Z1 either. They are all 1/3" chip cameras, so they're more alike than different, but higher resolution is a good thing. The best thing about the HVX is that you can do variable frame rate and therefor get good slomo. It's a very cool camera...but I bought an A1 instead.

Thanks, I enjoy watching the video a lot. Great job.

Variable frame rate can be achieved with any camera in editing. Shoot interlaced with a shutter speed of 100 or 120 depending on whether you're using PAL or NTSC and lower the playback rate when editng. Say if the playback rate's 0.5, that would equal 50 or 60fps and your editing software should interpolate the fileds so each becomes it's own frame. Well, at least Vegas works this way. Of course some vertical resolution may be lost, but still, I doubt end quality would be any worse than that of the HVX.

At the first clip is,I see clear that the HVX have more depth in the
colours and because of this depth also more depth in the picture.
Is this a question outher setting in gain of the A1 and the result will be the near the same as the HVX ??
