Canon HF11 to replace HF20 with 24 Mbps

I think RT compression will always suffer the "one pass" syndrome. I feel its time RT encoders looked at wavelet compression instead of DCT, as this would have a very big impact on the quality and may negate many of the compression artifacts that we see today.

I know, I know before you say, RT wavelet compression is easy to say hard to do :D *goes diggin for some books on Matrix algebra and FPGA design*
 
Yeah, but when will they fix the rolling shutter issues? I'd use one of these in a heartbeat, but after my experience with
rolling shutter on the HV20 and HV30 I'll need to see a fix first.
 
Many people seem to be satisfied with the workarounds for the rolling shutter issue. Especially in a consumer cam.
 
Slow shutter (1/24 to 1/60, this is the biggest factor)
OIS always on. Please.
Avoid handheld. Tripod good.
If you can't, be steady and don't zoom.
Avoid moderate to fast pans unless you're tracking a moving subject tightly.

And finally, don't attempt to stabilize your footage with an certain after effects plugin that doesn't suppport rolling shutter camcorders. (that where much of the "jello" footage on youtube comes from, apparently!)

Which of the above guidelines are you currently not following?

Don't shoot like it's a Bourne film and you should be fine.

Precisely.

Ah, I see. Thanks for that. Most of those guidelines I'm following - most. Now, help me out if you could with your first point (slow shutter).
Do you mean don't shoot in that range? Or just be more careful in that range?

Edit: sorry for hijacking the thread...

One should always shoot in that range:
i.e. use the slowest shutter you can get away with.
A fast shutter exaggerates the rolling shutter artifacts.
 
Canon's site says it's going to be available in September. I'm actually very interested in this camera. If it doesn't have the rolling shutter issues then I'm picking one up for sure.

I have a hv20 right now and the only way to capture 1920x1080 is with a black magic pci card. I think that runs like $250. With this I can get 1920x1080 without any other hardware, right?
