The new Rotobrush in AE CS5 is one of the best and most intelligent tools I have seen used. I just cant wait for AE to have the mercury engine support, because a 4 second 2k clip in 32 bit color-space took 4hrs to render. There were a pile of effects applied to the Roto image. And Color finesse is Amazingly stable, it actually useable. One day someone will realize howmuch money there is to be made in a render only board like the Final effects Blue Ice cards for AE from back in the day.
 
Look forward to trying the new rotobrush. I currently use Shake for all my clone brush/roto brush needs. Commotion used to do the best job of this... way back when. It's pretty amazing that such a useful tool has been missing for years from software that hasn't been EOL'd.

I used to use the Ice boards myself. At times they were a life savor to push through difficult renders (blurs, keys, etc...). We had plenty of issues with them talking to AE consistently... back when AE was a buggy mess. The idea is nice but they seemed to have a limited life span of usefulness too, before processors caught up to them. It was also true at the time that certain plugin's would work with them and others would not. That can be a lot to balance in a project or system.

The solution will be in better GPU systems that are being engineered to carry the load over what the CPU is doing.

Shashbugu, I wonder if the card in this link:
http://www.tomshardware.com/reviews/leadtek-winfast-pxvc1100,2523.html
wouldn't do as a render only card. I've been waiting for confirmation that Adobe products will utilize it's CUDA abilities. Not a bad card for the price.

Edit: Can't find where the render card itself utilizes CUDA, only the bundled software makes mention that it (TMPGEnc 4.0 Xpress) uses CUDA. Sorry for the initial misinformation.

I wish it all goes CUDA and renders cards turns to be Geforce/Quadro in SLI configuration and Tesla cards.. so as much you put CUDA cards as much you get faster rendering..
now a days nVidia is killing Moore's law and putting their own.. their concept is based on the parallel computing that everybody thought it will be the future..
 
There are many Render only boards out there. Quite a few actually. And AE has a built in node base render farm system. Frankly speaking its not a smart investment if future AE playback and effects are parallel programed like the Mecury/cuda playback combo. For the price of a render farm you might as well invest in a Nuke or Smoke system.
 
The Rotobrush tool works exceptionally well with Red footage. you do have to break the clip into segments based on action in the sequence. thats the fastest way to use it and render. And color finesse is incredibly stable.

What do you mean, back when? Only somewhat joking.

But on topic, I tried the roto brush on a challenging shot (not anything crazy, but there was a bit of noise and motion blur). Waste-o-time.

Tried it on some easy shots. Waste-o-time.

Looking at the demo, it seems like it would only work on shots with a heavy backlight...

Its not a one click solution. All video has noise. Thats why the rotobrush has clean up sliders for noise and chatter. I have not seen one good demo of the rotobrush, but right now we use it for a lot of visual corrections removals and compositing. It is truly amazing. It makes life a lot easier. There are endless ways of using this tool.
 
I second this. It's not a chromakey, but close to magic once you dive deep enough into it.
 
I'd love to see a decent demo of the roto brush on some real world footage. My first experiences were less than encouraging I have to say, especially as the first tests were with what I thought was going to be pretty friendly footage.
