Applying lens distortion to 2D trackpoints in Nuke?

Hi there,

Just wondering if anyone has had any experience with applying lens distortion to actual trackpoints in nuke? Basically, we have shots that need tracking, but we don’t have lens grids shot yet, so I was hoping to track the plates without undistorting them and then, once we have grids shot, undistort both the plates and the tracks….

Any help would be appreciated….

Cheers

Mac Graphics Card Upgrade Question

I have a MacPro 3,1 with a geforce 8800GT in it…the card is starting to show its age. The only upgrade cards Apple has available is the GT120 which is worse than what I have, the ATI 5770 which is a lot better, and the ATI 5870 which is a LOT LOT better.

Anyone have any of these cards that could make an informed suggestion…or maybe even someone that knows of a PC card that works amazingly in a Mac? I have read that the ATI 6970 will run on Bootcamp but not on Mac side….so that would be great to have the added support in Windows…but I really want the power Mac side too…but the 5870 is a 2 year old card and at this point pretty outdated.

Also if anyone knows of a way to force Mac to work with a better card, like the 6970 or preferably an Nvidia card I am all ears!

alpha merge problem

Hi everybody,

I’m pretty new to node compositing, I was trying to composite some fumefx with debris, rendering it separated from smoke.
I thought that using a matte material on debris (that rotates around the fume) was the good way to do it, but when I started merging channels in fusion I had this problem:

and this is the correct alpha from the beauty pass, with debris and fume in the same render:

I hope someone can help me with this problem 🙂

Thank you in advance,

Matteo
