6.3 Geo Face Selection

Anyone know what are the uses for Face selection?

I tried the snapping functions and it asks for points. I checked the manual and it only says how to activate it and make selections.

directional edge detection

Extremely new to nuke. This weekend I went through a bunch of tutorials. I’m getting the hang of it. I’m trying to fake a directional edge light on footage that was shot on green screen.

I would like to use my key/alpha to pull a directional edge detection. I normally would use sapphire edge detect in flame. It has a directional parameter built in. Is there a way to do this in Nuke without 3rd party plugins? I’m aware I can mask it but looking for a quick solution.

Much appreciated!

6.3 slower than 6.2?

Is anyone else noticing 6.3 refreshing the viewer slower and freezing a bit more than 6.2? I’m working on a stereo project, both views update so slow compared to 6.2, it’s really unusable. I’m running win7 x64.

I guess I need to read up a bit more on caching and memory optimization. Does anyone have any tips on how to set that up?

keyframes

you all have been very helpful in replying to other questions, thank you all very much!!

the problem i am having now is that i have a clip thats 389 frames long with a tracking node applied to it. from fram 1 to 241, i have an image tracking on top of my footage, but the actor walks across the screen (and subsequently over my tracked image, which ends up on top of the actor) for about 10 frames. so i need to remove the image for about 10 frames while he walks in front of the object being covered by the tracking image, and then i need that tracked image to return after the actor has finished walking in front of it.

i have set the frame range of the tracked image for 1 – 241, but i don’t see how i would be able to have it re enabled after that. furthermore, the only options i have after frame 241 are to bounce, loop, hold or turn to black. i’d LOVE an option to "disappear". 🙂

what are my options? this node based editing is all very new to me. if i were using a linear editing program, i’d simply remove that jpeg from the timeline for those frames and have it return when i needed it.
