Newbie Things To Remember When Rotoing in Nuke

[Benoit]

lol shake is even worse. use Mocha or silhouette if you can get your hands on them. at the very least you can track in mocha then export your tracks to corner pin your beziers in nuke. itll cut your roto time in half.

I had to roto in After Effects, Combustion, Shake and Nuke, and I have to say that to me Nuke (especially with the RotoPaint) is the easiest one once you get used to it, because of all the additional tools you get like you all mentioned (motion blur, transform of selections...).

I would second the "Another way to think about it is to think like an animator would.": feel the movement and do your roto according to it (I had to roto a piano in a travelling & panning shot and could not get it right until I felt the movement correctly).

Roto only the area you want to hold out (or maybe a little extra for some buffer). In most cases you wont need to roto the entire object/person.

When 3d roto projections are out of question (like organic shapes), I do prefer use combustion for paint/roto. Easier to track spline points, more granular control of every point on the mask. I try to avoid keyframe every 2 or 3 frames (unless when I'm tired and lazy!!). In combustion it's easy keyframe single points (I dont know how to do that easily in Nuke) and this helps a looottt.

I like mocha for roto and their planar tracker, but again, combustion dope sheet it's easier, more complete and less buggy.

My last hope is Silhouette, I'll try it next week, but roto is a painful job, every tool at our disposal looks a little incomplete imho.

When rotoscoping things like hair/fur, do you do paint strokes, and mainly use spline rotos for the bigger areas? If so, do you do paint strokes for each frame?

I have a small doubt.. i am a beginner in roto..

2 important aspect for roto which i am not aware of is how to roto hair & how can i roto motion blur.. i am using nuke.. i will be great help if anyone can provide me some info on it or some link..

1. Study the footage-take notes (eg in frame X the leg changes direction
or it hides-maybe you need new shape if it hides for too long etc).
2. Track (2 point track)so to stabilize everything (maybe deinterlace first).
3. Use feather.
4. Remember: roto workflow is not standard depends on the kind of motion.
5. Do Roto in Nuke why not?
