Can’t controll mask points

[Anonymous]

Hi,

I have a problem in Combustion 4, It’s no problem to make a mask at frame 0 and then again at frame 100, and it also goes well to adjust the mask at frame 50, but if I later gonna finetune mask point, the mouse cursor goes away from the mask point.

Please se flash video for example. Am I doing something wrong, or is it a bug? http://www.mypencase.com/comb/test.htm

hi greyj,

you have to select all keyframes and set the interpolation mode from “bezier” to “liniear”.
that should do the trick.

hey greyj,

make sure you did not mixed different frame rates, like 23,97 and 24, or something like this.
this behaviour is typical for mismatched frame rates and yields sooner or later to a corrupt mask. better match the frame rates asap before your mask goes haywire

best,

you can also use the arrow keys to nudge/keyframe the selected control points while doign roto. nice.

Hi,

Thanks everyone, it was a framerate problem. I find it hard to make a mask on people in motion, I can’t get it smooth. Any tips n’ tricks to share? Is it better to make a mask first on the head, then the arm, insted of taking the hole body? Guess there isn’t someting called “automasking”?
