但MASK不是可以TRACK的嗎??
Yes, depends on what program you're using, you can apply tracked data to the whole mask or just point of the mask.
haze 寫:另外,如CGV HEADLINE所說的加龍卷風又是如果做的呢?
是3D制作還是有另外的方法呢?
I haven't read the headline, but I would say it depends on what your production needs, but both 3d and 2.5d comp can do that.
The key thing that a compositor needs is a good eye, good art scene... good compositor should be able to create and put together element to produce a quality shot, that includes techiques like rotoscope, key, track, color adjust, knowledge of particles system, etc...
check the following links if you want to know more about what compositor do.
