View Full Version : Lumakey to get alpha doing garbage roto

12 December 2008, 08:43 AM
Hi need some help in luma key ,

i have done a garbage roto around ear and i want to do luma key and generate alpha channel and add it to rest of roto, can you guys show me what best way should i choose to do this, i want to avoid roto coz when i am doing roto the guys movement is so random in shot that i end up with swiming on edges and moreover the shot is 2K so swimming is easily becomes visible... :hmm:

Looks like you are using Shake:

lumakey=>inside+rotoshape=>over rest of key.

if you want to avoid swimming why don't attach the rotoshape to a tracker?
