hi

i am using this method
http://library.creativecow.net/articles/mcauliffe_kevin/motion_key/video-tu...

to remove a figure from my shot

everthing works fine but when i play back the shot with the figure removed i can see a faint vertical band moving acros the screen where the figure was

does anyone know why this could be

thanks

There could be several reasons for this, such as:

• mask not big enough to cover the moving object in every frame
• replacement range not long enough / too long
• feathering too big
• luma comp set too low / too high

I think your options are either:

• adjust the aforementioned settings until you achieve the desired result

or:

• render the result that you have an re-run the motion key on the rendered result to eliminate the vertical image artifacts.

I hope this helps.

Peter.
