Crop vs garbage matte
on Nov 15, 2010 at 5:36:36 pm

Could anyone please help me out and give me some guidelines on when to use the "Crop" and when to use the "Garbage Matte" filter, please?
When is it advantageous to use one and not the other?

If more details are wanted, I'm more than happy to supply them.

Regards,

Lawrence

Hi Lawrence,
First sight, he only difference is that with the "Garbage mate" you have more flexibility to build a shape.
Another difference is that with the "Garbage mate" you have more precision. The "Garbage mate" works with pixels, while the "Crop" function works by percents.
And another difference that can be very important when compositing, is the place in the pipeline.
A "Garbage mate" would be processed before than a Crop. In FC, effects are processed before "Motion Effects" (center, crop, distort..).
If you can do it with cropping, avoid the "Garbage mate".

Rafael,

Sound advice. Many thanks. My quirk is that I'm trying to reproduce a jumpbox in a web page and the crop feature will not allow me to keep the dialog box AND have the jump box drop down...sounds like a case for garbage mattes!

:)

Lawrence
