Hello,

In effects where the length of the effect passes over the part of the image that is the black bar (i.e the black bar you see at the top and bottom of a widescreen image); the effect passes over that area and for me that is a strict no-no.

Is there are way I can set an area of the image (or canvass) to never show anything but the black in those areas?

You should really work with the footage in a project set to its actual resolution. Don't letterbox the footage until the very last render of the entire project. If for some reason you need to have it letterboxed while you are working on it, you can use masks to block those areas out so the effects don't overlap onto them.

ok 2 square masks to line up, but does it line up exactly or is there still some slight hangover?

Masks covering "widescreen bars" are tricking because of interlacing. On most projects you will find that every other frame shows a little bit of the effect over the black bar, then a bit of the effect cut off. As Axeman said: Use the correct resolution for your project.

if its in 4:3 it doesn't need letterboxed. Letterboxing is for viewing widescreen footage on a 4:3 screen. if its already 4:3, you don't need to letterbox.

What program are you using for editing?

The best thing to do would be to shoot the widescreen footage in 16:9 anamorphic, which will probably yield better results and also avoid any letterbox issues.

Or, you could take two black images and just strech them over the bars, and keep them at the highest layers.
