To remove Vignetting, or not?

I use a wide-angle lens on my Canon HV30. When I zoom all the way out, I get some vignetting in the bottom right corner of the image. I have a couple hours of vacation footage I'm editing, and this occurs several times. I can easily use the pan and crop to zoom in a bit and eliminate the vignetting, but then I decrease the resolution of the beautiful HD image I'm so carefully trying to preserve, correct? Would you pan and crop...or just live with it?

Any of those shots need stabilization?

malowz,

How would you crop the image?

That should take very little cropping to eliminate IMHO. Just due a pan/crop at the end of the full zooms in the reverse direction.

You can try to compensate the black edges simly by using Soft Contrast's vignette feature, but with negative values (so the vignette would be white instead). Then, by trial & error you should be able to find the sweet spot. If you need fine tuning, Magic Bullet Looks should do the job (again, by using minus values). Hope this helps.

I agree. Use pan/crop where the vignette bothers you. Your HD image can stand a little cropping without much degradation. YOu need not stay cropped but can use keyframes to zoom in and out.

I use a wide angle too on my vacation video. It really makes a difference. I notice the vignette mostly when there is rapid camera movement. This lends itself to quick in and out pan/crop zooms without being noticed.

i would brighten up the edges to make the image even.

there are numbers of ways to do this.
