I'm playing around with lens vignette in my timelapse.

I wanted to start with none, and then have it gradually darken to a closed in "vignetted" look.
I tried it once and it didn't work. My keyframes had the vignette flash into place, but there was no gradual change.

I noticed in LRTL, that there is no field for "lens correction" or "vignette" in particular. -> is there a limit to what is written into the xmp file and there a limit to things that can be used in LRTL?

Ben, currently only the amount of the vignette is supported, the lens corrections are fully supported.
You can see all supported parameters if you remove the check at "hide unchanged properties".

I can add the missing parameters for vignette in the next version.

BINGO. Thanks!
