Dealing with sheen and lighting changes

I have a tricky shot I need some tips on. I need a perspective track on a door that is swinging. The issues are the actor covers the door for periods of time and the color of the door changes because it’s picking up highlights as it swings. You can see the 3 different tracking areas I’ve tried to use and also the holdout mattes for the guy. I’m still getting unwanted drift and I think it’s mostly because the color of the door changes a lot from the exterior light. I’m fairly experienced with Mocha, but could use some tips from folks more seasoned than I. Thanks



Hi there,

So you can track just the top of the door and get the information for the whole door, that will give you best results while you avoid large areas of reflection and where the talent passes over the door. You can also cheat and grab the front edge of the door to give you some extra texture anchorage for mocha even though it’s technically not on the same plane you can probably get away with it.

Get the track as close as possible and then this looks like a job for manual track (for the occlusions and the drastic lighting shifts):
And adjust track for overall correction:

Try that, and if you have any questions, let me know and I will be happy to help you.


Thanks Mary, manual track is something I hadn’t tried yet. I’ll give it a whirl. I watched that video and you used a shot I sent you a couple of years ago from a Panasonic shoot. Lol.


How funny! Well, it’s still appropriate! :slight_smile:

I don’t know what rock I’ve been hiding under, but manual track just rocked my world. Wish I had looked into how to use that before now!

Happy to help! It’s not used nearly as often as you’d think, but it should be. It really helps those nitpicky keyframes between occlusions.
