  • How to deal with a cameraman reflected in a mirror

    Posted by Calvin Osborne on November 17, 2011 at 12:36 pm

    Hello,

    I am just learning After Effects and was wondering if anyone had a suggestion/technique they would mind sharing for this situation. I am trying to edit some footage that, unfortunately, was shot in a room with a couple of mirrors, and the cameraman keeps getting reflected, on and off, in the mirrors as he is moving around the room. It is only for a few seconds each time, but impossible to deal with by cropping the video. Any suggestions would be appreciated.

    Two steps to fix this, one pretty easy, the other pretty complicated:

    Step 1. Create a matte that covers the unwanted reflections. You can do this by making a solid, then applying and animating a mask for those areas. You can also do this with MochaAE, which is generally faster and more accurate, but takes a little longer to figure out the first time.

    Step 2. Create something to put in place of the matte. If there isn’t a lot of detail (blasted-out whiteness, e.g.) this is pretty simple. If you have a lot of detail then you will probably need to create a matte in photoshop that covers the trouble area. If the camera is moving you’ll need to match the movement inside the mirror which means you’ll need to match the movement inside the mirror. You can eyeball this, but it would be better to track it with MochaAE, if you can find enough in that mirror to grab onto.
