Keyer

Want to replace the phones screen when making videos? Use Keyer

Very simple app that puts a solid colored background on your phones screen, as well as adding tracker markers so you can easily replace what is on the screen in post-production when you are making videos and advertising.

A very common thing to do these days when creating promotional videos and advertising is to have someone interact with a phone. Sometimes you don't have a specific app created for the shoot so you would want to replace the phones screen later on in post-production.

This app makes this process simpler by adding a solid colored background (e.g. a greenscreen or a bluescreen) as well as tracker markers in the corners of the screen. There are 10 different tracker markers and six different background colors. Tracker markers can also be scaled up and down, or turned off, depending on what you want/need.

PS: Click the top left corner to bring up the settings page. This page can be a bit tricky to open if you have set the tracker marker size very small. Keep trying and it will open.
