Movie slates are used to display useful info to the video editor and allow the editor to sync audio and video. This is a SUPER simple movie slate app. It's not fancy, but it does the job. Just type in the information, show it to the camera and hit "clap". A red flash will appear and a clap sound will play. From there you should be able to sync your audio and video in post just as you would with any other movie slate. If you have any ideas for improvements please let me know via a 5 star review or via email mail@brendenvogt.com Enjoy
