Bake-in SRT Captions into Videos Using ffmpeg

For STEAM Powered Facebook videos and YouTube allow you to attach an SRT file for captions. However, Twitter and Instagram do not and captions need to be baked-in.

Use this bash script create new videos with the SRT captions baked-in. The script needs to be run in the directory that contains video files with their corresponding SRT files (with the .en_US language suffix). New videos with the captions baked-in will be created in the same directory.
