My image has a handful of configurable options, if time permits I would love to add more.
I do have my videos templated out a bit, I have a border separating the date and key from the actual video. This originates from another script I have which creates quad video output so you can compare 4 git repos at once in the same video. I used some sed hackery and named pipes to keep everything in sync. I hope to be adding this script to the container soon as well. Let me know what you think!
