Feature Request: Add option to save split videos

[rfboykin]

Add option for users to save videos after they've been split
If using .txt file input, can be done with flag on specific videos
ex: http://youtube.com/abcd123 s

A purpose of this is to edit the video and then use it in the hour.

This additionally requires us to be able to inject videos from host machines into the code using a filepath (can work with relative or absolute). This would need to be done in conjunction with the dynamic videos and requires a position.
