a little utility for editing sections of video and audio together

this node app shells out to ffmpeg and ffmpeg-concat. you'll need to have both available on your path

brew install ffmpeg
npm install -g ffmpeg-concat

this is a bit janky, as i threw this together quickly to help a friend :). it's only been used once at this point. i'll come back to make edits should i find it more reusable in the future.

place the file you are attempting to edit into the root of the project and name it original.mp4

then edit src/input.js with the timestamps you want your final video to be.

the format for an item in the inputs array is:

[start-time, end-time, duration]

there is a potential bug here in that the frames created in src/create_frames uses the end time, where src/create_slice uses the duration. this didn't prove to be an issue on the initial usage for this, but beware

ffmpeg-concat doesn't currently concat all the audio so we're using some thinking from this github issue to make the audio sections work.
