Add Postprocessing Guide Section To Scale AV Manual For Using Transcriptions

[DavidMWu]

What I'm showing is more of a proof of concept for introducing video transcripts into the workflow, so I expect this to become outdated quickly.

1. Open corresponding room transcript.
2. Search transcript for a introduction or something indicating the talk is starting and mark the start timestamp.
3. Verify the start timestamp and talk title is correct in the embedded YouTube video.
4. Search for the expected end timestamp by calculating how long the talk is (usually 1 hour), and do ctrl+f for "thank" around the expected time the talk should end. Save the end timestamp when you find it.
5. Verify the end timestamp is correct in the embedded YouTube video.
6. Skim through from start to end of the video and note down abnormalities and their timestamps. i.e. No audio, camera out of shot, no slides.
