I’m posting this here so I remember it for the future:

Today Rohan shared with us a tip for whittling down raw footage into something usable:

• Dump all of your footage in the timeline, and watch through it once
• Every time you come across something that definitely won’t be needed in the final version (your questions, irrelevant answers, coughs, etc.), place a cut before and a cut after it
• Leave the unneeded sections on the first video track, and drag everything else up onto track two as you go
• After doing this for the entire video, drag to select all of the video on track two (that is, the “longlist” of usable material) and move it to a new timeline
• Repeat the same process on the new timeline

This way, you progressively cut down your footage to only what you can use within two full viewings. I think this will save me a lot of time.
