Article: It is easiest to edit a documentary that has a lot of coverage. Split footage up into folders, e.g. "b" roll, interview, etc. Watch all the footage, listing highlights, overall action in the scene, and anything else that you feel is important. Write down what happens and what you think is appropriate.  This is a huge job, so don't underestimate how long it will take. Make sure to break the core into manageable chunks. This is where you capture the gust of what the interviewee says, not the entire dialog. Do this by breaking down the interview into half minute segments. Work out where these should go in the interview at the end. This will be useful when it comes to the paper edit. Editing a documentary can put a lot of strain on, especially if you are working in HD. Do an offline edit where you convert to standard definition. When you have locked off (finished) the edit, re-import HD footage. Create a two column table in word with one column for video and the other for audio. Each row is a different scene. Put all clips and interviews in order and play around until you are happy with it. You can edit after that. This is helping you create a blueprint for your edit.
