Same day edit - it's possible
Last month I received an enquiry which challenged my speed at work.
My new client (ARBEIT UND LEBEN Berlin-Brandenburg) asked me to shoot an event and straight after that, edit a 3 minutes highlight film including interviews and music, which would be presented on a big screen at the end of the day to all the participants of the event. I had 90 minutes in total for postproduction. Before the event and made sure I had a quiet room to sit and work. We had also agreed on the music before the event.
Have a look at the result! :)
