how you managed to time this single uncut monologue and casually describe the exact length of the video is a subtle nod to the pre production behind these videos. Great job as always Tom and team!,(reply>), @Brodie Bligh  Yes but it would need to include the length of the intro which was a separate shot.  Not that it is hard to do," but a simple timer from the beginning starting at <a href=""https://www.youtube.com/watch?v=iZnLZFRylbs&amp;t=0m00s"">0:00</a>  would not work with a separate intro at the beginning.",(reply>), I'd guess a timer to read from and adding whatever from an estimate or prior take.,(reply>), Guys i think there was just a clock behind the camera,(reply>), Thanks for pointing that out. I had to replay and understand what was going on to even appreciate it.  Then I figured it out. It was done by 1) a good estimation of the script length with a few practice runs. 2) Leaving one cut at the intro to slide the body of the video up or down the timeline to match the timecode.,(reply>), @Martin Mojžíšek I don't think there was much edits.  They just had an extra long ending screen.
