Live: Deep dive into Rao's Filter 2.1 (using Square Mile's Filter Roast)

This is an old video about dialing in coffee on our espresso machines. You can find the DE1XL here.


Here is the episode we just filmed, covering Filter 2.1:

We tried a lot of new things with today's shooting:

  • installed a metal ceiling rack
  • moved from a 4 channel video mixer to an 8 channel one
  • down-facing camera installed, looks onto the cart table top
  • 2nd camera on Paul
  • two mics hung from the ceiling, above our heads
  • two lights hung from the ceiling on the sides
  • video titling software showing the current recipe and grind settings, changing in real time
  • beans weighed ahead of time
  • sound dampening curtain hung in the corner
  • I waved my arms and torso less than previously, toning down the mania and staying in frame more
  • HDMI amplifying repeaters installed, so we could site the video editing desk from from the cameras using long HDMI cables, and put the cameras where we wanted them
  • Balanced XLR sound output used (special cable arrived) solving 50hz audio buzz problem
  • Consistent picture-in-picture showing the tablet screen during extraction
  • Actually read the live questions and got to answer them on-air

  • What we got wrong:

  • Niche was powered off (again!) at the start \
  • Main camera overheated and shut down several times, until Harris figured out how to override the shutdown-on-overheat behavior
  • Paul-camera tended to auto-focus to the background until Harris changed it to manual focus

  • Still to do:

  • figure out how to use audio compression, limiting, to tamp down on audio volume when we get too loud
  • flush text left, when right-aligning the grind settings
  • record the session with all cameras, to a hard disk, so we can improve the edit afterwards
  • a camera on the extraction itself, showing the bottom of the portafilter, shot liquid, cup and scale
  • a camera on me too
  • install air conditioning, so the camera doesn't overheat
  • install sound dampening material on the ceiling
  • install vertical wood slats sound dampening background that also looks nice, behind us
  • make the sound better when Paul and I face away from the camera

  • Here are pictures of the video studio as it was today.
