  • Quick roast bean colour change video

    Just playing with a GoPro to see the beans colour changing during a roast just for interest.

    What was the 'real time' duration 'ts'?

      I took this a few months back, it would have been about 20 minutes, I took this at 20X speed.

      Sorry Mal, I ment 10X.

    Good work. Does the GoPro have the ability to include a timer? I'm guessing though that at 20x speed it wouldn't be very readable.

      I actually made a mistake, it was shot at 10X not 20X.
      It does have a time scale on it for the length of the video. 6 seconds of video is 1 minute of real time.

      Yes I saw the progress bar at the bottom but a 2 min video shot at 20x equated to a 40 minute roast. I thought some sort of fancy compression might have been used
      Makes sense at 10x

    Great video. I like the magician trick at the end where the beans disappear in cloud of smoke

    Good looking roast too!

      Very cool. Have been reading up on roasting earlier today and then lo and behold a video which shows a lot of concepts in action!

        Vey nice.
        I did a very similar time lapse on my Android phone at the end of 2020.
        Must be a Hottop thing.

          Here are another two videos, both done at 5x speed.
          1st is an Ethiopian Ardi Late Pick filter roast. (9 minute roast, 1.54 minute video) Fantastic V60 coffee/roast.
