After many years of experience we see that people can record an average of 5 to 8 videos in 1 hour and 30 minutes. That is why we work in blocks of 2h (including getting the lights and camera positioned). Typical presenters, (people that do e.g. a lot of keynotes) are better trained and can probably do more. The current record at Chaomatic is 28 videos in 1 hour. (A record proudly owned by our CEO.) Feel free to beat this! But we do not expect you to do this. It is normal after recording a lot of videos you’ll feel very tired as this is a new skill you’re learning.
