As someone who is also learning this stuff, I can totally see how that would be useful. Unfortunately this is currently not a feature in the video player. I have reached out to the developers to see if this is something we can implement in the future. Thank you for reaching out!
In the mean time, is there a specific video or specific sections of some videos you would like looped? I can export and upload that for you, custom! I will just make a really long video of a section looped for you.
However, we are in Spain collecting and creating more new content at the moment, until the 21st of August. I will be back at my desk on the 23rd and able to make looped videos for you. Please let me know which ones and where you need them looped!!
