Takeaways: 1) Making videos is in some way harder than doing a talk live. 2) Screen Flow is awesome, but could be improved with more video editing capabilities, apparently you can't "cut" the video. 3) The problem is to upload files when they are big and you have normal ADSL connection :-) But it feels good to be able to send the video talks a few days in advance, so the conf organizers will be able to perform editing, filter audio if needed, whatever.
