F-Droid doc listing fastlane structure do mention video:
video.txt (URL to a video introducing the app)
Is this supported anywhere (f-droid web, mobile client) and what formats? Fastlane docs themselves are mentioning mp4 : capture_screenshots - fastlane docs
Thank you. So on desktop, this is not available at all. On the mobile client, there is a small link in the (overlooked) links section at the bottom. Given how much work it is to produce a good video, this is not very encouraging.
