Hyper 8 now provides interactive feedback on encoding progress and estimated time remaining \o/ (went from exploratory coding for getting the data from the ffmpeg child process all the way to a polished UI integration today, yay!). I also learnt that ffmpeg offers a -progress option for sending progress data to an arbitrary url, which is pretty rad (although I didn't use that in the end). <25 days to beta! ʕ◜0ᴥ0ʔ
