Would like to know if Corona SDK can recording a piece of animation played on the phone, and output as a .mp4 format video for both iOS and Android devices?
Thanks for you answering. 
Hi @sinergy.tw,
At this time, Corona Starter/Pro can’t record video; only record audio or capture normal images (screens, photos). This is a potential feature down the road, but it’s not currently possible. Sorry for the inconvenience.
Sincerely,
Brent Sorrentino
