Haven't seen many Mobile chats soon.. So i decided to tell you about this. Its an app named SloPro. You take a video, and it automatically slows it down.. You can edit the video to be fast, slower, slow, faster, fastest, 500 fps, 1000 fps, and more... Its really awesome and i Suggest checking it out

Isn't it the same as slowing playback to .10x or .05?
Or it really set the shutter to that speed?

Have been using it for a long time. You take a video and you pick the speed for the video to be. There are some minor editing though.
