I was wondering how i can generate a video preview thumbnail for a video. Im guessing it should be done with FFMPEG if im not mistaken? So what i want is kinda like youtube so i dont want the preview to be made from images i want it to be a video preview. So for example lets say i have a movie and i want to generate 3 seconds at beginning and 3 seconds in the middle of the video and 3 seconds almost at the end of the video and then merge it into 1 preview video. How can this be done?
I hope that i have explained everything properly
