So does anyone have an idea or suggestion on how this can be accomplished with relative ease? I can probably do it by calculating the length through code and running a command to extract each individual frame from the video that's needed then generate a gif from the images but I'd like to be able to do it all with just one command.

Video length / 10 (length of desired animated gif) = interval to use between frames but I don't know how I can use that data to accomplish my problem. Where you end up with an animated gif that's 10 seconds long showing a preview of the entire video no matter the length of it. Video position - gif frame/per second video position - gif frame/per secondģ second interval between frames 10.5 second interval between frames I'm trying to do something that spreads out the frame gap to cover the whole video length but create an animated gift that's no more then 10 seconds long.įor example say I have a video that's 30 seconds I want the gif to be 10 seconds long but cover frames of the entire 30 seconds so it might start at frame 3 or 3 seconds in and create a frame in the gif, then at 6 seconds in the video create another frame, then 9 seconds in another, and so forth where the final outcome is example video 30 seconds long example video 1 minute 45 second long Which works for creating a scaled animated gif with a fixed width of 150px at a rate of 1 frame per second but its only an animation of the first 10 seconds of the video. The code I'm working with now isįfmpeg -i test.mp4 -vf scale=150:-1 -t 10 -r 1 test.gif The problem now is I want to show the user a short scaled preview (animated gif) of the video before they click to play it. A brief overview of what I'm trying to accomplish I have a site that will accept video uploads, uploads get converted into the mp4 format to be uniformed and playable on the web using one of the many available players.
