  • Creating a timelapse from a directory of jpgs

    26 juillet 2020, par Casey Davis

    I'm using this code to create a timelapse from a directory of images. My directory has about 1600 jpgs in it that all start with the date in this format 2020-03-01-time.jpg, 2020-03-02-time-name.jpg, etc. Sorting alphabetically works just fine. It runs, but it seems to only get through a few hundred photos and makes a 3 second long mp4. I'm not sure what I'm doing wrong.

    


    I'm not opposed to moving to python or anything else. Eventually I'll need to pass some parameters in here and I'll attempt to automate it and ftp the output to a webserver.

    


    Here is the command :

    


    ffmpeg -r 24 -pattern_type glob -i '*.jpg' -s hd1080 -vcodec libx264 timelapse.mp4


    


    Here is the output :

  • ffmpeg Videos Won't Play Centos

    17 mai 2016, par Dan

    My exported videos from ffmpeg won’t play on anything. I am trying to create a simple slideshow type video from images. It will create the video, the video will add 5 seconds in duration for each image I add but it just doesn’t play on anything. It’s driving me crazy.
