• Ffmpeg generated movie (png -> mp4) has no video

  21 avril 2016, par ILiveForVR

  I have a whole bunch of png’s which I would like to convert into a mp4 video.
  I am using the following command to stich them together :
  ffmpeg -i _2016-04-20_14-51-00-500_%06d.png -pix_fmt yuv420p movie.mp4

  I am getting a file, which has a size so it isn’t empty. But when I play it in VLC or Quicktime it shows the time going by, but it has no video in it. Any idea what I’m doing wrong ?
  I also tried :

  ffmpeg -framerate 1/5 -i _2016-04-20_14-51-00-500_%06d.png -c:v libx264 -r 30 -pix_fmt yuv420p out.mp4

  and

  ffmpeg -r 45 -f image2 -s 1920x1080 -i _2016-04-20_14-51-00-500_%06d.png -vcodec libx264 -crf 25  -pix_fmt yuv420p test.mp4

  But still no video.
  This is the commandline output :

  >ffmpeg -i _2016-04-20_14-51-00-500_%06d.png -pix_fmt yuv420p movie.mp4

• 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 :
