Creating timelapse videos on linux

This is the first timelapse i did using my new GoPro Hero2.
It’s set up of about 2000 photos taken in ~2:30h.

Assembly Process (slight commenting)

Tools used:

  • ffmpeg
  • mencoder
  • kdenlive
  • MP4Box (Archlinux package: gpac)
Sorting input images

ffmpeg expects the input images to have incremental  numbers without offset. so one can get them in this format with whatever tool of choice. gqview e.g. allows series renaming and would do that job fine. or just use the cmdline(shell + perl) like i did:

~inputfiles/order/ now holds images as ffmpeg expects them.

Creating the timelapse

now, this creates a timelapse video of 25 frames per second. this might fit well in a lot of situations. but in my case the timelapse seemed to be a bit to fast rushing by.

Using mencoder to slow it down

play with the -speed value a bit.

once i was satisfied with the result i pushed slow.mp4 into a kdenlive project, added some music, fade in/out effects and rendered to mp4.
note to myself: investigate further on how this step be done with ffmpeg/(cmdl)

Converting for online playback

For my embedded wordpress player i wanted to resize the video, lower the bitrate and create streaming compatible metadata:





  1. You can do the renaming with a oneliner;

    ls *.JPG| awk ‘BEGIN{ a=0 }{ printf “mv %s file_%04d.jpg\n”, $0, a++ }’ | bash

  2. Or:
    mkdir order; i=0; for file in $(find . -name “*.JPG” | sort); do cp $file order/$(printf ‘%05d’ $i).jpg; i=$(($i+1)); done

  3. Thank you very much. This was very helpful.

    I just want to note that “;” before “| sort |” gave the following error:
    bash: syntax error near unexpected token `|’

    I just removed “;” and everything is okay.

    • Glad this was of help for you.
      Thanks for letting me know about this mistake. I corrected it in the post.
