In the last step we add information about how much the video is speed up right above our clock.Ĭonvert to GIF ffmpeg -i timestamp_final.mp4 -loop -1 timestamp_final.gifĪnd at last we generate GIF out of our MP4. We speed it up 35 times which you can easily changeĪdd speed-up information ffmpeg -i speedup_timestampImage 03-11-2020 at 17.05.jpeg.mp4 -vf 'drawtext=fontfile=/usr/share/fonts/truetype/dejavu/DejaVuSans.ttf:expansion=normal: text='x35 speed': fontcolor=orange:fontsize=48: x=(w-text_w)/2: y=h-th-60' -vcodec libx264 -vb 2600k -strict -2 -preset slower -f mp4 timestamp_final.mp4

Here, we speed up the video to make the 'timelapse'. Speed up the video ffmpeg -i timestamp_clock.mp4 -an -vf 'setpts=PTS/35' speedup_timestamp.mp4 In the first step we take our input movie input.mov and add at bottom center a black box with white timestamp Skip the first 10 seconds of the video and make a 5 second gifĪdd -ss 10 and -t 5 to the ffmpeg command.Ffmpeg - GIF timelapse with timestamp clockĪdd timestamp clock to video ffmpeg -i input.mov -vf 'drawtext=fontfile=/usr/share/fonts/truetype/dejavu/DejaVuSans.ttf:expansion=normal: text='%': fontcolor=white:fontsize=48: x=(w-text_w)/2: y=h-th-10: box=1: boxcolor=black: boxborderw=5: line_spacing=32' -vcodec libx264 -vb 2600k -strict -2 -preset slower -f mp4 -an timestamp_clock.mp4

- layers Optimize - : optimizes the resulting gif greatly reduces file size especially if the frames have a lot of similar images (e.g.

-delay : specify the pause between frames I make this equal to -r option in ffmpeg.

-vf scale=n:-1:flags=lanczos : I add this to the ffmpeg command when I want to force the gif to be a different resolution than the source video while keeping the quality high, n = frame width.

-r : set the frame rate I make this equal to -delay option in convert.

-t : duration specify the length of gif to create.

-ss : start time offset specify the time of the video to start extracting the frames/creating the gif.

You can check the help or man pages of ffmpeg and convert for more details about the available options but here are a few that I’ve found to be the most useful. Ffmpeg -i -r 10 -f image2pipe -vcodec ppm - | convert -delay 10 -loop 0 -layers Optimize.
