The following command will double the speed of audio. Here, you can change value of the -loop setting: To increase or decrease speed up or down audio playback, use the atempo audio filter. 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. #Ffmpeg gif speed up mp4We 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". by default it’s supposed to have the same speed, the -r option only changing the sampling rate. How can I make the GIF to have the speed of the MP4 Thank you Manjaro Linux Forum. Speed up the video ffmpeg -i timestamp_clock.mp4 -an -vf "setpts=PTS/35" speedup_timestamp.mp4 The output of ffmpeg command is this: The original MP4 file is this. #Ffmpeg gif speed up movieIn the first step we take our input movie input.mov and add at bottom center a black box with white timestamp I hope this helps.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 ![]() Entering 60 yields a 60X speedup, entering 0.1 yields a 10X slowdown, and entering 1/30 yields a 30X slowdown. Viewed 591 times 1 begingroup Looking for the best way to speed up or maybe move from FFMpegConverter to another application for converting video to GIF, because it takes much. #Ffmpeg gif speed up codeThis code will prompt you to enter a value and present you with the result. Ask Question Asked 3 years, 10 months ago. The third command speeds the first part ( the too much slow part, so If you follow my example it is named slow. 'ffmpeg -i input.mkv -filter:v "setpts=PTS/' + speed + And you still want to speed up the first part. "<1 is slowdown can use 1/X for slowdown): ", "60")) You can avoid dropped frames by specifying a higher output frame rate than the input. var speed=eval(prompt("Enter speed up or slowdown factor (>1 is speedup, " + ffplay INPUT -vf setpts0.5PTS will drop frames to achieve the desired speed. So if you want 10 sec movie with frame rate 30/sec, you make GIF animation that has total 300 frames, then. The code also works with slowing down the video. Add -r 30 to specify the frame rate 30 frames/sec. Then, copy and paste this code into the console and press Enter to run. In Firefox, type allow pasting into the console to allow copy'n'paste, then Ctrl+A then backspace to remove that text. In the console, to start typing/pasting text, click in the whitespace just right of the blue horizontal chevron (double chevron in FireFox). Enter the speed-up percentage, with 100 being the current GIF speed, 200 being twice as fast, and, for example, 850 being 8.5x as fast. Custom Speed-up Increase the framerate by a custom percentage. ![]() Make a GIF 3x Faster Increase the framerate by 300. Press Ctrl+Shift+I, and click the "console" tab. Make a GIF 2x Faster Increase the framerate by 200. ffmpeg -i input.mkv -filter:v "setpts=PTS/60" -filter:a "atempo=2,atempo=2,atempo=2,atempo=2,atempo=2,atempo=1.875" output.mkv The problem is that atempo cannot be greater than two or less than 0.5, so we must repeat atempo many times to get the sound to the rate that we want it. #Ffmpeg gif speed up downloadInstalling ffmpeg is simple: Just navigate to the official download page here. It may be a bit verbose, but it works great. Saving animated charts or matplotlib animations as gif, avi, mov, mp4 etc. For a stop-motion project where I wanted to reduce the delay between frames (instead of dropping frames), I wanted to speed up the audio and video many times beyond 2x too. ![]()
