Part 1. Basic FFmpeg Commands to Speed Up Videos
Unlike multimedia tools and traditional audio editors, FFmpeg works exclusively in your computer’s command terminal, as it was designed as a command-line software suite for editing files, commonly for format conversion, recording, and audio and video editing.
Since it is fully command-based and lacks a built-in graphical user interface (GUI), editing files in FFmpeg is done exclusively via command lines that its users must already know. Unfortunately, this is not the most beginner-friendly approach, so it is not the best choice for all users, especially those who only want to speed up videos on TikTok or other short-form content.
If you want to get started with using FFmpeg as a multimedia tool, we’ve provided some basic speed-up commands below. These commands are all you need in FFmpeg to make playback adjustments.

Keep Video In-Sync: ffmpeg -i input.mp4 -filter_complex “[0:v]setpts=0.5*PTS[v];[0:a]atempo=2.0[a]” -map “[v]” -map “[a]” output.mp4
Speed-Up Multiplier (2X): ffmpeg -i input.mp4 -filter_complex “[0:v]setpts=0.5*PTS[v];[0:a]atempo=2.0[a]” -map “[v]” -map “[a]” output.mp4
No Audio Video Speed Up: ffmpeg -i input.mp4 -filter:v “setpts=0.5*PTS” output.mp4
Audio Only Speed Up: ffmpeg -i input.mp4 -filter:a “atempo=2.0” output.mp4
Speed Up With Re-Encoding for Quality: ffmpeg -i input.mp4 -filter_complex “[0:v]setpts=0.5*PTS[v];[0:a]atempo=2.0[a]” -map “[v]” -map “[a]” -preset fast -crf 23 output.mp4
Speed Up All File Formats (MP4): for %i in (*.mp4) do ffmpeg -i “%i” -filter_complex “[0:v]setpts=0.5*PTS[v];[0:a]atempo=2.0[a]” -map “[v]” -map “[a]” “fast_%~ni.mp4”
With all these command lines now discussed, let us move on to the tutorial on using FFmpeg to help our readers apply these commands to the media files they want to edit. Please proceed to the next section of the article to learn how to use FFmpeg to speed up videos in MP4, MKV, MOV, or any video format.
Part 2. How to Speed Up Video with FFmpeg
Speeding Up Video with Audio Sync
The first tutorial in this guide shows how to use FFmpeg to speed up videos by 2X. This playback multiplier was selected because it is often the standard option for maintaining audience attention in short-form content.
Open your computer’s command-line software. On Windows, open Command Prompt. On macOS, open your device’s Terminal.

In your command software, copy and paste the speed-up multiplier command we have provided above: ffmpeg -i input.mp4 -filter_complex \"[0:v]setpts=0.5*PTS[v];[0:a]atempo=2.0[a]\" -map \"[v]\" -map \"[a]\" output.mp4.
Once the command has been pasted, edit the input.mp4 and output.mp4 commands. Rename the input to the name of the video you want to speed up, and adjust the output to how you want the sped-up video to be saved. With the Input and Output name now set, press Enter to begin the speedup adjustment.

Using this command, you can now apply simple audio speed adjustments to your FFmpeg command software.
Batch Processing Multiple Videos
To batch process multiple videos on your computer, the simplest option is to apply the playback adjustment to all videos in your set format. In this case, the guide features batch processing of all videos saved as MP4 files.
Open your computer’s command line software.

In the command terminal, copy and paste the command to batch-process videos in a set format. In this case, MP4 videos: for %i in (*.mp4) do ffmpeg -i \"%i\" -filter_complex \"[0:v]setpts=0.5*PTS[v];[0:a]atempo=2.0[a]\" -map \"[v]\" -map \"[a]\" \"fast_%~ni.mp4\".
If you want to change the video format of the videos you want to speed up, edit the desired format to the end of the command.

Although it is not the best, speeding up all files saved in a defined format still gets the job done. As such, we recommend using this command if you are sure that the videos you want to edit are saved in a uniform file type.
Part 3. Best Alternative to FFmpeg to Speed Up Video
With the command-line options for video speed-up in FFmpeg now discussed, their advanced nature is definitely not ideal for amateurs. Using command lines also carries a significant risk if you make a mistake while editing media files.
