Using FFmpeg to Generate Videos
It's not an editor… it's a Swiss Army knife for automating your production.
FFmpeg allows you to create complete videos without touching a traditional editor:
you can combine images, audio, animations, transitions, dynamic text,
and generate multiple versions of the same content with a single command.
The best part is that you don't need to drag, drop, or move anything.
Just define your template and let FFmpeg build the clips
automatically—perfect for TikTok, Reels, and daily content publishing.
Below is a real example of how to generate a simple video
from an image and an audio file:
ffmpeg -loop 1 -i background.png -i audio.mp3 -c:v libx264 -t 15 -pix_fmt yuv420p -vf "scale=1080:1920,setsar=1" output.mp4
What does this command do?
- -loop 1 -i fondo.png : keeps the image on screen for the entire video.
- -i audio.mp3 : adds the audio you want to use.
- -t 15 : generates a 15-second video.
- scale=1080:1920 : adjusts to the vertical TikTok format.
- pix_fmt yuv420p : ensures full compatibility with social platforms.
These kinds of commands can become reusable templates to generate dozens or hundreds of videos effortlessly.
In my current workflow, FFmpeg handles:
- Generating videos from one or several images.
- Adding subtitles and phrases automatically.
- Synchronizing audio with the content.
- Creating variations of the same clip with zero manual work.
