Command
Example shown — adjust the options above for your own task.
How it works
- Choose the task you want — resize, extract audio, trim, or convert.
- Fill in the relevant options for that task.
- Copy the generated ffmpeg command into your terminal.
Building maps your chosen task and options to the correct ffmpeg
flags — -vf scale, -ss/-t,
-c:v/-c:a — assembled in the right order,
so you don't need to memorize ffmpeg's flag syntax.
FAQ
Is my video uploaded anywhere?
No. This tool only builds the command text — it doesn't process any video itself, and nothing is uploaded.
What tasks are supported?
Resizing, extracting audio, trimming a clip, and converting between formats — the most common everyday ffmpeg operations.
Do I still need ffmpeg installed to use the command?
Yes — this generates the command text for you to run in your own terminal where ffmpeg is installed; it doesn't run ffmpeg itself.
Can I copy the command directly?
Yes — a copy button puts the full command on your clipboard, ready to paste into a terminal.
