Need to cut the edges off a video — drop a watermark band, reframe to square for a feed, or change the aspect ratio? That’s a region selection, not a re-shoot.
FFmix gives you a visual crop box with ratio locks, then runs the exact ffmpeg crop filter on your Mac — nothing uploaded. The cropped copy lands next to the original, and you can see the command first.
Steps
- 1 Drag your video into FFmix.
- 2 Pick the Crop frame task and drag the box (or lock a ratio like 1:1 or 9:16).
- 3 Confirm and click Start — the cropped video saves next to the original.
Advanced: canonical ffmpeg recipe
This is the canonical recipe. FFmix adapts encoder flags to the engine on your Mac, then shows the final command; the command shown is the command run.
ffmpeg -i input.mp4 -vf "crop=1080:1080:0:0" -c:a copy cropped.mp4 Drop a file and go — all local, nothing uploaded.
FAQ
Can I crop to an exact aspect ratio?
Yes. FFmix's visual crop has ratio locks (1:1, 4:5, 9:16 and more), so you can frame a square or vertical version without doing the math.
Does cropping re-encode the video?
Cropping changes the picture, so the video track is re-encoded; FFmix keeps the audio untouched with `-c:a copy`, and the visual quality stays high.
Is anything uploaded?
No. Cropping runs locally through the bundled ffmpeg engine; your video never leaves your Mac.
