Stabilize drone footage locally with no upload

FFmpeg's deshake filter is a basic translational motion correction — it compensates for left/right/up/down shake but does not handle rotation, zoom, or rolling shutter (Jello effect). For moderate handheld shake, results are good. For severe shake, heavy rotation, or rolling shutter from CMOS sensors, professional stabilisation tools (Adobe Warp Stabilizer, DaVinci Resolve Tracker) produce significantly better results.

When stabilisation shifts frames to compensate for movement, a border appears at the edges of frames. Edge fill handles this border: 'crop and zoom' crops the output slightly and upscales to hide the border (reduces effective field of view). 'Border fill' keeps the original field of view and fills the border edges with a blurred or repeated pixel region. Crop and zoom generally looks cleaner.

No — rolling shutter is caused by the sensor scanning line-by-line during fast movement, creating a 'Jello' wobble effect. This is a pixel-level distortion, not a frame-level shift, and FFmpeg's deshake filter does not correct it. Rolling shutter correction requires dedicated lens-distortion filters or professional NLE plugins. Avoid the problem at capture by using a gimbal or global-shutter camera.
