Stabilise Video Using FFmpeg

FFmpeg provides a method for stabilizing video using a two-pass approach. The first pass involves using the `vidstabdetect` filter to analyze the video and generate stabilization data, which is saved in a file named `transforms.trf`. Users can adjust parameters such as shakiness, accuracy, and stepsize to optimize the detection process. For example, a command to analyze a very shaky video might look like `ffmpeg -i clip.mp4 -vf vidstabdetect=shakiness=10:accuracy=15 -f null -`, while using default parameters can be done with `ffmpeg -i clip.mp4 -vf vidstabdetect -f null -`. The second pass employs the `vidstabtransform` filter to create a stabilized video based on the data from the first pass. This step also allows for adjustments in smoothing, interpolation, and zooming, although default settings often yield satisfactory results. A typical command for this step is `ffmpeg -i clip.mp4 -vf vidstabtransform stabilised-clip.mkv`. Users can combine both passes into a single command for efficiency. Additionally, Kdenlive offers similar stabilization parameters for users who prefer a graphical interface.
