The most reliable method does not require a special "hacker tool." It is built directly into FFmpeg, the Swiss Army knife of video processing. The delogo filter is designed to remove TV channel logos, but it works for any static watermark.

Extremely fast, no quality loss outside the watermark zone, native to most systems. Cons: Leaves a slight blur patch if the watermark is large; only works on static (non-moving) watermarks. 2.

Invisible removal; can remove moving objects or text overlays. Cons: Requires a powerful GPU (NVIDIA CUDA cores), very slow (minutes per second of video), high RAM usage. 3.
