Qwen2.5VL MinMax watermark/subtitle removal. When describing the position of subtitles and watermarks, be more specific, for example: the Douyin watermark in the top-left corner. For relatively simple videos, you can directly input the watermark and subtitles. Simultaneously removing watermarks and subtitles may result in the entire frame being removed. If this occurs, you can remove them step by step, first removing the watermark and then the subtitles.
