概要
This skill automates the complex process of joining videos using FFmpeg, providing an interactive interface to handle diverse media assets. It intelligently switches between the high-speed 'concat demuxer' for identical formats and the robust 'concat filter' for files with mismatched resolutions or codecs. The skill proactively manages technical hurdles like aspect ratio normalization through scaling and padding, while offering creative controls for transition effects, audio handling, and custom output configurations.
