This Skill enables automated, repeatable media processing by orchestrating ffmpeg/ffprobe tasks—inspecting, converting, trimming, resizing, compressing, extracting frames and audio, replacing audio, creating GIFs, adding subtitles and overlays, and stitching videos together.
Inspect the input with ffprobe, then encode or copy to the desired output format and verify the result with ffprobe.

To trim video clips without re-encoding, use ffmpeg with stream copy (-c copy) and specify start and end timestamps. This extracts the segment directly from the container, preserving original quality and ensuring fast processing.
Extracting frames from a video for thumbnails is done using ffmpeg by specifying a frame rate or select filter. This generates a sequence of image files capturing specific moments, suitable for batch thumbnail generation and storyboards.
ffprobe inspects media file metadata by querying the container format, individual streams, duration, and codec details. It outputs structured data that validates input characteristics before applying processing commands.
Yes, ffmpeg supports batch transcoding and compression workflows by iterating commands across multiple files. It handles container and codec decisions, re-encoding inputs to target formats while applying validation and compatibility checks.
Burning subtitles and image overlays into a video uses ffmpeg filter complexes to render text or graphics directly onto video frames. This permanently embeds the visual elements into the output stream during the re-encoding process.
Stitching videos with mismatched codecs or resolutions requires ffmpeg to re-encode for uniformity, ensuring seamless concatenation. When properties match, -c copy can stitch without re-encoding, but incompatible streams force a re-encode.
