Does this skill re-encode every video during conversion?

No, the skill first probes the video with ffprobe to see if a lossless remux is possible using stream copying, which is faster and preserves original quality.

Can I combine multiple operations like trimming and resizing at once?

Yes, the skill is specifically designed to chain multiple filters into a single FFmpeg invocation to avoid quality loss from multiple re-encodings.

How does it handle audio when changing video speed?

The skill uses the atempo filter to synchronize audio with video speed changes, ensuring the sound remains intelligible and in sync.

Can I extract multiple frames as a sequence?

Yes, you can extract a single frame at a specific timestamp or a series of frames at defined intervals using high-quality JPEG settings.

Will rotating a video work on all players?

Yes, rather than just changing metadata tags, this skill bakes the rotation into the actual video pixels to ensure compatibility across all media players.

Processes, converts, and edits video files using optimized FFmpeg commands for format changes, trimming, and effects.

This skill empowers Claude to perform complex video manipulation tasks directly via the command line. It handles a wide array of operations including format conversion, lossless remuxing, precise trimming, playback speed adjustments for slow-motion or timelapses, and intelligent resizing that avoids upscaling. By analyzing file metadata with ffprobe first and chaining FFmpeg filters into single-pass commands, it ensures high-quality output with maximum efficiency and minimal generation of intermediate files.
