Does it support color space verification?

Yes, it checks color primaries, matrix coefficients, and transfer characteristics to ensure they match industry standards like BT.709 for HD content.

Can this skill tell me if a video is 'fake' 4K?

Yes, it analyzes metadata for red flags such as resolutions that do not match the expected source characteristics or bitrates that are suspiciously low for high-resolution headers.

What is the difference between remuxing and reencoding in this context?

The skill identifies if you only need to change the container (remuxing), which is fast and lossless, or if the actual video data needs to be processed (reencoding), which takes longer and may involve quality loss.

What software is required to use the Video Audit skill?

This skill requires the MediaInfo CLI tool. It can be installed via Homebrew on macOS, apt on Linux, or downloaded from the official MediaArea website for Windows.

内容管理

Analyzes video files to extract technical metadata, identify quality issues, and provide optimization recommendations.

关于

The Video File Audit skill leverages the MediaInfo CLI to perform deep technical inspections of multimedia files. It assists users in navigating the complexities of video production by distinguishing between containers and codecs, verifying color space parameters (like BT.709 vs BT.601), and detecting quality red flags such as upscaling, interpolated frame rates, or 'fake' HDR. This skill is essential for ensuring file compatibility and maintaining high-quality standards before archival, streaming, or editing.
