Are the generated reports portable?

Absolutely. The HTML reports are self-contained with all visual data embedded as base64 URLs, allowing them to be viewed offline or shared without external assets.

How can I speed up the comparison process?

You can use the --interval flag to increase the time between sampled frames, which reduces the number of frames processed and shortens analysis time.

Can I compare videos of different formats?

Yes, the tool supports common formats like MP4, MOV, AVI, MKV, and WebM, provided they are readable by FFmpeg.

Do I need external software to use this skill?

Yes, you must have FFmpeg and FFprobe installed on your system as they are required for frame extraction and metadata analysis.

What metrics does the Video Comparer provide?

It calculates PSNR (Peak Signal-to-Noise Ratio) for pixel-level similarity and SSIM (Structural Similarity Index) for perceptual quality analysis.

分析与监控

Compares video files to generate interactive HTML reports with visual comparisons and objective quality metrics like PSNR and SSIM.

This skill provides a robust automated workflow for analyzing video compression efficiency and visual fidelity. By leveraging FFmpeg and Python, it extracts frames and calculates objective quality metrics (PSNR and SSIM) to compare original and processed videos. The tool generates a self-contained, interactive HTML report featuring multiple viewing modes like sliders and side-by-side grids, making it an essential utility for developers, video engineers, and content creators who need to validate codec performance, bitrate optimization results, or visual regression in video pipelines.
