To compare video quality, you can calculate PSNR and SSIM metrics to quantify compression impact and generate interactive visual reports. This process evaluates frame-by-frame differences using side-by-side and grid modes for detailed analysis.

PSNR and SSIM metrics quantify the quality degradation in a compressed video. They measure structural similarity and signal-to-noise ratios between original and compressed frames, providing objective scores to evaluate compression impact.

Yes, you need FFmpeg and FFprobe installed to analyze video metadata and quality. These dependencies are required to extract codec, resolution, frame rate, and bitrate details, and to perform the underlying video processing.

You can extract video metadata like codec, resolution, frame rate, and bitrate using FFprobe. This extracts essential video details to help you understand the technical properties before performing detailed quality assessments.

Yes, you can perform a frame-by-frame comparison of compressed videos using interactive sliders, side-by-side, and grid modes. This allows detailed visual inspection of compression artifacts and quality loss across individual frames.

Compression quality analysis is compatible with a range of video formats, as long as FFmpeg and FFprobe can process them. This format flexibility allows you to evaluate various original and compressed video files.
