About:
QCTools is a powerful tool for analyzing, visualizing, and filtering video files to detect technical errors and quality issues. It leverages FFmpeg's libavfilter library to provide detailed frame-by-frame data on video and audio streams. Its main value is enabling quality control and restoration workflows for digital video preservation.

Key Features:

Graphical visualization of video and audio parameters over time
Frame-by-frame filtering and error detection
Support for a wide range of formats via FFmpeg
Export of filtering decisions to XML or FFmpeg scripts
Real-time monitoring of stream integrity

Use Cases:

Quality control for video digitization and restoration projects
Detecting and diagnosing video artifacts and encoding errors
Filtering specific video frames based on technical metadata

Alternatives:

FFmpeg – FFmpeg provides the underlying engine but lacks the interactive graphical interface for visualization.
MediaInfo – MediaInfo provides detailed technical metadata but does not offer frame-level visualization or filtering capabilities.
