Stratification (alternatively, flow chart or run chart).Cause-and-effect diagram (also known as the "fishbone diagram" or Ishikawa diagram).They are called basic because they are suitable for people with little formal training in statistics and because they can be used to solve the vast majority of quality-related issues. This can easily be wrapped in a script to create many qctools files during the preservation process.The seven basic tools of quality are a fixed set of visual exercises identified as being most helpful in troubleshooting issues related to quality. By default, this file will be saved to the same directory and named after the file, e.g. After installing it, you can run qcli -i to generate a qctools report based on your file. QCTools files can also be generated via the command line with qcli. Incorporating a set of open source libraries developed under the ffmpeg project, the QCTools document offers metadata values derived from four evaluative filters: signalstats, cropdetect, psnr, and ebur128. The QCTools document (built upon FFprobe's xml expression), is designed to be self-descriptive, storing analytical metadata about video and audio frames. The playback window includes two viewing windows which may be set to different combinations of filters. The QCTools preview window is intended as an analytical playback environment that allows the user to review video through multiple filters simultaneously. QCTools offers a variety of Graphing Options including: YUV Values, Temporal Outliers (TOUT), Vertical Line Repetitions (VREP), Broadcast Range (BRNG), Crop Width and Height (CropW and CropH), and Peak Signal to Noise Ratio (PSNRf) and Mean Square Error (MSEf) differences per frame.
