FFmpeg Frame Extraction
To extract key frames (I-frames) from a video file using FFmpeg, use the following command:
ffmpeg -i input_video.mp4 -vf "select='eq(pict_type,PICT_TYPE_I)'" -vsync vfr output_folder/keyframes_%03d.png
-i input_video.mp4: Input video file.-vf "select='eq(pict_type,PICT_TYPE_I)'": Video filter to select only key frames.-vsync vfr: Variable frame rate to match input frame rate but only save selected frames.output_folder/keyframes_%03d.png: Output pattern for filenames.

glm-output
Output-processing guidance for GLM tasks. Especially useful after glm-basics and glm-calibration when you need verifier-matching metrics from output.nc and a final /root/metrics.json.
glm-calibration
Calibration guidance for GLM tasks. Often most effective after glm-basics has clarified the setup; glm-output is the companion skill for exact final metric computation.
glm-basics
A good starting point for GLM calibration tasks. Use to inspect glm3.nml, confirm how GLM runs, and identify the relevant files before moving on to calibration and output evaluation.
