Extract Video Keyframes
Use ffmpeg to extract key frames from the video and save them as sequentially numbered PNG files.
ffmpeg -i /root/super-mario.mp4 -vf "select=eq(pict_type\,I)" -vsync vfr /root/keyframes_%03d.png
This extracts only I-frames (keyframes) from the video and saves them as /root/keyframes_001.png, /root/keyframes_002.png, etc., in timeline order.
After extraction, verify the files exist:
ls /root/keyframes_*.png | sort

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.
