Three generated H.264 cases were rerun with FFmpeg 6.1.1. This package includes two source controls, manifests and the original safe generator. The visual cut at 2 seconds in cut_no_scenecut.mp4 is not a decoder-flagged keyframe. Re-run outputs depend on the encoder/build.

Synthetic examples created for ExtractVideoFrames.com. Original example media and illustration data: CC0. FFmpeg, Python, Pillow and ImageMagick are separate tools with their own licenses. Source programs do not delete existing directories; use a new working folder. No private media is included.
