What is Video to keyframes 2D?
Extract 2D OpenPose keyframes from a video and export a skeleton preview + keypoints JSON for Unity/Unreal 2D workflows.
Extract 2D OpenPose keyframes from a video and export a skeleton preview + keypoints JSON for Unity/Unreal 2D workflows.
Inputs and outputs
Add the source media requested by this workflow, then review and export the generated result.
Describe the result
Use concrete details such as subject, action, camera, mood, lighting, and duration when supported.
What you can do with the outputs
This workflow turns a video into a 2D skeleton/keypoints timeline (OpenPose) plus a preview video you can compare side-by-side.
Preview
- Compare original video vs keyframes preview (2D skeleton) side-by-side
- Quickly evaluate tracking quality (pose + face + hands when visible)
- Use as a reference for animators and technical artists
Unity/Unreal 2D pipelines
- Import keypoints JSON into tooling (editor scripts) to drive 2D rigs or constraints
- Create flipbooks / Paper2D previews from the exported keyframes video
- Build authoring tools: pose matching, hitbox guides, timing markers
Limitation: This is 2D only (screen-space keypoints). It is not a 3D mocap solver and is not directly retarget-ready for 3D rigs.
