Fast Motion Transfer from Video
Precise frame-by-frame motion fitting gives an excellent result but takes a long time. The fast mode in Animatic estimates the person's pose directly from the video and transfers it onto the character in minutes. This is handy when you need to check an idea quickly or get an animation draft.
How the Fast Mode Differs from Precise Fitting
Classic fitting works iteratively: the program refines the skeleton's position many times until it matches the video. The fast mode estimates the pose in a single pass for each frame. The result comes immediately, but the level of detail may be lower.
- Fast mode — minutes; good for drafts, previews and long clips.
- Precise fitting — hours; good for final animation where every detail matters.
What You Get
- A person's movements transferred onto the character's skeleton.
- Support for several people in frame: you can pick the right one manually or leave the choice to the program.
- Ground-position correction so the character neither sinks into the floor nor floats above it.
Computer Requirements
The mode works on NVIDIA graphics cards. For comfortable use, 8 GB or more of video memory is recommended; for long clips and high quality — 12 GB and above. The computations run on your computer; the video is never uploaded to a server.
How to Shoot Video for the Fast Mode
- The camera is stationary, the person fully in frame.
- Good, even lighting.
- One person, with no bystanders in the background if possible.
Detailed shooting recommendations are in the article "Animating a 3D Character from Ordinary Video".
Limitations
- Fast and complex motions, such as acrobatics, may not transfer accurately.
- If the person is heavily occluded by objects or other people, some poses may be estimated with errors.
- For final animation we recommend checking the result and, if needed, switching to precise fitting.
When to Choose Which Mode
The fast mode suits iteration: you try different clips, pick the best one and only then run precise processing. Precise fitting is needed when the animation goes into the final project and every frame has to look flawless.
