Capture method
Video capture
Record one continuous or carefully paced walkthrough.
Still-photo sequence
Take individual photos from planned positions.
Video to 3D
Create a 3D Model with realityscan from video
realityscan from video is a practical way to use recorded footage as the source for a 3D reconstruction. Instead of planning every still image manually, you capture a steady path around the subject and let overlapping frames provide the visual coverage needed for geometry and texture.
Why Video to 3D Works
A video contains many overlapping viewpoints, but the quality of the final reconstruction depends on how consistently those viewpoints cover the subject.

Still-photo sequence
2
Overlap
Video capture
Built into adjacent frames when movement is steady.
Still-photo sequence
Must be planned and checked between each image.
3
Motion control
Video capture
Requires slow movement and limited subject motion.
Still-photo sequence
Allows more deliberate pauses and repositioning.
4
Coverage speed
Video capture
Efficient for large objects and simple paths.
Still-photo sequence
More deliberate but easier to inspect as you go.
5
Frame selection
Video capture
May need unsuitable or blurred frames removed.
Still-photo sequence
Each image can be reviewed before processing.
6
Best use
Video capture
Walkarounds, environments, sculptures, and quick capture.
Still-photo sequence
Small details, controlled lighting, and repeatable documentation.
7
Main risk
Video capture
Blur, exposure shifts, and uneven pacing can reduce detail.
Still-photo sequence
Gaps between viewpoints can create incomplete surfaces.
From Moving Frames to a Finished Surface
The useful transformation is not simply video in and mesh out. Good coverage gives the reconstruction process enough consistent visual evidence to connect surfaces and preserve recognizable detail.
Recorded video
Capture consistency is the bridge between the two states.
Who Benefits from This Workflow
Choose the capture style that matches the subject, then refine the result for its intended destination.
3D printing hobbyist
Record a slow walk around a physical object with full coverage of its visible sides.
Use the resulting mesh as a starting point for cleanup, scaling, and print preparation. See the practical workflow in realityscan for 3d printing.

The Tool Block: Capture to Model
Keep the path simple and make each stage intentional so the reconstruction has consistent evidence to work from.
Plan the path
Choose a subject with visible features, even lighting, and enough space to move around it. Decide how you will cover the top, sides, and difficult rear areas.
Record steadily
Move slowly at a consistent distance while keeping the subject in frame. Avoid rapid pans, heavy blur, sudden exposure changes, and unnecessary zooming.
Review and reconstruct
Inspect the footage for gaps or unusable motion, then process the strongest coverage into a model. Check the surface for holes, noise, and texture misalignment.

realityscan from video FAQ
Answers to common questions about using recorded footage as the input for a 3D reconstruction.
A video can provide a sequence of overlapping views that may be used as source imagery for reconstruction. The result depends on extracting or accepting suitable frames and on the consistency of the recording.
Use a steady recording with the subject kept in frame, even lighting, and a slow path around the object. Avoid blur, fast pans, changing distance, and moving subjects whenever possible.
For a full object, walk around it or follow a path that exposes its sides and top while maintaining a similar distance. A single viewpoint usually leaves hidden surfaces without enough visual information.
It can be a useful starting point, but the reconstructed model should be checked before printing. Inspect scale, watertightness, holes, thin areas, and surface noise, then repair the mesh in a suitable modeling tool.
