Video to COLMAP for tttLRM

Standalone Hugging Face Space that converts an uploaded video into a raw COLMAP scene archive suitable for the tttLRM inference Space.

What it does

• —Normalizes uploaded video with ffmpeg
• —Samples candidate frames across the clip
• —Scores sharpness, scene cuts, and inter-frame motion
• —Chooses an ordered keyframe set with overlap appropriate for COLMAP
• —Runs CPU COLMAP (feature_extractor, sequential_matcher, mapper)
• —Packages a raw scene archive with:
• —images/
• —sparse/0/
• —report.json

Recommended workflow

1. 1.Upload a short orbit or slow pan video of a single object or scene.
2. 2.Download the generated raw COLMAP .zip.
3. 3.Upload that archive into the companion tttLRM inference Space.

Notes

• —This Space is CPU-oriented because COLMAP runs on CPU in standard Hugging Face Spaces more reliably than GPU-specific builds.
• —Best results come from a stable single-shot orbit video with limited lighting changes and no jump cuts.
