Changing video angles in a multi-angle video involves selecting which camera angle to display at any given time.

| Parameter | Value | |-----------|-------| | Total images | 173 | | Capture duration | 16 minutes | | Shutter‑speed settings | 1/2000 s, 1/1000 s, 1/500 s, 1/250 s (four groups) | | ISO | 200 (constant) | | Aperture | f/2.8 | | Frame interval | ~5.5 s | DD-s SS Olivia 026 Angle Crop 173pics 16min 4...

The four shutter‑speed groups (denoted 4… in the original note) were interleaved to assess robustness across exposure regimes. Changing video angles in a multi-angle video involves

| # | Contribution | |---|--------------| | 1 | Introduce a reproducible Angle‑Crop pipeline (rotation + crop) for DD‑S/SS data. | | 2 | Provide a quantitative evaluation on a real‑world dataset (Olivia‑026, 173 photos, 16 min). | | 3 | Release the source code and processed dataset under a CC‑BY‑4.0 license. | If your goal is to learn about editing

If your goal is to learn about editing videos, specifically changing angles or cropping, here's a basic guide:

| Issue | Impact | Mitigation | |-------|--------|------------| | Extreme rotations (> 5°) | Cropping loss > 12 % | Combine with multi‑frame stitching | | Real‑time streaming | Additional latency | Batch‑process on GPU (≈ 0.5 ms/frame) | | Non‑planar subjects | Angle estimation may be noisy | Use facial landmarks instead of edges |

The DD‑S/SS sensor’s micro‑optic displacement introduces a small but measurable rotational offset (average |𝜃| ≈ 1.7°). By correcting this offset before cropping, the algorithm:
