additional comments
SVT-AV1 with 45% spline downscale, CRF 32, preset 0, GOP 180, film-grain=22 (denoise+synth).
The key insight: ffmpeg's
splinedownscale algorithm preserves PoseNet-relevant temporal features better thanlanczosat this scale factor. Combined with film-grain synthesis (which strips sensor noise before encoding for cleaner inter-frame consistency that PoseNet rewards), this achieves PoseNet distortion of 0.081 — meaningfully lower than equivalent lanczos-based configurations.
