does your submission require gpu for evaluation (inflation)?

no

did you include the compression script? and want it to be merged?

yes

additional comments

SVT-AV1 v2.3.0 with 10-bit encoding, AV1 film-grain synthesis (no denoising), and infinite GOP.

  • Encoder: SVT-AV1 v2.3.0 (built from source; older version outperformed v3.x/v4.x on this content)
  • 10-bit YUV420: better rate-distortion efficiency than 8-bit even with 8-bit source
  • CRF 34, preset 1
  • Infinite GOP (--keyint -1): no forced keyframes for a 60s dashcam clip with no scene cuts
  • Film-grain 30, denoise=0: grain synthesis adds temporal consistency for PoseNet, but disabling the internal denoiser preserves source edges for SegNet
  • 50% Lanczos downscale (582x436) with decoder-side bicubic upscale + unsharp mask (5x5 Gaussian, sigma=1.0, amount=2.0)

Key finding: the combination of no denoising + film-grain synthesis + infinite GOP + 10-bit is critical. Each contributes ~0.03-0.05 to the score. Disabling any one regresses to ~2.05+.

Fun fact: I built an evaluation judge for myself on a Google Cloud T4 instance in Taiwan (couldn’t find an available T4 anywhere in North America lol).
