Why architecture matters here

AV1 fails on wrong preset (quality or speed), missing HW support, and rate control misconfig. Architecture matters because tiles + parallelism + preset are joint.

The architecture: every piece explained

The top strip is encoding. Raw frames. Tiling parallel columns/rows. Partition tree. Intra + inter prediction.

The middle row is compression. Transform + quant. Entropy coding. Rate control. Loop filters.

The lower rows are ops. HW encode. Quality metrics VMAF/SSIM. Ops — presets + hw fallback.

End-to-end flow

End-to-end: 4K frames tiled into 4 columns. Partition tree subdivides super-blocks. Prediction + transform + entropy. Rate control targets CRF 30. Loop filters clean. VMAF 92. HW offload on Ada GPU reduces CPU to 10%.
