| Level / buffer | AV1 Annex A: the lowest level (main tier; high tier only when main does not fit) that covers the resolution, sample rate and the actual bitrate. seq_level_idx / seq_tier in the sequence header are patched to that level. Buffer in the name = the level's BufferSize (MaxBitrate × 1 s). |
|---|
| Structure | 60 frames = 2 GOP × 30 (keyframes at frames 0 and 30, no scene-cut keyframes), random access with a B-pyramid, profile 0 (Main), bit depth as in the source, IVF container. Single tile. |
|---|
| Verification | aomdec md5 of the luma plane, keyframes 0 and 30, PSNR-Y / SSIM-Y against the source luma. |
