`vae_tiling_params.tile_size_w` and `tile_size_h` are in **image pixels**, with `0` selecting the 256-pixel default. Both encode and decode use these sizes without an encoding multiplier. Positive `rel_size_w`/`rel_size_h` values override the corresponding absolute size: values up to 1 are dimension fractions, and values greater than 1 are target tile counts. Set `enabled` to use spatial tiling. Sizes are aligned down to the VAE scale factor and capped at the input dimensions; explicit sizes below the minimum supported tile size are rejected. These fields previously used latent units; see [VAE tiling](../../docs/performance.md#use-vae-tiling-to-reduce-encode-and-decode-memory-usage) for migration and OOM retry behavior.
`vae_tiling_params.extra_tiling_args` accepts a key=value list. Supported video VAEs accept `temporal_tile_frames` (alias `temporal_tile_size`, default `4`) and `temporal_tile_overlap` (default `1`).
LTX and Wan preserve causal state between temporal tiles. Hunyuan Video and TAEHV use overlap blending. MiniMax H3 keeps its model-specific fixed temporal windows because its latent-to-frame mapping is non-linear.
