ComfyUI Node
(Deno) LTX High resolution Tiled Sampler
DENO Custom Nodes vunknown. The DENO info button checks Comfy Registry and marks this node when an update is available. Refines the video half of an LTX AV latent with step-fused spatial tiles while passing the full audio latent to every tile as context. Audio is kept unchanged so the second pass can use audio sync without re-denoising the sound. Guide-bearing LTX latents are tiled with their guide metadata preserved; for guide-bearing output, run LTXVSeparateAVLatent first, then apply LTXVCropGuides to the video latent before decode.

Inputs (12)
| Name | Type | Default | Description |
|---|---|---|---|
| noise | NOISE | Noise source used once for the global AV sampler trajectory. | |
| guider | GUIDER | BasicGuider or CFGGuider for the LTX AV second pass, including LTX guide metadata from upstream Sequencer/Add Guide nodes. | |
| sampler | SAMPLER | ComfyUI sampler object. The node keeps the sampler update global. | |
| sigmas | SIGMAS | Sigma schedule for the low-denoise AV second-pass refinement. | |
| latent_image | LATENT | LTX AV nested latent containing video and audio. If guides are present, run LTXVSeparateAVLatent after this sampler, then apply LTXVCropGuides to the video latent before decode. | |
| horizontal_tiles | INT | 21–8 | Frame width split count. 2 means left and right tiles. |
| vertical_tiles | INT | 21–8 | Frame height split count. 3 means top, middle, and bottom tiles. |
| overlap | INT | 81–32 | Overlap in latent video tokens for each model-prediction tile, including guide-bearing video frames. |
| audio_modeopt | COMBO | freeze | Freeze keeps audio unchanged while still using it as context for video denoising. |
| blend_modeopt | COMBO | hann | Overlap weighting curve. Hann is the recommended starting point. |
| aggressive_memory_cleanupopt | BOOLEAN | true | Run extra cleanup between AV tile predictions. This can be much slower, but may help fragmented VRAM or OOM cases. |
| debugopt | BOOLEAN | false | Print AV hook calls, sigma labels, and tile diagnostics to the ComfyUI console. |
Outputs (2)
| Name | Type | Description |
|---|---|---|
| output | LATENT | Refined AV latent. Video is tiled with guide metadata preserved and audio is preserved from the input. |
| denoised_output | LATENT | Denoised AV latent from the callback x0. Video is x0 with guide metadata preserved and audio is preserved from the input. |
