Video Models Keep Getting Heavier: LTX-2.5, Wan 2.2 and MiniMax H3 vs Your VRAM

The pace of new video model support in ComfyUI has been relentless. Recent releases and node updates have brought FLUX.2 Klein, LTX-2.5 (including the LTX Ripple first-frame IC-LoRA), Wan 2.2, MiniMax H3 and H3 Max, ByteDance Seedance 2.5 with 1080p and clip-extend, and Gemini Omni with 4K output and video extend. Motion designers can now ship longer clips, higher resolution, better temporal coherence, lip-sync, and first-frame propagation across a whole shot.
The catch is that capability and appetite move together. Higher resolution and longer frame counts are precisely the variables that blow past VRAM. The community bug trackers tell the real story: LTX-2 hitting out-of-memory at 1080p above 200 frames when the pipeline moves into its upscale pass; Wan 2.2 image-to-video crashing on 16GB cards after a runtime update; upscalers like SeedVR2 OOMing on a card that had headroom moments before. This is Tuesday for a studio pushing client-grade output.
So the models are getting more powerful faster than consumer VRAM is getting bigger, and in 2026, as covered elsewhere in this series, consumer VRAM is barely growing at all. The work everyone wants to make is the work that does not fit on the hardware everyone can actually buy.
Quantization narrows the gap but does not close it at the high end. A hero shot at full resolution and length can still exceed any single consumer card. Use the right card for each job. Iteration and previews run happily on owned nodes. The final, heavy, high-resolution pass, the one that OOMs locally, routes to a cloud node with the VRAM to finish it, then the result comes home.
As long as new models keep outrunning consumer VRAM, a studio needs a way to send the heavy jobs somewhere with more memory, without changing the workflow or the artist's habits. Otherwise an ambitious brief dies at the render.
