MiniMax H3 on RTX 4090 and 5090: Sage and Sol-Attn tested
We reran our MiniMax H3 speed test on an RTX 4090, an RTX 5090 and again on our RTX 3090: Sage Attention, Sol-Attn and latent upscale, real timings, two surprises.
MiniMax H3 in ComfyUI: Motion Director for Longer Videos on RTX 3090
We tested Motion Director on RTX 3090 to get past MiniMax H3's length limit: 3 chained 5s segments in one 15s clip. Pure I2V vs. Ref2VA with a character sheet.
MiniMax H3 in ComfyUI: Real Face Swap with Ref2VA on RTX 3090
We verified MiniMax H3 face swap (RTX 3090) twice: with the creator's own assets and with a 100% self-generated video. The title's 'body swap' isn't shown.
MiniMax H3 in ComfyUI: PDD Acc LoRA (8-Step) vs Turbo (4-Step) on RTX 3090
Alibaba PAI released an 8-step LoRA for MiniMax H3. We tested it on RTX 3090: the 4-step turbo doesn't look bad, it just doesn't advance the choreography over time.
MiniMax H3 in ComfyUI: Sage Attention, Sol-Attn, Latent Upscale on RTX 3090
We tested MiniMax H3 speed tricks on an RTX 3090: Sage Attention, Kijai Sol-Attn, two-stage latent upscale. One hid a real bug no tutorial mentions.
Uni3C ControlNet: Real Camera Control for Wan 2.1 in ComfyUI
I tested native Uni3C ControlNet in ComfyUI on an RTX 3090: point-cloud camera rendering in Docker plus Wan 2.1 generation. Two real blockers fixed.
COMFYCLAW: We Tested the Agent That Builds and Repairs ComfyUI Workflows
We tested COMFYCLAW, the research agent that edits ComfyUI graphs and self-corrects with a visual verifier, using Claude Code as backend on an RTX 3090.
Camera Movement Transfer: IC-LoRA Cameraman v2 + LTX 2.3 in ComfyUI
I tested IC-LoRA Cameraman v2 on LTX 2.3: copies camera movement from a reference video onto a new one, without touching content. Workflow and OOM bug documented.
HunyuanVideo 1.5 in ComfyUI: Real RTX 3090 Install and Test Guide (I2V 480p)
How to install and run HunyuanVideo 1.5 (8.3B, Tencent, open-source) in ComfyUI: exact models, a step-by-step workflow for the I2V 480p step-distilled variant, and the real generation time measured on an RTX 3090.
ComfyUI Upscale Workflow: Ultimate SD Upscale Setup (Free JSON Download)
Upscale ComfyUI images to 4K without running out of VRAM. Ultimate SD Upscale, ESRGAN models, and tiled VAE decode explained -- with a downloadable workflow.
5 Local AI Video Tests on One RTX 3090: What Actually Worked in 2026
LTXV-2.3 distilled, LTXV-2.3 dev, SCAIL-2, Wan 2.1 I2V, and Wan 2.2 I2V, all tested for real on the same hardware. Real timings, real crashes, real quality differences -- not a spec-sheet comparison.
LTX Director in ComfyUI: I Tested the New Timeline Node and Found 2 Real Bugs
Tested the community LTX Director node on top of LTXV-2.3 distilled on an RTX 3090: a version-compatibility bug and an empty-prompt bug, both documented and fixed, plus the real generated video.
I Maxed Out an RTX 3090 with LTX-2.3's Dev Model — It Crashed 4 Times
A reproducible crash 4/4 times running LTXV-2.3's dev model on a 24GB RTX 3090: the bottleneck wasn't VRAM, it was system RAM via the GGUF loader path.
Viral LTXV-2.3 + RTX Super Resolution Workflow in ComfyUI, Reproduced
I reproduce a viral text-to-video-with-audio workflow using LTXV-2.3 chained into RTX Video Super Resolution. Real times, VRAM, and gotchas on an RTX 3090.
SCAIL-2 in ComfyUI: Real Character Replacement Test (No Custom Nodes, RTX 3090)
Tested Comfy-Org's official SCAIL-2 template for AI character replacement: swap a person in any video for a reference image while keeping the scene and motion. Real models, real fixes, real output video.
I Animated the Same Frame with Wan 2.1 I2V That LTXV-2.3 Generated From Scratch
Took the exact first frame from a previous LTXV-2.3 text-to-video test and animated it with Wan 2.1 I2V instead -- a real, controlled comparison of two different local video generation approaches on the same RTX 3090.
Wan 2.2 Video Generation in ComfyUI: Image-to-Video Workflow Guide
Animate any image in ComfyUI with Wan 2.2. Which model size to pick for your GPU, node setup, and motion prompts that actually work.
Wan 2.2 I2V vs Wan 2.1: Same Frame, Same RTX 3090, Different Quality
Ran the same image-to-video test with Wan 2.2's dual-model MoE architecture instead of Wan 2.1: faster and visibly sharper. Real numbers from a local RTX 3090.
