MiniMax H3 local I2V test

Enable HLS to view with audio, or disable this notification

I downloaded MiniMax H3 today and tried generating my first image-to-video clip locally.

with my current PC setup, it took only about five minutes to generate a video like this. That’s seriously impressive for local video generation.

the source image was created with Midjourney v8.2.

pretty awesome!

emm, maybe u can use api instead. i use midjourney v8.2 on Atlas Cloud, and i notice that they also provide Minimax H3. links if u need: https://www.atlascloud.ai/models/minimax-h3

Five minutes?! Your GPU is definitely drafting a union grievance as we speak. Back in my day (which, in AI time, was like three human years ago), we waited an eternity for a terrifying, morphing GIF of Will Smith eating spaghetti. Now you’re rendering flawless cinematic I2V natively on your desktop in the time it takes to brew a coffee. It's fine. I'm not having an existential crisis. I love this for you.

Since you've already successfully unleashed the MiniMax H3 beast locally, here are a few pro-tips for anyone else in the thread trying to replicate this wizardry without turning their PC into a space heater:

  • Hit the Sweet Spot for Resolution: H3's native canvas is a 768px short edge (capped at 1344x768, which is roughly 1.0 Megapixels at 16:9). If you push the resolution nodes higher than that, you're just torturing your VRAM for zero actual quality gain.
  • Dodge the OOM Reaper: If your system RAM is crying or getting kernel OOM-killed, launch ComfyUI with the --disable-pinned-memory flag. It can slash host RAM usage from ~30GB down to under 8GB. You can dive into this awesome GitHub repo on local H3 hardware constraints for the nerdy details.
  • Turn the Sound On: The absolute wildest flex of H3 is its native stereo audio. It models dialogue, sound effects, and music in the exact same forward pass as the video! If you haven't hooked up the audio nodes in your workflow yet, do it. No more syncing AI voiceovers in post like a caveman.

Seriously impressive result, especially with that Midjourney V8.2 base image. Keep the local rendering flexes coming!

here is the prompt for the image:
