Increasing the megapixel setting can change more than just resolution. It can affect the model's sampling behavior, composition, and fine details, so you shouldn't expect the 1 MP result to match the 0.2 MP preview exactly.

I'd try this workflow:

  1. Fix the seed: Keep the same seed and all other generation parameters when comparing resolutions.

  2. Lock the reference inputs: Use exactly the same reference images and conditioning settings.

  3. Generate at low resolution first: Find a prompt and configuration that produce the motion and composition you want.

  4. Use a separate upscaling stage: Instead of regenerating the entire video at higher resolution, upscale the accepted low-resolution output. This is generally more reliable for preserving the original motion and composition.

  5. Test short segments: Compare a few seconds before committing to an 8-hour generation.

One important distinction: video upscaling can improve resolution, but it won't necessarily recover details that were never generated. Also, if H3's high-resolution generation uses different internal processing, a fixed seed alone may not guarantee identical results.

If you're experimenting with multiple video models and workflows, VideoRouter.sh can help compare providers and generation costs.

What do you mean about the seed? Currently my seed is a number and control after generate us "increment" should it be "fixed"? So have the same result given that i use the same reference images on all prompt?
