What do you want to do?

3 use cases

  • Render a first-person walkthrough MP4 from one image

    Run the Preview v1 pipeline on a first-frame image to get a clean MP4 with motion-driven video and sound.

    View prompt
    In the HelixWorld repo (NoizAI/HelixWorld), set up the Preview v1 environment as described in the README, then run ./run.sh with --image <path to first-frame PNG> and --output-dir outputs/demo. Expect a clean MP4 under outputs/demo, and verify that the file exists and that ffprobe reports a video stream and an audio stream.

  • Score whether generated sound follows camera motion

    Use the HelixBench dataset to test if synthesized sound fields track dynamic viewpoint motion.

    View prompt
    Using the NoizAI/Helixbench dataset on Hugging Face and the HelixWorld repo (NoizAI/HelixWorld), generate outputs for the dataset items into <output folder> and compare stereo panning with camera motion for each clip. Expect a results table with one row per clip; verify that the row count matches the number of dataset items.

  • Walk through a Helix World scene in the browser

    Open the hosted demo to hear how sound changes as you move and turn, with no local setup.

    View prompt
    Open https://helixworld.org/ in a browser, move forward and turn in one scene from the HelixWorld project (NoizAI/HelixWorld), and report whether the sound changes with the viewpoint. Expect a short written note; verify that the note states the scene name and the observed sound changes.

How to use Helix World

  1. Check you have what it needs: Linux with Python 3.11 and CUDA 12.x; NVIDIA GPU, 80 GB VRAM recommended (a reviewed BF16 single-GPU run uses about 70 GB); System ffmpeg and ffprobe installed.
  2. Open NoizAI/HelixWorld on GitHub and read the README and license.
  3. git clone https://github.com/NoizAI/HelixWorld.git
  4. cd HelixWorld
  5. conda create -n helixworld-preview python=3.11 -y
  6. conda activate helixworld-preview

These steps come from our top use case, Render a first-person walkthrough MP4 from one image, which also has a copy-paste agent prompt.
