InfiniteZoom-Mochi

Fine-Tuning Mochi Text-to-Video: InfiniteZoom-Mochi

This project demonstrates the fine-tuning of the Mochi Text-to-Video model using a LoRA (Low-Rank Adaptation) approach, focusing on the infinite zoom art style.

Training Details

• Model Base: genmo/mochi-1-preview
• Fine-Tuning Dataset: 23 short video clips of infinite zoom art style, and .txt descriptions
• Training Hardware: H100 GPU
• Training Duration: 2h

   prompts:
      - Human fingers pinching to zoom on an infinite zoom canvas, a vast desert landscape stretches into the horizon. At the center, a giant hourglass sits, its glass exterior glinting in the sunlight. The zoom begins within the hourglass, revealing cascading grains of sand, each grain transitioning into a crystalline snowflake, leading to a frozen tundra as the scene deepens further.
      - Human fingers pinching to zoom on an infinite zoom canvas, a colossal tree rises from a lush forest, its bark covered with intricate carvings of stories. The zoom focuses on one carving, which transforms into a vibrant painting of a village. Zooming further, the village reveals bustling streets, where a single doorway becomes the entry to a glowing cosmos.
      - Human fingers pinching to zoom on an infinite zoom canvas, a tranquil ocean surface reflects the twilight sky. The zoom begins within a whirlpool, diving into vibrant coral reefs teeming with marine life. A single pearl on the ocean floor becomes the focus, transitioning into a marble palace with intricate golden inlays as the zoom continues seamlessly.
      - Human fingers pinching to zoom on an infinite zoom canvas, a glowing campfire crackles in a dense, dark forest. The zoom begins in the heart of the fire, revealing swirling embers that transition into galaxies of stars. The zoom then centers on a lone star, which transforms into a lantern hanging in a cozy mountain cabin, seamlessly revealing new layers.
      - Human fingers pinching to zoom on an infinite zoom canvas, a detailed cityscape at night, illuminated by neon lights and bustling with activity. The zoom focuses on a lit billboard advertising a soda can, transitioning into the sparkling surface of the liquid. As the zoom deepens, microscopic bubbles transform into entire ecosystems of floating islands within the soda.
