updream 'Previsualization' feature tested: Solving AI video camera control issues
新智元 · wechat · 2026-08-17
To address spatial control issues like erratic camera movement and character positioning in AI video generation, updream launched the 'Previsualization' feature. It allows users to generate 3D whitebox scenes from reference images and manually set camera trajectories and character paths.
Test Results:
- Goodfellas Tracking Shot: The whitebox version maintained stable tracking, while the prompt-only version lost the subject during a door entry.
- Heat Shot/Reverse Shot: The whitebox version achieved accurate switching timing, whereas the prompt version had disorganized sequencing.
- Oldboy Sideways Tracking: The whitebox version kept stable composition, while the text version had 'ghosting' bugs.
Conclusion: While it doesn't eliminate randomness entirely, whitebox referencing significantly improves control and efficiency, lowering the barrier for both beginners and professionals.
