Deep Dive: Fixing AI Video Faces via Resolution & Outpainting
spiderofmars · reddit · 2026-08-18
Detailed analysis of fixing facial detail loss in AI video generation with specific solutions.
- Resolution First: Higher render resolution is key to base quality, especially for full-body or small face shots.
- Vertical Advantage: Vertical resolution (e.g., 768x1344 vs 1344x768) greatly increases facial detail in the same render time.
- Upscaling Workflow: Render at 1088x1920 then downscale back to 1280x720 timeline.
- Background Outpainting: Use LTX model for outpainting backgrounds, feathering the original subject back in to fix composition.
