How to Upscale AI-Generated Videos to 4K (Without Losing Quality)

Most AI video models generate at moderate resolutions — typically 720p to 1080p. This is a limitation of the generation process, which prioritizes motion quality and coherence over raw resolution.

For professional use — YouTube, client work, presentations — you need crisp 4K output. AI video upscaling bridges this gap by intelligently enhancing resolution while preserving the motion and detail from the original generation.

1. Generate your video in the Video Lab using your preferred model 2. Download or send directly to the Video Upscaler 3. Upload to Video Upscale and select your target resolution 4. Process — the AI enhances frame-by-frame while maintaining temporal consistency 5. Download your 4K result

The upscaler handles the hard part: ensuring that enhancement is consistent across all frames so there's no flickering, ghosting, or frame-to-frame inconsistency.

Start with the best generation you can: Upscaling amplifies both quality and flaws. Generate the best video you can first, then upscale.

Use the right model upstream: Higher-quality video models (Veo 3.1, Sora 2 Pro) produce cleaner output that upscales better.

Check for artifacts before upscaling: If the original video has glitches or inconsistencies, fix them at the generation stage by adjusting your prompt or trying a different model.

Combine with the full workflow: Image Lab (generate still) → Video Lab (animate) → Video Upscale (enhance to 4K) is the complete pipeline for professional-quality output.
