How to Upscale Images and Footage for 4K After Effects Projects

Upscale images and footage for 4K After Effects projects by using AI to increase source resolution before final compositing. This helps when client assets, generated images, archived footage, or downloaded references are too small for a 4K timeline.

Prerequisites

Check the source resolution, delivery resolution, and how large the asset appears on screen. Not every asset needs 4K source resolution if it stays small in the frame.

Step-by-step workflow

1. Identify the low-resolution asset in your After Effects project.
2. Decide whether you need image upscaling or video upscaling.
3. Open Ziframe and choose image upscaling or video upscaling.
4. Pick the smallest scale factor that fits the comp.
5. Import the upscaled result.
6. Replace the low-resolution layer.
7. Review edges, grain, and detail at full resolution.

Recommended Ziframe models

Use image-upscale models for still assets and video-upscale models for footage. Pair upscaling with color correction and grain matching inside After Effects.

Common mistakes

Do not upscale everything by default. Upscaling costs time and credits, and unnecessary artificial detail can make an otherwise clean composition look inconsistent.

FAQ

Should I upscale before or after compositing?

Upscale source assets before compositing when the original is too small. Upscale final clips only when the whole rendered shot needs more resolution.

Can AI upscaling fix bad footage?

AI upscaling can improve perceived detail, but it cannot fully recover missing focus, motion blur, or heavy compression artifacts.

What upscale factor should I use?

Use the smallest factor that reaches your delivery size. Overscaling can create artificial detail that is harder to grade.
