Upscaling AI output for broadcast and client delivery

TL;DR

Generate cheap at 720p, pick your best result, then upscale that one winner to 4K. This saves 60–80% vs. generating everything at max resolution. Upscale first, color grade after.

AI models generate at 720p or 1080p. AI upscaling generates new detail that wasn’t in the original — sharper and cleaner than Premiere’s built-in scaling, which just stretches pixels.

When to use this in your workflow

• The smart workflow (generate cheap, upscale your winner): Generate at 720p (cheapest, fastest), run 5–10 variations, pick the best, upscale that one to 4K. Saves 60–80% vs. generating everything at 4K directly.
• Before client delivery or broadcast: Final deliverable requires 4K, UHD, or higher? Run your selected clips through an upscaler before export.
• When Premiere’s scaling isn’t enough: If you’ve ever scaled a 720p clip to fill a 4K sequence and seen the softness — AI upscaling generates actual detail instead of interpolating.
• 2x vs 4x: 2x doubles resolution (720p → 1440p, 1080p → 4K). 4x quadruples it. Use 2x for most needs. 4x is for extreme cases — large-format print or unusually small sources.

Key principle: Upscaling should always be the last step. Pick your best result based on composition, motion, and content first. Upscaling a bad generation doesn’t make it good — it just makes it bigger.

How it works in modelBridge

Filter by the image-to-image category in model search to find upscaling models:

• Clarity Upscaler — general-purpose, good for photographic content
• Aura SR — fast, efficient for batch work
• ESRGAN / Real-ESRGAN — strong on textures and fine detail
• Creative Upscaler — adds creative detail, can enhance AI-generated images significantly

Select your image or screenshot a video frame, choose an upscaler, set the scale factor (2x or 4x), and generate. The result imports directly into your Premiere project.

Upscaling is generally cheap — often under $0.10 per image. The cost preview badge shows the price before you commit.

For video upscaling, some models accept video clips directly and maintain temporal consistency. Check the model’s accepted input type in the specs row.

Quick answers

Should I upscale before or after color grading? Upscale first, then color grade. The upscaler works best on clean, ungraded footage.

How much does upscaling cost? Usually $0.02–$0.10 per image. Much cheaper than generating at high resolution directly.

Can I upscale video, not just images? Some models support video input directly. Others require frame-by-frame processing. Check the model’s input type.

Does 4x always look better than 2x? Not always. 4x on already-decent source can look over-sharpened. Start with 2x.

AI upscaling vs Premiere’s “Set to Frame Size”? Premiere interpolates (blurs to fill). AI upscaling generates new detail. The difference is visible on large displays.
