Why people upscale Runway clips
Runway clips are often a first draft for a bigger project, and the export that arrives is usually smaller than the screen it will be shown on. Upscaling gives an editor more room to crop, zoom and grade without the picture going soft.
Step by step
- Download your finished video from Runway as an MP4.
- Create a BetterVideo account. Your free signup credit lets you try a short clip.
- Upload the video (MP4, MOV or AVI, up to 5 minutes).
- Press Check Video & Cost, then choose Full HD 1080p or 4K Ultra HD.
- Download the enhanced video when it is ready.
What to expect from Runway clips
Runway clips are short, so a typical file is a few seconds long and low in credits to enhance. Free-plan exports may be lower resolution and watermarked, per public reports, so start from the highest quality export your plan allows.
Tips for Runway clips
- Export the highest-quality file your plan allows before you upscale
- If you made several clips for one sequence, upscale them all at the same setting so they match
- Keep the original in case you want to re-enhance later at a different size
What it would cost
A typical Runway clip of about 10 seconds costs 1 credit to enhance in Full HD or 2 credits in 4K, because one credit covers 30 seconds and 4K costs double. Packs start at $9, and the credits never expire.
What upscaling cannot do
- It cannot remove a watermark. If your clip has one, it stays and is sharpened with the rest.
- It cannot invent detail that is not in the clip, so results depend on the source.
- It cannot turn a watermarked free-plan export into a clean one
