Before and after video enhancement

Step by step

  • Download your finished video from Kling AI 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 it costs

One credit covers 30 seconds of video in Full HD, rounded up. 4K costs double. A 10 second clip is 1 credit in Full HD and 2 in 4K. Packs start at $9 for 10 credits, and the credits never expire.

What upscaling can and cannot do

  • It sharpens soft video, cleans noise and restores faces
  • It makes a 720p or 1080p clip look crisper on a large screen
  • It cannot remove a watermark. If your clip has one, it stays, and it is sharpened with the rest
  • It cannot invent detail that is not there, so the result depends on the source clip

Try it on a short clip first

Your free signup credit enhances a clip of up to 10 seconds, with a watermark. It is a quick way to see the difference before you buy a pack.

Going the other way

If you want to make the video itself in the same place, Create makes it from a sentence or a photo and enhances it automatically.
