AI Video Upscaler: Sharpen Low-Res Footage up to 4K
The VdoBloom AI Video Upscaler is an AI tool that increases the resolution and sharpness of existing videos, turning soft, low-resolution footage into crisp HD or 4K output. It uses Topaz AI-powered upscaling technology to reconstruct detail rather than simply stretching pixels.
It is the natural last step in an AI video workflow: generate a clip with any VdoBloom video tool, then upscale it before publishing. It also works on your own footage — old recordings, compressed downloads, or phone videos that need to look clean on a large screen.
How it works
- 1
Upload the video
Add the clip you want to enhance — AI-generated footage or any video file that needs more resolution.
- 2
Choose your target quality
Select the upscale settings for the output resolution you need, up to 4K.
- 3
Let the AI enhance it
Topaz-powered upscaling reconstructs detail frame by frame. Processing typically takes a few minutes.
- 4
Download the upscaled video
Compare against the original and save the high-resolution version.
Frequently asked questions
How is AI upscaling different from just resizing a video?
Standard resizing stretches existing pixels, which makes footage bigger but blurrier. AI upscaling analyzes each frame and generates plausible new detail — edges, textures, fine structure — so the enlarged video actually looks sharper. VdoBloom uses Topaz AI upscaling technology, a widely used engine for this kind of detail reconstruction.
Can I upscale AI-generated videos to 4K?
Yes. Many AI video models output at moderate resolutions, and upscaling is the standard way to prepare those clips for large displays or platform-quality requirements. Generate your clip in any VdoBloom video tool, send it to the upscaler, and download the enhanced version up to 4K.
What kinds of videos benefit most from upscaling?
Footage that is structurally good but resolution-limited benefits most: AI generations, older camera recordings, compressed social media downloads, and screen captures. Heavily corrupted or extremely blurry video can improve too, but the cleaner the source, the better the upscaled result.
Does video upscaling cost credits?
Upscaling, like other VdoBloom generation tools, runs on the platform credit system. The free tier lets you try it out, and paid plans include larger credit allowances for regular enhancement work. See the pricing page for current plans.
