Four upscalers, one upload.

Each model has a different strength. Prices below are for a 10-second, 30 fps clip and come from the same calculation the upscaler uses.

How to upscale a video to 4K

No software to install and no GPU needed. The only decision is which model suits the clip.

  1. 01

    Upload a clip

    Any video up to 60 seconds and 300 MB, or pick one you made in the studio.

  2. 02

    We measure it

    Resolution, frame rate and length are read from the file, so the price is exact before you commit.

  3. 03

    Pick an upscaler

    Choose the model and target size. Each one shows its output resolution and credit cost for this clip.

  4. 04

    Download the sharper version

    The upscaled clip lands in your library. If a job fails, the credits come back automatically.

When upscaling is worth it

Upscaling works best on clips with decent detail that just need more pixels. Here's an honest picture of where it helps.

  1. AI-generated clips

    Most video models render at 480p–1080p. Upscaling makes them hold up on large screens and in 4K edits.

  2. Old or compressed footage

    Phone videos, social downloads and archive clips gain cleaner edges and texture.

  3. Smoother motion

    Topaz and the ByteDance Upscaler can also output 60 fps for silkier movement.

  4. What it can't do

    Upscalers add plausible detail; they can't recover a face that's a few blurry pixels or fix heavy motion blur.

Questions, answered

Yes. SeedVR2 and the ByteDance Upscaler can output 4K directly, and Topaz or FlashVSR can upscale 2× or 4×. Output is capped at about 4096×2304.

Yes. Any of the four upscalers can take a 480p clip to 1080p or higher. Very soft sources look best with SeedVR2, which restores texture.

Topaz for natural, sharp detail and optional 60 fps. SeedVR2 for soft, compressed or AI-made clips that need texture restored. ByteDance Upscaler for the lowest cost to 1080p, 2K or 4K. FlashVSR for quick, cheap 2× or 4× passes that keep the original audio.

Usually a few minutes for a short clip; longer clips and 4K output take longer. You can leave the page; the result appears in your library.

It depends on the model, the clip's length and the output size. You see the exact credit cost for your clip before starting; the table above shows examples. Failed jobs are refunded.

Up to 60 seconds per clip and 300 MB.

The model looks at each frame and its neighbors, predicts the missing detail at the higher resolution, and keeps it consistent from frame to frame so it doesn't flicker.
