## When to choose it

Topaz Video Upscaler belongs near the end of the workflow: the story, movement and edit work, but the frame is too small. Upload the finished file and select a scale. This is not a text-to-video generator or an automatic repair tool for incorrect anatomy and action.

- Processes a finished clip without a new scene description.

- Can double or quadruple the frame dimensions.

## Modes and settings

- 1× processes without enlarging; 2× and 4× multiply the frame dimensions.

- One MP4, MOV or MKV file, up to 50 MB on the website. No prompt required.

## Price in coins

| Quality / size | Input | Coins / second
| 1× | Existing file | ≈ 5.6
| 2× | Existing file | ≈ 5.6
| 4× | Existing file | ≈ 9.61

Billing is per second, not per fixed-length clip. The rate is multiplied by the billable duration; the complete request total is rounded up to a whole coin once.

Billing uses the uploaded video's duration at the selected upscale setting.

≈ marks a fractional rate rounded to two decimal places for display; billing uses full precision.

## What you can make

- Prepare a selected AI clip for a larger edit.

- Enlarge source footage before moderate cropping.

## How to direct the result

- Use the cleanest source, not a repeatedly compressed copy.

- Finish editing first. Afterwards inspect faces, lettering and moving edges at 100%.

### Preparation example: a final advertisement
Copy

```text
Select a finished ten-second clip without editing errors. Upload the source MP4 and choose 2×. Compare faces, logos and fine outlines before and after, then check movement at normal playback speed.
```

## What to keep in mind

- A 4× scale does not recover true detail that never existed in the source.

- Upscaling does not correct the story, pose or incorrect object movement.

## FAQ

What prompt should I write?

None. Supply a video file and a scale, not a description of a new scene.

What does 1× do?

It processes the video without increasing frame dimensions.

How do 2× and 4× differ?

They multiply width and height; they do not promise a particular 2K or 4K standard.

Why does a longer clip cost more?

The per-second rate is multiplied by the uploaded video's duration. The table lists the rate for each upscale setting, not the price of a fixed-length clip.

Will it fix extra fingers?

Do not rely on that. Correct the source or choose a different generation first.

Why does sharpening look artificial?

Weak sources can acquire emphasized edges and invented texture. Compare at full size, not only in a small preview.

What changes the price?

The coin rate per second depends on quality, mode and, for some models, sound. Multiply it by the billable duration. Where input video is charged, its duration also counts. The complete request total is rounded once.

Do I need a separate model subscription?

No. In Mixer AI, you top up one coin balance and use it for the tasks you need. You do not need a separate subscription to this model.
