## How to restore mosaics in a video with the Jasna app with Jasna

Repo: [Kruk2/jasna](https://github.com/Kruk2/jasna) | Difficulty: Beginner | Time: 1 hour | Basis: From the README

Use the desktop app to restore mosaics in a video on your own GPU, using the free BasicVSR++ model.

**Who it is for:** A video owner with a supported GPU who has a mosaiced video file and wants a restored copy without writing code.

**The problem:** Mosaics cover parts of a video and the original picture is hidden.

**The outcome:** A restored video file, with only the mosaic areas changed, saved from the app queue.

### Steps

1. Download the release for your system and GPU from GitHub only.
2. Unpack it into a folder whose path has no Chinese, Japanese, accented or other non-English characters.
3. Start the app: double-click `jasna.exe` on Windows, or run `jasna` on Linux NVIDIA.
4. Add your video, choose settings (move the mouse over the ⓘ icon for a tooltip) and click the ▶ button.
5. Wait for the first job, which prepares the models for your GPU in about 15 to 60 minutes, then keep `model_weights` when you update.

### Prompt to paste into your agent

```text
Using the Jasna repo at Kruk2/jasna, download the release for <GPU and OS> from GitHub, unpack it to <local folder path with ASCII-only characters>, and start the app. Expected output: a restored video file from <input video path>. Verify that the output file plays and that only the mosaic areas differ from the original.
```

### Caveat

The first job is slow on NVIDIA because models are prepared for your exact GPU, and LTX and supporter models need a License code.

Risk, remote script: Only download Jasna from GitHub, because other sellers' files can run hidden code on your PC.

Dual-use notice: only use this on software, sites and systems you own or are authorized to test.

## How to batch restore a folder of videos from the command line with Jasna

Repo: [Kruk2/jasna](https://github.com/Kruk2/jasna) | Difficulty: Intermediate | Time: 1 hour | Basis: From the README

Run Jasna on a whole input folder in one command and save the results to an output folder.

**Who it is for:** A person with many mosaiced clips who wants them processed unattended from a terminal.

**The problem:** Restoring many files one by one in the app takes a lot of manual work.

**The outcome:** An output folder with restored files, one per input file.

### Steps

1. Open a terminal in the folder where the Jasna release is unpacked. (inferred, check the README)
2. Check the options with `jasna --help`.
3. Run `jasna --input input_folder --output output_folder`.
4. Wait for the run to finish and check the output folder.
5. Read the CLI reference in docs/en/cli.md for other options.

### Prompt to paste into your agent

```text
Using the Jasna repo at Kruk2/jasna, run `jasna --input <input folder> --output <output folder>` on the Jasna release. Expected output: one restored file in <output folder> for each input file. Verify that the number of output files matches the number of inputs and that each plays.
```

### Caveat

The README says the command line does not cover the Video Player, LTX seed previews, mask suggestions or interactive image mode.

## How to restore a single still image from the command line with Jasna

Repo: [Kruk2/jasna](https://github.com/Kruk2/jasna) | Difficulty: Intermediate | Time: 1 hour | Basis: From the README

Restore one image file with a single command and save the result as a new file.

**Who it is for:** A photo owner with one mosaiced picture who wants a restored copy quickly.

**The problem:** A still image has mosaics that hide details, and the original file should stay unchanged.

**The outcome:** A restored image file saved at the output path you choose.

### Steps

1. Open a terminal in the folder where the Jasna release is unpacked. (inferred, check the README)
2. Run `jasna --input photo.png --output restored.png`.
3. Open restored.png and compare it with photo.png.
4. Check the README for which model your image run uses, since SD 1.5 for still images is a supporter model.

### Prompt to paste into your agent

```text
Using the Jasna repo at Kruk2/jasna, run `jasna --input <image path> --output <output image path>`. Expected output: a restored image at <output image path>. Verify that the file opens and that the mosaic area looks different from the original while the rest of the picture is unchanged.
```

### Caveat

The README marks SD 1.5 for still images as an experimental supporter model, so image quality and model access depend on a License code.

## How to restore only chosen segments of a video with Jasna

Repo: [Kruk2/jasna](https://github.com/Kruk2/jasna) | Difficulty: Beginner | Time: 1 hour | Basis: From the README

Use the Segment Editor to pick the parts of a video to restore and preview them before the run.

**Who it is for:** A video owner whose mosaics appear only in a few scenes and who wants to save processing time and keep the rest untouched.

**The problem:** Restoring a full long video wastes time when only some scenes have mosaics.

**The outcome:** A restored video where only the selected parts were processed, with a preview checked first.

### Steps

1. Start the Jasna app and add your video.
2. Open the Segment Editor and select the parts you want to restore.
3. Preview the selected parts before starting the job.
4. Click the ▶ button to run the queue.
5. Read docs/en/segments.md for the mosaic scan and LTX options.

### Prompt to paste into your agent

```text
Using the Jasna repo at Kruk2/jasna, open <input video path> in the Segment Editor, select the segments containing mosaics, and run the queue. Expected output: a restored video with only those segments changed. Verify by comparing a selected segment and an unselected segment with the original.
```

### Caveat

The README describes LTX as useful only for big mosaics in the segment workflow, and LTX needs an NVIDIA RTX GPU with at least 8 GB VRAM and 16 GB RAM.
