## What Jasna does
- Finds mosaics in a video and restores them. The rest of the picture is not
 touched.
- Two restoration models: fast **BasicVSR++** (free) and slow but more
 detailed **LTX** (for supporters, NVIDIA only).
- Restores only the parts you choose, with a preview, in the **Segment
 Editor**.
- Works with VR180 videos and still images (SD 1.5, for supporters).
- Lets you watch a video restored live in the **Video Player**, without making
 a file.
## What you need
- **NVIDIA** GTX 16-series / RTX 20-series or newer, with a recent driver
 (610+ on Windows, 580+ on Linux). GTX 10-series and older don't work.
- Or **AMD** Radeon RX 7000/9000 (experimental).
- A folder on a local disk, with no Chinese, Japanese, accented or other
 non-English characters in its path.
 More details 
- NVIDIA: your GPU needs compute capability 7.5 or higher in NVIDIA's
 GPU table.
- AMD: a GPU supported by ROCm (Radeon RX 7000/9000, Radeon 780M/760M/740M,
 Ryzen AI). On Windows, AMD Adrenalin driver 26.8.1 or newer. Secondary
 restoration and LTX are NVIDIA only.
- Disk format: NTFS on Windows; ext4, Btrfs, XFS or ZFS on Linux. Network disks
 are not supported. Use an SSD; on a hard disk (HDD) Jasna starts and loads
 models slowly.
- LTX needs an NVIDIA RTX GPU, at least 8 GB VRAM and 16 GB RAM. See
 What LTX needs.
## Quick start
1. Download the release for your system and GPU.
2. Unpack it into a folder with no Chinese, Japanese, accented or other
 non-English characters in the path.
3. Start the app:
 - Windows: double-click `jasna.exe`.
 - Linux NVIDIA: run the `jasna` file.
 - Linux AMD: run `run_jasna_amd.sh`.
4. Add a video, choose settings and click the **▶** button at the bottom.
**Your first job is slow.** On NVIDIA, Jasna first prepares the models for
your exact GPU. This takes about **15–60 minutes**, only once. Close other
apps and don't use the PC during this time. When you update Jasna, copy the
`model_weights` folder to the new version, so you don't wait again.
Every setting has a tooltip: move the mouse over the ⓘ icon. Out of GPU
memory (VRAM)? Lower **Max Clip Size**, for example from `90` to `60`. See
Tuning.
## Help and community
- App guide: the queue, presets, output names, the Video
 Player and activation.
- SLS Discord: examples, help and settings.
 Jasna has a new channel;
 older posts stay in the old channel (archived).
