# Increase Resolution - up to 8K

`POST /increase_resolution`

[**Try out this capability in Bria's sandbox**](https://platform.bria.ai/video-editing/video-increase-resolution)


**Description**
Initiates an asynchronous resolution upscaling job for a video.

**Upscales up to 8K output!**


Response behavior:

- Returns HTTP 202 with `request_id` and `status_url`

- Check job status by polling `status_url` or by calling the [Status Service](https://docs.bria.ai/status) with the `request_id` until a terminal status is returned


Supported input containers:

- .mp4, .mov, .webm, .avi, .gif


Supported input codecs:

- H.264, H.265 (HEVC), VP9, AV1, PhotoJPEG


Input attributes preserved in output:

- Aspect Ratio

- Frame Rate

- Color Bit Depth

- Audio if present

- Transparency if present and supported by the selected output preset


Limits:

- Max input duration: 60 seconds

- Max output resolution: 7680x4320 (8K). If the selected `desired_increase` would exceed this limit the server returns 422 Unprocessable Entity.


Encoding:

- Bitrate is adjusted automatically to match the target resolution to preserve quality.
