LUT 64

Simulates a broadcast BT2020 HDR signal in nv12 rec709 color space.

OBS Hogwarts LUT 64

🎮 **No more color distortion in HDR game live streaming! **

Have you ever been troubled by the fact that when live streaming HDR games on Twitch and other platforms, the colors of the screen become pale and overexposed? This mod is for you! It is a LUT file that cleverly maps the color space of HDR games to a standard color space suitable for live streaming, allowing your audience to see an almost authentic game image.

🚀 Quick Start Guide

• **Download and install OBS Studio**.
• Add **HDR video source** and zoom out.
• Set the HDR video source property to **rec601 full**.
• In OBS advanced video settings, select **rec709 full**.
• Finally, add the downloaded **.cube LUT file** as a filter to your HDR video source.

Done! Your live stream should now have much more natural colors.

🧠 Module principle and value

The core of this mod is a **LUT (Lookup Table) image file**. What it does is:

• **Color Space Conversion**: "Wrap" the rec601 color space of the game output into the wider BT2020 dark gamut.
• **Live Broadcast Adaptation**: At the same time, the output is the rec709 video color space widely supported by the live broadcast platform.

**Why is this important? **

Currently, the video encoding (such as H.264) of mainstream live streaming platforms (such as Twitch) does not support true HDR color space broadcasting. If you capture and output the HDR signal directly, the viewer will see a severely distorted picture.

Although OBS provides some HDR encoding options (such as P010 PQ2100), they consume **double the encoding resources** and are not friendly to the bandwidth of the host and the audience.

Therefore, this LUT solution provides a compromise between high performance and high compatibility, allowing you to live broadcast in the standard NV12 format while retaining the visual charm of HDR games to the greatest extent.

✨ Core Features

• **🎨 Color Fidelity**: Designed to allow viewers to see the game as it originally appeared, rather than a heavily compressed or distorted version.
• **⚡ Resource-friendly**: Compared with true HDR encoding, the consumption of encoder and network bandwidth is greatly reduced.
• **🛠️Widely Applicable**: Although tuned for Hogwarts Legacy, it is theoretically suitable for any software or game source that supports LUT filters.
• **🎯 Precision Tuning**: This is the result of months of study, testing and adjustment by the author, aiming to solve a live broadcast pain point that many people ignore.

💡 Usage suggestions

• This mod is mainly for **streamers who share their gaming experience through live broadcast platforms (such as Twitch)**. If you don't stream, this mod may not be of much use to you.
• The author admits that this is not a perfect 4:4:4 lossless solution, but it is currently a **practical solution** that balances effects and performance.
• If you are also suffering from the color problem of HDR live broadcast, you might as well give it a try, it may completely change the quality of your live broadcast!
