*Instantly transform* your video. Note there is NO CHANGE in lighting below. All software.

**NOT Vibe-coded.**
- Now with
**video backgrounds!** Loop, zoom & position! (auto saves/loads on restart)
- Load/save/share your own
*custom filters & pipelines.* (many templates provided)
- Precise RVM-AI segmenting controls, tracking, background removal, and fine color grading
- Seamless zero-lag integration with: OBS, Zoom, Discord, etc.
- True OpenGL 3D window! Fast GPU-accelerated (heavily optimized)
**WILD** never-before-seen effects, AND... make your own! (see [Overview Demo](https://youtu.be/qXrLXt0UrxQ?t=293s))

Much more. See the demos (buttons above).

Tracking and fun effects. Amaze your friends :). Fully adjustable solid/transparent backgrounds.

Make your own custom, unique 'look'. Add a snappy logo. 3D objects, more...

Live, independent control of foreground and background levels (remove, color grade, etc.).

- Precise: Use the scroll wheel to fine-tune the sliders. The 'QuickSave' button instantly saves all settings.

- Restart: Exactly where you left off! All settings instantly restore when the App starts.

- Save & load: Make custom settings for different rooms-lights, cameras, or session e.g. Zoom, Discord, etc.

- Easy to use, responsive, compact GUI with quick-save and auto-load upon startup.
- Many functions that are not available
*at all* (or behind expensive paywall) in other Apps like Manycam or Camo Studio.
- Seamless integration with OBS, Zoom, Discord, Slack, etc.

Give it a try!

Download the Beta (Free 14 days, after just $2.45/mo. Early adopters get special bonus!)

(That's less than a cup of coffee these days, and far less than any similar App to my knowledge)

**PLEASE NOTE:** I am a single indie developer/coder, and this is early access *Beta software*.

Your support is **greatly appreciated** and goes to further the development of this App.

NOT vibe-coded. I have already dedicated many months to this effort, at first because *I needed better and quicker/finer*** camera and video-imaging control than OBS or Camo studio.**

Then I started thinking, "Heck, this would be really useful for others..."

And so the journey began. **Improving the custom node/filter editor, 4K, and multi-cam/VR are the next steps if there's enough initial support/interest.**

There will be bugs, even though I've tried to make it as bulletproof as possible.
If something crashes, a window will pop-up with the error report, but the App *should* continue normally when the pop-up is closed.

Submit errors or any issues on the [Discord](https://discord.gg/48YjBFUqzr) and/or [GitHub](https://github.com/CamFilterGpu-Dev/Custom-Filter-Library), and reddit /r/camfiltergpu.

- I have tested dozens of cameras/configs, but some webcams are bizarre and difficult esp. built-in laptop cams. If your webcam (or any cam) is not auto-detected, send an email or post to the Github, and I will fix asap.

Cheers! And have fun.
