Show HN: A zero-lag, scriptable video filter (RVM,Python,OpenCV,OpenGL,Spout2)

A single indie developer released CamFilterGpu, a zero-lag, GPU-accelerated video filter app with RVM-AI segmentation, background removal, and custom filter pipelines, priced at $2.45/month after a 14-day free beta. The app integrates with OBS, Zoom, and Discord, offering features like 3D OpenGL windows and fine color grading that the developer claims are unavailable or behind paywalls in competitors like Manycam or Camo Studio. The beta is available for download with no payment or admin required, and the developer plans to add 4K, multi-cam, and VR support based on community interest.

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)

  • 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)

Download here: CamFilterGpu Installer (no card/pay, no admin needed, portable). 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.

Email for any questions: support@perfunct.com

Cheers! And have fun.
