Acid Cam is an Open Source project I initially began working on back in 2011. The first version of the program was written in Objective-C and worked with webcams only. The version of Acid Cam this document describes in the 2.0 series, which was rewritten from scratch in C++ with the macOS user interface being Objective-C++. Acid Cam distorts video to create art. It is designed to be used with other software (Syphon) or on its own. There are multiple versions of the program for macOS, Linux, and Windows, as well as a command-line version of the program. The program also has a live webcam feature. If you wish to use this feature, you should use a lower resolution and not stack up to many filters. The majority of the time, this program is more useful in video mode, where it can process multiple filters in up to 2160p 4K resolution.

Some important Notes:

To be able to use all the filters in this app, your system should have at least 8 GB of Ram for 1080p video. For 4K higher Ram is recommended, but you can set the Max Stored Frames based on the resolution you are doing and when it is reached it will release the frames. On my system for 2160p video when using something like a Random filter I set it to 400 frames for my system with 32 GB ram. You can set it lower based on your system ram level It is in the preferences window. Some filters require more than the default amount of allocated frames. Usually these have the name 640 or 720 in the title. If you are running with enough Ram, please set the require frame limit before starting your session!

The video Acid Cam outputs is saved at a very high bitrate. Sometimes you will need to lower the bitrate to view the video with a video player. I usually import the video into Final Cut Pro X then lower the bitrate by exporting it as H.264. Another program you could use would be Handbrake. The following image is of MediaInfo on a 4K video created with Acid Cam. The overall bitrate is very high.

or use FFMPEG like this:

$ ffmpeg -i "input.file.mp4" -c:v libx265 -tag:v hvc1 -crf 22 output.file.mp4

This version shares some code with libacidcam, so sometimes, when I update the parts that are shared show up in both projects. libacidcam uses C++/OpenCV and Autotools, and this macOS program uses Objective-C++/Cocoa/OpenCV and Xcode This project was created in hopes of providing some entertainment, or for the Glitch artist to give you an image/video to use with other tools. I call the art that I create with Acid Cam "Acid Glitch," but you can call it whatever you want. It is just meant to be a tool to use with other programs to help aid in the creation of artistic images/videos. Acid Cam's effects are created by using Acid Cam 'filters', or pieces of code that distort an image and can be combined to produce some exciting effects. The project currently has over 2,000 filters to mix and match and supports output as MPEG-4 or H.264. 5.20.19: I upgraded the program's OpenCV library files to version 3.4.6, and some of it has changed. The OpenCV header files included now have a warning from possible misuse of a comma. Also, I am on Mojave, and the GUI scales windows up and down automatically while still having a resolution of 5K. The problem is OpenCV has code that resizes the window, and it is not sized correctly. I will work on fixing these issues, but the version of OpenCV I compiled contains OpenCL support. Just on my computer with the new libraries, it moves much faster. I can confirm Acid Cam works with Elgato Camlink 4K. With this device, you can use any HDMI device as a Webcam source for Acid Cam. Combined with OBS, you can live stream your self filtering video games/yourself on your camcorder in real-time with audio.
