Drag and drop an LUT PNG of your choice under the Settings pane. Installation & Use Instructions Place the 'LUT.qtz' file under CamTwist>Effects Open CamTwist, Select LUT under Effects. You can find the Quartz Composer Effect file here: Ĭredit to Github user YuAo for Apple CoreImage reference code to map the LUT. Ive included a few converted PNGs based on publicly available free LUTs (see credits below). Filter by these if you want a narrower list of alternatives or looking for a specific functionality of CamTwist. CamTwist alternatives are mainly Live Streaming Tools and Services but may also be Face Filter Apps or Screen Recorders. Unsupervised face anti-spoofing using dual cameras based feature matching Annu Int Conf IEEE Eng Med Biol Soc. Other interesting Windows alternatives to CamTwist are Man圜am, SplitCam, Snap Camera and Loola TV. Most current face anti-spoofing algorithms are based on feature extraction and machine learning. Thus, I spent the day searching around and managed to clobber together a CamTwist Effect that allows you to apply a LUT's (via a PNG converted from CUBE) to your videos. Face anti-spoofing is a crucial part of face recognition system to protect subjects privacy and life safety. However, the Effects are created in Quartz Composer (also deprecated) which don't have a LUT inputs in its Library. Surprisingly, it seemed like CamTwist (which doesn't seem to have been in active development since 2013) is still the most effective and simple broadcasting software for Mac with a virtual cam output. OBS is the standard for streaming and allows you to apply LUT's but lacks virtual cam output for use with Zoom, Hangouts/Meet, Skype etc.

Look-up Tables (LUT's) seem to be the standard today to color-grade in videography so I wanted to figure out how to apply them to my videos.
With all of us doing A LOT more video conferencing these days, I wanted to improve my videos by both connected a real camera (via an HDMI capture card) and applying some color grading to improve the quality (plus add some effects or graphics on occasion). I wasn't sure where to share this, but I figured I would post this in case anyone was trying to do something similar.
