Creating Anaglyph Video with FFMpeg

Creating Anaglyph Video with FFMpeg

In this post, we’ll step through how to create anaglyphic stereoscopic videos using FFMpeg. To create anaglyph imaging, we’ll need to use two camera sources, one left, the other right. These sources will be merged into a single image with red cyan overlaying to create a three dimensional effect using red cyan glasses. I referenced these sites frequently. FFMpeg Documentation – https://ffmpeg.org/documentation.html FFMpeg Stereoscopic Details – https://trac.ffmpeg.org/wiki/Stereoscopic The source video I’ll be demonstrating was shot with two Innovv C1 dashboard…

DeFish Effect with FFMpeg

DeFish Effect with FFMpeg

In this post, we’ll cover how to use FFMpeg to removed the radial effects of a fish eye lens. This distortion is a trade off of wide angle lenses. The wider view also included bends and bows to objects that are in nature straight. FFMpeg has a filter known as “lenscorrection” that will remove most of this distortion, lets begin. As always, split out a segment so you don’t waste time processing excessive amounts of data. ffmpeg -ss 00:00:39 -i…

Color Thresholds and Masking with FFMpeg and ImageMagick

Color Thresholds and Masking with FFMpeg and ImageMagick

I’ve demonstrated how to take videos and convert them into images using FFMpeg in previous posts. In this post, I’ll be using that same process and ImageMagick to create a color threshold effect. The interesting aspect is that all of the processing can be done through the command line. When faces with editing numerous files, scripting is the way to go. The few hours of up front work getting the script right is worth it. You can get on with…
