This is such a reoccurring question, I've always wanted to make a FAQ about this where we can point to. There are quite a few possibilities and it depends on the system and case which one is the best for you.
A) inside GEM You can record the GEM window inside GEM with pix_record and pix_snap. This is the cleanest and cross platform solution, because it doesn't require additional soft- or hardware. You can also render things slower than realtime, while making sure to save every frame.
B) outside of GEM, but inside the computer Use a screen capturing software, such as Vokoscreen, simplescreenrecorder, RecordMyDesktop or a broadcasting solution like OBS to capture the GEM window and save it in a file.
C) outside of the computer You can display the Gem output on an external monitor and record the output with a hardware device that captures HDMI or DVI. Expensive, but if the former solutions are not viable, then it's the only way. For example you have a live performance with audio and your computer is on its limits CPU wise, so it would crash or crackle if you would run A) or B).

Hi dear list,
I know that Gem's OpenGL output is not primarily designed to be captured into a video file but am wondering what are the best practices by the list members to create a movie file from a Gem window's output?
Thank you for all ideas! P
