Multi Capture to video file Maya Playbast

#1

Here is a script from GitHub which can capture all four viewports in Maya and creates image sequence.

Is there anyway to capture all the viewports and produce as a video file instead of image sequence

or

Is there anyway to convert the image sequences to a video file from inside maya itself, so that it creates the image sequence first and then combine all the images to a video file from inside maya, and not with the help any other softwares.

Here is the code for multicapture.

I know you said you were looking for a solution without other software however you should really look into ffmepg. It has a command-line that you can pass sequences of images to produce a quad video. The syntax can be a bit daunting but once you get the formatting correct it does work pretty well for this.
