When you execute the following code in maya, playblast will be exported as uncompressed AVI and the AVI will be converted to mp4 immediately. AVI will be deleted automatically after conversion to mp4.

# -*- coding: utf-8 -*-

import maya.cmds as cmds
import ffmpeg
import os

#Specifying the export destination
mp4 = "D:/test.mp4"
avi = mp4.replace("mp4", "avi")
#Export play blast
cmds.playblast(fp=4, offScreen=1,
               clearCache=1, format='avi', sequenceTime=0,
               showOrnaments=0, percent=100,
               filename=avi, viewer=0,
               compression="None", quality=100, widthHeight=(500, 500),
               fo=1)
#Convert AVI to mp4 using ffmpeg
stream = ffmpeg.input(avi)
stream = ffmpeg.output(stream, mp4, pix_fmt='yuv420p', vcodec='libx264')
stream = ffmpeg.overwrite_output(stream)
ffmpeg.run(stream)
#Delete AVI
os.remove(avi)

error

In my environment, I got the following error when reading ffmpeg. Apparently, the cause is that the file under lib2to3 of python27.zip cannot be opened (cannot be decompressed?). It seems that you can download lib2to3 from python github, so download it C: \ Program Files \ Autodesk \ Maya version \ Python \ Lib \ site-packages After moving to, it started to work.
