Why would you deliver a video in 1920x964?
I cannot think of a good reason why 1920x964.  It is not uncommon to see 2:1 aspect ratios, which would be 1920x960.  The extra 4 pixels are a mystery, especially because 960 divides by 8 and 16, which make it very JPG friendly.  964 does not divide evenly by 8, either.
