There are two types of motherboard for that model. One has only UMA or integrated video and one has switchable discrete video. If your BIOS and device manager is not showing an AMD Radeon video card then you have just the Intel HD4000 series integrated video.
The HD4000 should have no problem with full HD full screen MP4 playback assuming you have the right drivers and video codecs installed. You say that some full HD videos play OK and others not? What video player are you using? Is there any common feature to the ones that play OK and those that do not?
To answer, no you cannot change video memory allocation. That is done automatically and there is no adjustment. Plenty of video memory is available so that is not the problem. No there is no way to upgrade the video chip without also changing out the motherboard, which would be very costly. 16 gigs of RAM would not alter the video performance.

Open the memory door on the bottom (service door) and under the memory chips the motherboard part number should be lithoed to the motherboard. We can take that part number and check the features of that motherboard. I am about 99% certain you have the Intel video only model.
