Do you have a graphics card? This is heavy on graphics and a CPU's integrated graphics will give you just about that performance, in my opinion. If you have a graphics card, Windows may not be selecting it for ALMAM Player, which in that case you can go in Windows graphics settings and select the application, manually force discrete processing or use graphics card instead of "Let Windows decide", and that will ensure it's using the graphics card. For the rendering too, it all depends on your graphics card and I just don't see any way possible for someone to render that kind of video on a CPU in a short time.
