My video keeps glitching when I try to render it in Media encoder

Is there a way I can stop the glitches. When I try to render the video stuff disappears, part of the screen turns blue, some frames repeat and are faded over the previous frame etc,

My first guess, you have a corrupted MP4 as a source file in your composition. Without workflow, comp, OS, AE version, and system details, that's about all I can think of.

Start by checking your hardware acceleration settings and update your system's graphics driver. For anything beyond that indeed much more info is required as per @Rick Gerard's reply.
