media encoder elapsed time stuck at 1 second

I created a composition in after effects (29.97 fps) thats about 16 seconds long and is 1.9 mb. when I try to export with media encoder using h.264, high bitrate and maximum render quality, the progress and elapsed time get stuck at 1 second. I even tried to wait it out by letting it render overnight but there was no difference the next morning. Ive created several similar videos with the same formats and they have exported just fine. the only difference I can think of in this situation is that I used an extremely large amount of effects compared to my other videos. I would appreciate any help.
