So basically, I tried to render in After Effects as well, but it said "After effects error: Motion Tile cannot allocate a buffer larger than 30000 pixels in either dimension. (516) (25::56) So, right now I'm not even able to render my project... Media Encoder says "Failed" and Render Queue says "After effects error: Motion tile etc. Please help!! !
Nobody can tell you anything without exact system info or other technical details liek comp settings, render settings, footage used, effects in the comp and ultimately what you do to make the Motion Tile effect go *kaboom*.
