Just made this short video while experimenting with adobe after effects. It was originally supposed to be 17 seconds long but my computer would freeze during rendering so i shortend it to 4. I feel like im doing something wrong. the video doesn't have very good quality and this was shot in 720p. Is there something else your supposed to do after sending to render queue and rendering? Here is my comp settings. Also it renders without sound. What am i doing wrong?
