I wanted to make a simple animation of the camera approaching the head, the head losing its pupils, then the eyes glowing. When I looked at the project in rendered view in the layout tab, it worked exactly how I wanted it to. So, I went to the render tab, set the resolution to hdtv 1080p, and chose to export as ffmpeg video, choosing h264 in mp4 as my encoding preset. FYI, I am using cycles rendering engine here, and have tried it with eevee and gotten the same problem. Once I hit render, it stayed on the first frame for about 30 minutes(remember, this is a very simple animation, the surfaces aren't smoothed out very well, there isn't a lot going on), then blender crashed. This happened several more times after I restarted blender and my computer. While CPU usage increased, the render window didn't show any data, and just showed a blank checkerboard background, with no tiles rendering or anything. Seeing other questions on this site with similar problems, I turned off sequencer in the post-processing settings. That changed nothing about the render window. What's wrong? Let me know if you need more info, here's the blend file
Thanks!
