Ok I went through the process of upgrading to 10.0d (which seems to play the raw files from the T2i smoother than 10.0a). I attempted to render the file again and after about 6 hours it got to about 37% before giving me the same error.
I discovered late last night I actually did NOT do this project with Mpeg Streamclip. (I saw online that Pro 10 was able to preview the files in realtime.) Therefore, my project file includes the original files from the camera and not intermediate files. Any help as to why my project is not rendering?
*UPDATE*
I wonder if it has anything to do with how I’m rendering the file. I have 60fps/720p video and I was trying to render to mp4 at 30fps. I am trying out rendering to .mov as I saw you advise someone to render in the same format as the original file to get the highest quality. I will let you know if this works. Hoping for the best!
