Take a close look at the fonts used in the titles around that point in the timeline (20-30%). There have been numerous similar cases where the font used turned out to be the culprit.
My user indicates that he hasn't used a lot of text in the project, but he also cannot be sure because the development of the project has spanned a couple of weeks. He is going to continue to work on the project, but I'm going to have him change the font to something a little more "vanilla" to see if that affects the rendering issue.
I will let you know the outcome as soon as I have one.
If the project have captured video, this problem can be caused by defective capture. Frames of captured video can have compression problems even not having any apparent defect when they are showed. Since some compressions are inter frames, the compression can have defects during the capture. the funny is, the appearance of those frames can look like normal (since human eye cant see and scan those thousands/millions of pixels one-by-one and detect which one is defective).When you are about to encoding it, or "trancode" it, the change from a defective compressions to a mpg2 DVD for example make the program crash.
If thats the case, u can check in which frame Prem crashes, get the clip to AE and re-export it to a completely diferent format and compression, them replace the Premiere clip by the new one.
