PE4 has always been crash-happy on my machine, the specs of which I list:
CPU: Intel Core 2 Duo @2.66GHz
RAM: 4GB DDR2
OS: Win7 x64 service pack
Graphics card: nVidia GeForce GT 520 (2GB)
Harddrive: 1TB (Seagate, I think...could be Western Digital) with 645GB free space
From the threads I've read, I've seen that nVidia cards can sometimes cause problems with Adobe software, so that could be part of the general crash problem. My driver is the latest (updated today, 7/3/13.)
Anyway, I've begun encountering a problem with a 33-minute-long animated film I've been editing in PE4. The movie has a lot of material on the timeline because all the animated video clips were split up with freeze frames in post-production to sync footage with dialog, and then there are a bunch of short sound effect clips on top of that plus music. Total, I have two video tracks and 8 audio tracks. I published the movie as an MPEG to my computer last night and then this afternoon, I burned a few DVDs of the finished project. When I reached a point about 13 minutes into the film, the speakers on my TV emitted a horrid screaching noise that lasted for about two seconds. In the film, a .wmv clip is playing with an ambient sound effects clip and a series of three short, consecutive sound effects for a character knocking on a wood box. (These audio clips are in separate tracks and are not a part of the .wmv file; I added them separately.) I thought perhaps my TV speakers were the problem, but my computer speakers acted the same way. Next I assumed that some glitch had occurred in media encoding and so I closed PE4, reopened, and burned a new disk with the same result. I checked the .mpg file that I exported last night, and the screach was absent from it.
I next tried to examine that specific spot in my timeline, but when I scrolled to it and zoomed in to a level where I could see <1 second long sound clips, the program crashed without mentioning a specific error. The Windows error reporting box popped up and simply informed me that "Adobe PE4 has encountered a problem and needs to close." Sceneline mode doesn't crash at that point, but timeline does. The only thing I can conclude is that somehow files on the timeline got corrupted between last night and this afternoon, but since I can't even look at that part of the timeline without a crash, I can't even replace the clips at that area. Am I overlooking something silly here? Any help would be appreciated. If I haven't supplied needed information, I'm sorry; and I'll be happy to add it.
