I would first address the crashing.
You mention error messages, what are they, please?
Also, I'd look over this ARTICLE, as more info would certainly be useful. The more info, the better.
Right now this is my computer - http://www.uktsupport.co.uk/advent/laptop/8315.htm. It's just a basic laptop so maybe it's just not good enough. It's not a massive problem if that is the case, it's just the only one I have at this moment.
Sometimes Premiere just closes outright without saying anything at all but I have also had these errors:
- a serious error has occured requires Adobe Premiere Pro to shut down
- Adobe Premiere Pro has stopped responding (Windows error)
There is also this thing it does where pressing play on the preview will not respond.
The project is only a couple of minutes long and the files are 1280x720 MP4's mixed in with some MP3 files.
That laptop is way below minimum requirements and NOT suitable for editing SD material, let alone HD material.
If you were lucky enough to be able to run the PPBM5 Benchmark my guess is that it will be the slowest machine on the list, being at least 125 times slower than a fast machine. To answer your next question, no do not even consider upgrading. That is money down the drain. The only options you have are:
1. Get a new system, or
2. Do not use PR.
Also have a look here: Adobe Forums: System requirements for CS5
Sorry to be so blunt.
Harm the OP has CS3!
I don't know if you are talking about my version or not there to be honest but if you are then thats no problem, blunt is good I will have another PC to use again at some point anyway but I was just wondering. Thanks for your help.
FYI though, it can handle SD perfectly fine, it's just HD is has the issues with.
I completely overlooked CS3. I automatically assumed CS5+. My apologies.
Please disregard my previous remark, since it does not apply to your situation. I can't remember the exact minimum requirements of CS3, but one thing I do remember is that at least two physical disks were the minimum.
The problem you have with CS3 is indeed a starving for memory and disk I/O, but from my previous remark I still maintain that it is money down the drain to invest anything in this system. There will come a time when you want to upgrade to CS5+ and then, anything invested now can be thrown away.
Ok then, thank you
