Clarification: The source file is a M4V. The playback he is attempting is in the edit timeline. Thanks!
What is the CPU on that Mac?
Does the friend only have a single HDD? What is the RPM speed of that HDD?
intel quad core i5 2 something ghz, and the drive is one internal running @ about 5200 rpms I believe.
I see at least 3 problems
1 - this is the CS5 forum, not the CS4 forum
2 - what is NOT in the trial http://kb2.adobe.com/cps/407/kb407938.html so that file may not be supported
3 - grossly underpowered and below specifications... need an OS drive and a data drive, as a minimum
Trying to use only ONE Hard Drive for Video Editing
You are a music conductor, with a baton that you use to point to various parts of the orchestra... this is like Windows pointing to various parts of the hard drive to do Windows housekeeping or to load program segments for various functions
Now, at the same time and with the same hand... while still using the baton to conduct the orchestra... pick up a bow and play a fiddle... this would be doing something with your video file at the same time as all the other work
You as a person cannot do both at the same time with the same hand
A computer is a LITTLE better, in that it can switch from one kind of task to another very quickly... but not quickly enough for easy video editing
One hard drive is not as good as two which is not as good as three
1. I should have said CS5, that's what he's using.
2. Thanks, this is probably exactly problem.
As John points out, the computer is underpowered, and then severely hampered by both the single HDD, and the RPM speed. For smoothest Audio & Video playback, 7200 RPM is highly recommended.
Look guys, no offense, but people have been editing dv video at way higher
bit rates on computers since the 90s. You can't chalk this up to the
It's probably the unsupported videos, that's what I recommended, but
seriously, I know processing video is intensive work but don't tell me that
premiere can't run an edit because the mac isn't nice enough.
You can't chalk this up to the computer.
This is incorrect. There are easy codecs, like DV that are lightly compressed using simple algorithms with low resolution and there are very difficult codecs, that are highly compressed using very complex algorithms and high resolution, like AVCHD.
Look here: Adobe Forums: System requirements for CS5
The fact is that this computer does not meet minimum requirements even for DV material and is way underspecced for difficult codecs.
If the playback stops completely, instead of just dropping lots of frames, then have him repair his permissions. If necessary, have him set up a root account and log on to it, launch Pr, log off and then back on to his normal administrator account. That should fix the stoppage issue. Warn him, though, that he may still end up dropping lots of frames during playback due to his CPU and disk setup.
