Hello everybody.I use Quict time Pro 4.1.2 and I have an annoying problem when I play movies in the full screen mode.I have a 146MB movie that plays at full screen with no problems.I have also a 45 and 30MB file that when I put them at full screen the frames jump like crazy!!! I upped the memory of quicktime to 100MB but still have problems.
The 146 MB is at 720x576 resolution the other files at 480x360!!!!
What the f$#@ is going on???
HELP GUYS!!!!THANKS

what are the machine specs? OS?

why dont u upgrade to QT5?

is it just those 2 movies having problems?

I'm guessing that the larger file is a .mov file in a native QT format, while the smaller files are MPEG videos. MPEG just takes a bunch of decoding power, and you must not have enough left over to quite make it to full screen. The other possibility is an older video card that can't keep up.

A faster CPU (or newer vid card if that is the problem) would fix it. In the meantime, turn Virtual Memory off & reboot for the change to take effect. Try playing the problem movies right after booting, without any other applications running & demanding system resources. Trimming down your active Extensions and Control Panels might free up some more CPU as well.

I have an iMacDV400 with 384MB of ram.
The thing is that even in MPEG remember that iMacDV can play full screen movies...

Or perhaps you have a fragmented HD, and the large movie file is all in one piece, but the smaller ones are in multiple parts, and the HD is searching for all parts, and that might lower your frame rate.

Nope.Out of luck on this one too!!fragmented file was one of the first things I checked before posting.So ARGHHHH!!!!!! I think I'll just stick with my problem and be happy about it!!!! Anyway thanks to all of you guys.But still if anyone has any more suggestions post them.And who know I might some day solve this f@#$% problem.

well, you could nail down whether the file type is the problem by converting all the files to quicktime movies...

What are the CODECs used in the larger and smaller movies?

Sørensen makes smaller movies, but the CODEC requires more CPU horsepower to decode and play in realtime. Slower machines will drop frames to keep up.

Also, are you "presenting" the movies, or just playing them blown up to full screen? "Presentgin" (req QTPro) the movie will drop the screen res to 640x480 before playing the movie, thus reducing the CPU load. Note: QT4 does not take aspect ratio into consideration when presenting "full screen." QT5 fixes this.

Another thought I had was to boost the std RAM allotment for the QuickTime Player.
