I have AE CS5 on my Mac. My system is 27" iMac core i5 with 12 GB RAM DDR3 1333 MHz with quad core.
I rendered a 40 seconds clip with an earth spinning.
I output it to mov format in 1920 x 1080.
When I did a RAM preview, it was fine & the earth was spinning smoothly.
But the output file (in mov) - (I did thru Composition > Make movie) when I play using QuickTime player is jerky at 20th Sec to 29th sec.
I then import this mov file into Final Cut, it look stuck in the Viewer but was perfect on the Canvas.
When I render in Final Cut, the output file as mov and use the same Quick Time player to play it & it is perfect.
Can I know what is the reason that it is not working in Quick Time the first time when it was fresh out from AE ?
The default render settings use Quicktime Animation codec at best quality. These files will not playback smoothly because the data rate is too high for the hard drives to keep up with. The animation codec is a lossless codec designed not designed for playback.
Final Cut uses compressed codecs designed for playback as the default. I'd suggest that you open up the help files (F1) and read the entire section on Rendering and Exporting (link).
Thanks Rick & Szalam for the response !
Really appreciate it !
