Slow play back after rendering - help please
on Mar 1, 2010 at 9:08:58 pm

Hey, i have a problem where once i have rendered and i go to play back my movie to where i have saved it, it goes extreamly slow, freezes and jumps (while rendering its fine). However when i export the movie and do it that way, the play back is fine.

Any ideas would be great, thanks.

It looks like a codec or configuration problem. If you tell me about your computer configuration and players-codecpacks on your OS I may help you to fix this..

configuration is good! ( and perhaps you should turn 5 gigs to 4 or 6 gigs. Because Rams like to work as twins. 1 to 1 or 2 to 2) and the second means like BS-player, mediaplayer classic, K-Lite codecpack etc. whatever if you use one of them just remove all and restart your machine (even the softwares don't warn, just restart) and install them by this sort: 1st - K-lite codecpack by default settings(I think the last version 5.7.0) 2nd Bs-player (free or pro, it doesn't matter) Anyway if you don't use them just get them from the internet by google search, then install like I have told above.

Always cinema...

Everything's probably fine. If you rendered a high-quality file, your hard drive simply can't keep up with the file's high bitrate. Happens all the time. You did the right thing... so how do you make it play? Convert that nice file something the computer can play back. Read on:

Dave's Stock Answer #3:

Don't use AE to compress files for final delivery. The various compressors are there only to make quick 'n dirty files showing a project's progress to producers, clients, the kids, etc. AE is incapable of doing multipass encoding, a crucial feature that greatly improves the image quality of H.264 and MPEG-type files in particular.

Render a high-quality file from AE, and use a different application to do the compression. Popular ones are Adobe Media Encoder, Sorenson Squeeze and Apple's Compressor, which comes bundled with Final Cut Suite. Even compressing in Quicktime Pro is better than compressing in AE.

Making good-looking compressed files is almost as much an art as it is a science. It is NOT straightforward at all. I recommend asking a few questions at the COW's Compression Techniques forum.
