Slow and lagging After Effects CS5.5

Hello!

 

I've tried to add some effects and preview the video with AE CS5.5 but editin is very painful. I try to preview and my fps is from 3-14 fps. It's painful to edit.

 

The editing video is 1280 x 720, 13min long and I've edited in Premiere Pro CS5.5 and exported it as a uncompressed AVI file. The size of the file is 16,7 Gt. I've added two effects: Remove Grain and Sharpen. I've tried to preview with Space and then FPS is about 14-16 fps but with Numpad 0 it quickly goes through the video and then it previews the video with 3-6 fps. It's just horrible to preview.

 

I've disabled "Enable OpenGL" and when I preview with space, there's no difference in fps and same thing with numpad0 preview. I've also tried to change the "Render multiple frames simultaneously" settings but with no success. I'm using current settings:

 

RAM reserved for other applications: 6 GB

 

Installed CPUs: 8

CPUs reserved for other applications: 4

RAM allocation per background CPU: 1.5 GB

Actual CPUs that will be used: 4

 

I've also looked at my HDD activity when I preview, the drive with caches and previews don't write at all, just read the video from the drive (cache, footage, previews, and captured are in the same drive)

 

Is there any ideas to improve the performance? Do I have to change my hardware? Do I have enough RAM or is my CPU too slow for this? And is the normal preview with space or is the numpad?

 

Current hardware:

 

Intel i7-870

16Gb RAM

Nvidia GeForce 8600GT 512Mt

Samsung F3 1TB 7200rpm - OS Drive, software, AE, Premiere Pro and etc.

2 x Samsung F3 1TB 7200rpm RAID0 - Uncompressed Footage, cache, scratch disk, video preview, audio preview, captured audio, captured video.

2 x Samsung F4 2TB 5400rpm - Footage Both have same files, files straight from camera, not edited, completely raw material.

Dell U2211H - monitor

LG L1715S - monitor

Logitech G35 - headset

External speakers

Windows 7 64bit Ultimate

 

All my drivers are up-to-date and my Windows 7 is reinstalled few weeks ago (clean install)

    Turn off MP rendering and also try to run with one screen only. Could be either a file I/O issue or something with your assymetric monitor setup...

    Sorry, no help. Same fps and laggy. I don't think that it's problems with my files because this common issue with any file. So anything I try to edit, this is a common problem. Not just this project, unfortunately.

    If you're actually trying to EDIT in AE, and not just using the term "edit" as a way to talk about doing effects an compositing work in AE, you should know that AE is just about the worst video editing application known to mankind.  Use an editing application like Premiere, Avid, Final Cut Pro, or even that God-awful FCPX.

    Sorry for wrong term. I mean I've edited the file with Premiere Pro but AE I'm just adding grain removal and color correction and all kinds of stuff.

    If it's not too much trouble, try unplugging/ disabling the RAIDs and definitely check their setup. If they are unstable or have flakey drivers, this may severely throw things off. Just a guess, but has happened in the past...

    No luck sorry, with Premiere Pro, RAID0 system works really well. So I think it's not with the RAID setup, but seriously, I'd wish it would.

    Any ideas? And what kind of file format do you recommend to use when I export my video from Premiere Pro and then edit it in AE?

    Okey, little progress have made with this progress. I've lowered the preview resolution to quarter and fps rose from 13 to 20-22. But still, it's not realtime. Should my pc have enough juice to run this? And is it normal that when I preview, AE uses 3-4Gb of RAM and my CPU usage is about 30-60% and two cores of eight are unused (I've told to AE to use 8 cores, 4 of them are HT cores)? And my RAID setup usage is about 3% (which is just the reading, if I move the video to the other drive, usage of RAID is 0%). Is this normal?

     

    I've also tried to move my video to the other drive, no success.

    You've never said, I don't think:  do you know how to do a RAM Preview, which is AE 101-type stuff?

    Well, I preview my footage with RAM preview (numpad 0), am I doing right? I haven't learned everything yet and I'm still learning. When I RAM preview my footage and preview the footage, it's realtime until I clip somewhere in the timeline. The green "preview ready" area is gone, so it's again, very slow.

    Hi there St. Apollo. I am going through the exact same ordeal as you did with AE CS5.5 and cs6. I have similar specs as you do but on a mac instead. Was just wondering were you able to find a good solution to this problem in the end and if you did, can you please share?
