It has been an up and down after effects cs4 mac road with me since I got CS4. Sometimes it seems to work perfect, exporting and rendering very high resolution after effects cs4 release date clips. Well today I created a leader for my corporate videos, its HD but by no means the highest resolution piece I have tried to export. Whenever I do export one of

2 things happens, occasionally it crashes with AE looking for more memory, but usually it just freezes on a particular frame. For example the export is something like 700 frames, so it will freeze on 85 and just stay there like its still exporting with no progress. Any ideas? I am running a dual core processor 2.5ghz along with 4gb of ram on after effects cs4 review a Windows XP system. I should have enough ram and memory to get this clip out....Return to posts indexReport Post •Re: After Effects CS4 crashes or freezes on exportby Dave LaRonde on Sep 29, 2009 at 6:34:19 pmThere are three common things that can affect performance in that manner: 1) you're using Open GL -- turn it off for rendering. 2) you're using multiprocessing incorrectly -- again, just turn it off 3) you're using HDV footage -- you'll need to convert it Why convert HDV footage? Read on.... Dave's Stock Answer #1: If the footage you imported into AE is any kind of the following -- footage in an HDV acquisition codec, MPEG1, MPEG2, mp4, m2t, H.261 or H.264 -- you need to convert it to a different codec. These kinds of footage use temporal, or interframe compression. They have keyframes at regular intervals, containing complete frame information. However, the frames in between do NOT have complete information. Interframe codecs toss out duplicated information. In order to maintain peak rendering efficiency, AE needs complete information for each and every frame. But because these kinds of footage contain only p

3D programs, After Effects doesn't use a scanline renderer. Instead it renders each layer and then stacks it on top of the previously rendered layers. While this gives great performance for layers that can be cached and use several times without re-rendering, it can spell disaster when http://generalspecialist.com/avoiding-the-after-effects-error-could-not-create-image-buffer/ you are trying to work with bigger sources and output resolutions. While you can use Shake to http://www.provideocoalition.com/tip_force_an_after_effects_render_not_to_fail/ zoom in on a giant 30.000 by 30.000 pixel image on an old machine, doing the same thing in After Effects takes a bit of imagination, plus a knowledge of how to tweak AE's memory settings. Basically, it comes down to the memory being to fragmented for AE to be able to hold the entire frame/layer in one contiguous piece of RAM. Here's how you avoid that from after effects happening: 1. Set Your Preferences CorrectlyStart out by making sure you have set After Effects to use the optimal settings. These should always be your default values, and you should reset them according to these settings once you have gotten around the image buffer errors!Maximum Memory Usage: 120%Maximum RAM Cache Size: 60%Enable Disk Cache: OnMaximum Disk Cache Size: At least 2 GB (I use 8-12 GB, typically)Prevent DLL Address Space Fragmentation: OnThe Maximum Memory Usage tells AE how much of the total amount of after effects cs4 installed RAM it can use as a maximum. Why 120% Maximum Memory Usage you might ask, why not 100% or even a sensible 95%? Well, since running slow sure beats running out of memory, that's why! If you set it over 100%, AE will use the harddisk as virtual memory (slow but sometimes necessary.) The Maximum RAM Cache Size is the amount of RAM (set in "Maximum Memory Usage") that After Effects uses to load sources, render effects and composites into, plus to store already rendered frames in. The setting of 60% is a moderate one that over time has proven to work optimally for most projects. Lowering this value will slow down your rendering and previewing speed, but it is sometimes necessary in order to render large layers/comps. The Disk Cache is where AE can off-load already rendered images/frames/layers/comps onto your harddrive instead of throwing them away when you are running short on RAM. Note that AE will only use the Disk Cache if it is faster to read a frame from the Disk Cache than it is to re-render it.If possible, put the Disk Cache on a fast harddrive, preferably not the same as your operating system or your source material (the above screen shot was taken on my laptop, where you seldom have the luxury of three drives.) If you're on Windows, make sure you check Prevent DLL Address Space Fragmentation, as AE will then try to keep more of the memory in larger chunks. It should be lef
to Fail Tip: Force an After Effects Render not to FailHad it with Out of Memory errors? Here's a hack to help in CS3 and CS4. by Mark Christiansen April 29, 2009 Uncategorised If you've ever tried rendering a composition made up of one or more large images - say, a single huge matte painting or several layers of 4k footage - you have probably encountered the dreaded Out of Memory error causing your render to fail. What to do about this? Unfortunately, most of the strategies you can take to play by After Effects' rules involve compromise - slicing up that big matte painting or shrinking those source files. Sometimes that's okay, but for the times when you really need that render, try the following. You may already know about the Secret or "Schecret" preferences in After Effects. Hold the shift key while you open any of the Preferences submenus (just pick one) and an extra menu item appears in the actual Preferences panel entitled "Secret." Here you can make various changes to slow After Effects down in order to keep rendering, disabling the Layer Cache and purging data between frames, even ignoring actual error messages during a render. This extra "Secret" category is full of options that are hidden because they have downside consequences if you don't absolutely need them. But what if the one frame you're on still won't render? At that point, you have to play dirty and use a tip I heard from Matt Silverman when he and I co-presented at SFMograph earlier this year. The steps are as follows: In Preferences, under Media & Disk Cache, check Enable Disk Cache and choose a location for your scratch disc. Be sure to raise the value to at least the amount of RAM you're trying to replace. An extra zero is added to the default Disk Cache setting to stand in for 20 GB of memory. With a RAID with over a TB, this is barely a blip. Still in Preferences, under Memory & Multiprocessing, raise the RAM to leave for other applications to its maxiumum. It's probably best to leave Multiprocessing off. Look carefully: the amount of RAM allocated to After Effects and to the system are inverted from their defaults. AE is so starved for
