AE CS5 (10.0.1.19) Ram Preview - Audio stops and continue playing randomly

I already reported this issue to Adobe as a BUG but I want to ask here if somebody else have this problem or can confirm it.
Audio breaks/stops and continue playing randomly when 'Ram Previewing'
It happens mostly when the RAM is fully filled up with image cache files! When the Ram is not filled up totally with image cache files it happens rarely!
Steps to reproduce BUG / issue:
1. create a new composition with a length of for example 5 minutes.
2. create a new solid with size of 50x50 pixel and animate the position of the solid for a very long time so when ram previewing the whole ram/memory gets filled up with different image cache data (this is very important!). Alternatively you could use a long video file to fill up the RAM completely.
3. import a wave file .wav 16bit 48khz uncompressed which is very long for example 5 minutes.
4. insert the wave file in the earlier created composition which contain the animated solid or video file.
5. Set the work area bar (preview range) for the whole composition.
'Ram Preview' the composition until the whole RAM/memory is filled up with image data.
AE has to stop rendering because there is no more space available in RAM.
make sure 'from current time' checkbox is off.
6. listen to the audio which stops playing randomly for about 1-2 seconds and comes back and continues playing (***BUG***)
7. Now set the right handle of the composition work area bar (preview range) to less then the maximum RAM size
(less then the green cache indicator on the right side)
8. "Purge image caches" or "Purge All"
9. Ram preview the now smaller work area
10. listen to the audio. The audio breaks are gone! (***Workaround***)
Additional information:
I have the latest After Effects CS5 update installed (10.0.1.19)
This behavior is tested with different audio drivers inside After Effects CS5 (After Effects WDM Sound, Generic Low Latency ASIO Driver,  ASIO DirectX Full Duplex Driver)
I also tried different Sample Sizes Buffers (alternatively to the default 2048 samples) but without success.
Reducing the amount of RAM which After Effects can access didn't solve the problem!
System:
Win7 64bit all latest Updates, 8GB RAM, CPU: intel Core 2 Extreme QX9300, nVidia Quadro FX 2700M, IDT High Definition Audio Driver v6.10.0.6227
There is no driver problem on my system because After Effects CS3 & CS4, Premiere & Soundbooth CS3 CS4 CS5 have no audio problems!
I have lots of other professional audio software like Steinberg Cubase 5.... on the same system and they all work fine.
I also turned off AVG Anitivirus and Windows firewall for testing without success.
AdobeQT32Server.exe, dynamiclinkmanager.exe, PProHeadless.exe, afterfx.exe do not get blocked by firewall they have full permission.
The CS5 Production Premium installation went fine and without errors and antivirus protection was turned off for the installation.
Any help would be nice!

Yep, I agree with craulmedia....
It's 1 month ago after my initial post and no valuable feedback from Adobe although I filled out the bug report in addition to this post and provide my email for further information.
The only reason for upgrading from CS4 -> CS5 production suite was the use of all my 8GB RAM in AE and now AE can use it but when it's using it the audio have issues.
CS5 is on the market for nearly a year and still have such essential issues... And my fear rises there will be no valuable update fixing these issues but instead Adobe forces me to upgrade later this year to CS6 in hope something change...
I have had support request for different Adobe products in the past including telephone support, web support via Adobe ID... none with success the web support answered my request 3 weeks later with the message they will look into it... time went by and in the end the result was "Yes we know it's a known bug" the bug did not get fixed for that CS version. it even exists in the next major CS release! (talking about EncoreDVD here). Once the web support answered weeks later when I was in holidays and after some days I was not able to respond they closed my case. I reopened the case but never got an answer! Telephone support is nearly waste of time because in 95% of all cases it does not help to reinstall the whole operating system and talking to people who know less about computers in general or Adobe products then my mom - it's a waste of time.
I don't want to blame here anybody for things happend in the past I just want to point out that this time I choose an other support channel (bug report and forum post) but it seems that this support channel is also a waste of time after 1 month with no valueable feedback!
I bumped up this post 2 times and thanks to craulmedia for the third time.
And now here is my fourth time *BUMP*
All I got so far is: "I saw your bug report it's in the queue"
Is it still in the queue? which queue nr. does it have? how long will it take to get any answer? is it reproducible? Is it confirmed as a known bug by Adobe? Is Adobe working on a fix? When will this fix be available? Is the fix provided in form of an update or in the next major release?
OK, I know this is a user to user forum and Adobe people only stop by in their free time and there is no guarantee for any real support.
But it started out so good in the first time...
Last 2 things I want to add here:
1. Why should I provide my email in the bug report? Sure so Adobe can get back to me for further information... but wouldn't it be nice if Adobe would be so kind to give some status report to that given email as a small present for the enthusiastic beta testers ?
2. please Adobe take a look at www.uservoice.com already Autodesk started to move there with 3ds Max.

  • RAM preview audio will not play through bluetooth headphones

    I am using bluetooth headphones (Jaybird Freedom Sprint) to try and edit audio/video in after effects. However, when I go to Preferences>Audio Output Mapping and choose "Freedom Sprint" and click OK, close the preference window, and it will automatically go back to the default "Built in Output" when I open it back up. It will only play the sound through the Mac Pro tower I am using. Is there a way to get the headphone option output to stay permanently?? Is there a reason why it is not staying selected?  Another thing I forgot to mention is that all other sounds work (like iTunes, volume up/down) through the headphones except for the audio RAM preview in After Effects. How can I disable the audio from playing through the tower? Very frustrating!
    BTW - the only time headphones actually work is when they are plugged into the tower. These ones obviously can't be plugged in.
    Thanks! (Screenshots provided for help)

    Thanks! I definitely did try that first... (trying to find a solution with the headphones). You can't find any info about them online/their website. Regardless though, After Effects will not allow me to play the audio output through any other device except for the Mac Pro tower - even playing it through the LCD Cinema Display won't work.
    Thanks for your reply

  • Multiprocessing works for RAM preview, extremely slow and aeselflink crashes when in Render Queue

    Hello all,
    System specs:
    Hackintosh
    OSX 10.9
    3.5Ghz (overclocked to 4.2Ghz) Core i7
    Geforce GTX 580 classified 3GB Cuda GPU
    AMD Radeon HD 6870 1GB Display GPU
    32 GB of RAM
    System SSD
    5 drive internal RAID
    After Effects CC 12.2.1.5
    Cuda drivers up to date
    I'm having a problem with the render queue and multiprocessing. I have a moderate sequence with several effects and 3D layers. When I'm working in the composition, everything goes great. I can RAM preview and all my CPU cores will kick up to 100% and render the composition in no time all; with full resolution with no skipped frames. It works fantastically.
    Then when I go to render the exact same composition with the same multiprocessing settings, AE will hang at the "initializing background processes" for at least 5-10 minutes, during which the CPU will ramp up to 100% but no frames will be rendered. AE still remains responsive, as I can hit the stop or pause buttons and the queue will be cancled. But then the aeselflink processes (up to 8 of them depending on my settings, I've tried several) will still continue at 100% cpu load even with AE not set to render anything. I will have to go into the activity monitor and force quit each process. If I leave it for 5-10 minutes, it will finally stop initalizing and start the render, but the CPU will still run at 100% but the frames will crawl slowly forward at about 1 frame per minute, with an estimated 28 hours to render frames that were rendering in under a minute during RAM preview.
    I have tried both reducing the number of cores AE will use, adjusting the allocated RAM, and disabling multiprocessing alltogether. When I disable multiprocessing, the render slows to a complete crawl, and it will render around 1 frame every 5-10 seconds. Again, this is on a composition that rendered in less than a minute on full resolution with RAM preview.
    The only way to get this composition to render is to export it to Media Encoder, which will render it (without multicore processing, unfortunately) in about 8 minutes, still not the blazing fast RAM preview but at least it finishes it in under 3.5 hours (the amount of time that the multiprocessing disabled render in AE will take).
    Here's the multiprocessing settings that have been very stable and carried me through other projects. Disk Cache is not enabled. The only other thing that is disabled is the "Disable Layer Cache" under the Secret menu as the plugins I'm using (Plexus 2 in this case) doesn't like to update when the camera moves so this option has been disabled to force it to reset each frame.
    Does anyone know what is going on?
    Also, please don't tell me that I should not use multiprocessing or instruct me on basic steps as to increase preformance on my machine. I have been tweaking my memory and multiprocessing settings for a long time now, and it is completely stable in everything but this setup. So please no answers saying "just don't use multiprocessing". It was made for a reason, it's effective, and it's needed. And please don't say that it's the hackintosh, either, as it's the most stable and powerful computer I've ever used. Sorry for the disclaimers, I just want to have constructive help.
    Thank you in advance for your ideas!

    Hi Rick, not sure if you saw the part where I said please don't reply with turning off Multiprocessing, and I did not say that it works and is effective in all areas. However, if you actally take the time to read my post, you will definately notice that RAM preview with multiprocessing takes under a minute to render a scene. Multiprocessing disabled and rendered in AE takes 3.5 hours. In Media Encoder it takes around 8 minutes. Clearly it IS working and IS effective for my case and my rig. Any vendettas against MP does not help my situation at all.

  • After Effects CS4 freezing with RAM preview audio?

    Firstly, I'm on a mac.  This problem just started a few hours ago after I made some system updates.  When I hit preview in a comp with audio it runs through the frames, then locks up when it would normally start playing.  I just get that dang spinning beach ball of doom.  If I turn off the audio on the layer, it previews fine.  I believe the only think I had updated when this problem began was upgrading to quicktime 7.6.2.  Would this effect the RAM preview?  Since the problem, I've updated AE to 9.0.2 and OS 10.5.7 with no change.
    Anyone come across something similar?
    Thanks

    Mmh, well, seems ominous, but quite obviously QT is somehow involved. do you use any dedicated video hardware such as AJA or BMD cards? If so, the QT update may have introduced an incompatibilty with their drivers... Even if not using any such equipemnt, definitely check your QT system control panel. Also use OnyX to flush your QT components cache. They may just need to re-initilaized to function properly. Short of that I'm not aware of such issues, but anything is possible. If the issue persists, using Pacifist and downgrading your QT may be the only option. What Mac are you on exactly?

  • Really my question is about after effects, which then renders to a quick time movie.  I have imported music into after effects many times, and all of a sudden after import and playing it under ram preview, it stops about 4/5 through the work.

    when I import a song into after effects it only plays 4/5 and then stops.  I'm viewing it in RAM preview.
    the composition time is fine.
    can you help me???

  • RAM Preview Audio Skipping Issue

    - After Effects Version: 13.2.0.49 (This is the most recent update as I installed it today)
    - OS: Windows 7 Home Premium
    - So, I rendered out a clip from Media Encoder in H.264 format, and imported it back into After Effects and attempted to use RAM playback.  The video plays fine without skipping, but the audio plays back partially, and begins to leave out certain parts.  In other words, the audio says, "I'm going to try to spend more quality time with Luke, last time didn't go too well", After Effects plays back "I'm going to try to spend more - last time."
    - I rendered out a series of clips.  However, only the first two that I rendered in Media Encoder playback the audio in After Effects correctly, the rest all have skipping audio in AE only.  I can play them back in Windows Media Player perfectly.
    - My PC setup is: Intel Quad Core i5, 8 GB RAM, Nvidia GeForce GTX 650 series video card, 1920x1080 monitor, and 1 hard disk.
    - My GPU driver is: GeForce Game Ready Driver (version: 344.65)
    - I render all of the video clips using H.264 format in a .mp4 container.
    - Quicktime version: 7.75.80.95
    - I am only using After Effects for all of the video and audio and Media Encoder to render.
    - No third party effects or codecs.
    - I don't think I am using OpenGL features. (I'm not sure)
    - This, as previously stated happens when I preview the already-rendered clip in the RAM preview, but it also happens when I put the rendered clips together in one video and render them out again.
    - I am not doing any multiprocessing frame rendering.
    - I am not using the ray-traced 3D renderer.
    - If it helps, here's my output settings on Media Encoder:
    Audio settings:
    Video settings:
    NOTE: I followed the FAQ guidelines as best as I could.

    First, try exporting using one of the presets.
    Second, H.264 has highly compressed audio and AE does not like that very much. If you are intending to do more editing on this video clip then you should be exporting a production format not a highly compressed MPEG format. Your audio problems are most likely caused by using some non standard settings somewhere along the way. That's why you should pick a preset and not mess with the audio encoding at all.

  • After Effects unrender RAM preview after stop playing it.

    Hi! We have 5 workstations running After Effects CS6 on different computers, from HP z820, HP z800, and also on OSX Mac Pro, all of them with or AJA cards or BlackMagic Studio cards. On all of these stations, which they have no less than 24 GB or RAM, and working with 30 Seconds ads, so we have more than enough RAM to keep previews on RAM, they play fine once rendered to RAM, but we observe that most of the times, after hitting stop, and even without doing anything else, the green line is gone in a heartbeat, in some areas of the spot, this gets even worse if we use multiprocessing rendering, in which case, it always vanishes after playing and hitting stop. Without using the multiprocessing, it happens less often, and if we turn off the video monitoring with the AJA or Decklink cards, it happens even less often....  this is happening in several computers we use, and I find hard to believe that we are the only people with this problem? since I have not seen any other reports of this...  anyone?
    Thanks

    Other than the AJA and Blackmagic cards, have you added anything to the systems' hardware?
    No, but not sure if the video card...  I can, like I said before, load to RAM and play fine source footage, it never loses the green line...
    What plugins have you added?
    Many, but it happens right now on what I'm working on, and I have no plugins in use, only 4 layers with alpha coming from MAX which I'm comping together.
    What codec packs have you added?
    How can this be relevant? It happens with any format, on once rendesred to RAM, it has no codec, its the internal AE format. It happens with any kind of source.
    At what point in the complexity of the comps does this start happening? Is it number of layers or number of precomps in use?
    Well, right now is happening with something extremelly simple, just 4 layers from a 3D render and nothing on it.... I render to ram, it plays, I stop... green line vanishes....
    Have you seen this happen before or just in this version of AE?
    I have seen this for years... just never really paid much attention to it becuase never considered AE very good at it, but CS6 on of the sales points is how much better caching is... and its not in our case..
    As a side note: this is a user-to-user forum. Granted, we are often blessed by the presence of Adobe employees, but it's not guaranteed. There are official tech support channels and an official bug report page that you can use to make sure this is seen by an actual Adobe person.
    Thanks! I will report on the official channel once I have something I can reproduce on demand on how to make the program to fail.

  • Premiere Pro CC 2014 RAM issues, audio dropouts and export failures

    So I've upgraded to PP CC 2014, it worked fine for a while. Then I've noticed that while editing audio starts to dropout (I'm getting PP system message in the low right corner). I tried to dig up some info on the subject, but the only explanation I see that after couple of hours of editing PP eats up nearly all of my RAM.
    Any solutions?
    My specs:
    i7-2600K 3.4 GHz
    Quadro 2000
    32 GB RAM

    Take a look at your GPU usage with something like GPU-Z to see if both Premiere versions are using the same amount of MPE GPU hardware acceleration.  Actually with CC 2014 it might work faster because Adobe added in more 4k effects/features for GPU acceleration.
    You might want to download our Premiere Pro BenchMark (PPBM) and run it on both versions.  The H.264 very complex timeline has 4K material in it and usually shows Premiere Pro 8.xxx take about only half the time that Premiere Pro CS6 take to export that same timeline.

  • After Effects CS5.5 - Very Serious Performance Issues w/RAM Preview

    My system: Windows 7 Professional, two Intel Xeon X5650's, 12GB RAM, and a NVIDIA Quadro FX 4800.
    Problem: RAM Preview in CS5.5 gives me less than 2 fps (yes---two frames per second). This is even with the most simple of compositions. I created a 1080p 23.976 project with two simple solid layers and keyframed position and scale values for one of them with no other effects on either solid. RAM Preview gives me 1.8 fps.
    I still have AE CS5 installed and it gives me solid, predictable results with RAM Preview. When I create a similar test project inside CS5, it creates the RAM preview almost instantly and displays in proper realtime (23.976 fps).
    My settings for both CS5 and CS5.5 are similar  (and I have tried many variations in my attempt to fix this problem).
    PREVIEWS
    Fast Previews: Adaptive Resolution Limit 1/4
    Enabled OpenGL and both sub-options for OpenGL enabled.
    MEMORY & MULTIPROCESSING
    RAM reserved for other apps: 4GB
    I have tried various settings for Multiprocessing, all of which results in the same less-than-2 fps RAM Previews. Currently I have MP'ing enabled with 1.5GB allocation per background CPU and the actual CPU's used is 4. Again, no matter what I set it to, I get the same performance issue.
    On my screen magnification ratio setting, I am using 25% and my Resolution/Down Sample is set to quarter. On my preview tab, I have tried setting my resolution from the default of "Auto" to "Quarter" with no difference.
    In summary: On the same machine, AE CS5.5 RAM Preview offers terrible performance; CS5 RAM Preview offers great performance.

    Under AJA Preview there are check boxes, one for "Video" and the other for "Preview." I've checked and unchecked them both and I'm still getting poor RAM previews. No matter what I have toggled, I seem to get between 1 and 2 fps for my RAM Previews.
    I am not currently using the AJA card for anything. I will consider uninstalling it if this might possibly solve my problem. It's just a hassle to install and uninstall cards on a per need basis.
    If there are any other thoughts, I'd love to hear them. At this point, I'd do just about anything to have realtime previews back.
    The machine I'm using, by the way, is an HP z800 with Windows 7 Professional, two Intel Xeon X5650's, 12GB RAM, and a NVIDIA Quadro FX 4800. It has the following installed: CS5.5 Production Premium, AVID Media Composer 5.5.2, and AVID DS 10.5.1 (among other programs).

  • Unable to create image buffer after RAM preview

    Running into an odd and frustrating error. Built a comp using the new Ray-traced 3D renderer and now I'm regretting being an early adopter big time with all the problems I've been encountering with it. The latest comes whenever I do a longer RAM preview in an attempt to watch the whole duration of my comp. It will get to about 170 frames or so, at which point I've interrupted by pressing spacebar because I don't need to see all the way to the end of my work area (around 220 frames). It'll play the RAM preview back fine, and even loop it, but as soon as I stop playback, I get this error message: "After Effects warning: Unable to create image buffer." There's only one button: "okay" and as soon as I click it the same error pops up again and it will never go away, forcing me to close AE from the task manager. I've taken to saving before every RAM preview like I used to do with Flash before previewing my buggy swfs for fear I'll lose all my work after previewing. Any ideas about what might be causing this?
    Some more details about my comp:
    1920x1080 @ 29.97

    Yeah, some buffer is very likely not flushing when you interrupt the preview and then there is no more memory on the graphics hardware. Consider setting the work area and your preview options to use only the work area. if it finishes the preview "correctly", it may not suffer the issue. Beyond that - raytracing doesn't/ shouldn't care about the number of items. The math is such, that it makes no difference whether you render a million polygons or just one. Of course there are still limitations due to the GPU dependency, but I doubt you ever truly exhaust the cards' geometry buffers. Compared to pixel data that is a small amount...

  • RAM previewing and rendering not working correctly

    Hi,
    Today I was just about finished editing a video on CS6 and then when I'm about to add the last effect and render it it stuffs up on me:(. What happens is that while RAM previewing at some point during the loading of the preview it will stop loading, It will then proceed to play the ram preview on loop and when I press a button to stop it a small box pops up in the centre of my screen and the ram preview bar to show what has loaded (the one which shows green for parts that are loaded and blue for cached) turns black and sometimes other parts of after effects turn black. This has happened before and I fixed it by uninstalling and reinstalling After Effects about 6 times. I would do that this time though I would like to know the cause of it and any possible fixes as it is quite irritating. Another thing that may be happening is the RAM usage is slowly filling as I render. This has happened before on my laptop and I did not manage to fix it though it was not related to the first issue that time. The last time when it happened on my laptop the RAM usage eventually filled up to 100% and it would no longer render. I am not sure if it is happening this time as it is still currently rendering though I will update the thread if it does. Finally my render is going very slowly, I am not sure if this issue is realted to any of the above or if it is just the effects I am using though. My memory and multiprocessing settings are using 6 cores of 7 with 2 GB of ram allocated to each with multiprocessing on. My ram allocated for other programs is 6GB. To fix these Issues so far I have tried clearing the cache, purging the memory and image cache, restarting  my computer and reinstalling after effects. My specs are:
    i7 4770k non overclocked
    GTX 780
    G.Skill Ripjaws Z 2133mhz 32GB
    Samsung 840 pro
    Seagate Barracuda
    MSI Z87-G45
    H100i cooler
    Any reply is appreciated
    Thanks in advance
    Sam

    How much experience do you have with AE? Ram preview can be lengthened by adjusting the resolution of the composition window, different parts of the project can be previewed using the work area, and preview length and render time are both a function of composition frame size. Complex, memory intensive effects like particle systems will reduce the render time and the length of a ram preview. Without knowing the details of your composition it's hard to say if you are running into a bug, running out of resources, or experiencing normal behavior.

  • Ram Preview - Stopping after 40 frames

    Hi All,
    I've recently moved to After effects CC on my home computer, and for some reason whenever I try and RAM preview it stops after 40 frames or so...
    The animation is REALLY basic (full screen shape layers turning on and off to the music) and an mp3 file playing in the background.
    My computer spec is:
    21.5-inch iMac Mid 2011
    OSX 10.8.5
    2.8 Ghz Intel Core i7
    16 GB 1333 MHz DDR3

    I have the following multiprocessing prefs:
    I would greatly appreciate any help on the matter... the project seems far too basic for it to be having genuine issues with playback...

    Hi Rick,
    Thanks for the reply.
    I've changed the .mp3 file to a .wav file and that seemed to fix everything, for the time being...
    It previewed for 10 seconds fine, but after about 15mins of working on this the RAM preview area has started to shrink again and it's only previewing just over half (5 seconds).
    I changed my memory and allocated 4GB to other apps, also turning off rendering multiple frames... (by the way for some reason I can't get my 'actual cpu's that will be used' to change from 0? This seemed odd). Still no change.
    I've attached a screenshot of my comp details below, along with a shot of my screen when RAM previewing... (you can see the green bar does not go all the way). I'm not working with ANY footage which is why this is most peculiar, just the wav file so I can edit to the beat.
    Once again if there is anything else you can think of...

  • Shrinking ram previews, even with All Purged!

    Hi there,
    I had the same problem with AE ram previews on my G4 Powerbook that I am now having on the MacBook Pro which replaced it.
    What happens is the ram previews get shorter and shorter. I have two gigs of memory, not a ton, but enough for at least a minute and a half of ram preview time at half resolution (D1 project). I just opened a project, loaded up a ram preview and it loads well over a minute and a half. Then what happens is I keep working and creating new portions to ram preview and little by little the ram preview time gets smaller and smaller. Before long, I have a 20 second region selected for ram preview and it only loads 2 seconds.
    If I Purge All I will then get about 30 seconds of preview time, but soon after, it gets down to a second, and sometimes just a few frames. I have to quit the program and start it up again to get the full preview time... :(!
    Because this exact same problem happened with my last Apple laptop, I assume this is a problem not with the computer, or the particular memory, but with either AfterEffects, or some of the other software I have on my computer, which is Logic Studio, Flash, Illustrator, Photoshop CS3 and a bunch of smaller apps. But I really can't believe it's any of the other apps... Anyway, that's why I have written. To see if anyone else has encountered this problem, or heard about it.
    Thanks so much!

    Thanks again! I really really appreciate your advice.
    The format I have been using was quicktime DVC50 NTSC exported directly from FCP. And, again, this behavior is identical to the way AE behaved on other projects and an earlier version of the OS like 5 months ago... It's really since I upgraded to the latest version of AE. But I have been considering upgrading to 10.5 for a while now. Maybe now it the time... It's worth a try.
    I have purged the media cache. Again, it will free up some portion, but not all, and afterwards this "sticky filling" starts to happen much faster.
    Of course, after posting the blog AE behaved perfectly! Just to make things more strange! Hopefully somebody will have heard of this problem and know how to solve, or at least can offer more clues.
    Thanks again for your great help, Mylenium.

  • RAM Preview Problems in After Effects CC

    AE CS 6 RAM Previews work, but two problems to report with AE CC on the same computer. Possibly two faces of the same problem.
    1. Having QuickTime Player open while doing a RAM preview makes the RAM preview stutter. I quit the player, and now the RAM preview plays back without dropping a frame, though Info palate shows "fps: 24 (realtime)", but the RAM preview playback is slow: ie, a tenor sounds like a baritone.
    2. A RAM preview that looked and sounded fine last night, is now playing back slowly (tenor sounds like a baritone), though Info Palate shows "fps: 24 (realtime)". I have no other applications open. The only thing that changed is that I quit AE, slept the computer, slept a little myself, and then launched AE. Trashing the cache files (manually), rebooting, relaunching and re-RAM-previewing creates a functional RAM preview, so I assume there is some problem with the cached files or the retrieval of them.
    Is anyone else getting either of these? If so, what is your system configuration?
    Also, I posted on another thread that Quicktime import/render works with AE CS6 on this computer, but AE CC can not import, play, or render QT reliably (without throwing error messages). Perhaps all of this is part of the same problem.
    Thoughts?
    Cheers,

    CS 6 CC | Mac OS 10.8.4 | MacPro5,1 | 96 GB Ram | PROJECT & MEDIA drive: Mercury Accelsior > 500 MB/s read/write | CACHE drive: Mercury Accelsior > 500 MB/s read/write | Nvidia Quadro 4000 Mac | CUDA Driver: latest update | Wacom Intuos 5

    96 GB RAM is  accessible in 10.8.4 on my machine according to OWC. I'm working on a stereoscopic 4K project with large files and hundreds of layers. I regurlarly render with AE MP while working with huge files in PS, and am glad to see the % of RAM AE uses displayed in my render cue between 3 and 60%.
    I have 12 processors (24 with hyperthreading)
    I have reserved 10 for other applications leaving 14 for After Effects
    4 GB per x 14 = 56 GB for AE. leaving 40 GB for everything else
    I've played with what and how much I have allocated being sure to keep the CPU counts even, but this does not fix the RAM preview problems described above. Any other suggestions?
    Thanks,
    Benjamin
