Eventual audio RAM preview problem...

AE CS3 (with Production Premium): When I include audio in my RAM previews, at first, the previews are instantaneous (as they are supposed to be), but after 15 minutes or so, AE starts to take a long time to RAM preview any comp that has audio in it. When I disable audio for RAM preview, everything goes fast again. If I shut down AE, and start again, everything is good again - but the same problem starts all over again and eventually, I have the same problem with audio. This problem happens even if I occasionally purge the memory cache. Any ideas?
I have 4 GB of RAM.
I have enabled the 3GB switch.
Win XP Pro.
Dell Precision T7400 - Dual Quad core.
Lots of HD space.
Nvidia Quadro FX 570.
Sound Card: Creative Soundblaster X-Fi

  • 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,
    Benjamin
    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,

  • I got render and RAM preview problems. help?

    i got render and RAM preview problems with after effects! please help me
    when i started on a project earlier today the RAM preview was failing and it stoped making a preview after about a second, when i hit the RAM preview buttom again it continued to load and stoped again after a half second, and it continued to do that till it wasn't loading at all, just playing the same thing up even doe it haden't loaded the whole composition! BUT if i moved the (thing you see where you are on the timeline in need of a better name) it started loading a little more and then it stoped again.. so after alot of problems and moving i managed to make a RAM preview of the whole composition..
    now the real problem: when i was done with my project and i was going to reender i did like this: i added my composition to the render queue, chosed my render settings and started to render, after exactly 37 frames it stoped and no window or anything poped up, the only thing that was telling me something was wrong was the render status, and it said: ''failed at 0;00;00;37'' that's not even a second! and BTW when i render after effects only uses 12% of my 6GB RAM memory.. i dont know what to do! i've tried other render settings but the same thing happens! can anyone help me?
    BTW i'm swedish and only 14 so i might misspelled something..

    Start here and make sure that you understand how RAM preview is supposed to work first:
    http://forums.adobe.com/thread/424030
    What version of After Effects? Have you installed the recent updates? What operating system? What kind(s) of source footage? Has this ever worked before? What other software are you running? Do you have any third-party effects or codecs installed? Are you rendering with OpenGL?
    What are your Memory & Multiprocessing settings? Are you using Render Multiple Frames Simultaneously multiprocessing?

  • After effects cc RAM preview problem

    I recently bought a new rig 
    i7 4790K running at stock
    8gb 1866mhz corsair vengeance pro ram 2x4gb
    EVGA GTX 770 2gb superclocked
    WD Black 1TB 7200rpm
    Samsung 840 Pro 128gb
    Asus Z97-PRO motherboard
    I run AE and open a file and import my clip (59.94fps) and add twixtor and then hit ram preview to see if all is good and it either takes a little bit longer than it should
    or it would say "Rendering frame switching to foreground" When this happens all seems ok but after the preview I can not scroll through the timeline without lag and pixelation again like as if I havnt hit the ram preview. So it would have the green bar above the clips showing for the ram preview but once the preview is over I can scroll through the timeline for a second then the green bar goes away. I know that the pixelation is due to adaptive resolution
    but I have tried changing that to "fast draft" and the pixelation stops but still struggle to view in timeline. I have the preview resolution set to third or quarter.
    I thought that getting higher clocked ram would solve the problem atleast a little more. But not to much. So my main question is what am I doing wrong? Or how can I correctly setup AE or my computer to handle this?
    The main clip is actually 200fps but I go to File>Interperate footage>Main>Conform to framerate
    Changing it from 200fps to 59.94.
    My main frustration is I see videos of the kinds of clips I'm editing posted by kids that edited them and I think theres no way they have a pc as expensive as mine that would allow them to edit these clips. So Its gotta be something I'm doing wrong.
    Thank you to anyone that helps so much!

    Well, for starters, turn off MP rendering. That warning during RAM previews is a clear indication that you are using it and well, with just 8GB RAM it doesn't exactly make sense. The rest is too vague since you haven't provided any proper details about your source file, but suffice it to say that temporal mangling of any kind can have weird effects, even more so if your source files are compressed. Therefore the pertinent thing to do first would be to convert your file to an uncompressed intermediate format, including conforming it to your target framerate. In addition you may simply consider not using any fast previews or the disk cache at all. It is known to be flaky with temporal plug-ins. set your comp to Final quality to enforce software mode rendering.

    They have said that it is set to be fixed in the next update. Which should be within the month, if I'm not misremembering.
    EDIT: I was misremembering. It is an issue that they're aware of, but are still working with Apple to try to find the source of the problem and, thus, the fix.

  • Super slow audio RAM preview issues in AE CS5

    Hi all,
    I've been having a tough time previewing audio while working in AfterEffects. I'm using Version 10.0.2.4, running on a 2x2.66 GHz 6-Core Intel Xeon Mac Pro with 64 gigs of memory.
    I've opened up projects that have never given me any issues in the past and I seem to be experiencing the same issue, over and over again:
    When I try to preview a comp with audio (either hitting "0" on the keypad, or "." on the keypad), I get the "spinning beach ball" for at least 20-30 seconds before the audio kicks in. When I disable audio in my preview window, I have no delay with the RAM preview.
    This happens with .aiffs and .wav files.
    I've done the usual tricks -- restarting my machine, double checking to make sure there's not an issue with my speaker setup, repairing permissions, checking for updates.
    Has anyone else experienced these issues, and is there a workaround? I have a job coming up that requires me to quickly preview audio and waiting 30 seconds every time I need to check my progress with a RAM preview is going to be soul-crushing.
    I'll happily answer any questions -- I'm sure there's a bunch of info I've left out, and fingers crossed it's just some setting that I've ignored that's causing this issue.
    Thanks,
    Dan

    Sorry for all the questions, but...
    What path/hardware does your audio take to be output?  Analog from the Mac?  Via a third party card like an AJA or Blackmagic device?  USB speakers?
    Have you specified the audio device in the AE audio hardware preferences?  Have you tried outputting to a different device, or removing the device and just using the standard system audio?

  • After Effects Rendering Problem and RAM Preview Problem

    I posted a question about this yesterday but I thought I would repost it with more detail!
    I have a restless issue here with rendering and RAM preview. I am simply trying to create a viral ad which uses the cloning effect I achieved with masking for my college coursework and I have completed the process of creation but I have ran into problems. The RAM preview will only play up to a certain point then it will just stop and this effects the final render because it gets to the point in the rendering where the RAM preview stops and then a message will pop up saying the rendering has failed or something? (Screenshots Below)
    I have tried RAM previewing just one of the three videos I am using and it still stops at the same point.
    I am using .avi files and have tried converting to .mov, .mp4, .wmv all of which didn't work.
    I am using After Effects CS4 ver 9.0.0.346
    My computer specs

    It's quite urgent and I hope someone can help!
    Cheers!

    With just 2GB of RAM, I'm impressed that you can generate that much of a RAM preview.  RAM previews use RAM. When they run out, they stop.
    Have you tried rendering the clip using the Render Queue.  If so, does it also report an error at a similar point?  If it renders correctly from the queue, you're done.  If it doesn't, you probably have a corrupt source file.

  • RAM preview problem!!

    Hi guys & girls!
    My after effects will only render 12 sec +/-. Then it automaticlly starts the clip and when I press it again, Nothing happens.
    I tried downloading 5,5 & 6 & CC.
    I dont know if it is any problems with my RAM, maybe too much used?
    I would be very happy if you fixed this for me or help me.

    4GB RAM isn't much. The numbers make perfect sense and are completely normal. There's a reason why it's called  "RAM preview" if you want longer previews, get more of it or reduce the preview resolution.

  • 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

  • Problem with RAM preview in Windows 7, AE 5.5

    Hi there, I'm kind of a newbe with After Effect 5.5, have to make an animation for school and although I've already figured out how to make some magic with the program, I'm stuck on the RAM preview (yes, the one you get by hitting 0 if anyone asks). It gets stuck after 15-22 fps and that's it. I've searched forums, and comments and articles and whatsoever and the authores where having this issue when having Macs. Well, I don't, that's what I have:
    64 bit Windows 7
    Intel Core i7-2630QM CPU @ 2,00GHz
    6,00 RAM
    graphic card NVIDIA GeForce GT 540M
    (any more details needed?)
    I've also tried many combinations with checking/unchecking OpenGL, changing Video Preview (Computer Monitor Only or IEEE 1394 Pal <=don't even know what that is, but maybe you'll want to know), and of course Multiprocessing (image below) turning it off ond on.
    Compositions in my animation are for now just jpg's, png's and some psd layers, with some scaling and small dropshadows, nothing too fancy for now so I'm even more surprised I get the "Insufficient RAM" allert. (AE is the only running program except for GoogleChrome to search for possible solutions) Of course I need to add the sound but it's pointless until I figure out the RAM preview problem.
    I think that's all the details, but if you need more just ask.
    Please help me guys (and try to answer in simple English), it's really getting on my nerves and my deadline is coming...

    I'm not sure that I completely understand what you are saying. Depending on the amount of available ram and the size and frame rate of the composition (not in your post) you may only get 15 to 22 seconds of playback. If it's only playing back at 15 to 22 FPS then you're choking your system. The first thing to do is to try setting the resolution of our comp to half and the zoom factor to 50%.
    Now that I take a close look at your screen shot, that's not going to help much. Surprise, surprise! You don't have nearly enough ram to have Render Multiple Frames Simultaneously checked.You need 4GB per processor minimum. With 8 CPU's you'll need 32 GB of ram to take advantage of all your cores for AE and you'll still need 1 of them for background apps. Take a close look at the settings:
    How much ram is allocated for background apps? 1GB, How many CPU's will be used for the background apps like writing to disk and reading from disk, which are necessary for ram preview? 0, zero, nada. That's not exactly accurate or your system wouldn't run at all, but it shows the problem clearly. You've manually choked your fairly powerful computer by tying upp it's resources in a manner that causes it to choke on memory and read write cycles. Even with 6GB of ram you've starved the system to death.
    You've also allocated all of your ram to AE. Don't do that. Leave at least 1 GB for other apps, 2 would be better.
    Redo the settings and AE should work just fine. BTW, this info is clearly stated in the ram and memory allocation help pages for AE.

  • CS6 - After generating 3-7 RAM previews w/multiprocessing, MP stops working

    When I start AE (CS6) 10.0.2 (Win7, x64), previewing a 10-15 second scene with multiprocessing works fine and is very fast. After making 3-7 different RAM previews by pressing numpad 0, AE will no longer generate these previews, and instead will either say that it's preparing to do so, or stop at having rendered "2 frames out of x". I can see that it has stopped working because in the Task Manager, the different instances of AE will not be consuming more RAM to prepare for frame renders. AE and my system will still work fine, and I can still view the RAM previews that I made beforehand, but to get MP to work flawlessly again, I need to restart the program.
    I'm using an 8 core Xeon processor @ 2.6 ghz, with hyperthreading enabled, and with 32 GB of RAM for this processor. I've read that decreasing the amount of available cores can help with AE multiprocessing. I've tried that, as well as playing with the amount of RAM that each core gets, and it still will inevitably hang. I've also read that problems like this can be due to hard drive bottlenecks. When I look at Windows Resource Monitor, this isn't a problem at all. I'm using AE to make compositions with JPEG time lapse sequences that can be anywhere from 2,000x2,000 px to 25,000x20,000 px large, and often with multiple JPEG time lapses together. It's for this project in case you're curious.
    I spent a lot of money on this system, and plan to add another 8 core Xeon processor along with another 32 GB of RAM just to get faster renders (it's a dual socket ASUS board). Hopefully there's a fix for this flakey multiprocessing situation, or will be an update in the future. I think turning MP off does work, but it seems needless to do something 8 times as slow, or to have to always restart the program just to use a basic feature.:
    EDIT: I should also say that rendering final compositions with multiprocessing ususally works. For 2-5 minute projects, it almost always works. Rendering 30-70 minute compositions sometimes works. Sometimes it crashes during these longer ones, and I have to try repeatedly, and eventually it'll work. Sometimes doing things like emptying the Media Cache works.

    Good call. I have done that for previous projects - it works great.
    Great idea re. rendering individual frames! - I hadn't thought of that.
    I've tried doing a network render, but I have found that it is actually slower than using just my 8 core Xeon machine. It doesn't seem like AE is smart enough to get both computers to work out their long-term schedules for which frames to render far enough in advance. I think that the Xeon machine will load footage into the RAM to get ready to render a frame, which the second computer ends up rendering instead-thus negating that work. An alternative to this overlapping of effort could be giving the Xeon machine 3/4 of a project, and giving the second computer the last quarter, so that they wouldn't have any chance to render frames that end up being rendered by the other computer. But maybe I'm doing something wrong.
    But rendering the final sequences works great, and the fact that it crashes on the longer sequences seems more to be a symptom of my workflow rather than anything else. The main thing I want to fix is this pesky multiprocessing RAM preview problem that makes me have to restart the program often.

  • After Effects CC not saving ram preview when switching to different tab.

    Okay so just recently upgraded to CC and have been experiencing some ram preview problems.
    What happens is I will do a ram preview, watch it, then switch to a different window (Chrome, word, etc)
    and when I go back to AE and do a ram preview it does it all over again even though i haven't changed anything in the comp.
    I dont believe this was a problem in CS5.
    Any help on what settings i should check or if its a coding problem would be appreciated.
    Some specs:
    16gb ddr3 ram
    AMD FX-6300
    Radeon R7 250
    Everything Program/Cache is on SSD and the project file/video files are on Ext HDD

    Okay it's kind of fixed. (it isnt deleting it like it used too)
    i cleared my cache which was about 30gb, but I still had about 20gb of free space when i cleared it
    but Now I am getting some crashes and other stuff (colored bars, i already read thats getting fixed though)
    Do you think lowering the CPUs used to 3 will help?
    Ill update if it does it again when the cache is getting close to full

  • Audio Problems during Ram Preview

    Hello
    I'm having a unique issue with my audio playback. Video playback works fine, but when I ram preview or audio preview it makes my computer stall for 10 - 20 secconds, then plays. the audio ether sped up, or slowed down (different each time). Once this happens once, I can then ram preview this area again, and it works perfectly, untill I ether go to another track, composition, or program, at which point the problems starts all over again. Anyone have any ideas?
    I'm using a mac tower 8-core 2008, just recently put in an intel SSD drive for OSX Mavericks. in 14GB ram.
    The audio is a wave file.
    Thanks for the help!

    Heres the wave file that Im using
    However I feel like its not the Wave file at fault, because the issue also occurs on myfootage audio which are AACs, these are their specs
    its having trouble reading the audio files for some reason. Stange.
