Ram Preview only part of Composition

Might be a stupid question but I couldn't find it anywhere in the help files, do I have to RAM Preview from the current time to the end of the composition? Is there a way I can preview say.....the next 5 seconds?
Just trying to sync audio and graphics and there has to be a better way to do it than RAM Preview over and over.
Thanks in advance,

Here's a pretty handy thing to know: when you scrub your audio to find just the right point on your timeline, make sure the Caps Lock key is ON. This prevents the video in the comp from updating, and it's a snap to find the right place in the audio.
Then put a marker on the timeline: Shift-0 thru Shift-9 on the ALPHANUMERIC part of the keyboard, not the numeric keypad. You can then jump to the marker, just by hitting the 0 thru 9 keys, using the ALPHANUMERIC part of the keyboard, not the numeric keypad.
No RAM Preview necessary!
Want to re-use those timeline markers? Just drag 'em off way to the right in their little "timeline marker house"... I forget its proper name. It's so difficult to remember such trivial little things without a proper graphic map of the AE interface. Adobe USED to print them, y'know...

Why is my RAM preview only playing the first 7 seconds of my video?

When I try to RAM preview my animation so that I can hear audio it only displays the first 7 seconds and then repeats. The entire clip is 35 seconds long.
Help please!

Random Flashing Color Bars within Quicktime Files during RAM Preview Only

I have been getting random color bar flashes within quicktime files in AE CC during RAM previews using Multi Processor rendering. Files other than .mov seem to not have this issue (although I have seen it twice...though it may be due to quicktimes in the comp). The rendered output using MP rendering is completely fine. If I turn off MP rendering the ram preview is fine. The source material is coming off a RAID 5 at 600-800MBs, I have moved the footage to a local SSD and a standard spindle drive with the same results. I have tried everything.....disabling GPUS in preview, disabling Fast Adaptive Preview, Disabling Disk Cache, Adjusting MP settings and RAM usage per core, disabling hardware accelleration of interface, adjusting gpu memory useage, every codec under the quicktime wrapper including uncompressed codecs, updating Blackmagic drivers, updating quicktime, limiting how many processors Windows 7 64bit can see, resetting AE preferences. I even installed After Effects clean on my second boot drive for gaming with no plugins or other apps, same issues. Have discussed this heavily with tech support at Adobe and they are working on it for a few days before getting back to me. When I got off the phone the tech was of the mind that I have too many cores for the Quicktime codec to handle.
My system :
Windows 7 64bit
Dual Xeon E5-2687W: 16 Physical cores and 32 cores with Hyperthreading
32GB 1866 DDR3
3xNvidia GTX 680 4GB cards
SSD boot and seperate SSD media cache drives
8TB internal SAS RAID 5 using a ATTO card
Blackmagic Deckline Extreme 3D+ card
Any help or thoughts would be greatly appreciated as this is a huge boon to my workflow. Having purchased a $12K system for grading and rendering....not being able to use the ram preview in AE with multiple cores is a huge inconvenience.

Here is the requested taskmanager screenshot. As my test comp only has a single duplicated quicktime in it, it renders too fast to really catch the AE instances doing anything. So this is from a heavier comp. Settings are as pictured above with 3GB per core using 8 total cores of the 32. It did flash the bars.
Here is what I tried tonight:
- Followed the link on Quicktime having trouble with too many processors. Using MSCONFIG I dropped the recognized Processors to 21, 16, and 8 and tested all three settings. Each had the flashing bars issue. Again as usual, at random, sometimes 3 previews before showing up, sometimes the first preview run. I have noticed that the ram previews that take a little longer seem to be clean. Then sometimes it seems to fly through the preview, grabbing large chunks on the green progres bar above the timeline, or many little chunks very quickly....these are usually the preview runs that will show the flashing bars. I make a point of purging the cach between each one so it doesn't remember, plus I have disk media cache off, but sometimes I get the feeling it's remembering bits.
- I removed all the Quicktime Components from the QTComponents folder and tested it. Flashed the very first run without any quicktime components.
- Followed the Firewall or TCP instructions and made sure everything was allowed through ZoneAlarm. However I could not find the QT32 Server listed anywhere or figure out how to add it. No matter because I closed and force quit all of the firewall processes as well to make sure. Still flashed.
- I followed all the advice on the landing page for Quicktime-related problems
- I also tested out ram previews again thourougly with the same clip but converted to a Tiff sequence. No matter what I tried there was never any flashing in the ram preview with tiffs.
- I also re-tested the clean render output. Made a ram preview with the flashing bars, then without purging rendered it out to a quicktime file and there were no bars at all in the rendered output. I even tried duplicating this render output 6 times in the render queue and rendered them all at once. Not a single one had a flashing bar frame. I even played all 6 1080P uncompressed 4.2.2 YUV 10bit pieces off the RAID with no dropped frames or hichups.
- Killed every process in the taskmanager but for essential windows processes and the flashing bars were still present
- Set the priority to Real-time for every AE process including Adobe QT32 Server, Dynamiclinkmanager, and all the AE processes. Still flashed.
I am now considering disabling two of my GPUs in the device manager. However I'm a bit worried about disabling the wrong one and being locked out. Any thoughts? Is the computer to powerful for some process somewhere? Why only in RAM preview? Thanks again.

Ram Preview only renders about 60% of work space then stops...

Any ideas. The green line renders normally but stops about 40% short of the end of the work space.
Thanks for any help

RAM Previews use available application RAM to store rendered frames. Once all the RAM is full, the preview render stops. The maximum RAM available to AE on any platform is 4GB, but may be less depending on your hardware, your OS and various other factors.
Try reducing the preview resolution to increase the amount of time previewed.

Another RAM preview question. CS6

Hello everyone! I am currently working in After Effects on a video that uses an evaporation effect. When I use the RAM preview function only about 200-250 frames load out of 1200. At this point After Effects stops loading a RAM preview and just plays the few seconds of video it has loaded. I am trying to watch the entire 12 seconds of the evaporation effect.
I then tried to use footage that has no effects added to it, and the same thing is happening. I recently cleaned my disk cache, and this problem started happening. I feel like that is a coincedence though.
This problem was not happening a few weeks ago and after searching the forums I have not been able to find a solution that worked. Thank you for any helpful responses you can give.

Why does RAM preview only play part of my composition?

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???

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?

After Effects cs6 RAM Preview NOT REAL TIME

So every time I create a new composition at 59.94 fps and insert a video file (.wmv file usually) that is as well at 59.94 fps and I try to RAM Preview just the raw footage it says the same thing every time (the picture). I always change the quality to Quarter and I tried the 33.3% zoom and it doesn't help. I have the Render Multiple Frames Simultaneously box checked and I'm using 2 of my 4 CPUs and 6.4 GB of RAM available for AE... Any help?

Are you doing a RAM to preview or just pressing the spacebar? Are you new to aftereffects?

CS6 RAM preview short and "needs 2 or more frames" errors

Hello everyone,
I've been researching this one for over a week now and still haven't found a solution. The short story it is that my RAM preview is limited to only a few seconds regardless of work area, but I've got over 4Gb of RAM available and open for use. CPU is barely being used as well. I'm also intermittently getting the "After Effects Error: RAM Preview requires 2 or more frames to playback," which confuses me as I have 4Gb or ram available. RAM is still close to 4Gb during and after preview. This has been a repeated problem, not matter how many times the memory is purged, the RAM is free'd up with the Memory Clear App (as recommended in previous threads), or the computer is restarted. Memory and Cache have been optimized for best performance as well. Also, final renders are fine and have no problems. It's only with RAM preview and previewing the project that I'm having trouble. It seems to me that the project is being bottlenecked somewhere but not sure where or how. To open, here's the system I'm running it on. It may not be a brute but it should be enough to handle the work.
System:
Program: Adobe After Effects CS6 (11.0.4.2
System: Mid 2010 iMAC, 27-inch
Processor: 2.8 GHz Intel Core i5
RAM:   8GB 1333 MHz DDR3 (two 4gb cards)
Graphics: ATI Radion HD 5750 1024 MB
Software: OS X 10.9.4
Hard Drive: Western Digital WD Green 2TB Sata drive
                    -6.0 Gb/s 3.5" Hard Drive
Project Specifics: (Has happened across other similar projects)
Project: Educational video with graphics, simple animations, and link to Premiere Pro timeline.
               -33 layers (most are highlight boxes and animated arrows)
                         -13 small PNG images (Arrows and simple graphics with 1 3D layer)
                         -7 Short Compositions
                         -7 Text Layers
                         -5 shape layers
                         -1 Premiere Pro Timeline
Composition Settings: 1280 x 720 at 23.976fps
Project Location: Company Server
Problems
-Ram preview only renders a few seconds, regardless of Work Area or "From Current Time" enabled.
-Fairly frequent, "After Effects Error: RAM preview requires two or more frames to playback."
-Scrolling through project is very pixelated.
When Problems Occurs: When trying to perform a RAM preview.
Attempted Solutions:
- Use of Memory Clean App to open up more RAM. (Makes little to no difference when problem is at peak.)
- Shut down and restart computer (Does work for a short time but problem reappears within an hour)
- Closing all apps and running just After Effects. (Little to no difference)
- Turning off motion blur, turning on 3D draft and using Proxies to simplify project. (Little to no difference)
- Purge: All Memory. (No difference)
- Stopping any unnecessary processes in Activity Monitor. (No difference)
Additional Information:
-Projects seem to take a little longer than normal to open. (1-2 min max.)
Thanks in advance for any support on this issue. It's been quite a stressful timesink.

Unfortunately the problem has come back again after an hour of use this morning. To show how much RAM I have available at the time the issue appears, I've included the Memory Clean window showing 4.44GB of ram available at the time of incident. It first happened a few minutes ago with roughly 1GB available, so I and purged all memory in After Effects and cleaned the RAM with the Memory Clear app, but still no such luck. I've been working with the same actions and material all morning so nothing new was introduced to the project when the error occurred. The work I was performing at the time was animating highlight boxes over a screen capture, but again it seems to happen regardless of what I'm working on. I'm going to restart the computer and see how long it makes it before needing another reset. Any other ideas as to what it could be? Also, if there's any more information that might be helpful to solving the issue please let me know and I'll be happy to share. Thank you again for the support!
Szalam, thank you for the link. I had been to the page previously but am going back to watch them again to see if I missed something. If it is a bottleneck, I'm not sure where it could be as of yet.
And just to make sure I'm not making any other simple mistakes VVV

Mac Pro has problems rendering and RAM previewing in Adobe AE

I've been using Adobe After Effects 7 and I have a 3g new Mac Pro. It's a great computer, really fast with Final Cut Studio Universal, etc. and when rendering sequences in FCP the program doesn't quit. BUT, when I'm trying to RAM preview or render a composition in Adobe After Effects the application will quit unexpectedly everytime. I found that it would only quit when the composition was over approx. 30seconds, but I've used an eMac that never had problems rendering much longer clips. The fact that the program quits after a certain amount of time makes me think it is an issue with RAM availability to the program, as in a conflict with the program, and the new intel-based Mac Pro. I've asked around on the Adobe website but there is no specific solution. Has anyone heard talk that the intel-based Macs or new OSX, are conflicting with Adobe applications, etc?

Mostly correct, Jim. Photoshop CS3 (UB) Beta is available for download and a time-limited license to CS2 license-holders. The time-limit is unspecified, but Adobe says it will end when CS3 is released.
All good reports the last time I checked on various fora.
(CS3 install does not overwrite CS2, so in case Adobe releases CS3 and pulls the plug on those time-limited CS3 Beta licenses, you'll still have CS2 to limp along with until you receive 3.)
CS2 seems to work fine on an Intel Mac, though slower because it's running in Rosetta. Heck, I'm using CS without difficulty, other than the slowness.
However, all that doesn't help the OP with AE, which isn't scheduled for a UB release until mid-2007, IIRC.

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?

(MP) RAM Previews haven't worked reliably since February

I was really hoping the CC 2014 update would address this issue I've been experiencing since February, but the issue remains and if anything is worse than ever. Long story short, sometimes RAM previews work as expected (as in I press the RAM preview button and After Effects actually generates a RAM preview) and other times pressing the RAM preview button results in delays ranging from several seconds to several minutes or simply never doing anything at all. Sometimes, it's the horrendous "Initializing Background Processes this may take some time..." message, and other times it's "Rendering frame (MP) 2 of XXX requested" followed by...nothing ever happening. Try to imagine how frustrating this can be when on a deadline or with clients in the room.
I'd read that the size of your project can be a major factor in such delays. Well, I just started a brand new project that contains exactly one asset (a 1920x1080 22-second H264 video file), added a couple filters and clicked RAM Preview, only to be met with the "Rendering frame (MP) 2 of XXX requested" message and no frame ever rendered. Activity monitor showed 8 red "aeselflink (Not Responding) processes that didn't go away when I quit After Effects. I quit After Effects, logged out and back in, relaunched the project and RAM preview worked as expected. As I said, completely unreliable and unpredictable.
I need RAM Previews to work all of the time, not some of the time, and I need them to work with multi-processing enabled. I realize that disabling multi-processing for RAM previews resolves the up-front delays - but using only one of my eight CPUs is NOT a fix (considering each RAM preview would therefore take 8 times longer). Nor is rebooting and relaunching After Effects a dozen times per day a real solution, right?
My system is a 2013 New Mac Pro, 3Ghz 8-Core Intel Xeon E5, 32GB RAM, Dual D300 GPUs running Mac OS X 10.9.3 and purchased in January; I don't recall experiencing the issue prior to the February 13th AE update). The issue is present with both Adobe After Effects CC 12.2 and Adobe After Effects CC 2014 13.0. My Memory and Multi-Processing Preferences are in the attached image. I truly appreciate any help that can be offered. Thank you!

Rick, please read my third paragraph. While yes - disabling multi-processing helps, effectively turning my computer into a one-processor machine instead of an 8-processor machine is not a solution.
And I experience these long delays even with NO filters or 3rd party effects whatsoever. I just rendered an animation that was nothing more than a couple sliding illustrator layers with a 3D camera move and the render took 3 full minutes to get beyond "initializing background processes, this may take some time...". This just after a fresh launch of Adobe After Effects.

Ram preview oddity

hi,
i'm coming over to motion from after effects, so apologies if this is a standard question...
but my ram preview only gives me about 6 seconds, regardless of the resolution or scale. if memory serves correct, in AE you could get more time in ram preview by reducing the resolution or scale factors. in motion, i get the same amount of frames in ram preview if i'm at 50% half res, as if i was in 25% quarter res.
macbook pro Mac OS X (10.4.8)

Hi Michael
Please check your in-/outpoint markers. Motion does RAM render what's between the markers on your timeline. Also check your project duration (bottom left).
Try this:
If you have 12 sec long project that plays from start to end (unrendered), then do the following:
- Deselect everything on stage
- Hit the home button
- Hit the i key (for inpoint)
- Hit the end button
- Hit the o key (for outpoint)
- Command-R for RAM review
You will see the green bar increasing from home to end (or i to o)
Cheers
Hisham
