Painfully slow ram preview in AECC 2014

I am having problems with ram preview in AECC 2014
I have a project where I am getting 2 secs of footage rendered in 12 secs in AECC 12
The same 2 secs of footage on the same computer with the same settings in AECC 2014 is taking 2mins 21secs
Anyone got any suggestions?

Not without more info.
What format and codec is the footage?
Screenshots of your render settings in both CC and CC 2014 would help.
Check to see if ray-traced rendering turned on in your comp in CC 2014?

After effects slow ram preview hold for 4 seconds before starting

Hi I have upgraded from After effects CS5.5 to CC 2014 , and I notices that when I want to make Ram view by hitting 0 num pad key , it pauses for 3 or 4 seconds before it start caching , and it become really annoying if you want to ram preview every 1 min , I tried playing around with the Preferences /Memory/ Ram reserved for other apps , but no good .
That was not the case in CS 5.5 , is it was starting caching as soon as I hit the 0 key .
I am working on Mac pro workstation , quad core intel xieon 2x 3.2 Ghz Mac Os 10.7.5
Thanks

I am guessing that you have MP rendering turned on in the preferences. Please turn it off and test again.

Slow RAM Preview in CC, any suggestions?

I am running my CC on a Windows 8.1 OS, with 24 GB RAM, an EVGA GeForce GTX 760 4GB graphics card, and i7 3570k Quad Core 3.4GHz processor. However, I am still experiencing an issue with struggling RAM preview. I've also altered the cuda supported cards in the Premiere file, so as to allow my GTX 760 access to the softwares, and still a slow rate of rendering speed. Therefore, I'm wondering if you would happen to know what the issue could possibly be, or if I should purchase new hardware or something. Any feedback would be appreciated.

Help>About will show you the version number.
Do you accidentally have the ray-traced renderer turned on for your composition instead of the standard renderer?
Do you have Depth of Field turned on for your camera?
Tutorials often speed up RAM previews to prevent boredom on the part of the viewer.
The size of the emitter is unrelated to the processing power it takes. What matters is how many particles are being created

After Effects uses the GPU for very little. See here: GPU (CUDA, OpenGL) features in After Effects
Side note: The ray-traced renderer is now considered obsolete, so if you had not heard about it before, don't get all excited and start learning it. Learn this instead.
CPU and RAM are the two most crucial things for AE. This page might help: Optimizing for performance: Adobe Premiere Pro and After Effects

Very slow RAM preview (novice user in need of help)

I am looking for some recommendations for hardware. I had a Mac Pro (8 core with 8MB RAM) and it rendered at the same speed as my IMAC. I am using AE CS5 and the trapcode 10 suite, in my comps. A ten second comp will take over 10 minutes to RAM preview, it takes 4-5 seconds for each frame, frame by frame. I tried enabling and disabling the (multiple frames simultaneously) function, as well as experimenting with the number of cores for AE setting. Any hardware recommendations would be gratefully appreciated. If you could share your hardware configuration / AE settings, It would be much appreciated.

See this page for information and recommendations about memory and improving performance in After Effects.
Recommendations in general are difficult because every composition and computer are different, as are people's preferences regarding rendering speed versus length of RAM previews, what other software they want to run at the same time, et cetera.
But, I'll make a very broad recommendation:
For HD-sized movies, you want to have 3-4GB of RAM installed per processor. So, for a quad-core with hyperthreading (which effectively has eight processors), you'd want 24-32GB of RAM. This describes my personal computer, by the way, so you know that I have put my personal money where my recommendations are.
Don't neglect hard disks. You need to have more than one hard disk. Sooooo many people complain of poor performance and fret about RAM and CPUs, and then I find that they're running their OS and applications from the same single disk that they're reading source files from and writing output files to... or their external disks are over a USB connection. [*shudder*]
BTW, particle effects like Trapcode Particular take a long time to render. That's just a fact of life. You may make them faster, but you'll never make them fast.

AE CC 2014.1.1 the plague of "ram preview needs 2 or more frames"

As i said abot Premiere CC 2014.1, for me AE CC 2014.1.1 is the worst version of this sw ever on my system. Specs:
i7980x
GTX680 4GB
24GB ram
Asus P6T deluxe mobo
2 SSD Intel, one for AE cache
I'm experiencing continuos crash from AE. I'm on a big project, as always, and performance is terrible. After a bit of time of working AE became terribly slow. The "blu" bar under the preview window start load again and again. I move the mouse, loading, i scroll the window, loading, press caps lock to stop the preview....loading. This is the sympthon. After this kind of wierd performance i know that my ram preview will not start again. The infamous message will pop up and doesn't matters what i do, purge, format ram or whatever. the only way is to close AE and reopen it.
Now...i'm using AI files or PSD files, so i've to run AE and Photoshop or AI all toghether....after some minutes...the bar loading, the performance slows down and the message pop up again.
The ridicoulous fact is that when i render the project i have the ram usage at 19% and cpu usage at max 60%. So my renders are really long (about 10hr for 2 minutes of animations), but my system is sitting there doing nothing. Really odd...i can use 12GB of ram and half of the cores at this point, doesn't matter for AE performance...

Right! It's got a little bit worse... After the 'RAM preview needs 2 or more frames' window I purged then restarted and all was back on track for about 5 minutes, then it happened again and then the following series of warnings have locked AE in a cycle of warnings...
Below is the series of warnings I've just received followed by my memory and cache settings and then the memory left on my computer.
then
my memory settings
my cache settings
and the memory left on my computer
The file is 'just' a series of After Effects solids with masks (about 40), rigged together with Duik IK (not the puppet tool thing just the one that links layers together) and some wavs for the sound file.
Like I say I've probably done hours of lipsyncing over the last 15 years with far far heavier files (using HD footage and a far bigger comp with psd files) and I certainly haven't had this kind of persistent problem and it's only since I installed CC2014 last week...
grrrr and arrrrgh

RAM preview needs 2 or more frames to render playback - AE CC 2014

Hi everyone,
I'm having major issues with AE CC 2014 (13.0.0.214) on both Mac and Windows.
The dreaded RAM preview bug has been appearing at my office and home computer spanning 4 computers in all (so far) and it's really impossible to work in AE CC 2014 for more than 20 minutes without having to restart the app. I use a couple of plugins and scripts on my work computer (none of which are active in the scenes), but the same bug happens on my coworkers' computers despite being barebone AE. It also occurs on my Windows 8 PC at home.
What happens:
My co-workers and I animate, often with illustrator files, shape layers, and text. I animate, RAM preview, and repeat. After a certain point I'm no longer able to RAM preview without the warning message appearing about RAM preview and 2 frames. In addition, scrubbing through the timeline is very slow.
What I noticed:
Watching my activity monitor my memory usage builds up as I do my RAM previews and stays at the that peak level. Each time I ram preview or scrub through it increases more. Once it reaches the allocated memory for the program, in this case, 12 gigs, the warning appears and I have to restart to RAM preview again. Purging memory does not work and my memory usage is still maxed out.
More Info:
It's happened on my Late 2014 MacPro, a 2013 MacPro, and 2012 MacPro. All running OS 10.9.4. And my i7 3770 16GB PC at home.
My Specific work computer specs 3.7 GHZ Quad-Core Intel Xeon E5. 16GB 1867 MHz DDR3 ECC.AMD FirePro D700 6144 MB. OSX 10.9.4 (13E28)
No firewalls running
I've tested it with all other apps closed and still am able to reproduce it
No issues with AE CC 12.2
Not using Ray-trace 3D in any compositions
Memory-multi-processing disabled. Although same thing happens when enabled for renders and when also enabled for RAM previews.
Any help would greatly be appreciated.

I'm having the same issue, with the same symptoms. My Mac is older, but still ran CC with no problems.
AE CC 2014 (13.0.0.214)
Early 2009 Mac pro (4,1)
Processor 2.66 GHz Quad-Core Intel Xeon
Memory 6 GB 1066 MHz DDR3 ECC
Graphics NVIDIA GeForce GT 120 512 MB
OSX 10.8.5
I have tried disabling all plugins and attempting a normal workflow of editing 720p footage together, and adding solids and custom shape layers. Basic effects like fast blur and some motion blur but nothing too crazy. A memory dump doesn't do anything to solve the preview issue, and after a program restart everything works fine for a few more RAM previews. I also had no issues with the previous version of after effects CC. I always keep multiprocessing off, no ray trace 3d and I still get the issue after a system reboot and no other applications started (even after removing all startup applications from my preferences).
As a last ditch, I have removed any and all antivirus software and disabled all firewalls as I saw this as an answer to a previous but similar problem.
I too would love some help, as this is beginning to be a costly time waster. Let me know if you receive an answer for this one.
My apologies if this is in the wrong spot, I am new to the community.

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.

CS5 RAM preview is slow if I do other things while it's building

Good morning!
I'm experiencing a strange issue. 1080/29.97 comp on an 8-core w/ 16GB. Multi-proc rendering is off.
If I RAM preview the comp (800 frames or so) and wait while AE builds the RAM preview, it plays back fine & at speed.
If I start the RAM preview, then go work in Photoshop while it's building, then return to AE and attempt to play it down, I have the green bar like a normal RAM preview, but it plays very slowly -- almost as if it's re-rendering every frame (actually slower than if I just hit spacebar to render&play on the fly).. maybe 1fps. If I stop and play those frames that it's slogged through, they then play normally.
Is it possible that RAM previewing while I'm using another app (e.g., Photoshop) is resulting in the frames being written to swap disk or elsewhere so that they're being re-read into RAM when I actually try to play it? Disk caching is disabled in the AE Prefs, but...?
Thanks in advance for any ideas -- very annoying.

Yes. That is possible.
Be sure that you're reserving enough RAM for other applications.

Editing pdf files in Preview painfully SLOW with mavericks! Why? How to fix?

Editing pdf files in Preview is painfully SLOW with Mavericks! With mountain lion everything was so smooth .... Why? How can I fix this?

I stopped using preview. Adobe Acrobat Pro is running fine ... this is not a solution to the problem though. The question remains open: why is preview not running as before?
Why did I upgrade?!

Why is RAM preview crashing my After Effects CC 2014?

Using Windows 7 x64
After Effects CC 2014
I'm getting numerous crashes when using the RAM Preview.
Until my current project started getting more complicated all was good - no crashes. As I've added more assets to it, it's become very unstable.
When I click the RAM Preview button it'll either crash immediately, or succeed. If it actually starts, it's fine. But more often than not it just crashes the whole program immediately.
How do I solve this?
Is there a checklist I can use to check for possible issues?

Right, right. Vague info I know, but I was hoping for a checklist of common culprits I could eliminate one by one. Very new to the world of video.
I'm running:
Windows 7 x64
Intel i7-3770K CPU @ 3.5GHz
32GB RAM
GeForce GTX 780
Doing a 720p project, but using mainly 1080p footage.
Video files used are .MP4 and .MTS format.
Using various effects. Mostly simple stuff.
Plenty of sound effects and music as well. All .WAV format. No MP3's (I heard AE hates MP3 format).
I don't get any crash info. The entire program freezes until I kill it manually.

After Effects 2014 CC Ram Preview Issue

Ever since I upgraded to CC 2014(from CC) I have been experiencing an issue. My RAM preview will start somewhere in the middle of my in/out points. I have to wait for it to loop to see the beginning. I have tried checking/unchecking "from current time," I have tried cycling through the playback options, and I have tried clearing my cache. Nothing seems to work. Any help would be greatly appreciated!

Warning "RAM Preview needs 2 or more frames" after scrubbing audio in After Effects CC 2014 (13.0)

The After Effects team are investigating a bug in After Effects CC 2104 (13.0) where a memory leak occurs while scrubbing audio (holding down the CTRL or Command key while scrubbing). This memory leak can eventually consume all free RAM, which can lead to the warning message "After Effects error: RAM Preview needs 2 or more frames to playback" when you try to initiate a RAM preview.
While we investigate this problem, you can avoid the bug and memory leak by not scrubbing with audio. When the problem occurs you can resolve it by closing and restarting After Effects.

AE CC ram previews very slow - no GPU support? Newbie trying to become not newbie, falling at first hurdle...

Hello. I'm currently trialling After Effects CC though Adobe Cloud. But I've hit a snag immediately.
I have an HD video edit in Premiere Pro which I want to dynamically import into AE to work on some bits.... I have imported the project file into AE, it seems to open just fine but the playback is intensely slow!
I have an uncertified GPU - a Nvidia Geforce gtx 460 - too old? I was expecting it to help out a bit, I'm not doing anything too badass, just colour correcting a bit of HD footage.
My processor is an i5 3.4ghz 4 core.
Perhaps I'm missing something fundamental here!? Please tell me what I'm completely failing to grasp
Thank you for your time,
Tony

Yup -- you're misssing a very basic item: AE doesn't work like Premiere Pro. It's not anything like PP, and it doesn't behave like it.
One way is the method you need to play video. Space bars just don't work. You need to do a RAM Preview -- hit the zero key on the numeric keypad, let AE render the frames it can, and then it plays them back as fast as it can.
