Ram preview not playing from first frame

Anyone else having problems with Ram preview playing back from a different spot in the timeline OTHER than the first frame? I have seen this happening consistently since the latest update (2014.2). I checked my preferences, and made sure nothing is accidentally selected to play from the last keyframe or something odd. But no. I am on a Mac Pro, running Yosemite, I googled this, and haven't seen anything. I haven't trashed my preferences yet, because I'm not sure it's a preference issue, and god...if I have to rebuild my render setting one more time...
So to give you more detail.
- I hit "0" on my number pad to launch a ram preview
- It LOOKS like it's rendering each frame in order
- When I hit "0" again to playback, it starts from a random location usually about 2 - 5 seconds from the beginning of the timeline.
- It will loop back and then play from the start of the timeline.
It's not using the current time indicator line or anything that would make sense. It's random, but near the start. I suspect it's pulling keyframe information from a nested pre-comp and using that, but there is not a keyframe in the comp I'm previewing.
I also do not have the "From Current Time" checked box in the Ram Preview options, and there are 0 skip frames in that setting as well.
If anyone has any ideas what this may be...I'd appreciate it.

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!

HD RAM preview not playing in realtime through Blackmagic

I've recently upgraded one of my company's Blackmagic Multibridge Pro NLEs to CS5:
PROBLEM:
AE CS5 does not play realtime RAM preview of HD1080 video when displayed through the Blackmagic video output (even as low as 1/8 resolution).
INFO:
1.) Lowering resolution (even down to 1/8) does not help.
2.) Matching scale % to resolution % does not help.
3.) Doing #s 1-3 in combination gets very close to realtime, but CS4 did not require all of this.
4.) If I switch AE output to "computer monitor only" I get realtime.
5.) SD comps played through Blackmagic output achieve realtime.
In CS4, HD Blackmagic output WAS realtime. I have made all memory/multiprocessing settings match the CS4 configuration, but this has not helped.
Also, both AE and the Blackmagic driver are the most current version. I have no desire to revert to CS4... Anyone have any ideas?

To answer my own question:
I lowered the project's color settings to 8 bits per channel--and now all HD RAM previewing (even at full resolution) seems to be playing back realtime!
Hope this thread can be helpful to anyone else experiencing the same issue.

After Effects RAM Preview not showing first 50 frames or so - Mac OS

So I'm on a 2012 iMac, and when i RAM preview, it plays audio but video does not show until about 50 or 60 frames in, its like a glitch or lag thats started recently, so it makes ram previewing from a certain time a real pain as i then miss the exact part i want and it c matches up with video a second or two later, i can't find any solutions, please help!!

As Andrew says, Adobe and Apple are working on figuring this bug out. See the known issues section of this page: After Effects good to go with Mac OSX v10.10 (Yosemite)
If you let the RAM preview loop at the end of its playback and play through again, it should be smooth and issue-free.

Made preference changes, but still getting the Ram preview needs 2 or more frames to play back.

I'm new to After Effects CS6 and am working on a very simple Kinetic Typography project. I don't have a lot of memory, but this is a really simple project, so I'm wondering if maybe I'm just not using the work area correctly. Every once in while I can get the project to RAM preview, but only for a few seconds. Most of the time I get the "Ram preview needs 2 or more frames to play back" error message. I have pasted my sytem info and setting info bleow. Thanks for any insight!

RAM preview needs 2 or more frames error

Good Morning,
I have just encountered this error for the first time since i started using AE about 6 years ago.
I am running a PC (windows 7 pro), i5 2.90GHz 64-bit OS, 16GB RAM, and 1 GB Graphics card, dedicated 1TB HDD for Cache. Creative Cloud subscription.
I had no problems up until the update to 'After Effects CC 2014', since this update i cannot generate a RAM preview. I have read countless forums and i have followed previously suggested solutions (purge, remove VCReflect plugin, started AE as administrator etc), to no avail.
Any suggestions will be welcomed.
Will

The "RAM preview needs 2 or more frames to play back" message usually means 1 of 2 things. Either:
You have requested a RAM preview of only 1 frame.
There is not enough RAM available to generate more than 1 frame.
Regarding the first possibility, make sure that your comp is more than one frame long, and that your work area bar is set to more than one frame. Also make sure that in the Preview panel the From Current Time option is not enabled, if your current time indicator is on the last frame of your comp. In these cases the message is saying "You don't have more than one frame for me to play, so using RAM preview doesn't make sense: this single frame is already on screen and already cached!"
Regarding the second possibility, there are a number of contributing factors. Generally, make sure that there is available memory for After Effects to use, which you can check in Activity Monitor or Task Manager. If you don't have much free memory: use the Edit > Purge > All command, close other applications and/or restart After Effects or your computer. If you appear to have lots of free memory, start breaking down your comp, turning off effects and layers (including cameras and lights) until you can get a RAM preview without the error message.
Effects, in particular, can consume large amounts of memory, such as particle effects or effects that grow the layer bounds to very large sizes. If After Effects can't generate more than one frame for such a layer in the amount of available memory, you may get this error message.
If you're still having trouble, test by building simpler comps just to verify you can RAM preview anything, such as an animated shape layer or text or a piece of footage with no effects applied to it. If you need to post back to this thread, describe the contents of your comp, including the comp settings, layer types, effects applied, etc. Screenshots and screen capture videos are always helpful.

After Effects CS6 error: RAM Preview needs 2 or more frames to playback - any ideas please?

Hi everyone,
I'm running After Effects CS6 (11.0.4.2) on a MacBook Pro 2.8Ghz with 16GB RAM (Mac OS 10.9.4)
As a test, I created a 3 and a half minute Sequence in Adobe Premiere CS6, and then imported this into After Effects CS6, and placed it on the AE timeline.
This footage involves a couple of 1920x1080p footage movies, some psds and a large number of JPGs exported from two videos arranged as a sequence in two layers in Premiere, one on top of the other. So all in all for a Premiere / After Effects file I'd say it's reasonably heavy.
I then did a RAM Preview with Multiprocessing switched off - the 3 and a half minute sequence loaded into RAM, taking about 1min 30seconds, and played back in realtime at 25fps. This worked fine with 3,4,5 and 6 GB RAM available to other applications in the Memory Preferences. All things considered I think this is quite good. I can make changes, reclick the RAM Preview icon and my changes load into RAM and it previews ok.
My only 'complaint' is how long the RAM Preview takes to load up the whole thing.
I've been reading up on Multiprocessing and decided to try this to see if I can speed up the time it takes my RAM Preview to load up.
So I looked at some recommendations from Adobe and read information on various forums including this one.
My settings in the Memory Preferences are currently
• 6GB reserved for other applications
• Reduce cache size when system is low on memory - unticked
• After Effects Multiprocessing - ticked
• Installed CPUs (processor cores) - 8
• CPUs reserved for other applications - 6
• RAM allocation per background CPU - 3GB
• Actual CPUs that will be used - 2
This combination takes about 25 seconds to load up my 3 and a half minute sequence which I thought was pretty amazing.
I then pressed the stop button and then the play button - so now just playing the sequence briefly.
And also added a new layer - into the timeline - just a simple shape.
Then I tried a RAM Preview again.
I found I could load up part of the sequence but not load the whole thing into RAM.
I kept trying to get a RAM Preview and got this message
"After Effects error: RAM Preview needs 2 or more frames to playback" which seems to prevent RAM Preview from working.
Eventually I quit and restarted After Effects and the problem went away temporarily and then came back when I tried again.
I tried various changes to the Memory Preferences - trying 3GB available for other applications. This gave 13GB of my 16GB RAM to After Effects.
This made it take slightly longer for the After Effects error to appear but it still appeared.
I tried ticking Reduce Cache size in the Memory Prefs - the After Effects error still appeared, so having read this is supposed to make the issue better I now leave it untucked, but as far as I can see ticked or untucked, it makes no difference, the problem remains.
I've since tried -
Making 2,3,4,5 and 6 CPUs available for other applications.
Changing the Background RAM allocation per background CPU to 0.75GB, 1GB, 1.5GB, 2GB and 3GB
Lots of combinations.
But in the end, I always get the "After Effects error: RAM Preview needs 2 or more frames to playback" error.
It might take less or more time for the message to show up, depending on the combination of settings, but in the end I always got the same message appearing.
And I notice that I can RAM Preview less and less of the timeline. i.e. it becomes more blue than it does green and will load in only a small section of the timeline as opposed to the whole thing.
Reading further, I tried Edit > Purge > Image Cache and Edit > Purge > All Memory but still get the error message.
I also tried ensuring there were no other applications running e.g. Safari or Chrome or Firefox. And certainly not Photoshop or Premiere etc.
Reading even further, I tried two Memory management applications - 'Memory Clean' and 'Purge.'
Neither has had any effect - the After Effects error still appears.
Then I went back into the Memory and Multiprocessing Preferences.
I unticked Render Multiple Frames Simultaneously. And now the RAM Preview loads the whole 3 and half minute sequence in entirety, taking about 1 and half minutes to do so. It's working as perfectly as if I'd just quit and re-opened the application.
Then I went back into the Memory and Multiprocessing Preferences.
I reticked Render Multiple Frames Simultaneously.
The chose Edit > Purge > All
And tried a RAM Preview again. It loaded up in 25 seconds, but then, as previously, the error message came.
I tried Edit > Purge All - no effect.
And I tried going into the Media and Disk Cache Preferences and clicked Empty Disk Cache - still the problem remains.
I understand from my reading that After Effects CS6 11.0.2 was intended to fix this issue but I'm on 11.0.4 and as far as I can tell, I still have it - assuming it's the same thing.
As far as I can see, not using Multiprocessing allows me to work without these errors but take a bit longer to load the RAM Preview.
However I'd like to be able to use Multiprocessing as it seems it can potentially speeds things up quite a lot. I realise I could just not use it and AE would work, but I'd rather be able to make use of a feature of the software if possible, especially if it will speed things up and make optimum use of the my computer's hardware.
I've downloaded a trial copy of After Effects CC 2014. I'm still testing it but as far as I can see the RAM Preview error appears in this version of AE as well, but can take bit longer to show up in my experience.
Thanks everyone - if anyone has any thoughts or advice I'd appreciate hearing your opinions.
Kind regards,
John

You need to have much more RAM reserved for other applications and more CPUs reserved for other applications. Your current settings are crippling your performance.

After you have adjusted your settings according to the recommendations on those pages, restart your computer and try again.

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 not working correctly

On one machine here, when the artist goes to do a ram preview, they only get grey frames in the comp window. Either that or they get a freeze of the first frame in the render region, but no motion.
I have tried deleting prefs, zapping Pram, deleting the cache, purging memory. turning open GL on and off, all to no avail.
Any thoughts?
Thanks in advance
Sam DeWitt

I'm not sure if RAM issues really show up during normal work. In most cases the operating system will constantly rearrange the memory allocation, so it may never touch upon that one damaged memory block. You wouldn't even know it, if it caused a crash once a week, because it could be anything. I'll admit that it's a far shot, but nonetheless one should not rule out what seems to be impossible at first sight. the only other thing I can think of would be a tool that suppresses screen refresh, which could be some widget ort system extension...

RAM preview needs 2 or more frames, I've got a clue...

After struggling for half an hour or so, I think I'm on the right way to find a solution to this annoying problem. I'm using CS5 on Win7 x64 Ultimate. The problem is that AE cannot starts the ram preview: "after effects error: RAM preview needs 2 or more frames to playback". After having searched among several forums, I've tried all the tips suggested here and there: purged the cache, using a different codec for the clip I was trying to play back and so on., but no luck so far. I've also moved the Conformed Media Cache folders to another folder on my hard disk, thinking that the current ones were full or that maybe I could have some administration problem with those, neither this helped.
Then I've started from scratch and I've discovered that for some reason if I have all the H.264 clips in my project, even if I was using 1 clip only (and it was converted to an AVI clip non compressed used as PROXY) than AE couldn't ram preview my comp. Now I've reduced the project and I'm keeping that clip only in the project and it seems it's working now.
To add more oddness to the story, now it doesn't matter if I use the AVI proxy file or I do turn the proxy off switching to the H.264 file again. It seems it works either way.
Hope this can helps somebody else who's struggling with the same problem...

I have this problem with my supercomputer and After Effects CS5.... it used to work just fine.
I have an i7-980x, 16 gb RAM, Win 7 home premium, 2 ATI Radeon 5850 each with a gig of video RAM.
I have tried all of the online suggestions, entered a bug report, re-installed AE CS5 (Prod Premium Suite), then updated again.
All I get is the same error report. VERY Frustrating.
Disabled all firewall, antivirus.
Made a little comp of a white box changing position from frame 1 to 200,
Still won't RAM preview.
Please help!

RAM Preview - Not in realtime

Hello
On my computer, whenever I try to playback somehting to see a preview, it plays at 17 frames per second, with red text saying, Not in realtime. Is there anyway that this can be remedied?

Make sure you are depressing the Zero key for ram preview. I bumped into this the other day because I had selected AJA Kona as my display option in Preferences. When I switched it back to Computer it played back in real time. The other reason might be a very complicated sequence on a computer with slow processers or not enough ram. You always need to share the details of your system when asking questions like this so folks know what you are using.

"After Effects error: RAM Preview needs 2 or more frames for playback"

i7-980x, Win 7 64, 16 gb RAM
I STILL get the "After Effects error: RAM Preview needs 2 or more frames for playback" and max allowed memory of 0.4, despite max usable memory listed as 15.99. Sometimes if I run Premiere Pro, PS, AI, 3-4 QT movies and 5 or six other programs simultaneously, after effects will recognize Premiere Pro and allopw me 5-6 gigs active memory, but this can take an hour or two and is hit and miss.
VERY FRUSTRATED here.
This happens with and without the firewall turned on.
Please help

I get this error message when I accidentaly move my CTI (Current Time Indicator) to the end of the composition. If besides also the option "From current time" in the preview panel is checked, After Effects will see that I just marked less than 2 frames namely 1 (from the end frame of my comp to this end frame).
Check therefore where your CTI is positioned!
Also you could have the same problem, if this option "From current time" is not checked, but you have your work areas in- and out-points closer than 2 frames together.
So condensed: Check your CTI and your work area and set the CTI on a previous frame or let your work area start earlier.

Hi,
Try a clean installation of the flash plugin/activeX as follows.
First, download the Flash uninstall utility on the link below and save it to your Downloads folder.
Flash Player Uninstaller.
When the download has completed, close all browser windows, open your Download folder and run the uninstaller. After this has completed, restart the notebook.

After Effects error: RAM Preview needs 2 or more frames to playback when previewing animation video

Good afternoon,
We have an error that is persistent. This error RAM Preview needs 2 or more frames occurs in AE CC often. It happens when we preview what has been animated a few times. Here's all the details below on what we're working on and the computer specs.
Computer Details
Processor 2x2.93 GHZ Core Intel Xeon
Memory 28GB 1333 MHz DDR3
Software OS X 10.9.4
Graphics Card ATI Radeon HD 5870 1024MB Graphics
Project Details
Project usually consists of comps 1920x1080 dimensions RGB
And we're simply animating
Video is always prores 1920x1080
We've added RAM to this comp and still nothing has changed. I saw that the other error for this has been fixed but I'm not sure what's going on in AE for this to continue. Please help !

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.
