RAM Preview with audio?

I'm making a music video, so I need to preview with audio to make sure timing is right................Problem is I can't get the RAM preview to render the audio file......I see the audio mu te button in the preview window but it does nothing when toggled on or off.......How do I get it to render the audio?

I recommend you check your porefs, whether AE even correctly recognizes your audio devices. if you have multiple outputs available, you may switch them around. The same may apply to your system wide settings. If e.g. you have a video capture card and it is your primary device, it may only correctly initialize when the edit program is loaded, but not AE. In addition turn off any fancies like Virtual Surround or such. The additional audio processing may throw things off track as well. For the audio files themselves, make sure the sound is on tracks 1&2, not 3&4. AE only sees stereo on the first two tracks. You may need to split the audio and import it again. Lastly open the Audio panle and see, if you not just have muted everything....

Using GPU preview with AUDIO

Hello people!
I'm newbie here and dont speak english very well!
heheh so....sorry anything
well
Can I fast preview my composition with the GPU (OpenGL), but with AUDIO too?
Because when I preview from RAM, and there is a lot of effects, take too much time to render the video.....!
I want the speed of the GPU preview, with the AUDIO from RAM preview all in one!
heheh
that's it!
thankyou!

There are three ways to preview sound: RAM preview, manual preview (scrubbing) with audio, and audio-only preview. See this page for details:
http://forums.adobe.com/thread/423108
In general, the OpenGL preview in After Effects is only useful as a preview renderer, and most people only leave it on for the OpenGL - Interactive setting.
Using OpenGL for previews and renders is jsut about the last thing that you should be worried about.

No real time RAM preview with Pr CS6.0.1 Open, Real time RAM preview with Pr Closed

When Premiere is closed I see real time performance on RAM previews (29.97fps), smooth UI interaction with and without Fast Draft enabled. When Premiere is opened I get poor fps in RAM previews, lagging UI interaction unless Fast Draft is enabled. Premiere Memory preferences are set to 6GB reserved for other apps, and Optimized rendering is for Memory. It seams that as soon as Pr takes on any processing AE's performance just dies until Pr is closed.
I've tried clearing caches in AE and in Premiere, restarts, and repair disk permissions,
Included is a realtime screen capture of what i'm experiencing, I open and close premiere twice to illustrate that it's not an isolated occurrence.
any ideas?

AE CC 2014 Mercury Transmit Ram Preview with AJA flickers

Hey Everyone,
I have installed the latest AJA drivers and plugins and enabled Mercury Transmit preview in AE but when I render the preview the output flickers. One frame is normal the next is darker, normal, darker etc.
Has anyone got this working yet ?
Nic

Hi Nic,
I'm not familiar with that error message. It's probably generated by the AJA Preview plug-in. Can you post a screen shot?
8-bpc vs. 16-bpc does not always affect the appearance of the comp, it depends on the source material in use and how you are manipulating it. And in any case you can always switch between 8/16-bpc to get better performance when necessary. Keep in mind that switching color depths will invalidate any cached frames.
Some facts about RAM preview playback performance with video preview in After Effects:
Enabling video preview of any form uses the CPU and memory resources of your computer, and when these are in low supply can eventually result in slow frame rates during RAM preview playback. This is because as the frames are played they are transformed on-the-fly (no caching) to the format of the video preview device. The higher the memory requirements of the frame (resolution, frame rate, color depth), the sooner you'll see the playback frame rate slow down. After Effects does not have the option of dropping frames during playback to maintain playback speed, like how Premiere Pro does.
The AJA Preview plug-in does this frame transform more efficiently than After Effects, because AJA has optimized their hardware-based playback pipeline to perform these transformations. It can still eventually be impacted by performance issues. Also, the AJA Preview plug-in currently has some limitations with scaled comp resolutions and color management, so there may be times when you may want to use Mercury Transmit for video preview instead.
When you are having problems with real-time playback with RAM preview, regardless of whether or not video preview is enabled the answer is always the same: reduce the resolution, frame rate, and/or color depth of the comp. The Resolution and Frame Rate/Skip controls in the Preview panel are intended for you to do exactly that, and the Shift+RAM Preview Options allow you to define two different sets of controls so you don't have to fiddle with those options frequently. Also, enabling color management will slow down RAM preview, as it does an on-the-fly transformation to correct the colors for screen display, similar to video preview. You can either choose View > Use Display Color Management to disable just the display correction, which will likely result in wrong color appearance of your comp, or disable color management in the Project Settings dialog altogether. Re-enable color management when you want to check the colors.
Otherwise, the best solution for slow playback in After Effects when you have a memory-intensive comp is a more powerful CPU and more RAM.

Ram previewing with multiple cameras

Hello
I'm a motion newbie...trying to ram preview a 10 second project with 2 cameras, a dolly cam and a sweep cam. The ram preview works for the dolly cam but when the timeline switches to the other camera it's obvious from the frame rate that that camera's view has not been processed into ram.
If I just Ram preview the sweep cam, which lasts for the remainder of the project it renders fine.
Thanks

I tried to replicate the problem but wasn't able to. DId you try a restart? Also, you might try copying all your project contents and pasting them into a new Motion project. If your project file is corrupt, this might help.

Issues with performance and RAM previews

Just did a major system upgrade from an iMac to a Mac Pro, and now I'm having an issue with performance...specifically with RAM previews.
When I try to do a RAM preview with audio, it grinds my entire OS to a hault (can't switch apps, or click on much of anything). It eventually clears up enough for me to stop the RAM preview.
So, I'm wondering if maybe my Memory & Multiprocessing settings might be off.
Here are my system specs:
Mac Pro
2 x 2.4GHz 6-Core Intel Xeon (12 cores)
64GB RAM
ATI Radeon HD 5870
AE CS6 (11.0.2.11)
AE is installed on an SSD drive and the scratch disk is an internal HDD.
Here are my AE Memory Settings:
Here's my GPU Info:
Let me know if any other info is needed...

You are reserving far too little RAM for other software.
See this: "Performance tip: Don't starve your software of RAM."
(Also, I recommend going through all of these materials: http://forums.adobe.com/thread/543440 )
Regarding the SSD: Putting your application files on it means that applications load/boot faster. This is fine, but that benefit is just when you first start the application. If you put your cache files on it, then you get the benefit every time that something is read from or written to the cache---i.e., many times per second, for the entire time that you're working. Put your cache files on your SSD. BTW, there's no reason to not put your application files and caches on the same SSD. The reason that you split things across multiple disks is to prevent simultaneous reads and writes to and from a slow disk; the program loading from disk happens at a different time than reading and writing cache files, so there is no potential for conflict and slowdown.

Audio Slow/Off-Tempo during RAM Preview & Rendered Video

Hi,
I am trying to do something very simple; cut a 5 second clip from a tv episode.
I opened After Effects, imported the episode, dragged that into the composition window to create a composition, clipped the beginning and ending points. Nothing fancy.
Whenever I do a RAM preview, the audio is super slow and way off. I can't even tell what they're saying.
I had read other places that if you ignored that and just rendered the video, it would turn out okay. That didn't happen. It's still messed up.
The episode video (avi) I started with has normal audio and I've double checked the frame rate options and audio options...
Can someone please help me with this, because I can't find an answer anywhere.
Thanks,

Extract/ convert the audio externally. If it doesn't even render correctly, it means it is compressed and AE can't properly deal with it.

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!
Ian

Hi Szalam and Martlomiej, thanks for the responce.
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.
Let me know if there are any other ideas.
Thanks for the help!

Audio distortion during RAM preview

I've been working for the past 4 months on the same computer, working on similar animations, nothing has changed much... then this happens.
**During RAM preview, my audio now sounds like an overloading robot.**
I can't seem to find similar issues on the internet to figure this out myself so I'm asking this forum. I haven't changed anything significant that could have altered my computer. I'm using:
late 2013 MacPro model
- with a SSD
- 32GB of DDR3 RAM
- 3.7 GHz Quad-Core Intel Xeon E5
- AMD FirePro D300 2048MB GPU
But I don't think it's the hardware
Old projects that I've worked on before are now doing the same thing. It's only during my RAM preview. Simple audio preview sounds perfectly fine. There is nothing wrong with the audio file because others that have worked before aren't working now.
Has anyone had the same problem?

I can't tell you what the problem was but I found the reset for all my preferences, tried it, and it worked. It solved my problem but I wish I could have found the source because I created my settings 2 months ago. I allocated more memory, changed a few settings but not within the past couple of days that would have created the problem. So i was just perplexed. I'd still like to know what the hell happened to cause this so I don't run into it again.
Thank you for reading this post

No audio on RAM preview - After Effects CS3

I can't seem to get AUDIO in RAM previews with my current project.
Scrubbing audio in the timeline works fine. But I hear no audio with RAM preview (from menu, from control panel OR hitting '0' on the ext. keyboard), and no playthrough audio preview ('.' on the ext keyboard). I can see the color bars moving in the audio window during these previews, but hear no sound. I've tried .aiff, .wav and .mov files - all of which work fine in other projects.
Here's the odd thing - if I open a previous project, audio preview works just fine in RAM and playthrough. I can preview my new audio files in the previous project, but not in a new project.
Haven't upgraded, or changed any settings or defaults since the last project a month ago. Audio buttons are ON in preview menus and panels.
Does anyone have an idea on what quirks or settings might be causing this?

Update - I have not solved the mystery: Audio files will preview in one project, but not in another. Project and composition settings appear to be identical. Audio is turned on in preview panel in both projects.
I have worked around it by importing the problem project into a separate project where audio preview is working as expected. NOW I can preview audio in the problem compositions....
But I'd still like to figure out the root cause of the problem. Your ideas would be much appreciated!

Why wont my audio play when I click on the ram preview option?

Whenever I try and play an audio file and clicked on the ram preview, the audio doesn't work and wont play. All of the audio settings are correctly set and when i go to the preview menu under Comp, the audio plays. How do I get the audio to play on the preview or ram preview??

YOu have not provided any exact system info or exact project, comp and footage details, so nobody can say anything. We don't even know your AE version.

Working with audio

Hi,
I've got a couple upcoming projects that will largely be focussed around music, and animating photography in AE in time to the music. I've checked the help guide, but can't seem to get preview with audio functioning properly. Is this even possible in AE?
At the moment, all I can do is preview sound "from this point onwards" using numpad "." but I need to see the video track simutaneously, in order to fine tune the animations. What's the best way to do this?
Thanks,
Danny

Yes it is possible, you can work with audio and you can play it back of course, use the RAM preview button.
But, AE is not the best program to work on Audio with. In fact most people I know and myself, avoid using Audio in AE at all costs. Now it's case of what you like, some don't mind audio in AE, but for most, the response times and additional features when working with multiple layers of audio just aren't good enough.

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.

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.
