RAM Previews No Longer Real Time

Work computer.   Mid 2010 Mac Pro with 64GB of RAM. Running After Effects version 11.0.4.2.   Multiprocessing off.   AJA Control Panel v3.
1920 x 1080 comps, 29.97 fps, no 3D.
The Mac was running Mountain Lion and RAM previews were FINE. Zero issues.             Ever.
The computer was upgraded to Mavericks 10.9.5.      I use the term upgrade loosely, BTW.       Now ... RAM previews no longer play in real time. Most I get - and it fluctuates - is 19, 20, 23 frames per second, never 29.97.    Sometimes it blasts all the way up to 40, 45, 47 like it’s playing catch-up, but that’s rare.
- Restarted the computer. No change.
- All projects.   Makes no difference, old legacy projects or new.
- Even simple 1-layer projects with simple position animation, no effects - not real time.
- 8 bit mode, not just 16 or 32 bit.
- Color management both on and off.
- Simulate output on and off.
- Preferences -> Video Preview was set to AJA, so I tried Computer Monitor Only. That doesn’t work either.
- Full Rez, Half, Quarter. . .. . doesn’t matter.    Never real-time.
I've seen others ask about this issue but none of the posts ever resulted in "you need to set 'this' to 'that'" etc.        Have any suggestions?
Thank you,
Marc

Mavericks and Yosemite have both have quite a number of issues when folks upgrade to them.
Apple is really starting to bother me lately. First the attitude evident in the Final Cut debacle, then the Mac Pro annoyance, and now the OS upgrade issues... I know smartphones are making them boatloads of money, but they really seem to be neglecting their professional users who've been with them for years before iPhones were even a thing!

After Effects will RAM Preview not in real time

Hi, we have 3 adobe After Effects CC up to date here, we are working on a 60fps project in HD 1080. Nothing crazy.
We have 20 Gigas of ram. Mac OS 10.8.5 octo core 2011. ATI Radeon HD 5870 1024 Mo. SSD disque crucial m500 256 gigas.
We have a lot of problem with Ram Preview. (on every project)
Everything works fine until, we don't know why, the ram preview is getting not realtime, like 30fps or under.
Sometimes purge memory do the trick but not always.
We need to reboot and it works again, but few minutes.
We made a test on CS5 and it works well realtime, but same problem on CS6.
I tried to delete all the preferences to check but no difference.
We are working with nfs network account but i always redirect disk cache to local disk (set to 20 gigas) and also media conformed cache (database and cache)
We are getting mad, it's really hard to work that way, rebooting each time.
Maybe an issue with Global performance cache introduced in CS6 ?
It's not a footage/project issue because the entire project (a blend of tiff, png, prores422) can be played 120 frames/sec without any problem on after CS5, after CS6 (when it works), CC (when it works).
The problem is when working on project, changing layers, adding effects, After CC starts not be slow and not realtime using Ram Preview.
Also, when we are previewing, a lot of ram is not used, it only uses like 20% of the ram.
We hope for a nice patch very soon ....

60 fps is a very high frame rate not usually supported. If your footage is shot at 60i then it is probably 29.97 fps when converted to progressive video. If the footage is actually 60 fps then you will be better off, and by better off I mean more folks and streaming services will be able to view your video at the proper speed.
So my recommendation is to first determine your audience and then set up your comp appropriately. In all my years in the business I have only delivered one high frame rate project and that was 48 fps.
The other thing I would recommend is to optimize your system for AE. That does not necessarily mean throw all your available ram and processors at the app. There are some good recommendations here: Optimizing After Effects Performance

After effects cs6 ram preview saying NOT REAL TIME

Every time I try to ram preview something in AE CS6 at 59.94 fps it always previews it at only 11 fps and it says Note: zoom is not 33.3% I have my Composition settings to 59.94 fps and the quality to quarter but nothing helps? Im using 6GB of Ram and have 2 of my 4 CPU's used for it.. is there something I'm missing?

Without proper system info, comp settings, details about your footage etc. nobody can say anything. you are merely throwing us random fragments of info but leaving out the important parts.

Configuring FCP to preview project in real-time on TV via Camcorder

Hey,
Somebody that I've worked with explained to me that it was possible to hook up my camcorder (GL2) by firewire to my iMac and also connect the camcorder with RCA cables to a regular TV so that the camcorder bridges the image of my project to my television so I can preview my project on a TV in real time.
He explained to me that I only had to hook up the camcorder and configure Final Cut Pro HD in the "Audio/Video settings" so that the video feed is streamed to the television.
Obviously, it doesn't work for me since I'm posting here, so I was wondering if somebody knew the settings I had to put in "Audio/Video Settings" to insure that I can see the video that I'm working on in real-time.
Thanks for your time!!
20" iMac G5 2GhZ 1gig RAM Mac OS X (10.4)

its a simple thing once you do it the first time:
assuming you have connected it all up,
go to FCP's View menu and choose "Refresh A/V Devices" (Opt-F12)
then View > Video Playback > Apple Firewire NTSC
then View > Audio Playback > "Audio Follows Video" (or Firewire DV)
then View > External Video > All Frames (Cmd-F12)

How to preview audio in real time in the canvas/timeline

Hello there, I am new to Apple and FCP (though am an experienced Avid editor) and I have managed to get acquainted on many things already but the following is driving me nuts:
Whenever I try to play most audio clips (sfx or music in mp3/m4a/caf format) in the timeline I get a beeping warning sound as if it was unrendered. This happens even when only playing 2 tracks of audio and nothing else. the same clip plays absolutely fine in the viewer but not in the timeline/canvas. The only clip I have tried that I don't have this issue with is the sample audio clip downloadable from the FCP help menu.
I have made some research and believe this is due to sample rate of the source material which is not compatible with that of the sequence. In this forum someone has advised to convert all audio files to 48Khz/16bit sample rate to make things easier. Does anyone know how I can do this and/or offer general advice on this issue?
Many thanks, Emi Polito.

The list of audio files that FCP can work with is in the manual.... MP3, m4a's etc aren't supported. You need to transfer them to Aif's or WAV files. MP3 and M4a files are delivery formats, not editing formats. Transfering them in QuickTime or iTunes or even FCP or compressor all work to do this. But it has to be done in order for FCP to work with them.

RAM Preview in real time with Matrox Mini

I followed this thread with interest. I upgraded from Production Premium CS5 to CS6 last month. I haven't been able to get Realtime RAM playback since. I'm also monitoring using a Matrox mini and am wondering if this is factoring into the problem. I recently replaced my mini because I was losing communication with the box. I did notice, with the box out of the equation, that RAM playback was in realtime. My test comp runs 5 seconds at 29.97 fps, just a photo moving from point a to b to c, with blur, over black. When I try RAM playback, the message I see is: fps 11.xxx (xxx because the frames vary slightly throughout playback)/29.97. Note: Zoom in not 100%. Interesting thing is that when I delete the photo layer and just keep the black, RAM playback seems fine.
I did adjust my RAM allocation a little, to no effect. Here are my specs:

If you disable video preview in After Effects to the Matrox device, does RAM preview run in real time?
In After Effects CS6: Preferences > Video Preview, set Output Device to Computer Monitor Only. Matrox devices may also require you to disable WYSIWYG preview in their control panel.
When video preview is enabled, every frame is transcoded on the fly at display time to the format (dimensions, PAR, frame rate) requested by the device. This requires some memory and processor power and has an impact on performance. If having video preview enabled is in fact contributing to the issue, you can reduce the memory requirements of the frame (and therefore the processing power required) by reducing the RAM preview frame rate or resolution values in the Preview panel, reduce the project color depth, or disable color management in the Project Settings.
Worth noting here that After Effects CC 2014 (13.0) uses Mercury Transmit for video preview, instead of the older QuickTime and DirectShow technologies, and while it is still subject to the limitations above it provides better performance.

Jerky and "Not In Real Time"

Why is my footage in AF 5.5 jerky and why do I get a message in red saying"Not in Real Time"?
Any ideas please?

You're not giving us any information to work with to help you. We need to know a lot more to help you. Please provide answers to the questions listed here: "FAQ: What information should I provide when asking a question on this forum?"
I'm going to take a guess, and I'm guessing that you are previewing by pressing the space bar. Don't do that. Use RAM preview to get real-time playback of previews.

Audio preview no longer works correctly since AE-CC update

Hi everyone.
Since updating AE CC a couple of days ago (now on 12.1.0.168) on OSX 10.8.5, 2.7GHz i7 16GB RAM, the audio and RAM preview no longer functions correctly.
The steps I follow are:
Open AE
Open project
Press . to preview audio from where I am on the timeline, OR RAM preview workspace
What happens is my cursor turns into the wheel of doom for a about 20 seconds, then the playback begins but the audio is sped up which is wrong. Video is correct speed.
If I stop the audio or RAM preview, then preview again, everything is fine and plays instantly. If a RAM preview loops, then the audio reverts to normal speed.
I can open up any and all of my different project files and audio previews perfectly and instantly as it should. It's just the first time I press the . key on a freshly opened instance of AE that I get this problem.
I've tried restarting my mac to no avail, and also changing the pref settings away from what the settings have always been and that doesn't work either. I've even trashed my prefs and that also doesn't work.
I work exclusively at 25fps. Frame rate for RAM preview is set to auto (25) and changing this from auto to 25 doesn't work.
Memory settings are default since trashing my prefs, 16GB installed, 4GB for other apps, no checked boxes are ticked.
Any ideas on what has happened please?

Thanks for letting us know, however, this is a user to user forum and not an "Apple Run" forum.

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.

Specifying start/end of "Save RAM Preview"?

I save RAM previews to preview comps with real-time audio, since AE's RAM Preview lags on audio, preventing me from syncing video and audio. When I save the RAM preview, it starts slightly after where I have it set in AE and ends much earlier. How do I specify the RAM preview start/end parameters?

You can specify beginning and end of the duration to be previewed by setting a work area.
That doesn't necessarily seem relevant to your problem of lagging audio.
If audio and video are out of synch, then please file a bug with details about version numbers of software, kinds of footage, et cetera. You can send bug reports to aebugs <at> adobe <dot> com.

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...

AE CS6: How to Ram preview or playback in smooth real-time everytime?

Hi guys,
I would like to know how to Ram preview or playback in smooth real-time everytime? I'm using a videohive template and adding in my footages to the media holder comps. The AE template is complex I guess.
Hee's the problem, everytime I make a change to text, add a footage replacement or make any change at all, I have to completely render and wait a long time to see my final product in "Real-time"/smooth. Is there someway that I can render out the whole thing once and even though I make a change the entire video will play smoothly without rendering time?
PC Specs:
HP 510t
Windows 8 Pro x64 bit
16GB Ram
i7 2600 CPU @3.4 GHz
GTX 660Ti

Proxies don't affect rendering beyond the point of reducing the resolution and thus the nuimer of pixels that need to be processed, but since the retain the effect properties at full resolution, e.g. a large blur still renders just as slow. They are more a means of reducing file I/O bandwidth while working really.... As I said, the best way to optimize this would probably be to restructure the project so parts that don't change reside in separate pre-compositions and can use the disk cache.

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?

After Effects will not RAM Preview in real time

Recently I have started working on a new project and can't work on it because my RAM Previews are not in real time anymore. I have only had this problem since I started this project a few days ago. Every other project I have done I've never had this problem before.
I have 10 GB of ram allocated to After Effects, my clips are in 59.94 fps which I have set the composition to as well. When I ram preview it tells me 50.019/59.94 I know what this mean, I understand it's telling me to change my composition's frame rate to 50 frames, however if I do this then music plays too slow. Right now my problem is that the clips aren't playing fast enough for me to see if my editing and time syncing is acurate. When I render the video everything is synced up fine but this is making my editing very inconvenient and I would like a fix please. I tried: Clearing my disk and media cache, unchecking "render multiple frames at once", taking off all effects on the clips, using different clips, AND even reinstalling After Effects CS6 but nothing has worked. I really badly need a fix to this problem. Any help would be greatly appreciated thanks!!

> The clips are in 59.94 frames, so the composition is in 59.94 frames. If when I upload to the internet it goes down in frame rate so be it.
You are misunderstanding the typical video workflow.
Composition setting are supposed to match the characteristics of the intended output, not necessarily the characteristics of the imported footage. This is how you ensure that what you preview exactly matches what you output and what your viewers will see. Consider, also, that most compositions use assets with many different frame rates, sizes, etc.
> I do have a large monitor but I've been using this monitor since December and haven't had a problem with it until now.
Great. But you're having a problem now. And it's because of a bottleneck somewhere between your RAM and drawing the pixels to the screen. One more reason that this might be happening is that you're running a GPU-heavy application; note that web browsers can also be GPU hogs these days.

Black magic and Adobe After effect cs6 Ram Preview not real time

Hello,
I'm on a MAC PRO with the OS 10.6.8 and 8Go Ram, the problem is when i turn on my preview video on the Blackmagic the video monitor is not in real time and the after effect is so slow. When i put it off (computer monitor only) it's ok but i havn't my video monitor of course....and i need it. Is there some tricks for having my black magic (1080 i 50) ON and a RAM Preview in real time ??? ! My drivers Black magic is the 9.5.3 it's the highest driver for MAC OS 10.6.8 + ADOBE CS6+ FCP7. Thanks for the read. ( i tried update adobe, change qt library, change aspect ratio, pixel, preview ram settings, change drivers black magic and other but nothing work )

What is the color bit depth of your project? (8, 16 or 32?) Have you changed that recently, or have you changed the frame rate or frame size of your comp?
Performance with video preview to an external monitor is almost always related to the pure bandwidth requirements of the frames you're sending to it. If the frames require more memory, it may be slower. Frame size, frame rate, and color bit depth all affect the memory requirements of the frames.
If none of those parameters has changed, troubleshoot the general performance of your machine. If there are other processes (look in Activity Monitor) that are using significant processor and/or memory resources, they may be causing a bottleneck for the frames getting out.
