Holding/lacking frames when Ram Preview. Mac OS X Yosemite

Do anyone know if Adobe is looking into fixing the problem with RAM preview your timeline in After Effects. That is lacking/holding/skipping frames the first 15-30 frames, and you have to run it once to the end, to see the beginning. It's really an issue for your work flow, and even more annoying when you have clients sitting next to you?
I checked with several other people too, just in case I might be my computer, but they have the same issue too.
Adobe wrote this" Adobe and Apple have worked closely together to test Adobe Creative Cloud applications for reliability, performance, and user experience when installed on Intel-based systems running Mac OS X Yosemite (version 10.10). " which seems like they might have missed this one?
If someone have a solution please let me know.
Best,
Kasper

It is an Apple bug. We have a fix to work around this bug in development, and we intend to release a version of After Effects with this fix this spring.

Clip going upside down when ram previewing on mac

i just got after effects on my mac and when i preview RAM my clip goes upside down please help

No one can be of much help because we don't know anything about your clip, what you did to the clip, how you set up your composition, what version of AE you are trying to use. I'm assuming you are new to AE and have never gone through the training materials and that you are using some kind of non standard video in your composition.

What do you do when Ram preview lags but info box still states "fps 24: realtime"

What do you do when you are trying to RAM Preview and you can clearly tell the sync with audio is inconsistent with other times that you have RAM previewed the footage. Basically sometimes in RAM Preview it lags and other times it doesn't, making it look like everything lines up but then next time you RAM Preview it won't line up. the funny part is the "info" box still will say "fps: realtime"
I am currently using a 15" MacBook Pro running on OS X 10.7.5 (Lion)
--Processor 2.4 GHz Intel Core i7

--AMD Radeon HD 6770M 1024 MB Graphics
I'm also using After Effects CC so I am going to try and upgrade to Mountain Lion or newer tonight.

Upgrading an operating system in the middle of a project is not usually a
good idea. Alternatively, it might fix issues. Remember that you will need
to repair permissions after the upgrade. Apple OS upgrades (especially
Mavericks for some reason) caused a lot of issues with software like After
Effects after users upgraded to it. See this:

After Effects CC crash when RAM preview

Hello,
I have project im working for 2 weeks. It was all good till yesterday. Today I opened and tried to Ram preview it, but either it crash and close or if I click the space bar to watch in the midle of ram preview it opens a warning window, with nothing inside (see attach) and I can not close it or do anything else.
Im running a Windows 8 in a IntelCore i7 4770 3.4GHz 3.4GHz, RAM installed 16GB - Video - NVIDIA GFORCE GTX 660
I just can not work this way, I need to finish this program and I can not find a good explanation for this crashes.
Thank you.

Hello Mylenium,
First I apologise for my poor english, see it is not my native language.
Now, I have tried that and it didn´t do me any good.
I have backups, however Im not sure if "save incrementally" means the same thing.
Plus, I have managed to RAM preview going by parts, however I don´t feel like that must be the only way to do it.
Thank you,
Eduardo

Error in After Effects RAM Preview after updating to Yosemite

There is an issue of RAM preview not showing video for the first several frames (a second or so) on the first run in After Effects.
No problem under Maverick.
Which means it has to do with the yosemite System-update.
This bug should really be fixed with some priority!
Apparently, Adobe cannot fix it (or don't want to).
So it's Apple who has to do something!!!

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

CTI jumps frames during RAM Preview

I find myself having to build a graphic opener with music for the first time in AE. Needing to time elements to the music, I've discovered something that probably has been happening since I've owned AE, but I've never paid attention to til now. When previewing, my CTI moves forward by jumping several frames at a time, instead of playing smoothly. This makes timing to the music beat all but impossible, at least for me. Is this a normal thing for AE?
Here is a sample of what I'm talking about...
http://www.creativeillusions.biz/AE_CTI/

Yes, OpenGL is enabled, as well as hardware acceleration. Here are my system specs...
Asus P6X58D Premium
Core i7 950
24GB RAM
nVidia Quadro 4000 - driver version 267.24
Windows 7 Premium 64bit
System Drive - WD Caviar Black 500GB SATA
2nd Drive(Pagefile, Previews) - WD Velociraptor 10K drive(600GB)
Media Drive - 1GB RAID5 (4 - WD Caviar Black 500GB drive)
Matrox MX02 Mini
CS5 Production Premium
I should mention that I have Nucleo Pro 3 running, but this happens as well with previews being handled by NP3, and with it disabled. The current driver from nVIDIA is 270.61. I guess I can try it out, but I don't like getting too far ahead of what Adobe has cleared.

After Effects Ram Preview Drops Frames , Using Strangely Too Much Ram

System Specs :
     CPU : Core i7 4770k
     Memory : 16 GB DDRIII
     Graphic Card : GTX 770 4GB RAM
     Storage : 256 GB SSD + 2 TB HDD
     OS : Windows 7 SP1
     Using After Effects CC 12.2.1.5
NOTE : NOT ANY ADDITIONAL HARDWARE IS ATTACHED TO MY PC . NO SOUND RELATED EQUIPMENT NOR CAPTURE CARD NOR ANY THING ELSE
Hi there
As you Already Don't know I'm an After effects Specialist Using it for quite long time . There is an Ancient Problem with CS6 CC versions . I have a short Small size 1080p Video , about 8 MB , I drag it into project panel and then put it into timeline hence it creates a sequence . There are no Effects and nothing added to timeline , just a small simple video . The Strange Problem is when I click "0" for ram preview , The video starts playing and the green bar above timeline starts to fill . When Ram preview Finishes and plays the video from beginning I See there are several frames Between which are not being loaded to Ram ! The video plays RGB color bar instead of main video and when I check the Green bar above Timeline I see that those frames are being dropped and there is no Green bar above them !
I have had this problem several times before but this time it is too important and the problem should be solved . What is obvious is that some frames are not being rendered or are being deleted after render !
Another Strange problem is that when I open Task manager , It shows AE uses around 10 GB ! of RAM when I press "0" for Ram previewing this video !
So there is a Logical explanation here , Somehow when I do ram preview this video it uses extra ordinary too much ram so AE is unable to load the full video (8 MB) into Ram and hence deletes some of frames .
most of my videos have not this problem and use acceptable amount of ram .I've had this issue with some of my videos till now .
Listen carefully : "This has nothing to do with AE preferences or low memory or plugins . because there is nothing wrong with any individual components of may hardware or software . I have far more than enough RAM for a 8MB video . My Memory has no hardware or software problem . I tested them and if there was any problem with memory or other hardware that should have affected other applications . I have the most recent AE version . I have the most Recent windows updates and drivers . I have a Clean virus free system , and as a computer engineer this strange AE problem is rarely caused by viruses , trust me . I have not any hardware instead of ones a normal PC has . I have not any problem with my whole entire system configuration because I have benchmarked my PC with several up to date softwares . I have tested my PC with almost any STRESS TESTING solutions available for really long period of time , 3 days by IDA64 . Not any driver conflict , dll missing , registry problem have been discovered , as I know perfectly how to solve them ."
I asked some of my friend whom are expert in AE . I handed them my videos and Watched ALL OF THEM HAD THE SAME ISSUE ! So the problem isn't related to my Local PC . What i believe is that there is some malfunctioning or miss coded part in AE source code that decides to reserve such a huge strange amount of ram for such a tiny 8MB video . The point is that the AE works fine , no crash or any problem report . So the AE it Self decides to allocate such huge amount of ram and thinks it is correct ! So I think this is a work around that AE developers in adobe are using to bypass a problem or conflict ! by Using more amount of RAM . I think that there might be some miss understanding between the AE and my installed codec . I installed MEGA CODEC PACK on my PC to enable some new codec supports , and so are some of Windows default de/encoders changed to new ones . I think there shouldn't be any problem But there is something wrong between AE and de/encoder modules !
Please any one with any suggestion , I really appreciate your advices .

###UPDATED###
Well thank you guys for your patience ...

I think you hit the point ! Thats K-lite codec pack installed on every machine which the video is tested on ! The point is whats wrong with it ?! I have had never ever any problem with this codec pack !!!
The deadly question : So what are the alternative ways to work with codecs that AE doesn't support ?! because installing codec looks simple and sufficient !

Ram Preview - Stopping after 40 frames

Hi All,
I've recently moved to After effects CC on my home computer, and for some reason whenever I try and RAM preview it stops after 40 frames or so...
The animation is REALLY basic (full screen shape layers turning on and off to the music) and an mp3 file playing in the background.
My computer spec is:
21.5-inch iMac Mid 2011
OSX 10.8.5
2.8 Ghz Intel Core i7
16 GB 1333 MHz DDR3
AMD Radeon HD 6770M 512 MB
I have the following multiprocessing prefs:
I would greatly appreciate any help on the matter... the project seems far too basic for it to be having genuine issues with playback...
Dan

Hi Rick,
Thanks for the reply.
I've changed the .mp3 file to a .wav file and that seemed to fix everything, for the time being...
It previewed for 10 seconds fine, but after about 15mins of working on this the RAM preview area has started to shrink again and it's only previewing just over half (5 seconds).
I changed my memory and allocated 4GB to other apps, also turning off rendering multiple frames... (by the way for some reason I can't get my 'actual cpu's that will be used' to change from 0? This seemed odd). Still no change.
I've attached a screenshot of my comp details below, along with a shot of my screen when RAM previewing... (you can see the green bar does not go all the way). I'm not working with ANY footage which is why this is most peculiar, just the wav file so I can edit to the beat.
Once again if there is anything else you can think of...

Frame counters during RAM preview and playback

It is my understanding that I should be able to view the number
of the currently processing frame during the course of a RAM preview
in both the timeline counter (in frame display mode) and in the info panel.
This is not working for me, and I would like to see if I am missing something.
Here is the status of the counters with a RAM preview in progress.
The only updating frame counter is at the bottom of the composition window,
and it would not be visible while processing a full-screen RAM preview.
RAM PREVIEW IN PROGRESS
This is the status of the counters during playback of the RAM preview.
The playback CTI is at about frame 90 of 912, but the counters in both the
composition window and timeline are frozen at zero, while the info panel
is frozen at the last frame number of the timeline (the last frame rendered).
RAM PLAYBACK IN PROGRESS
During spacebar playback, only the composition window counter displays
the current frame. The timeline counter is frozen at the frame number where
the CTI was parked when playback began (in this case, from frame 0).
The info panel only displays the framerate of the playback.
STANDARD PREVIEW PLAYBACK
If I stop either a RAM or Standard preview playback using the spacebar
the timeline counter will update to the CTI frame, but if playback resumes
the counter stays frozen where the CTI was parked when resuming playback.
I am experiencing this behavior using frames, timecode, ft+frames, and using
"From Current Time" RAM previews.
Please tell me I'm doing something wrong.

The question I posed was:
2. Is there a way to display the number of the frame that is currently
being processed during the course of a RAM preview?
The answer was:
>Info panel + timeline display set to frames.
Your tip to disable "Show Rendering Progress In Info Panel And Flowchart"
is very helpful. By unchecking the option, I do get a count of the currently
rendering frame during RAM preview... thanks for that!
It does seem a bit counter-intuitive to de-select this option in order to
view what might be the most the pertinent information (the current frame)
instead of "whizzing minutiae", but it does confirm I was missing something.
As for Mylenium's answer "timeline display set to frames", I can't seem
to get a running count in the timeline display under any rendering
or playback circumstance. I am a long-time Premiere user, and I was
expecting the timeline counter in AE to behave in a similar manner by
updating the current time during playback.
Is it the proper function for the timeline display to only update when parked?
If yes, I can get used to it. Again, I just want to know if I am missing something.
thanks

Vertex Array Object deleted after full screen RAM preview

Hi,
I'm writing a plugin where I use OpenGL VAOs. Everything works fine, also RAM preview, but when I cancel full screen RAM preview and render a new frame the VAO is somehow deleted. I called glGenVertexArrays for testing and the handle it returns is 1, which was previously the handle of my valid VAO.
Has anyone had this problem? It only happens when using full screen RAM preview. I also tested this in the GLator sample by generating dummy VAOs and it's exactly the same.

Hi Rick,
Thanks for the reply.
I've changed the .mp3 file to a .wav file and that seemed to fix everything, for the time being...
It previewed for 10 seconds fine, but after about 15mins of working on this the RAM preview area has started to shrink again and it's only previewing just over half (5 seconds).

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

AE CS5 (10.0.1.19) Ram Preview - Audio stops and continue playing randomly

I already reported this issue to Adobe as a BUG but I want to ask here if somebody else have this problem or can confirm it.
Audio breaks/stops and continue playing randomly when 'Ram Previewing'
It happens mostly when the RAM is fully filled up with image cache files! When the Ram is not filled up totally with image cache files it happens rarely!
Steps to reproduce BUG / issue:
1. create a new composition with a length of for example 5 minutes.
2. create a new solid with size of 50x50 pixel and animate the position of the solid for a very long time so when ram previewing the whole ram/memory gets filled up with different image cache data (this is very important!). Alternatively you could use a long video file to fill up the RAM completely.
3. import a wave file .wav 16bit 48khz uncompressed which is very long for example 5 minutes.
4. insert the wave file in the earlier created composition which contain the animated solid or video file.
5. Set the work area bar (preview range) for the whole composition.
'Ram Preview' the composition until the whole RAM/memory is filled up with image data.
AE has to stop rendering because there is no more space available in RAM.
make sure 'from current time' checkbox is off.
6. listen to the audio which stops playing randomly for about 1-2 seconds and comes back and continues playing (***BUG***)
7. Now set the right handle of the composition work area bar (preview range) to less then the maximum RAM size
(less then the green cache indicator on the right side)
8. "Purge image caches" or "Purge All"
9. Ram preview the now smaller work area
10. listen to the audio. The audio breaks are gone! (***Workaround***)
Additional information:
I have the latest After Effects CS5 update installed (10.0.1.19)
This behavior is tested with different audio drivers inside After Effects CS5 (After Effects WDM Sound, Generic Low Latency ASIO Driver, ASIO DirectX Full Duplex Driver)
I also tried different Sample Sizes Buffers (alternatively to the default 2048 samples) but without success.
Reducing the amount of RAM which After Effects can access didn't solve the problem!
System:
Win7 64bit all latest Updates, 8GB RAM, CPU: intel Core 2 Extreme QX9300, nVidia Quadro FX 2700M, IDT High Definition Audio Driver v6.10.0.6227
There is no driver problem on my system because After Effects CS3 & CS4, Premiere & Soundbooth CS3 CS4 CS5 have no audio problems!
I have lots of other professional audio software like Steinberg Cubase 5.... on the same system and they all work fine.
I also turned off AVG Anitivirus and Windows firewall for testing without success.
AdobeQT32Server.exe, dynamiclinkmanager.exe, PProHeadless.exe, afterfx.exe do not get blocked by firewall they have full permission.
The CS5 Production Premium installation went fine and without errors and antivirus protection was turned off for the installation.
Any help would be nice!
Felix

Yep, I agree with craulmedia....
It's 1 month ago after my initial post and no valuable feedback from Adobe although I filled out the bug report in addition to this post and provide my email for further information.
The only reason for upgrading from CS4 -> CS5 production suite was the use of all my 8GB RAM in AE and now AE can use it but when it's using it the audio have issues.
CS5 is on the market for nearly a year and still have such essential issues... And my fear rises there will be no valuable update fixing these issues but instead Adobe forces me to upgrade later this year to CS6 in hope something change...
I have had support request for different Adobe products in the past including telephone support, web support via Adobe ID... none with success the web support answered my request 3 weeks later with the message they will look into it... time went by and in the end the result was "Yes we know it's a known bug" the bug did not get fixed for that CS version. it even exists in the next major CS release! (talking about EncoreDVD here). Once the web support answered weeks later when I was in holidays and after some days I was not able to respond they closed my case. I reopened the case but never got an answer! Telephone support is nearly waste of time because in 95% of all cases it does not help to reinstall the whole operating system and talking to people who know less about computers in general or Adobe products then my mom - it's a waste of time.
I don't want to blame here anybody for things happend in the past I just want to point out that this time I choose an other support channel (bug report and forum post) but it seems that this support channel is also a waste of time after 1 month with no valueable feedback!
I bumped up this post 2 times and thanks to craulmedia for the third time.
And now here is my fourth time *BUMP*
All I got so far is: "I saw your bug report it's in the queue"
Is it still in the queue? which queue nr. does it have? how long will it take to get any answer? is it reproducible? Is it confirmed as a known bug by Adobe? Is Adobe working on a fix? When will this fix be available? Is the fix provided in form of an update or in the next major release?
OK, I know this is a user to user forum and Adobe people only stop by in their free time and there is no guarantee for any real support.
But it started out so good in the first time...
Last 2 things I want to add here:
1. Why should I provide my email in the bug report? Sure so Adobe can get back to me for further information... but wouldn't it be nice if Adobe would be so kind to give some status report to that given email as a small present for the enthusiastic beta testers ?
2. please Adobe take a look at www.uservoice.com already Autodesk started to move there with 3ds Max.

RAM preview green bar vanished

Hi, does anyone know why the green bar that displays cached frames for RAM preview wouldn't display?
Yesterday it was working. Today it isn't.
I've naturally tried restarting my pc but it's still doing it. I've not altered any settings either in After Effects or on my pc. I literally came in to work this morning and it's gone.
Anyone any ideas? Is there somewhere where I turn it on?
I'm using AE 7.0.1
Windows XP sp3
Intel Xeon 5110 @ 1.6ghz
2gb Ram
Thanks

I don't see the green bar filling up at all.
I've opened up some old AE files to see if it's just the new files it's affecting, but it's affecting all my AE files.
I click the RAM preview button, I see the frames numbers being rendered in the Info panel, and I see the animation rendered in the composition panel.
But no green bar on the timeline filling up to tell me it's progress.
Also scrubbing the timeline would make the green appear, but now it doesn't. It's just totally vanished and not working.
My settings are exactly the same as the identical machine next to me yet that is working just fine.

Mac 2008 with yosemite reboots

why when exiting sleep mac 2008 with yosemite reboots?

I fully understand, BDA, and I would expect it of you, being the helpful man that you are.
I just think that the less extraneous clutter in a forum, the less likely there will be posts by other stray posters in the forums.
The thing with Yosemite is that the beast is loaded with bugs and idiosyncrasies that Apple has not been able to fix yet. As we both know, Apple usually doesn't get a major new release even halfway right until the dot five update, and Yosemite is barely at 10.10.2, a very long way before 10.10.5 or 10.10.6.
Many pros at the Adobe Photoshop forums have been forced to downgrade to Mavericks as the only way to cope for now.
