After Effects cs 5.5 Playback jumpy

I'm trying to do a simple effect using After Effects 5.5 it is a "pan" of a slogan on the bottom of a photoshop graphic. When rendered out, or even after ram previewing it, it seems to studder, or jump, it just isn't smooth.
I've exported it as and avi, tiff sequence, etc, but it just doesn't play right. I even brought it into premier, which I thought was the problem but have traced it back to AE.
It's not just this, I've opened other projects and nothing is playing back smoothly.
thanks for any help.

The first problem I see is that there's no motion blur applied. The second problem is that it doesn't follow the six second rule.
Try this. I'm assuming that you rendered to something other than a swf or flv. Import a rendered clip and change the frame rate to a higher one. If your clip is 24 or 25 change it to 30. If the frame rate is 30 change it to 36 or even 50. Now drag the clip to the new comp icon in the bottom of the Project panel and render this clip using Jpg compression. Playback the file. I'll bet that it will be smoother. It's impossible for me to test the clip because you provided a flash file. If you could post a quicktime rendered from the project I can probably get you a file that will playback smoothly.
If there's really some jumps in the render you'll see them if you step through your render one frame at a time.

After effects ram preview video playback issue

Greetings -- I have Mac Pro 2.93 GHz 12 Core with Nvidia Quadro 4000 & 24GB Ram.
During ram preview playback, it seems as though the video isn't refreshing fast enough in the display -- meaning its almost as if I can see the refresh on the top/bottom half of the frame happening separately. It's a bit diffucut to describe, actually. This does not happen with the same clip in Premiere, just AE.
The rendered video is fine and plays in QT/VLC, etc. without issue, it's just ram preview and is very distracting.
Any help woul dbe greatly appreciated!

CS6, 720p clip, 100%, Full, 29.97 fps. This may be related to the preview settings... It seems to go away if I turn it to final quality v.s. adaptive.

Slow preview playback in After Effects

Hi Folks
I just recently set up CS6 on a new z820 workstation and for some reason my after effects timeline does not playback in realtime when previewing. Everything is green on the timeline, yet when it plays it is about half speed. I have no doubt my system has the specs to play rendered media in real time (2x8core, Quadro 4000, 64GB Ram, Sonnet hard drive array) so obviously I have something set up wrong. I'm running a Kona 3 with the latest drivers and I suspect this is the culprit. I've had other issues related to the Kona, such as losing display to my external monitors sporadically. It will be fine for a while then suddenly the output signal turns either solid green or some form of garbled junk. Very strange, although the Kona output seems perfectly fine when I'm in Premiere.
Anyhow, any help zeroing in on the problem would be greatly appreaciated.
Best,
EE

Thanks Tom
However, I do think I have playback set to computer monitor (not in front of system right now). Definitely seems like there's something AE doesn't like about my card (it is an older version of the Kona 3). I have a support ticket in with AJA so hopefully that will turn up something.
As far as my Quadro 4000 goes, I was kind of forced into using it on account of other software on my system. If it was up to me, I would have put in a GTX680 or 690. I have a GTX680 at home and it is rock solid in AE and Premiere. Timelines that are heavily dependant on GPU accelerated FX render about twice as fast on my 6-core/GTX680 vs my z820/Quadro 4000 work system. I'm hoping to upgrade to the Quadro 5000K when it comes out, possibly with the Tesla sidekick. In the meantime, I have to sort out this Kona thing

HELP! My After Effects project is complete, but when I render out and playback the video is a lot faster then the original playback.

I have finished my After Effects project. The project includes a lot of text and fade ins and outs and looks perfect in the playback. But once I render and playback with Quicktime the video does not look the same. The animations are very jumpy. Please help!
Thanks,
David V

Hey David,
Also, my AE comp is 29.97, but i have four other comps in that one and they're 23.97 fps.
It seems like that would be the likely culprit. Is there a specific reason those comps (which are, I assume, nested inside the 29.97 one?) are 23.976? Do they contain 23.976fps footage? Mixing of comps, video and different frame rates can often cause juddery playback after rendering, as the interpolation of the frame rates to the master render frame rate happens without any interaction on the user's part. But AE gives many different options (and techniques, everyone has their own) to assist with getting the frame rates and speeds more aligned so the final frame rate is perfect for them all. It takes a little planning, that's all.
Let me know, I'll be glad to help if this is the issue.

Jumpy AVCHD rendering in After Effects CS4

Hey Everyone,
i am working with ACVHD footage which can easily be edited in ae and premiere cs4 on my computer. But since
have rendered out my material (I have tried, mov, avi, flv, and whatnot) it runs fluently but is now and again
jumpy when played. Its like a few frames are repeated sometimes.
What is the trick to achieve a good result, what is the best output format? Can anyone please help?
Thank you in advanced!
Best,
Alex

Hi there,
( Wow! An actual Adobe employee in this forum... ;-) )
I am experiencing what I would think to be AVCHD decoding problems in Premiere Pro CS4 as well and am wondering, if this might be the same problem as in After Effects.
I have observed the following effects:
- Sometimes during editing in Premiere a single frame will simply be the wrong one. This error is then persistent and can be reproduced until some internal buffers get rerendered and the problem may vanish, for instance, after I render an effect or dissolve in a different part of the timeline... until it happens again at a totally different location.
- When I render the video out (export in Adobe Media Encoder or playback to my "old" Sony HDV cam via firewire) in different formats (I prefer Blu-Ray MPEG2 because it is faster for Full HD material than a AVCHD render), the problem appears in the resulting video as well about every few minutes or so (Frames jump back and forth or sometimes a single wrong frame is displayed). The problem shows up at random locations and no two renderings have the same problems at the same locations.
During editing I was ok with that behaviour and could even live with the non-realtime previews. Hey, I am a programmer myself and know, that bug-free software is not possible to make.
But I was expecting, that at least the final rendered video sequence would be ok. Well, this is obviously not the case and renders (pun intended) the whole result of the video project unusable.
I concur, that there seems to be a problem in the AVCHD decoder used to get the frames that need to be rendered (I assume that this is somehow a part of the ImportProcessServer, which uses gigs of memory on a project with something like 1400 video clips. I do not think, though, that this points to a problem in the AVCHD data stream or is even connected to Panasonic cameras. I am shooting with a Sony HDR XR-520.
My System:
Core i7 950 QuadCore @ 3.2 GHz
NVidia Geforce GTX 275
Windows 7 64bit (performance index 5,9 due to hard disk, everything else 7,3 - 7,5)
12 GB RAM
4 TB Hard Disk space
Adobe CS4 Master Collection
I have been a fan of Adobe software for years and am also using After Effects.
Under these circumstances, I will have to rethink upgrading to CS5, though. Based on previous support and update experiences I do not dare hope to see a fix for this severe bug in an upcoming CS4 patch!?
Regards,
Gunnar

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.

After Effects pausing for a second before playback

Once a prerender has completed after effects takes a second to start the visual playback. VO starts straight away. This corrects itself once the timeline has completely played through and starts from the start.
Any ideas?

As Rick says, this is a known bug with Mac OSX v10.10 (Yosemite).

After Effects 13.1.3 Is Constantly Giving The Error: "Needs 2 or more frames for playback"

I have After Effects 13.1.3 and I'm using a 2011 mac pro 17" with 16GB of ram, but I have any project I have I'm not able to work on due to After Effects not being able to render more then one frame at a time. When I go to RAM Preview it says "After Effects Error: RAM Preview needs 2 or more frames to playback." This phenomenon used to happen whenever I had Adobe Premiere open at the same time, but Thats not the case anymore. It just happens all the time. I can open a project, but after a little less then 3 minutes it reverts back to only rendering one frame. Purging the memory does absolutely nothing, in fact purging anything makes the problem come up immediately.
This is frustrating! I have deadlines to meet. Not to mention having to pay out of pocket for software that hasn't worked well since Mac OS X 10.8. I shouldn't have to pay for defective software.

That sounds really frustrating! I wish I could help, but it may be beyond my technical know-how. It's not a very common problem, obviously, or AE wouldn't be enjoying the market share they currently do...
Since most people with Mac Pros aren't having problems like this, we need to figure out what's different about your system. Also, the fact that this is a persistent issue across versions is an interesting flag.
Could we have full system specs.
A screenshot of your memory and multiprocessing settings wouldn't hurt.
Any chance you've got an issue with the computer itself? A RAM stick could be going screwy or something. AE uses a system in ways that NLE's and other software don't, so it's possible that it's bumping up against a hardware issue that you wouldn't notice otherwise.

After Effects CC sluggish "Fast Preview" playback

Hello,
I've recently upgraded from After Effects 5.5 to CC. I've found CC to be very sluggish in many ways, from using the interface itself, to scrolling down my layers using the mouse wheel, to not being able to get realtime playback once I spacebar preview a bit of my timeline.
None of these things were or are issues with After Effects 5.5 which I still have installed thankfully.
My main question is about space bar previewing (foreground memory) bits of your timeline in CC. (Not ram preview)
In After Effects 5.5, it didn't matter how complex my project was, if I hit spacebar to preview it would slowly preview and load, you could see the green render line building, as soon as I was happy I could scrub the rendered green area and if I hit spacebar at any point in the rendered area, After Effects would playback realtime.
This is very important to me because when dealing with little intricate key framing it's nice to be able to playback a given spot within the rendered green area and get realtime playback instantly.
This is impossible to do in CC, it doesn't matter if I spacebar preview or RAM preview an area. When I scrub the green rendered area and hit spacebar to get realtime playback it will never manage to playback at full framerate. The only way to do this is to RAM preview but that defeats the purpose because you have to keep adjusting the work area bar, and it's just not the same as spacebar previewing which gives you more freedom and you don't have to wait for the RAM preview to kick in.
Is their any work around for this? and is their any plans to fixing the general sluggishness of After Effects CC?
Any feedback would be greatly appreciated.
Many Thanks,
Jakub

Hey Szalam,
I'm on Mountain Lion, the sluggish interaction occurs with or without multiprocessing enabled, my cache is set to 100GB, my composition's are always set to standard classic renderer. Again I also have CS5.5 installed simultaneously and it runs lightning fast in comparison just with default settings. But to be clear, this is not a complaint about actual rendering to file but of not having realtime spacebar preview and the general sluggishness of the UI interaction.
The benefit of realtime spacebar preview is you can preview yourself a little section of timeline and work within that area in almost realtime. If you make a small keyframe adjustment then the green preview line only breaks in that tiny section and it only takes half a second to spacebar render it again, then once you hit stop, the scrub line stay exactly at that frame.
Not having it playback in realtime really does slowdown the process and as Coolbaboon said, it forces you to work in a less intuitive manner.
Again if theirs any current workaround I'm all ears. In the meantime I hope this will be fixed as part of the big overhaul hopefully coming soon. Realtime spacebar preview and a way more responsive UI, like 5.5 had.

Playback has frozen in Premiere Pro CS6, it started when I added some after effects compositions to

Playback has frozen in Premiere Pro CS6. I am running a 1080p timeline and it appeared to start when I added some after effects renders to my timeline. The playback head still runs through the timeline and audio plays normally but the video completely stops and cannot be viewed in real time.
I have plenty of memory and a very good graphics card running 64Bit Windows 7.

Mercury Playback within Premiere CC and After Effects CC

Hey, I am having trouble enabling GPU acceleration within Premiere Pro CC and After Effects CC. I followed online instructions on how to run the GPU sniffer and then alter a .txt file but the file path I am entering into Terminal is showing no results.
Any suggestions?

For Premiere Pro CC as long as the card has 1GB of VRAM you'll be able to enable GPU Mercury Playback. If under 1GB even modifying the text file will not work.

"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.

Video playback speed in After Effects

           After importing QuickTime video into After Effects it plays back at about half (or even slower) the initial frame rate (13 fps or so instead of 29.97 fps). Also in the top right corner of the workspace (Info Panel) I'm getting a message that "...Layer 1 Retrieving Frame".
           Could you, please, give me an advise how to return video playback to normal speed?
           Thank you.

          Sure, After Effects isn't a movie player. But it is possible to edit source footage in AE in order to make a coherent whole out of it, isn't it?
Technically possible, but not an ideal workflow. I can also cut through my filet mignon with a spoon, but I can do it a lot faster and with much less frustration if I use my steak knife.
I edit in Premiere and then use the Import>Adobe Premiere Pro Project option in After Effects to bring my edit into AE.

After Effects Error: RAM preview needs 2 or more frames to playback

I keep getting this error message on a Windows 7 64bit system with 12GB of RAM. I have tried rebooting and re-installing the application and After Effects still gives me this error message when I press '0' to perform a RAM preview
Any suggestions would be appreciated.

I would suspect that is the problem.... From what I gather, it uses H.264 compression inside MOVs, but it may use an unusual, non-standard profile and thus throw off AE. Can you check these settings in the extended info in the Quicktime Player? would help to know some more details. If you have Quicktime Pro, it may be enough to re-export the clip from there. Using identical settings, this should go pretty fast and not cause any changes in quality, but doing so may fix little annoyances commonlyy associated with such formats like open gaps or invalid timecode markers. If that doesn't help, then I guess it's time to run it through SUPER©, ffmpeg etc. to get workable converted files...

After Effects Playback 27 fps (Real Time) Audio is Slow

Hello,
I have Adobe After Effects CS 5 running on an HP Z600 8 core workstation (12 GB RAM) on Windows 7.
When I import any video AVI, MOV, etc and I preview with RAM the audio plays slow and it reports fps: 27 (real time)
When I link comps from premier I think it is causing lip sync issues.
My co-worker has the identical computer and when importing the same video, his reports fps: 29.97 (real time) and audio play fine.
I have looked around for settings that may affect this but nothing seems to help.
Multi-threading? Open GL issue?
Any Ideas?
Thanks,
Greg
