After Effects CC 2014.0.2 rendering slower than previous version with identical settings

Is this a known issue? Can't find confirmation just some mention of it.
I'm on an 27" iMac with 32GB Ram and SSD. Latest OSX. Latest After Effects.
I first noticed after accidentally opening a file in CC2014 when asked to supply a client a render. It takes almost 3 times longer to render a file. I've checked preferences on latest on and previous version of AE and everything seems identical. Am I going mad?
I guess I could stay on the previous version for a while but hardly ideal as I'm paying for access to the latest versions and need to move up eventually.
Help much appreciated.
Anthony

Yes everything is identical. I setup a file ready to render and opened it in each version and rendered. I did this with an old large project file and also a new test file with a very simple 2 minute loop of a square moving left to right.
Beginning to hope the upcoming update fixes it somehow though would prefer to fix and learn something from this...

  • Adobe After Effects CC 2014 Multi-machine rendering does not create RCF after Collect-File

    This was working in the previous release.  After going through all of the steps to perform a multi-machine render, not only does it say it is limiting it to 5 machines instead of the usual 99 (and I have over 100 cores on the render farm) but "Collect Files" (File/Dependencies/Collect Files) does not create the Render Control File (RCF) that kicks off the process on the other machines, like it did before and is supposed to do.
    This release was supposed to fix the 32 core limitation on render nodes (my server has 48), but now does nothing at all.
    Anyway, I assume there is a check box somewhere that says "do something" that hasn't been checked and another that says "Maybe my machine has more than 5 cores", and I would appreciate being steered in the direction of these new mis-features.
    Just as background, the 48 core server does show the little TV screen that monitors the watch folder, and I know for a fact that process looks for the "RCF" file.  Looking at the directory specified for "collect files", I can see that no RCF file is created, only 1 file, a report.txt file which contains this information is produced:

  • Render file size bigger After Effects CC 2014

    Hello, this seems like a silly question, but ever since the 'After Effects CC 2014' update my rendered files seem to be enormous in comparison to the files I rendered before the update!
    I don't see why the update would have adjusted my render preferences, but it must have done as a 2min clip that rendered at 140mb before is now 10GB!!!
    My knowledge of codecs and compression is limited but I had a good preset before the update which now seems to have changed (although I have always been rendering h.264/full quality/no audio so I don't understand how the file size can change so drastically).
    Has anyone else experienced anything similar?
    If not could you please advise me on how to render these files to a suitable size. Like I said they need to be h.264, 1920 x 1080 with no audio.
    Thanks.

    After Effects CC 2014 no longer supports the output of many delivery codecs, such as Mpeg4 and H264, through the Render Queue.
    You can output far more formats, and in greater quality, using Adobe Media Encoder.  You can send AE renders directly to AME from After Effects.  You can import AE projects directly into AME.  And you can also render high quality and/or lossless formats from the AE Render Queue and then re-encode them from AME.

  • No Refreshed Interface Design in After Effects CC 2014

    Sort of an odd question, but how do you change the interface design in After Effects CC 2014 to be the new "Refreshed Interface Design"? Like with the blue text color, borders, and different look panels (as seen in the first image linked). I updated to Adobe After Effects CC 2014 yesterday, and for some reason, my interface design has not changed at all. Is there somewhere in preferences where I can change this? I would appreciate any help, thanks.

    Your second image shows After Effects CC 2014 (13.0). The new UI comes with After Effects CC 2014 (13.1).
    I'm curious about how, exactly, you installed the software, since you should have gotten After Effects CC 2014 (13.1.1) if you installed from the Creative Cloud service.

  • Slow rendering in After Effects CC 2014

    I'm using Adobe After Effects CC 2014.02 on a Macbook pro with 10.9.3 OSX installed.
    I need to render a composition that is 3 minutes long, without any special effects or video. It's just a 500 mb Photoshop file with some movements. This takes anywhere from 7 to 30 hours to render. I rendered a similar composition before and this only lasted 20 minutes. Rendering it at a third of the quality only takes a couple of minutes, so the 7 to 30 hours seem excessive.
    These are the memory settings:
    Installed RAM: 16,00 GB
    Current RAM Usage: 9,64 GB
    Allowed RAM Usage: 11,00 GB

    Tried clearing disk and media cache, boosting RAM and installed CUDA, but nothing worked. What could be the problem?

    NVIDIA GeForce GT 650M 1024 MB graphics
    The time it takes to render is the same in CC. Flattening the file in Photoshop is not an option, since I need all the different layers.
    The strange thing is that the first video I made using After Effects rendered fine, while the second one (and the third I'm working on now) are not. So I would think my computer is capable of doing this and it has to be something to do with a setting somewhere. Also, I sent someone on a Windows computer the files and the composition rendered within 20 minutes.

  • Workaround for slow performance and poor resolution with RED R3D files in After Effects CC 2014 (13.0)

    The After Effects team are investigating a bug in After Effects CC 2104 (13.0) where RED (.R3D) files are very slow and the image resolution is poor, about 1/8 sampling.
    The following workaround has been reported to solve the problems in some cases:
    Save the project.
    Choose Edit > Purge > All Memory & Disk Cache.
    Please post in this thread about whether or not this workaround helped you.

  • After Effects CC 2014 - Rendering / saving project file to CS6

    Hello all,
    I'm writing here to try to understand the st**** decision to exclude mp4 and mpeg from the render possibilities from After Effects CC 2014. I would gladly go back to CS6 but as of now I have more than 40 hours of edited video project in CC 2014, which of course cannot save project files to CS6, which is another brilliant move by somebody in Adobe that has the title position of "the dude for giving ideas to p*** people off". Now the problem is this, if I choose to export just a single clip from my composition of course I cannot export it to a container and codec of my choosing since it cannot be exported to Media Encoder, and has to be done in After Effects or I have to make a composition for each and every file, in order to export it to to the Media Encoder.
    Now I ask you good people any way to move my projects back to CS6, remove this unusable piece of software and be over with it, I simply don't have the time to be toying around with Adobe's new found glory for Apple and exporting stuff to QuickTime, taking 3 times longer than mpeg. Tried with OpenSeasame and by just exporting an XML file but none work so if there is any other way please let me know.
    Good thing I only got 1 month and didn't pay for the whole year...
    Cheers,
    shorto

    Did you use any of the new features in either AE CC (the original one) or CC 2014?  If yes, you're kinda stuck.
    If no, you'd have to engage in a two-step process: backsave the AE CC 2014 project to AE CC, then open the project in AE CC and backsave to CS6.

  • After Effects CC 2014 crashing on startup

    I downloaded the trial version of After Effects. By downloading it, it activated a 30-day trial. However, every time I try to start up the program, it gives me an error and crashes. I read on the forums issues about fonts and OpenGL, but it doesn't even give me detailed information on the crash. Anybody able to give me a bit of an assist on this? I use Adobe Design and Web Premium CS6 on my PC. I primarily use Sony Vegas for my video work, however I was sent a file on AE and rather than get in contact with the client to have them resend it in .veg, I figured I could download the trial and open it there. No such luck. I've finished the work, but now this AE issue is just bugging me. I am interested in trying it, but if I can't get into the trial, it really curbs my interest in the program.

  • After effects CC 2014 transparency properties of pre comps, collapse transformation on, no longer keyframeable???!!!

    Hey there,
    lately I'm using After effects CC 2014. Now I had to make the experience, after optimizing (collapse transformation) the pre comp, the global property transparency is no longer working.
    I can make keyframes but the pre comp acts like my easy ease keyframes are hold keyframes. Btw if the collapse transformation button is unchecked it works fine but than i don't have the optimization features. It's a catch 22. Sure, I can go into my pre comp and set the keyframes there, but this is pretty annoying and seriously not the way to work.
    So is that a bug in CC 2014?
    Help is needed.

    Layer styles render in a different order so lots of things can get fouled up with you use them. They are still usable in complex situations, you just have to apply them in the right place in your composite. I've never found a situation where I needed a Layer Style and another effect that I have not been able to work around the limitation.
    There are other things that change the render order. After Effects only does one thing at a time. The basic render order is listed right in the timeline view. Here's a sample.
    Basic effect with Layer Style turned off:
    First Mask 1 is applied to the layer, then Mask 2 is subtracted creating the hole
    Then Fast Blur is applied, then Bevil Edges to create the button with the soft edges
    Then the Transform controls take over and the anchor point is evaluated, the position reported, then the scale, then the rotation, and finally the opacity
    Then the Layer Style is applied.
    In my button design I want to apply a stroke to the button so that I looks like this but with the soft base and a stroke on the inside hole:
    But, as you can see I had to turn off the Fast Blur to get the stroke to work because the Layer Style Stroke is calculated from the alpha channel, which fast blur has made 76 pixels wide so with Fast Blur on I get this:
    The solution to my problem is to pre-compose and add the layer style to the pre-comp, then use an adjustment layer with masks for the fast blur to get what I wanted in the first place:
    So here's what AE is doing with the final project.
    The background layer is rendered
    The pre comp is added to the mix
    Inside the pre-comp the layer is rendered
    Mask 1 is added to give rounded corners
    Mask 2 is subtracted to punch the hole
    Layer styles are applied to add the stroke
    Back in the main comp the pre-comp is rendered
    Bevel Edges is applied to the pre-comp using the alpha chanel
    Now the adjustment layer is added to the mix
    Mask 1 is added and this limits the area in the underlying layers where effects applied to the adjustment layer will  work
    Mask 2 is subtracted from the adjustment layer poking a hole in the effects
    The fast Blur is added blurring only the bottom edge of the button
    There you have it. An in depth tutorial on the rendering order in AE and how to use nesting and pre-comps to reorder effects to get what you want.

  • After Effects CC (2014) MacPro Performance??

    I just installed the new After Effects CC (2014) on my 2013 MP with 2 D700s.  I am not noticing any significant difference from the previous version of AE.  GPUs are still showing as 2GB of VRAM (see below).  I dropped in a 5K (5120x2700) R3D clip into a 1080p comp, scaled to width and tried to move the playhead, let alone play and it is extremely sluggish (media is on a G-Raid).  Even at "low" debayer and 1/4 res I seem to max out at 20fps without ram previewing.  Mercury Transmit is off, both "Viewer Quality" options are set to "Faster".  Even with a 1080p ProResHQ file I can't get realtime playback without ram previewing.

    Tim,
    Thank you for the replies.
    Is this to say that to simply play a quicktime video file (no effects or adjustments made) in After Effects the expected behaviour is that it must be RAM previewed?
    This is how After Effects currently works. It hasn't changed in many years. You can initiate playback without RAM Preview (press spacebar), but the playback speed will depend on how fast the frames can be cached to memory for playback, and will very likely not be real-time except for the simplest of comps.
    This is exactly the change that I am looking for.  In my opinion, "the simplest of comps" would be things like "a comp with a QT file and no effects/adjustments", "an Illustrator file moving in the example of a credit roll".  Hopefully this will all be improved upon in future releases.  I am looking forward to seeing them.
    As per the After Effects blog post a few months ago about future improvements all that I (and I am confident that the majority of users will agree) would like to see is for After Effects to be significantly faster (think the improvement to the "search" feature in Premiere).
    We also want to make After Effects faster. As I mentioned, we are currently focused on performance-related improvements to After Effects. The blog post you referenced was written while we were in the middle of developing the After Effects CC 2014 (13.0) release, and beginning to think about our next release. A side note here: performance in After Effects includes both rendering performance and interactive performance; that is, how fast After Effects allows you to work.
    I will anxiously await these updates.  As a note: I feel that interactive performance is a higher priority than rendering performance.
    During the CC2014 release presentation on video there were multiple references to "not waiting for renders", except this is exactly what you have to do when working in After Effects.
    Can you be more specific about what context you saw this in? Can you provide a link? "Not waiting for renders" is a fairly generic statement, so context is important. It may have been used in connection with the new text templates feature in After Effects CC 2014, which allows faster workflows between Premiere Pro and After Effects, or with Dynamic Link in general. Otherwise, I need to know how that phrase was used in order to understand your perception of it.
    Yes, the context was always in relation to either dynamic linking with PPro, or Direct linking betweens PPro and SpeedGrade.  However, the overall impression I got was that Adobe's goal with the video applications was to improve the interactive performance so that users can focus more on being creative and less on waiting for the software.
    Could you please also address the issue of After Effects still recognizing the MacPro GPUs as having 2GB of memory instead of 12GB?
    We have a bug open on this and are investigating.
    Thank you.  I was really hoping that the 2014 release would fix this, but understand that it is likely quite complicated and there are many other improvements/bug fixes that the team is working on.  Are there any updates on when this expected?  Is this effecting performance or just simply the readout in After Effects' GPU information.
    I greatly appreciate you taking the time to address all of these concerns and am looking forward to the continued updates to the entire CC video suite.

  • After Effects CC 2014 Crashing with Magic Bullet Looks on Mac

    Hi,
    I recently installed the upgrade to the latest After Effects CC 2014 v13.0 and found the Magic Bullet Looks now causes After Effects to crash. I'm using MBL v2.5.2
    I opened the Activity Monitor and noticed that whenever the crash occurs the Adobe QT32 Server is in a state of (Not Responding)
    On a clip I can apply the MBL plugin with no problems and even if I am copying a previously set up version from a previous clip, it applies and renders without trouble. I can click "Edit" on the plugin controls, open up the MBL control window and make all the adjustments I need without any trouble. The issue is when I then click either "Finished" or "Cancel" to go back to After Effects. The program freezes and I get the spinning wheel of death for about ten seconds and the the whole thing, MBL and AE shut down.
    I am running:
    MacBook Pro
    OS 10.9.4
    Processor  2.3 GHz Intel Core i72.3 GHz Intel Core i7
    Memory  8 GB 1333 MHz DDR3
    Graphics  AMD Radeon HD 6750M 1024 MB
    Cuda  6.0.54
    The footage is Apple Quicktime ProRes HQ
    I have Quicktime v10.3 installed and Quicktime Pro v7.6.6
    I am at a loss as of how to fix or even work around this. Any help would be appreciated.
    Thanks

    There was a bug in MBL on Premiere CC 2014 that was causing crashing and lockups. Red Giant released an update quite quickly that so far seems to have fixed it for me. I know you're talking about AE but maybe there's some common code that was also fixed? As Rick says, have you checked the latest ver of MBL?

  • After Effects CC 2014 Graphics Card Issues?

    I just updated to After Effects CC 2014 the other day and have been having issues with it accepting my graphics card.
    I worked with AE CC before this with this card and haven't had any issues. The program will not use the graphics card for any ray traced rendering. The error message that I get at startup of after effects says "Ray Tracing on the GPU requires an approved NVIDIA graphics card and CUDA 5.0 or later." I have CUDA 6.0.37 installed

  • After Effects CC 2014 - Crash on launch

    At first - I've read all topics with that problem , and it doesn't work correctly.
    I bought After Effects as Single Application yesterday. And I'm very sad, because of this problem. Can anyone help me?
    I've tried this - CC Applications crash immediately after launch . It did not make any difference.
    I can see the work space of After Effects at start for a slit second before crash. And then my window are makins smaller with crash. But it doesn't save any crash logs. I tried to fix it.
    I've reinstalled program something about 5-6 times. I used Cleaner Tool too...

    Ram = 8GB
    CPU Intel Core i5-2450M @ 2,50 GHz
    One monitor, disc drive.
    NVIDIA GeForce GT 525M
    I have the newest drivers.
    I have QuickTime (newest).
    I'm running skype/chrome like other software.
    I'm using OpenGL.
    I'm not using Ray Traced 3D,( because my After Effect don't work correctly).
    I think that's enough.

  • Custom Pixel Aspect Ratio (After Effects CC 2014)

    Hi All,
    How do you create a custom Pixel Aspect Ratio for After Effects CC 2014. I need a PAR of 3.3, as it would help me solve a technical problem i've been having with projection mapping.
    I've tried editing the Interpretation Rules.txt file which was hidden within the Users\Appdata\Roaming\Adobe\After Effects\13.1 Folder. To remove the last # so i can at least see that I can set up a custom PAR.
    But it doesn't appear in the drop down menu when creating a comp, or interpreting footage.
    I've also made the same change to the Interpretation Rules.txt file in the Premiere PRO CC 2014\Plug-ins\en_US\ folder.
    And I've restarted my PC after changes just incase Media Core wasn't updating itself properly.
    I can see the Custom PAR as an export option out of Media Encoder. But thats not what i need. I need to be able to correct a render which had a PAR of 3.3 without losing pixel information, much like an Anamorphic workflow.
    Anyway, Any help would be appreciated.
    Thanks!

    Hi Rick,
    You're right, it's no known PAR... completely arbitrary and custom to this particular job. I'll run you through my process.
    I have a projection surface (a basketball court) Which needs to have content designed onto it which is viewable from one perspective point (camera 1) in the stadium. The problem is that Camera 1's viewing angle to the court is quite shallow.
    This is what Camera 1 sees:
    I will be generating like this for the surface so that it looks like a deep 3d surface from "camera 1"
    Now, the problem is that when I perspective correct the renders to fit what the projector will be projecting from straight down. There isn't enough pixel information for the height of the image. Meaning the pixels will smear.
    This is the image that would be projected from a top mounted projector to achieve the 3d effect from the image above, you can see the loss of information in the the height pixels.
    My solution for getting more information into the height is to render out of our 3d packages with a Pixel Aspect Ratio of 3.3. This was the sweet spot I found to get enough pixel information to match the pixel output of the projectors.
    The resulting render looks like this (note, the angle of the camera hasn't changed)
    As you can see, there is more height detail now, which will mean that that last row of pixels will be remain fairly sharp.
    So, at this point, I can render from my 3d applications, and conform to the projector dimensions, with very little information loss in the height of the projected image, and without compromising my 3d persepctive.
    I'm using the plugin "Camera Mapper" to project this render onto a plane which gets me the full frame of the projector at the right resolution, 4608 x 2304
    The tricky part how to composite elements into the scene in an intuitive way.
    If i want a horse to look like its jumping through the scene from "camera 1", like this:
    Then in the that contains all the information, It will look like this:
    Now that's all well and good, but it'll be harder to create realistic looking effects from this view, because they'll all need to be stretched.
    I'd like to retain all the image information and just view the comp as though it's squished down.
    I imagine this could be done easily by changing the comp settings to a PAR of 3.3.
    That way, all the pixel information remains, but i can design in a realistically proportioned composition.
    I hope that gets you up to speed on my issue, and my request for a solution.
    So, in summary. I'll I'm really looking for is a way to customise the PAR options so that I have a custom available that I can apply to this, and only this scene.
    Does this makes sense?
    Cheers,
    Evan
