After Effects CS6 - mp4 file error

Initially I struggled to get After Effects to import footage that was shot with a Sony F3 (mp4 codec)
I got it right eventually, don’t know how but it worked fine for more than a month.
This afternoon however it just refused to work and I get the standard error saying the file is damaged or unsupported.
I checked the forum but can’t seem to find a solution the problem. A couple of people suggested that the footage be converted to another format.
So I have 2 questions:
1. Is this a bug in CS6?
2. What other format can I convert the footage to without losing any quality that will play in After Effects.
Regards
IvanRisingStar

The files only open in VLC Media Player.
Neither Quicktime nor Windows Media Player want to play the file (.mp4 - Sony F3)
I don't know what changed since but it's very frustrating.
I have found a workaround though. I re-encode it using Adobe Media Encoder. I just have to go back into the Premiere project and replace the recoded files with the old .mp4 footage.

After effects cs6 trial install errors

Hello,
I am trying to install the trial version of After effects cs6. I installed the entire cs6 master suite and everything worked except after effects. I tried again from the master suite and then with a separate after effects only installer(all from adobe's site) always getting the same results
here is the error summary:
I am trying to install on a new macbook retina, I had installed the CC trial but it has run out. maybe I need to uninstall Creative cloud, but all the other programs installed with no problems so i am not sure why its just after effects.

Thanks so much for your help, but i am encountering some issues with the log. In the link you posted I was directed to look for the log in library>logs>adobe>installers and that the file would consist of the product name/install date and end in .log.gz
However I can't find and file that meets this description or even an installers folder inside the adobe folder
^this is all that is in the adobe folder, and both these folders are empty.
There is another folder called adobe downloads which contains these files
which still don't really fit the description provided.
am i doing something wrong? or should i look somewhere else?
thanks again

After Effects CS6 ScriptUI Initialization Error

So I've received:
After Effects warning: Au error was encountered attempting to initialize ScriptUI. {Initialization error" - Initialization error 'ApplicationEnvironment::scriptUIFlexSWFPath is not a valid pathname'}
Nothing I have tried has worked to fix this. I trashed the preferences, even uninstalled and reinstalled After Effects. Does anyone have any suggestions or know what's going on?
Thanks!

Hi Jonas,
I've spoken to the lecture who knows more about the software and this was his reply:
The students will be using files captured from multiple devices dependent on what they have access to. Mobile phone, flip cameras, HD cameras etc. Which will use different codecs. I do request students to export their work as .mov using the H.264 codec and that process hasn't thrown up any problems so far - but that is export not import.
The lecturer also mentioned students cannot import audio either.
The operating system is Lion 10.7.5.
Adobe After Effects CS6 version 11.0. I've installed updates on one of the macs 11.01 and 11.02 but doesn't resolve the problem
Mac Spec
3.2GHz Intel core i3
Memory 8 GB 1333mhz DDR 3
Graphics ATI Radeon HD 5670 512mb
Hard drive 350 GB
The other software installed on this machince is the Adobe CS6 Design Suite and Microsoft office and we dont use any third-party hardware.
They only devices that are attached to the Mac are camera,USB Pens and External Hard drives but these are all removable are are not permanently attached.

After Effects CS6 - render files huge!

Ok I am tying myself in knots here.
I have a 7 second text animation on a plain background in After Effects CS6 which I want to export so I can use it in Premiere Pro CS6 withan alpha channel so i can superimpose it over video. The file is 1080P 25 because that matches my video. the first time I rendered it it came out at 89Mb which was fine. But I wanted to tweak the text positioning so I did that - now every time I render the file is around 1.5Gb!
I am using Windows so i can't render Quicktime with an alpha channel which means I have to use avi but what settings should I use? (Avi is the only format which allows me to export RGB + alpha).
I have to say that I have used many video programs in my life but I find After Effects the single most unituitive piece of software I have ever encountered. Why can't it give you an indication of how big your render file is likely to be to gvie youa t least some clue as to what settings to use?

That is not correct.
You can install QuickTime on Windows and use QuickTime for output from After Effects.

After Effects CS6 - Project Files Virused?

Guys,
I'm collaborating on a stereo TV show with several other CG artists (living around the U.S.), and one of them has been complaining for months now about how his AE project files (created with CS6, running under Windows 8 64-bit) have gotten huge, and take literally hours to load. He then shipped us the files for us to examine.
Here's the deal: one of his .AEP files clocks in at 222 megs, and when I loaded it into my copy of CS6 (running on a dual Xeon machine, Windows 7 64-bit, 32G of RAM), it took 45 minutes to load. (Another one of our artists, working on a Power Mac, tried loading a different project created by this guy, and it took 10 hours to load.)
I then proceeded to completely rebuild his comp in my copy of AE CC -- I loaded all his original footage (a combination of 32-bit .EXRs, .PNGs, .TIFs and .TGAs), set up the layers and effects filters exactly like his, and then resaved my file.
Result: my file is 2 megs in size -- 1/100th the size of his file -- and it loads on my machine in 5 seconds.
Has anyone ever heard of something like this? I'm wondering if somehow a virus or Trojan put an enormous amount of spurious data in these files, or if they were somehow created with a cracked version of AE or some other plugin, and our legit copies of AE are brought to a standstill with his bad .AEP files. (Note: I scanned his files and footage with Avast Antivirus, MalwareBytes and the Windows Malicious Software Removal tool, and came up with nothing.)
Here's the other weird thing: I loaded one of his project files, then started deleting layers, footage, and comps, and kept resaving the project and checking the file size. Even after I deleted every single element in the project -- it was completely empty -- and saved it, the file size went down from 222 megs to only 214 (and that empty project file still took 45 minutes to load.) I saved this empty project as an .XML (.aepx) file, and that file is 430 megs!
What in the world is going on here? We really need to figure this out, because it's destroyed our productivity on this show having to rebuild these comps. Thanks,

Guys, all the footage is CG and was rendered from Lightwave -- there was no live-action footage to "camera track" or "stabilize."
Second, most of these comps don't even use a camera inside of AE -- they're 2D comps entirely.
And again, as an experiment, I deleted literally everything in the comp and saved a completely empty project, and the file was still huge and took 45 minutes to load. How can that be?
I would really love to send one of these files to Adobe and have you guys load it into a debug version of AE CS6 to see if you can identify what the problem is. Thanks,

Where is the Warp Stabilizer plugin located in After Effects CS6 program files?

I need to delete the plugin temporarily to gain access to my project because it constantly crashes on start up due to the Warp Stabilizer.

NOt sure if you can actually remove it,but it should be in the plugins/extensions sub-folder inside the AE install folder. Anyway, try the usual troubleshooting first before taking such a radical step that may destroy AE and require a reinstall. Flush the caches, open the project with capslock and remove the effect.

Uninstal and re-install.
Uninstall, clear avery adobe product, remove paths and traces, relaunch, and then re-install.
Same as step 2, with firewall turned off, Anti-virus removed.
Run installation with Administrator rights.
Launch program via Compatibility settines Vista, Vista SP1, Vista SP2, Windows 7
All drivers are updated and reupdated.
Re-installed all GPU drivers.
Refreshed my Wndows 8 OS.
Reformated my Windows 8 OS then Installed AE cs6.
Installed AE on my F drive instead of C [C drive is an SSD and F Drive is an HDD]
I am able to see the AE CS6 splash screen but it will prompt a message "Has Stopped Working".
Other things to take note:
I am able to launch Renderer Machine without any issues.
I am also able to launch other Adobe Products that came along with AE CS6 try version.
Latest Quicktime version is installed.

Hi Todd,
Thanks you for replying.
After updating to 11.0.2, I am still unable to launch AE CS6.

Adobe After Effects CS6 keeps crashing before it even starts

So like a year ago I purchased adobe after effects. I used it almost every day till about 2 months ago till I started using another video editing program. So for 2 months I did not open AE. Today I felt like using it because I felt it would do a better job that sony vegas so I tried to open it. It brought up the purple icon and it gave me an error. ''After Effects error:Crash in progress. Last logged message was (number here changes every time i do it) <dynamiclink> <5> c:/program files/adobe/adobe after effects cs6/support files/32/dynamiclinkmanger.exe. after this messege it just automatically exits after saying it crashed. I really need it to work since my final for college depends on it. I tried to uninstall it several times with numerous programs but none work. Whats wrong? how do i fix it ? is their a file or something missing? i looked on updates on adobe bridge and it said i was up to date. In addition i manualy tried to download an update and when i tried to open the update file it would open up af and display the same messege. any suggestions welcomed. thanks

The short version is that you either have changed your graphics setup, messed up your CoDecs, done something weird to your media cache or have permissions/ security issues or whatever. Since you failed to provide any system information we can't be any more specific.

Dynamiclinkmanager.exe crash on startup: After Effects CS6

Every now and then Adobe Application Manager uninstalls itself for some reason, and when this happens Premiere Pro and After Effects don't work. I then quickly reinstall it and Premiere Pro works fine but After Effects does not. I get this error: "After Effects error: Crash in progress. Last logged message was: <5092> <DynamicLink> <5> F:\Adobe After Effects\Adobe After Effects CS6\Support Files\32\dynamiclinkmanager.exe" and then when I click OK this pops up: "After Effects can't continue: sorry, After Effects has crashed. For After Effects Help and Support...." and so on. I don't know if it matters but at the bottom of this box it says "(0::42)". After that point it says "Adobe After Effects CS6 has stopped working" and the usual pops up. Can you give me any feedback, I don't know what's wrong with it. I heard some things like delete the prefs file and that didn't work. I look forward to hearing from you. Thank you. (and yes, that location is where I have Adobe After Effects installed, my main drive is out of space.)

You need to install After Effects on your C: drive.
Also, you need to install the bug-fix updates. You are running version 11.0.0, not 11.0.4. Updates: http://adobe.ly/DVA_updates

After effects CS6 error file cannot be imported - this 'moov' file is damaged or unsupported

Hi there,
I'm working in After Effects CS6 (11.0.2.11)
I imported an AAF that was exported from Avid MC 6.5.2. I colour corrected and graded the sequence using colorista 2 and magic bullet looks and some other native AE FX.
Before exporting I decided to double check something to do with the audio. I imported the same AAF into FCP 7, took a quick look, but decided nothing needed to be done. I tabbed back to AE (which was left open), and upon returning, AE started giving me all these 'damaged or unsupported' errors.
Subsequently, AE will now not import any quicktime movies - even ones I rendered out of after effects earlier in the day (these quicktimes use ProRes422 codecs, animation codecs and other lossless codecs)
I've restarted, re-exported the AAF several times using diff settings, uninstalled perian... but to no success.
Anyone got any good ideas? I've had this happen before, where AE will import an AAF and it works first time no problem. Then something happens when I re-open the project and boom... 'moov' errors. It's really odd and very annoying - esp since it now won't import other normal quicktime movies too - with the animation codec. I have quicktime 7 pro installed and quicktime X on Mountain Lion (OS 10.8.3).

System Details: MacPro (OS10.8.3) 2 x 2.93GHz 6-Core Intel Xeon, 24GB RAM, Radeon HD 5870 1GB

I have the exact same problem on a Mac with 10.8.3 and After Effects from the Adobe CS6 MasterCollection (AE 11.0.2.11 (german)): all of a sudden I cannot import any native QuickTime-Movies (ProRes, Animation) or even movies that use e.g. H264 in a QuickTime container. Even projects that worked 2 days ago that contain QuickTime-movies will not open anymore.
This happened 2 days ago without any action from me that I can think of that could have caused this. I did not install any new codecs or plugins, nor was there anything in the apple software update.
What I tried/checked so far (to no avail):
disks are OK,
file permissions are OK,
no Firewall is blocking anything,
deleted AE-prefs,
removed all 3rd-party plugins,
removed all 3rd-party codecs.
Edit: I did some further poking around, and it turns out that after deleting or resetting file permissions of the folder "~/Library/Preferences/Adobe/After Effects" AE will briefly allow you to open an existing project that contains QT-movies. If you then try to import any QT-movie you get the error message -- and after that you cannot open the project again.
This is really bad -- AE is basically unusable right now.
P.S.: The (german) error-message is this: "After Effects Fehler: Die Datei "filname.mov" kann nicht importiert werden: Datei "MooV" ist entweder beschädigt oder wird nicht unterstützt."

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.
