After Effects CS 5.5 MXF OP1a Audio Levels Problem

Hallo Forum,
Ich habe ein Problem, das mir großen Ärger bereitet hat. Ich habe einen 20sek TV-Spot in After Effects angelegt, welcher nach den aktuellen Broadcast Richtlinien (RTL Group) ausgespielt werden musste. Hier kurz die technischen Spezifikationen für den Upload:
[...]Als Wrapper- bzw. Containerformat wird ausschließlich ein MXF-Container mit dem
Kodierungsalgorithmus XDCAM HD 422 akzeptiert, wobei das Operational Pattern
1a (OP1a) verwendet werden muss. Die vom Quellsystem generierte MXF Datei
muss der SMPTE RDD09-2009 entsprechen.[...] Der Ton muss mit einer Auflösung von 24 Bit in mindestens zwei diskreten
Tonspuren vorliegen. [...] Die Aussteuerung der Tonsignale muss so erfolgen, dass eine Programmlautheit
(Target Level) von -23 LUFS (+/- 1 LU) erreicht wird.
Ein Preset für dieses Format ist in After Effects vorhanden (MXF - XDCam 50Mbits). Der Ton wurde von einem Tonstudio auf die verlangten -23 LUFS gepegelt. Ich habe das Audiofile (aiff) ohne weitere Anpassung unter die Compostion gelegt und mit dem Preset gerendert.
Problem: Ich bekam folgende Rückmeldung von der technischen Abnahme: "Der Lautheitspegel des Audiosignals liegt außerhalb des zulässigen Wertes. ( -23LUFS)! Festgestellt wurden -17,4 LUFS."
Ich kontrollierte draufhin die Lautstärke des Audiofiles und des ausgespielten TV-Spots (habe sogar extra nochmal im Tonstudio nachgefragt ob der Fehler nicht bei ihnen lag), und siehe da, die ausgespielte Sequenz war lauter als das ursprüngliche gepegelte Audiofile. Nach mehrmaliger Kontrolle ob ich nicht doch versehentlich den Pegel verändert habe, musste ich feststellen, dass das Problem beim rendern aus After Effects entsteht.
Zum Testen, bzw. die Lösung des Problems bestand darin, dass ich die Sequenz ausgespielt habe, in Avid Symphony per AMA Link importiert und das Audiofile zum Vergleich nochmal drunter gelegt habe. Ergebnis: After Effects hebt ungefragt den Pegel an.
Habe dann das gleiche MXF Format mit den gleichen Einstellungen aus AVID exportiert ---> Ergebnis keine Veränderung des Pegels.
Meine Frage ist jetzt:
Ist dieses Problem bekannt? Wurde es ggf. in CS6 behoben? Ich hoffe ich bin nicht der einzige dem dieser "Bug" aufgefallen ist, und hoffe das es ggf. gefixt wird.
Vielen Dank
Gruß VUCX

After Effects rendering with Format MXF OP1a 1080i/25, XDCAM with colour space "HDTV (Rec. 709) 16-235" but after rendering the colour space is "30-217"

Hello!
I have a very annoying problem in After Effects. I'm making an Animation with the format "MXF OP1A, Codec XDCAMHD 50 PAL (4:2:2)" with 8-Bit and with the colour space "HDTV (Rec. 709) 16-235" but after rendering the colour space is not 16-235, it is 30-217 RGB. After I activate the colour space in After Effects, then it shows the right values, but after rendering the value for white is 217 and for black is 30. Hopefully someone can help me. Thanks in advance.
Bye

Thanks for your answer, but i don't know an Adobe Media Composer, you surely mean Adobe Media Encoder, or not? Anyway i do not find the option for colour space in Media Encoder, so i would be very thankful if you could tell me where to find it.

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

Adobe after Effects CC Automatically Speeds up Clips/Audio

My Adobe After Effects CC Automatically Speeds Up Any Clip/Audio I drag Into It How Can I Fix This?

Without details I have no idea what's going on. It is not normal, but I don't know anything about your experience level, your system, your project, the type of audio file or anything else about your project. You might have just as well asked "Why is watermelon?"

After Effects rendering the video with the audio out of sync

so, the thing is, i did the animation on flash, exported it, put it on after to edit audio and what not, everything looks fine, previews are good, so, lets render!... every time i render the final video have the audio out of sync, specially the audio that is already on the first video. the video its originally on 12 fps, if i change the interpretation to 24fps, everything get worse. any help?

ok, both Flash and After effect are CS6, i have a Lenovo Ideapad, can handle 64 bits
first i exported the video on .MOV from Flash CS6, without any problems
Then i finished the edition on After Effects, everything look good.
i have tried to render it on MOV, AVI, MP4 and the audio for the video that was exported from flash always get out of sync. i dont really move anything else

After Effects CS5 crashes when impoting AIFF audio.

Hi,
AE CS5 keeps crashing me when I try to import AIFF audio. I've tried different clips rendered from different sources, but still it's crashing. The files are small and I have no problem processing HD video, so it's not a performance issue. Anyone having similar problems that might lend me some advice?
I'm running a MacPro 2 X 2.66 GHz Doal -Core Intel Xeon with 8 GB ram.
Update:
VERY STRANGE! I closed that project and created a new one and presto - audio imports fine. When I re-open the old project it still crashes when importing. I guess that's a work-around, so problem solved (?)...

Dynamic Link After Effects to Premiere (Video Only, No Audio)?

Can you Dynamic link an After Effects file so that audio does not interleave into the premiere pro project? I just want to link the video part of the comp and do not want audio data in my asset.
*I already know that I can double click the asset in premiere and drag video only from there. I want to strip audio from the after effects linked asset so when i drag the asset from the bin to the timeline it will not try to add audio also.
Thanks,
Cliff

If you unlink the audio and video in Premiere Pro
Then you select only the video layer to replace with After Effects Composition
You'll end up with the Audio automatically turned off in AE when the dynamic link composition is created.
You get the same result if you leave the audio layer linked but you lock it before enabling the dynamic link.
The advantage to doing this is that you don't have to mess with audio in After Effects. There is no additional disadvantage to locking or unlinking the audio track because any time you replace elements in PPro with AE compositions the Audio and Video are unlinked. You'll need to re-link them if you plan move the tracks around at all because you loose the out of sync warnings that you'll normally get.

Adobe After Effects CS6 cannot be opened because of a problem

Hi,
Sorry if I'm posting in the wrong place - I can't find sections navigation on these forums.
Running Mac OSX 10.8.5
I tried uninstalling AE CS6 and then reinstalling AE CS6 - same issue happened.
AE was working fine until I tried to open it today. It's probably been a couple weeks since I last used it.
I don't know if I'm able to get any help here. It' just an issue I don't know how to troubleshoot.

Todd,
Thank you so much for your help!
I am trying to follow your advice and install AE CS6 through the Creative Cloud application, but it seems that I can only install AE CC through the Creative Cloud application.
The text on this page ( http://helpx.adobe.com/creative-cloud/help/install-cc-and-cs6-apps.html ) seems to indicate that I can choose a version to download, but when I navigate to the linked download page ( https://creative.adobe.com/products/aftereffects ), I am not given the option to choose which version to download. I can only download AE CC through Creative Cloud.
Below is a screencap of what I see when I am on the download page - this differs from the screencap shown as an example on the page instructing me to go there.

My current version is Adobe After Effects CS6 11.0.3. It's problem is I can't update 13.02 version

I have a problem with After Effect version update because when I saved my After Effect project file at my Mac laptop, After Effect Verison was 11.0.3. So When I went to Mac desktop in edit suite room in University and tried open my project on the Mac desktop. The message pop out and said this project must be converted from version 11.0.3 (Macintosh 64). The original file will be unchanged. So Mac desktop have After Effect's version is 13.02 and I can't update my Mac laptop because I can' find After Effect 13.0.2 update file anywhere in the internet. so Can you help me to solve this problem, please because I will hand in my university assignment next month.
Thanks

Until your project is finished, you can ONLY work on it using your laptop. Don't try to work on it using a different machine.
Unless you RENT CS6 -- that is, you didn't purchase it, but pay a monthly fee to use it -- you won't have acess to 13.0.2.
This isn't a simple update -- this is installing a new VERSION of the software, and beginning with version 12, the software is rented.
So get your project done on your own machine, then worry about whether or not you should incur a monthly expense to have the latest version of AE. Don't change horses in mid-stream!
Now, there IS a way to work on both your laptop and that other machine, but it is downright messy! It also involves having access to AE Creative Cloud (aka Version 12) on that machine -- so until you can confirm that fact, I'm not even going to describe the messy process.
I stick to my original advice -- keep the project on the laptop unless you enjoy missing deadlines. Or due dates.

Raise audio level problem?

When adding gain to a clip on the timeline no matter what function I use, volume effect, raise track or clip level, I seem to invoke auto audio gain. The audio level, (amplitude) slowly raises during pauses? Any way to defeat this?

I'm not sure I understand. Can you elaborate?

After Effects CS4 freezing with RAM preview audio?

Firstly, I'm on a mac. This problem just started a few hours ago after I made some system updates. When I hit preview in a comp with audio it runs through the frames, then locks up when it would normally start playing. I just get that dang spinning beach ball of doom. If I turn off the audio on the layer, it previews fine. I believe the only think I had updated when this problem began was upgrading to quicktime 7.6.2. Would this effect the RAM preview? Since the problem, I've updated AE to 9.0.2 and OS 10.5.7 with no change.
Anyone come across something similar?
Thanks

Mmh, well, seems ominous, but quite obviously QT is somehow involved. do you use any dedicated video hardware such as AJA or BMD cards? If so, the QT update may have introduced an incompatibilty with their drivers... Even if not using any such equipemnt, definitely check your QT system control panel. Also use OnyX to flush your QT components cache. They may just need to re-initilaized to function properly. Short of that I'm not aware of such issues, but anything is possible. If the issue persists, using Pacifist and downgrading your QT may be the only option. What Mac are you on exactly?

After Effects wont let me scrub through audio or render it in one project, why is this?

Only 1 project has this problem when I open it up. It uses more content than others, but when I delete that content and leave just the audio in, it still wont play. Then I open a new project and insert a music track... and suddenly there's sound. Obviously I'm using ram preview with sound, and output options are correct, and it's not muted... I have 16gb of ram on my macbook pro, so having too many resources can't be the problem.

It's mp3, but when I created a new project and imported this audio file it was fine, just not in my original project.
Forgot to mention that when I open the project it says there are 3 missing effects, I started the prject on my PC and brought it over. But when I did that, the sound still worked... while some plugins obviously didn't carry over. Says it's missing a font family from text layer too, but that didn't effect anything last time either. Iswitched the fonts just in case it was and deleted those effects, but nothing changed. Whatever happened the last time I opened this project months ago, something happened that caused this.

After Effects CC 2014 plays/renders incorrect audio for mp3 (Mac OS X Yosemite)

Hi,
I'm translating the audio for a number of animations made in AE. Sometimes when the mac users import new audio in another language, AE plays and renders a totally different mp3 file than what has been imported. It is playing another piece of translated audio from another folder but I can't tell where from (as it's in another language).
When I click reveal in Finder, the track in Finder plays the correct audio.
When I re-import after purging and emptying caches, AE still plays the wrong audio.
I found a work around where if I copy and re-name the audio and import that it works. The problem is, we can't tell when this has occurred until reviews have been performed and it's costing us a lot of time in re-renders and fixing.
Does anyone know what causes this problem? Has anyone even encountered it?
Any advice is much appreciated.

Does anyone know what causes this problem?
Sure: You are using MP3 files. AE never has been good with them. Convert them to WAV/ AIFF.

After Effects isn't rendering out the audio in my video?

I have the audio output box checked and the same exact setting is working for every other Mac in the office. I just don't get it.

There could be a lot of reasons for this.
Your video may not have an audio track: either no audio at all, or the audio is embedded in the video track; AE needs a separate track.
You may have the audio turned off: check for a little speaker icon with the layer in the timeline, and turn it on.
You may have compressed audio -- mp3, ac3, etc -- and AE doesn't play nicely with it. Turn them into aiff or wav files.
You didn't say where you're noticing this lack of audio: in AE, or after rendering.
....aaaaand it's tough to know the location of that audio output box you checked, because you didn't say.

After Effects CC GoPro Footage In Point / Out Point Problem

On the left you have the imported video made by GoPro hero 3, imported intto AF cs6. On the right.. The same Video imported to AF CC latest version.
For some reason. AF CC screws up the timecode of the video and i cannot figure out why. Moreover... when exporting Camera tracker from GoPro video to Cinema4d... the camera is not working.
Any help would be welcome.
Kind Regards
Ivan

when exporting Camera tracker from GoPro video to Cinema4d... the camera is not working.
That would require to see the shot, but based on the thumbnail it's pretty obvious that the shot may not at all be suitable for 3D tracking and solving to a logical 3D camera. I don't see a timecode issue, either. Depending on how those cameras actually store it and maintain their counter, it seems perfectly logical. CS6 may just not have fully supported the source timecode and thus reverted to its default behavior defining the beginning as zero.
