Audio in After Effects 8 CS3

Apr 21, 2008 3:22 PM

when you want to play the clip back, how do you make it so its like a regular editing software where you can mess around with the audio as well? or do you need to do it in like premiere pro or something?

    Not exactly sure what you're getting at.. If you have a movie file that contains both video and audio and want to edit the 2 items seperately, make a duplicate, name them appropriately (video, audio), turn the audio icon off on the video one, and turn the video eye icon off on the audio one. Then you can cut, slice and edit it to your heart's content.

    to view waveform, hit ll (2 L's fast)

    To play just audio hit . (period on numpad)
    To play video and audio - 0 on numpad
    to scrub audio, hold ctrl and drag current time indicator

    You press play by hitting spacebar? Don't - you need to rampreview it (0 on numpad) in order to hear audio and play video at realtime. To confirm, you pressed 0 (zero) and . (period) on the numpad, and neither played the audio? If you select your audio layer and hit ll, do you see the audio waveform? Also, make sure audio is enabled in the time control window.

    Sounds like you need to do some reading.

    Check the manual on Audio Previews, or view online LiveDocs here:

    "but there is not even an audio box "

    Means you ain't got no audio.... Verify that is true by trying to play it in another program. What format is it?

    Sami, please do some reading up. AVI is not AVI. It all comes down to the CoDecs used for the compression. If AE says there is no audio, then the compression used for the audio stream is incompatible and thus disabled. It's as simple as that. It has absolutely no relevance whether the clip plays in other tools. In such cases you simply convert the file externally in VirtualDub, SUPER© or whatevcer tool you prefer and extract a WAV file from it.

    Likewise, MP3 is not MP3. AE support's the clean spec, not any custom extensions to the format. So if it uses an odd frame interleave, has copyright bits, is encrypted, has additional meta-streams or whatever, you cannot use that in AE. Similar to the previous, simply convert it in whatever tool you think gets the job done and/or what the online store you may have downloaded it from advises to generate a personal backup audio CD.

    Use whatever you feel like. VirtualDub, SUPER©, VLC mod, MPEG Streamclip and so on are all free. On of them is definitely going to be able to generate either a "clean" uncompressed AVI or Image Sequence plus an audio file for MP3s, simply use WinAmp. There's a million plugins for it and likewise one of them is bound to provide the exact combination you need to properly decode your files to a WAV file for use in AE.

    You have to think of the file extension, such as AVI, as simply being a
    wrapper. Inside that wrapper, there could be a fair variety of different
    flavors of gum.

    Lets say that you also have specific taste buds for specific flavors.
    Every time a new flavor comes along, you have to get some new taste buds
    installed in order to taste it.

    From your posts, your on the lower end of the learning curve on the
    video editing subject. AE however has a pretty steep learning curve
    because there are such a huge number of properties of that can be
    tweaked altered on any piece of video.

    If you are committed to learning AE, you start to gather and work
    through tutorials. The books by the Meyers are very good, but may be a
    little too advanced for someone just starting out.

    For your particular piece of footage, Virtual Dub was mentioned. With
    it, you can export the audio out into a standard PCM Wav file. I believe
    you can find a number of step by step how too guides on using virtual
    dub around the web. Searching them out will get you going on virtualdub
    quickly which is as close to a 'must have' tool for general video work
    as there is.

    Love the analogy! Hope you don't mind if I use it sometime.

    Your post is a year old, but I'm having the same issue - if I can return production premium, I will. I have never dealt with a bigger pile of garbage software than PP CS4. Premiere is dysfunctional and neutered, Encore doesnt work, Bridge doesnt work, PS has lost its web gallery, and now I find out the one program I actually liked in demos, AE is also ruined by some inane stupidity, like non-obvious audio controls. I have to RAM preview this thing everytime? Why doesnt it stay rendered? Why is fifteen seconds of a composition too much for this program to handle with its audio just sitting there. WHy do I have to press 0 on the numberpad and then space bar to preview audio and video together when that is so basic to editing? Who is responsible for this abomination....?

    First of all, if you want longer ram previews you just need more ram, or you can lower the preview quality to quarter. You can also ask the preview to skip some frames so you'll get even longer preview.

     

    By reduce from full res to half res, you will have 4 times longer previews, and 16 times longer preview if you are on quarter resolution.

    Previewing with 0 on the keypad will preview Sound and Video, so no need to use the spacebar.

     

    AE is not an NLE, and is clearly not optimised to do editing. AE is a post production tools and it has been designed to produce higher quality render over faster/longer previewing. That's why you cannot preview as in Premier Pro, Vegas of Final Cut. For each frame, AE decompress the full uncompressed version in ram, then apply all the effects and then render it with other layers according to your comp settings, whereas NLE will use optimised routines to preview video and won't uncompress everyframe like AE.

    Hi friend,

     

    I somehow manage to import and play the mp3 file in AE but still I am fighting with the avi files as they get imported in AE but unfortunately without any audio. If I run the same avi file with someother software it works perfectly fine. With yours and others replies I am getting that the avi video should have right codecs to play in AE but my question is what are the right codecs?? How do you define a clean avi video?? Please help!!

     

    Regards

    Ankit,

     

    You say that there is no audio. How are you determining this? How are you attempting to play audio? See these FAQ entries:

    "FAQ: How can I play or preview sound (audio)?"

    "FAQ: Why is there no sound (audio) in my output file?"
