    Trim audio without move keyframes

    Hi!

    I´m working in Xpress, Composer, Composer Meridien, Symphony and Symphony Nitris. Now I need to perform a action if it´s possible. I want to trim a audio track whith keyframes to perform the audio mix. Can I trim the track without move the keyframes.

    Sorry for my English. I´m spanish.

    Thanks a lot.

    I don't use audio keyframing, but with video keyframing, trimming a clip will cause the position of the keyframes to slide relative to the new length of the clip.  The only way to edit without altering keyframes is to lift or extract a section out of the front or back of the clip, instead of performing a trim.

    I assume that audio keyframing works the same way?

    Kevin:

    For video keyframing, if you promote the effect to advanced keyframing, right clicking on a keyframe within the advanced display will give you "fixed" or "elastic" options.

    Regarding the audio issue, no, I don't believe it's possible to slip - slide trim without the audio keyframes moving along with the trim.  I also believe you would not want them to anyway, as those keyframes still represent the various audio cue points for level changes, even after the trim.

    Instead of using 'Trim', try just using the 'Add edit' command to split the track, and then delete the bit you dont want.

    Unless perhaps you happen to be trimming a music track beneath dialogue that, for whatever reason, needs to be more or less locked. In this case, I can see how the ability to have keyframes hold in time against the level changes in things like dialogue pauses would be useful. Otherwise, there's always the old cut-and-dissolve approach.

    Re: Trim audio without move keyframes

    Adding a cut it is no a solution because audio keyframes are moved with the clip when I move it. I need to trim a audio track (a no-voice song) to make end the song with my sequence. If i do changes in my edit and i had yet the audio leveled I need to move the audio track without move keyframes. I do it in Sony Vegas Video but this was a software that can copy and paste "audio envelopes". I want to know if i can do simething like this in Avid.

    Converting videokeyframes in fixed is a very interesting feature that I don´t knew in Avid. Thanks. I´ll use it!Be sure.

     

    Thanks a lot again and sorry for my poor English!

    Re: Trim audio without move keyframes

    I fear you can't actually copy "audio envelopes" as you can do it in Sony Vegas. Yes, Sony Vegas has some very intersting features. I am currently "discovering" this software, some useful things may be introduced into the Avid world (which already exist in Vegas), for instance 5.1, or direct Blu Ray burning feature, etc...

    Re: Trim audio without move keyframes

    If you move the audio clip, any keyframed audio level changes will move with the clip -- this is usually desired.  However, you can move all of them them back into the sync that you orginally wanted by marking the keyframes in to out, hold down the ALT (is it the Apple key on a Mac?), cursor one of the keyframes and drag them back to where you wanted them relative to the video, or whatever sync you wanted.

    It's actually better than most, clear and polite. Don't worry!

    Here I guess the problem is different, in Vegas you can copy the audio envelope, that is to say you had keyframed music track in timeline, with many keyframes level control, you decide (the client wants you) to change this music : no problem, you change the music and apply the envelope, similar to copy without source for a title or an alpha channel still keyframed animation.

    Re: Trim audio without move keyframes

    Yeah, I actually have to correct myself in that the one cannot highlight and slip keyframed audio.  That only works for ganged level changes and/or deletion of the keyframes.

    Maybe we should move this thread to the wishlist forum.
