Audio Keyframes in FCP
Hi guys, I’m working on FCP5 on a G5, here’s an audio keyframing question.
Hopefully I can phrase this in a way that makes sense, but I was cutting earlier, and needed to do an audio fade using the pen tool. However, I couldn’t get the keyframes to transition linearly, as opposed to the arcing or curving line between the keyframes, so I had to add a bunch of extra keyframes in order to get the audio effect to be the way I wanted it. Is there a way to get a straight transition between two keyframes?
For that matter, is there a way to open the audio transition in the source viewer so I can change this stuff as well?
Thanks,
Oliver -

Yes and yes.
It’s all in the manuals, sorry to say, you’ll need to hit the index or the online search.
Linear ramps are disabled by default since audio energy is not linear.

This is my standard sigfile so do not take it personally: “For crying out loud, read the freakin’ manual.”

Yes, you just double click on the audio clip just as you would on a video clip and it will open in the viewer. You could also bring up the mixer window and make sure the record keyframes box in the top right is checked. Then play the clip and grab the fader with the mouse and drag it down at whatever speed you like and it will create the necessary keyframes for you. -
I’ve also longed for linear ramps and have found nothing about it in the manual.
Bogiesan- your response was a bit short in my opinion. There is an option for linear audio transitions but I have never heard of linear ramps for FCP. Please let us all know where this option is.

> Bogiesan- your response was a bit short in my opinion. There is an option for linear audio transitions but I have never heard of linear ramps for FCP. Please let us all know where this option is.< Yeah, that's me. Short. Short and RTFM. I cannot imagine what possible difference a linear ramp could make to the aural presentation. The old Media 100 displayed straight line ramps but the actual envelope was a curve. When you follow the curve on a scope, the aural impression is actually linear because of the logarithmic dB scale. So, the result of a straight line envelope would be an aural curve? bogiesan This is my standard sigfile so do not take it personally: “For crying out loud, read the freakin’ manual.”

The Original posters point is that often FCP cuts the audio too fast at the tail. I find this particularly annonying when ending a long form sequence and would like to fade out the music track nice and long. But FCPs curve cuts the long fade too quickly and one must zoom in and add more nodes- PITA!
Media 100 was different- it was linear.
So how do we turn the curves off? Like I said earlier- I didn’t think it was possible.

Well there are small things like SPL–Sound Pressure Level–, dBu, dB and VU. Here are a couple of sound links:

And if you have a wheel mouse you and use the wheel like a fader while hovering over the the mixer fader GUI.

I need the same thing all the time. I just make a cut and use the 0db cross fade transition. That seems to give you a linear fade.
Thanks for all the constructive responses to this perfectly valid question. No thanks to the pompous ones, you know who you are.
