audio keyframes- change curve to straight
Hi- help!
When I create a keyframe and drag it down, (say to fade out audio) it gives me a curve instead of a straight line. Try as I might I can’t figure out or find how to make it default to straight, or change the curve (apparently creating a bezier) to a straight or corner point. (I found “ctrl-click and choose Make Corner Point” but it’s not giving me that option.)
thanks,

The curve represents the math of the sound going down gradually:

Logarithmic. The software engineers apparently wanted the curve to be represented in the interface in a mathematically accurate way.
The way you perceive it is a straight line (linear) – full volume to silent. Has to do with the way we perceive things. F-Stops with their odd numbers – also caused by the way we perceive light, similar to sound, logarithmic, blah, blah, blah –

In the end listen to the fade and decide if is sounds good to you.
If it does not sound good or right to you:
Look up “record audio keyframes” in your manual and do the fade with the mixer letting FCP add keyframes for you. This way you can tweak the fade to sound just the way you want it to.
If you don’t want to crack the manual here is a link for you:
Alternatively add points manually in the timeline and tweak until it sounds right to you. Just ignore the way the curve is shaped and listen.
Best,

Very old thread to revive but anyway…
I’m sure it sounds better, but for my purposes i *need* a straight line and not a curve. Is there any way to change the curve to a straight line?
Many thanks,
Dan
