How do you handle audio ticks due to rough edit boundaries?

[Noah Kadner]

Hey Ty-

FCPX audio containers have fade handles at the edges. You can also keyframe audio in the inspector or on a clip. That said- ticks I’m assuming you mean audible pops shouldn’t happen if the sampling rates are in order. Perhaps you could describe the situation in more depth?

I use the fade handles for a quick fix otherwise I use CTRL-S to reveal the audio, zoom in as much as needed and massage the edit a little. Usually only takes a few seconds to sort out.

Hi Noah,

They are zero crossover errors from two dissimilar sections of audio bumping up against each other. I tried the Control S suggestion. That worked in one situation but caused 2 clicks in the other.

It’s amazing zero-crossing edits aren’t standard. In the 90s when we used a Sonic Solutions DAW every edit was made at a zero point. You get clicks because you have a step-function where one side of the edit is low energy and the other is higher. The sudden transition manifests as a click. What I do to eliminate this kind of click is extend the audio on both sides of the edit and apply fades to each. It’s a bit of a pain, but that will eliminate zero crossing clicks.

Then there’s Alex4Ds Sound Only transition here.

Hmm I’d take a good at the sources- haven’t hit this in years of FCPX editing. Or maybe you could provide an audible example for those of us not quite so attuned as you are.

Where I notice it happening a lot in dialog is where one take has a strong low frequency rumble (which in most cases you’d never hear without a sub woof) and it cuts to a take where the rumble is gone. If no SFX or music is there to mask it, you’ll hear a click. You can see the low freq rumble on meters. Another way to lessen this kind of click is apply a hi-pass filter that takes out the very low frequencies.

At the end of the day audio editing isn’t FCPX’s strong suit. Sometimes there’s good reason to send the audio to an external app for finishing.

But I can say that I’ve been exclusively editing in FCPX since the day it was released and I could count on one hand the times I had a zero crossing issue, and I can’t remember any time I couldn’t massage it away by tweaking the edit at the sub-frame level.

Hello John,

Yes, I know about Zero Crossover errors. I was just expecting a less kludgey fix.

I got rid of them, but sheeseh!

Good to see you out here.

Regards,

Ty

Jeff,

Thanks, how do you zoom to the sample level without getting bloody nose?

Will the zoom bar take you that close?

Thanks,

Ty

I usually use Cmd-= and Cmd– to quickly zoom in and out; you can zoom in super close and trim/adjust the audio levels easily, then zoom back out and continue with your edit. The audio fade handles are super handy, and you can also keyframe if needed by Opt-clicking on the volume line in the clip.
