Final cut pro adding popping to audio

Thank you! =) So in OBS we record in MKV, that way if there is a failure, you don't lose your whole video. Tonight I'll try to just directly record to MP4 and see if there is a difference though and report back. But, I thought these screenshots from OBS might help you see what I have to work with?

I posted up two videos that are easier to compare between.

With these videos too, I was intentionally making sure that even in OBS, that the voice and sounds do not go over -6db, as I thought that might be the case too after what you'd said.

This one is from OBS after it has been remuxed from an MKV to an MP4

This one is from FCP when we take that MP4 and put it into FCP

Nothing was touched. I can hear snaps and pops in the FCP version but not the OBS MP4 version.

Here is a screen of the max decibles reached during the entire short clip: -11

It's also very possible I'm going crazy and hearing things XD I certainly hope not! A friend told me they hear no difference, but I swear there are pops and snaps.

Just got ffmpeg downloaded. Don't really know how to use it. Can this remux an mkv to an mp4 for FPC? If so, I'll try that tonight when I record. I think I see how that works after watching a few videos.

As for the information you're asking for, I ran "ffmpeg -i fileName.mp4" and got this output for both TestForOBS.mp4:

and for TestForFCP.mp4

I hope those were the outputs you were looking for.

Thank you for helping =)

OH! And, for the variable frames bit of your response. I'm still learning a lot of this, but I was wondering if this might be where the problem is if there are variable frames?

I'll freely admit that I kind of just followed a few tutorials about how to set this up for recording on mac, and basically copy pasted these settings into OBS.

Ah hah, I think I see now what you were talking about. The frame rate is variable =(

Dang it =( That's a real bummer.

The OBS mp4 is created through OBS. From File > Remux Recordings

The FPC mp4 is created from the OBS mp4.

I haven't got the time right now but tonight I'll record from OBS as an MP4 and see what happens. It's just scary to do that for long play throughs because if it messes up, you lose everything.

I did try to remux an MKV from OBS using FFMPEG, to an MP4 and it appears to be a lot better, but there was still a pop or two when I was going through it.

So, maybe FFMPEG is my solution. D= Is there a remux program that has a GUI? Or must I do it through terminal? Is this the best option?

Just going to add this link in here because apparently this has been an issue in OBS for a while. =( But if it helps someone else with similar problems, then hooray.

Oh, I was just starting up a project to see what I was doing in FCP. These are the settings I use there.

Thanks for the reply. I went and checked, and the average is around -12, and sometimes reaches -6. At least according to Final Cut Pro.

oooo, and the bug report comments are interesting on this. https://obsproject.com/mantis/view.php?id=1115
