Bad Audio After Editing

I have used this software to 20 or so videos with no problem. suddenly the last 2 have turned good clean mic audio into cracking and popping noises. i havent changed anything since my last good video and i have no idea. i would like to eventually purchase this software but i love the interface but i cant if it doesnt work. please help if you can.

in the media page, does the audio play correctly?

No it does not

sounds like its a mismatch of audio interface Hz - on your computer make sure your recording interface is set to 48000hz, and playback is set to 48000hz. see if that helps.

I had exactly the same thing after my mixpre6 (also my audio interface) reset and had the record set to 44000hz.

Both are already at 48000

I'm looking at the meta data to see what the project is in right? Mic (RODE NT1) is recording in 2 channel, 24 bit, 48000 Hz. Attached to a Focusrite Scarlett Solo gen 2. Recording software OBS. everything is fine up until it goes into Davinci which says its also 48000 Hz.

have you checked that the focusrite is set to 48000 for record and playback? I never used one so know nothing of them, but on my mixpre6 it is possible to have record set to 44 and play set to 48 which even if not recording can throw audio into a spin.

Both are set to 48k

No it does not

If you do a fresh project and import only that clip, does the audio in the media pool play correctly then?

That sounds like a clocking issue with your narration. Possibly a problem with your Focusrite or its' driver. Also is OBS set to Constant Frame Rate and Bit Rate?

Everything is set up to work and has worked in the past

As nothing has changed I would have to suspect a problem with your Focusrite interface.

Should I try to update or reinstall the drivers?

Yes, that would be a good place to start. Even re-installing the current driver if no updates are available can cure problems.

I'll give it a shot

Another thing to try is recording directly from your interface into Resolve and not using OBS. Also, make sure that Windows audio is set to 48k.

I reinstalled the driver with no luck

can you load a 10 second clip in a dropbox?

my best guess is a variable/different frame rate somewhere.

I couldn't figure out how to just put up a 10 second clip so I'll just provide the raw footage and edited footage.

I downloaded the clip. Looks like a variable frame rate issue. Quicktime player frame rate changes constantly on playback.

But the video in the media pool starts messed up.

variable frame rate. Both clips are a different length. Bring them back into resolve, put one on top of the other on a timeline and line up frame to frame at one point, its different everywhere else in the timeline.

audio frames are being dropped/missed to keep up with changing video frame rate

How exactly do I do that? I'm very new to editing and the instructions went right over my head

I'm just so confused that everything worked great one day then the next my audio is messed up. Without changing any settings

Also the sound is messed up in the media pool how would changing it in editing do anything?

Here is something to check. Download and install the free Mediainfo app. Open, and in the FILE tab open one of the video clips. In the VIEW tab select TEXT. Check what it says about Frame Rate. Do the same for the other video clip. You want them both to say CONSTANT. If one says VARIABLE, that is the probable cause of your problem. See my example below.

Ok I'll give it a shot. What do I change if they're not constant?

The video says constant but the audio 1 (game audio) says variable. Audio 2 (Mic) says constant

If one or the other shows Variable frame rate, whatever you use to capture the video needs, if it's capable, to be set to Constant frame rate. An example of this would be something like OBS which can do both. Smartphones tend to use only Variable frame rate.

Ah ok let me check OBS

It might be an idea to go back a bit. How do you capture the game footage and your piece to camera?

I cant seem to find the option in OBS

Can't help you there as I don't use it.

so the issue is most likely that obs is using a variable bitrate for the game audio which is messing up my constant mic audio?

That is a distinct possibility. You said it used to work so something somewhere has changed. Maybe look at some previous footage from a video that worked with Mediainfo to see if the parameters are different.

wish i still had them but thanks a bunch for the help. I'll continue this on the OBS help thread to see if they know how to fix it.

i managed to find an old video and everything is set to constant! so that must be the issue! you're a great help.

Glad we seem to have got to the possible cause. Hope your edits go smoothly from now on.

I figured out how to make everything constant and i am still having the same issue with Davinci unfortunately

i also just grabbed an old video that originally worked fine and now Davinci also does the same thing as the newer videos so I've definitely isolated the problem to Davinci

Brett, I just downloaded your video file and opened it in Resolve. It plays fine. I notice you have the game audio on track 1 and your narration on track 2. Without the live video of you your audio on track 2 has no artifacts. So, if you can provide a short section of your to camera video, I will test that.

Hi guys.
I have been having this exact problem myself for aboute a month now, or two. It has been eating @ me, and making my editing very difficult.
I'm basicly using the same setup as you and running 3 auditracks.
To be honest, it has not been fun at all. I Have tested EVERY possible combonation of both OBS, windows and davivci.

But I think I have found the answer to this problem. I have the GTX1060 6gb and therefore I have used the NVENCH H.264 encoder. Because that is what you are suposed to do whith a Nvidia GPU.
I just switched to x264, an by god. It made a HUGE difference. it's not perfect att all. But with a bit tweeking and twerking I think I can get it.

As I think back, there was a huge driver update throug Nvidia Experience aboute the time when I first started noticing this problem.

What is happening, and why, IDK. But maby you learned gentleman could elaborate?

I bet mothers keyboard, that if you change your encoder, your microphone track will sound mutch better.

PS:
After sitting here all night. I have a solution for best possible audio. The problem IS a missmatch in frames. OBS records only in Variable Frame Rate. The missmatch is exstreamly small, so small that most programs don't actually recognize it. But it is there.

After running my recordings throug HandBrake in constant frames, the audio was perfect.

No problem att all. Crisp clear like a chill desember morning.

Even in NVECH Codec.
It is unfortunate that this is necessary. But I have to use OBS, And I love using Davinci Resolve. So the tradeoff is OK in my book. it is only 1% of my total editing time annyways.

Hey there,

I have exactly the same problem. I'm running the Focusrite Scarlett 6i6 and also a GTX 1060 6GB in my System. And (nearly) every time I try to comment some of my recorded videos of my Panasonic GH5 I get this stuttering sound.

Here is an short example recording together with the diagnostic logs:
https://www.dropbox.com/sh/50v35bc8fowe ... RmVya?dl=0
Notice the stuttering after I already stopped talking.

The interface is also running on 48KHz. I tried many different buffer sizes as well, nothing helped to far.

The issue also occurs when there's no video running at all, that is I just record some audio. I always have to switch to Cubase to record my audio and import it to Resolve at later time. That works always as intended, absolutely no matter how the interface is configured but that also results in a far slower workflow and Resolve (at least theoretically) has exact the possibilities that I need. I also had this problem with the last ~10 versions of Resolve Studio 15. But I also have to say that there were some few, very few cases where recording a short, clean piece of audio was possible (until it was bad again seconds later), but I guess that was more a random effect.

As you mentioned handbrake: that really can't be the solution to transcode every recording first before doing the ADR recording. Then it would be way faster doing the recording in another software. Any other helpful solutions in the meantime? Maybe a good hint directly from BlackMagic?

Many thanks in advance!
