Incorrect Audio Waveforms

[J_Pisciotta]

I'm having an issue with audio waveforms not displaying correctly in my timeline. I'm using Premiere Pro 13.1.4 on Windows 10 Pro. Below are two images, the timeline before the cut and the timeline after a thru edit.

I've tried clearing Media Cache Files and Peak Files. I've ensure that Save .cfa and .pek media cache files next to original media files when possible is unchecked. I've also gone into the scratch disk and cleared the audio previews. All drives and software is up-to-date.

I've Rendered Audio, restarted my computer, even moved the raw footage to a different hard drive and started over. Problem still happens.

The audio is synced correctly and there are no playback issues but not having correct waveforms is making my work very difficult as I primary edit interviews and have deadlines coming in fast.

I'm also having issues with the waveforms not even appearing....

That is, when you make a cut, does the waveform change? Regarding that the waveform does not appear: how much do you have of RAM?

Send us your system specifications please.

Hi Byron!

Yes, the waveforms are correct until I make a cut (or thru edit for example), then they change and get crazy lol. I'm not sure if this is an important detail or not but I've only encountered this issue (so far) when working with multi-cam sequences.

Premiere Pro 13.1.4 (Build 2)

Windows 10 Pro

32 Gigs of Ram

GeForce GTX1080 graphics card

Realtek HD Audio - Driver 6.0.1.7727

Ok, the wave looks different, but what you hear is correct or is something else heard from what should be heard? Because in that case you should configure so that your Multicam only changes the video shot based on just one audio master because I think you are shooting out the audio and video at the same time, so the wave also changes just like what you hear in that wave.

Right, the waveforms go crazy and change to something random the moment I make a cut. My general workflow is:

Select all footage from the project bin -> Right click and select "create multi cam source sequence"

-

This is where I make the majority of my cuts, complete the color grading/audio treatment

-

Then I right click the multi cam source sequence in the project bin and select "new sequence from clip"

-

This final sequence is where I make all of my angle changes and minor cuts to remove filler words or make an angle change more smooth and that's when the waveforms go crazy.

Here are the multi cam settings that I'm currently using:

Try to do this by choosing synchronization with "In Points" instead of "Audio." Remember that in this way you must add a Mark In in each video that is part of the Multicam, in this case it is useful to have recorded with a clack of a clapperboard but if you did not do it does not matter, take a visual reference and add a Mark In at that same point to all the videos.

Okay awesome! I'll give that a try on the next few projects and see if that helps

FWIW: I tried a multicam sequence and making a thru-edit, and I didn't see the waveform change. PP 13.1.4 (Win)

Unfortunately it doesn't happen every time... which probably makes it harder to troubleshoot.

I've tried everything I can think of, even had Adobe support control my desktop remotely and try to troubleshoot. Still no luck.

It's frustrating trying to edit video w/ out accurate waveforms. This'll be a long week for sure

If you get time and are really interested in trying stuff you can get yourself a small ssd swap it in as your c: drive (so you don't change your real/current c: drive) and install a fresh Windows then PP and see if it still happens. If so, you know it's your Windows causing the problem. Once you establish PP runs you can install other things and keep an eye on it, until you're mostly setup. If you get thru all that, it's probably some setting or driver somewhere causing the issue.

Once doing that some years ago, I couldn't duplicate the problem, then I installed something I didn't consider to be part of the problem - but happened to start the problem software and then the problem was there. So, I figured out by chance what had caused it.

I install very little software from the motherboard manufacturer. For the most part only items that appear in Device Manager without a driver after I've installed Windows. I see you have a 'realtek' driver... stuff like that.
