Audio not working with FX6 .MXF files

PostWed May 24, 2023 11:25 am

Hi Everybody,

I am importing UHD FX6 - MXF. files in the timeline.
And together with the bug that audiowave forms are not showing up, (solution: give it some time to load them in)
I do get this strange bug that I play the timeline but I don't hear anything... I see the waveforms showing but, the mixer/meters are not working too.

So I basicly have to manualy pause the timeline and when I do continue with playing the audio sometimes gets back.
Till the moment I scroll, or switch pages, or land my indicator somewhere else in the timeline.

So I have to do this everytime, pausing and playing to sometimes out of the blue get the audio working?

Does anybody have a solution for it, working with MXF files?
Or some setting to render the audio? I have a feeling that might be the solution to all...

Let me know.

Can you share a clip for testing?

There have been a number of reports of failed audio playback with .mfx files when they're on the timeline (with some reports that they'll play without issue in the media pool), both Sony FX6 and 9, as well as some Canons.

I don't think it was ever solved. You could try rewrapping or recoding the audio to .wav. If you're not using Studio, that might also be at issue.

Aah so I am not the only one, was thinking about it haha.
Any news of BM if they gonna solve it in a new patch? Or busy with it to fix it?

Is there a simple way to do that? Would you do it like, just cut the audio and seperatly export it to .wav and re-attach it to the main video file??

Sorry Tiemen, I meant share one of the camera clips. Let us play with it, see what happens.

The simple way is google "Shutter Encoder" (or similar utility) and download it. You'd want the "replace audio" option, and for the PCM conversion select whatever the original bit and sample rate is. How well it works with multi-tracks I don't know.

Thanks for this option! I will give it a try. I have been able to edit some of the multi clip outputs already, but I have a view more. But I'll give this a try, because it could end up saving me so much time. So thanks

Got it.

If you own the camera, you could shoot some innocuous footage. Let us take a look at that.
