Why am I getting an audio phase effect from my clip?

Hi,

I have a new .m2ts clip which I have brought into a new project in my latest VPx.

It is giving me a phase effect on the audio and I cannot get rid of it.

It sounds a bit like a jet plane above you.

I have tried other clips who also are affected.

I brought it into my new MEP and it wasn't there as it wasn't in my PowerDirector either.

Any help please.

I will mention after Activating VPx I also activated all the freebies that came with it however it seems none are active so I don't think they are the probloem altho' I am not sure.

Thanks

Hi,

It would be helpful if you could upload a sample of a clip so that we can get an idea of what you are hearing. Perhaps to dropbox so that it could be downloaded in it's original form.

Hi,

Thanks for the reply.

This is the dropbox link to a sample of the m2ts file with the weird sound.

Then again maybe it does not have that effect because when I load it into MEP, PowerDirector or Video Pro x4, it does not have it.

Hi,

I downloaded your file and played it first in Windows media player in Win 10. It sounded perfectly normal, allowing for the theatre echo and the limiting on the video mic. I then tried loading it into VPX and it sounded identical, so there is no problem with the file.

You say that other software plays the file with no problem, so are you using the other software on the same PC with the same audio monitoring?

Like Roger, I played the file in VPX and heard no phasing. I did hear rather a lot of distortion, due to overload of the camera mic, but certainly no other problem.

No problem with playback here either - apart from some clipping distortion of the audio already mentioned by Jeff.

What version number is your installed VPX - see under Help, About . . . ?

What you are experiencing would suggest you are hearing audio feedback when VPX is active, do you hear the 'jet plane above you' if you use headphones?

If you are using a laptop, or your PC has a microphone connected, check that the microphone is muted, not selected as a recording device in VPX and your sound cards settings for 'hear what you record', if any, are turned off.

Many thanks guys for your time and help.

I cold booted the machine this morning and the program gave a panel saying your installation extras were ready to download. I had already installed those yesterday and checked to see if they were in fact downloaded and they were there alright, so I chose 'Later'.

The program then froze so I checked TaskManager in Win 10 Pro x64 1709.
Magix Pro x (3) 400
Magix Pro x 395
MagixOfaHelper 2.9
Bridge 32_v103 (32 bit)

I Terminated it there.

Pulled the program up again, same panel, chose 'Later' again, but the program was fine, not stuck.

It is version 15.0.4.176 (UDP3) VG 8429KA1

Imported the same clip in and it was clear of that sound !

Really strange because yes I played it in those other programs on the same box with everything the same normal settings and it was fine, but even though I rebooted, opened and closed VPx a few times I couldn't get rid of the noise in all clips I brought it.

Anyways sounds fine now except as you say the distortion, too close to speakers etc which we knew was there.

Hopefully the gremlin has departed!

Thanks guys again

Magix is the maker of the program not the name - can you please use the correct name for the program you are using, the full name is under Help, About. . . , from the version number you are using Video Pro X.

. . . . The program then froze so I checked TaskManager in Win 10 Pro x64 1709.
Magix Pro x (3) 400
Magix Pro x 395
MagixOfaHelper 2.9
Bridge 32_v103 (32 bit) . . . .

Do you mean there are multiple entries for the items above where I have only the single entries for Video Pro X and MagixOfaHelper as shown below

and under processes

If not what do the numbers represent?

If they are multiple entries, then this means either the program has not been shut down or not shutting down correctly and has left multiple instances running which could be the cause of the sound issue.

Yes I am aware Magix is the corporate name.

Those 3 entries are in Task manager Processes (See image) as is Magix Network Sync as well as Magic PC Check & Tuning 2018 Autopilot (32 bit) and there is also MagixOfa_x64.exe in Task Manager Details and also Magix Network sync in Task Manager Startup.

Those numbers must have been the Memory use at the time.
