Z280 Proxy file, audio is distorted at DVinfo.net

Anthony McErlean · April 10th, 2022, 11:03 AM

Hi all, I just used my Z280 for the first time yesterday at a wedding and decided to also record proxy files as well.

The picture and audio from my SXS cards were perfect but noticed when I brought the proxy files into the timeline, the audio from the proxy files are distorted, wonder why?

Proxy setting was 1920x1080 9 Mbps Audio was CH1/CH2.

Any thoughts.Thanks.

The codec could be the problem. Post the file's MediaInfo so we may see the file's pertinent attributes.
If you do not have MediaInfo already: https://mediaarea.net/en/MediaInfo

Or post a file in Dropbox, We Transfer, GoogleDrive, or other cloud site.

OK Rick, link sent :) Hopefully is what you need.

Hi Anthony, the file does not sound like a good recording to begin with.. (mic placement and such), but the file's attributes and waveform look OK (not clipped or other tell-tale visual observation). If you can post the non-proxy audio file, I can compare.
Your player may not have the same AC3 codec as the cam (or whatever) it was encoded by. Try converting it to a garden variety PCM file <.wav>. There is an online transcoder ink below if you cannot transcode on your computer.

Thats a screen shot of the original file Rick

OK Rick, I will send a few seconds of the original, thanks.

Hi Anthony,
The 'original' file does sound better, but it not the same segment.
Is AC3 the audio format that the camera encoded, or is it just the format you exported as? The attributes of the files you posted are basically the same..

In any case, you could use the original audio tracks with the proxy video file. Most NLEs support adding and/or replacing files and timeline clips.

.

Yes, I exported from the timeline as AC3

I should have sent you the same segment, my bad :)

I don't understand why the proxy sound is so bad.

Thank you Rick for taking the time, very kind of you.

Rick Reineke · April 12th, 2022, 12:10 PM

Run MediaInfo, and post the attributes of the original and proxy files from the camera. Your exported files do not reveal a cause.

Anthony McErlean · April 12th, 2022, 01:41 PM

Ok, will do. Thanks.
