CC 2014 P2 audio problem

[Brian Prairie]

I just started having this problem with P2 footage too. I spent 2 hours on the phone with Adobe and still no answers. What is really troubling is that even when converting in AME the audio is dropped.
I opened the footage in CS6 and voila no problems. The audio and video is all there. Any update on what is going on with this issue?

Hi Brian,

As noted above we believe we identified the issue and placed a potential fix in the upcoming release. There are times when a fix addresses some users but not others so please give the new build a try when it comes out and let us know how it goes.

Thanks,

Having the same Issue plus some audio glitches in playback of the export

Well this response is a little frustrating.
I have found a work around but at the cost of losing 2 days of work. What if I didn’t find a work around? Do I tell my clients that I need to wait to finish their project till Adobe fixes the bugs in their software? Why am I paying monthly for a software I’m now uncertain of?
I love all things Adobe and haven’t had any problems for years. I’m feeling a little abandoned by the lack of concern with this response.

Hi Brian and all,

Sorry again for the frustration and time this has caused. A co-worker of mine did a bit more investigation and was able to isolate two related scenarios that led to a condition similar if not identical to what was reported.

Scenario A: Clip was touched by 7.x
Import a spanned P2 clip (AVC-I or DVCPRO) into CC7.x.
Insert a clip marker or revise any XMP metadata. (This results in an XMP file being written to the CLIP folder under CONTENT.)
Import the same P2 clip into CC2014.x.

Scenario B: Clip has an XMP file but no media cache files (specifically the .pek files)
Import a spanned P2 clip without an XMP file into CC2014.x
Insert a clip marker or revise any XMP metadata.
Save and close the project.
Clear the media cache files
Either reload the same project, or create a new one and import the same spanned P2 clip.

In both of these scenarios, we observed two issues:
A) the audio waveform is incomplete
B) no audio plays for the segment of the clip without a waveform.

In our testing, closing and reloading the project fixed the issue with the missing audio at the end of the clip. However, the waveform remained incomplete.
A workaround to get the full waveform is to delete the XMP file and the .pek files for the affected clips. Be aware that clearing the XMP will erase all markers and other metadata that is saved to the XMP file.

Just to emphasize, the issues we identified are limited to P2 clips that span two or more MXF files in CONTENT/VIDEO.

Please let us know if neither of the scenarios above apply in your case, if complete audio isn’t restored by closing & reloading the project, or if deleting the XMP and .pek files does not yield a complete audio waveform.

Thank you Peter for responding.
Scenario B was happening to me but clearing the cache and restarting the program didn’t work. It either worked for a bit and stopped working or didn’t work at all.

The deleting of the the XMP files and .pek files did work. However, upon testing this work around, I loaded some footage into Prelude and I got a little click happy and loaded a clip before it generated the peak file. Voila, no audio waveform again but the audio was playing. I also tested this in Premiere and found it to be the same. Once I closed the programs and reopened them, all was working once again.

Another thing I noticed
I was just testing your workaround. I loaded the problematic files and it worked. As another test, I then deleted those files and reloaded them. To my surprise, no waveform again and no audio. I quit Premiere and then started it up again and then loaded the project with the problematic clips. Waveforms and audio are back.

You are exactly right about the P2 clips spanning 2 or more MXF files. Those were the only affected files.

I wanted to share these scenarios with you and anyone else having these problems in hopes to fix this bug.

Thanks again for the workaround.

I recently got a new camera and when I used the external microphone plugged directly into my camera. I had the same audio problems downloading into Prelude 4 minutes in then nothing. It ingested into FCP correctly. Later recordings I used the internal microphone no problem. Is the problem fixed?

I still consistanly have this problem with my mxf files from my fs700. I’m on the most recent version of CC 2015.

I have chunks of audio missing, audio from other clips on the wrong clip, and sections of audio looping thoughout the clip.

I though this bug had been addressed, but I see no change in the issue.

Currently trying your work around, but hell, this has been a known issue for years!

Please help.

I have this issue with current QT h264 proxies rendered from REDCINE-X Pro.
Originally RED files with WAV attached via TC sync.
The editor swears the audio was intact during import and rough cut but every time we open/share a project audio clips look blank and missing at times.
Its all over the place wit this issues and we cant pinpoint it.
The odd part is when we exported to AAF the files are viewable/audible in Pro Tools.
Weird stuff from Premiere Pro CC 2014.
