    head of audio clip doesn't get played... and in export too.

    So this year we've been noticing that occasionally the head of an incoming audio clip doesn't play- misses the first few frames. This is just at the start of playback.  Now I found it happened in a quicktime export. That's concerning. Anyone else?

    Re: head of audio clip doesn't get played... and in export too.

    This bug was logged as MCCET-3367 back in November 2019.

    I thought it had been fixed but I also experienced it recently with v2019.12. It's more intermittent now from my personal experience, but not reassuring.

    My workaround has been to splice in a muted audio clip before the first truncated audio clip.

    jd....

    I looked up the bug and Ryan did report this however they could not reproduce it and reached out to you under case # 03808778 but didnt get a response at all.

    what was asked is as follows:

    What type/resolution of source media is being used?

    When you say add 'VO ' to A1 in the steps to reproduce - are you suggesting that the audio on V1 has to be created via the punch-in tool/how is it different from the audio you're adding to A1-4?

    Please also provide screenshots of your export settings and/or a blackbox (simple QT movie export / MXF export with a regular clip of V1A1-4 does not reproduce this issue).

    Can you do that please?

    Hi Marianna,

    The last email I received from Ryan in tech support was on November 11th when he quoted the bug number. Prior to that, on October 24th, he wrote me stating that he HAD reproduced the issue. 

    My outputs consist of short 1080i TV spots, usually between 30 and 50 seconds long.

    The audio media being truncated is typically a mono broadcast WAVE send by our VO artist. I edit to A1, but I don't think the audio track matters in this case. The video media is usually DNxHD 145 MXF or ProRes 422 HQ, but the associated audio isn't usually affected. 

    In my case, playback within MC sounds fine, but exporting (to OP1a MXF or Quicktime DNxHD 145), or doing an audio mixdown resulted in consistantly truncated audio for the affected sequence. This issue does not affect every sequence or project, though but those that truncated did so consistantly on both Windows 10 HP Z840s and a 2017 iMac Pro.

    For me, this issue began with v2019.9. Rolling back MC to v2019.7 and re-exporting solved the issue immediately.

    Re: head of audio clip doesn't get played... and in export too.

    JD... 

    I just asked that Ryan re-open the case.  GRRR not happy that a case with a bug associated was closed.  I have added a case for Brian as well.

    My apologies and I am glad you posted or I wouldnt have known.

    Im on it

    Re: head of audio clip doesn't get played... and in export too.

    Thank you, Marianna,

    I got a support email from David (Case : 03808778), but when I tried to reply to it, I got an automated message:

     

    "Closed cases cannot be updated or reopened.

    Please login to the selfservice portal at http://csportal.avid.com to create a case"

     

    How should I proceed?
