Sometimes after I've edited an audio file in AudioDirector 7 and the WAV is send back to PD15, the audioclip is a bit shorter than the videoclip it belongs to, and also shorter than the original audioclip. Linking audio and video is no longer possible then. Any thoughts what might be the cause of this? ----------------------------------------------------------------------

Hello AdrieH,

Welcome to the AudioDirector forum smile

Your issue is concerning, & has been raised previously in the forums.

I've been attempting to replicate it here, but without luck. It appears that you're editing the audio part of a recorded video. Is that correct? Or was it a separate audio bed?

Could you please post all the relevant MediaInfo reports for your video clip(s), seaparate audio track (if applicable) & the WAV file returned from ADR after editing?

Hi PIX,

this is the medianfo from one of the original clips where it happens:

And this one is from the generated WAV-file:

General

Stream size : 2.98 MiB (100%)

I see now that the original AAC-audio stream also is shorter than the video file. Does that imply it's not a ADR problem?
Still, it's a strange thing that with some clips it's no problem, and with some other clips it is. Hope this helps a bit.
