Hello RadHom,
Welcome to the
AudioDirector forum
What you've observed is that, using the iZotope RX7 Declip VST in round tripping, the process inserts silence at the start of the clip (i.e. increases the total duration). Have I understood it correctly?
I don't have the VST plug-in you've referred to (iZotope RX7 Declip VST) & I don't typically use VSTs in round tripping between PDR & ADR, but in the tests I've just done with
other VSTs I haven't been able to replicate your issue.
In the tests mentioned above, I used a UHD (LPCM audio) clip with duration of 00:04:48:06. In every case, using a variey of VSTs in ADR, the returned WAV file was 00:04:48:06, with no inserted silence.
Perhaps, for testing purposes only, you could attach the VST here (.dll file) and members could investigate possible causes.
Also, could you post the properties of the video/audio clip you're using?
