Hello world,
I have a problem with STP,2.2
I have a project 48 Hz to 24-bit stereo with various effects and music tracks Spech, All tracks (16 audio and video) and then go submix mix.
I set all levels on all tracks using keyframe and everything is ok due when I put it in playback and L ISTENING, But when I export the mix 48Hz in 24 bit format AIFF in some parts of the timeline controls the faders do not correspond to those I INPOST or in some cases does not export the clip mounted. I tried everything, The movements of the faders to rewrite , Deleting, Move track, But the problem is not resolved, Who can help me??
