In this sequence  voices audio are deleted or "parasited"  ... But  in original  file ,and youtube pc version work perfectly .

There's a good chance that your dialogue tracks are stereo but with left and right out of phase. One fix is to add the fill left with right audio effect to the faulty clips or track. If this is the problem it is most likely caused by using an XLR balanced mic with a 3.5mm stereo camera input.

J'ai écrasé la piste droite avec la piste gauche, Miracle, le problème a disparu. 

Probleme résolu, merci beaucoup .
