Investigating deaper to identify when the bugs appear, i found that it is essentially when i try to adjust the audio level on the sound track.
When i move up or down the sound level on a particular scene or when i try to produce a ramp up or down on the sound track
This problème does not exist wen using premiere element eleven
Have you ensured you have all of the latest Windows 10 updates?
When you add your video to your timeline in Expert view, do you see a yellow-orange line along the top of the timeline above your clip? This could indicate a problem with the program optimizing to your video.
What model of camcorder is your video coming from and what format is it?
As i told you in a previous message i have made some progress . It seems that the problem is linked to audio parameters (bugs occurs only when i try to adjust the sound)
Having started a project with elements premiere 11 and loaded late the project in element 14 , i have no problem of tha kind ??
Probably a problem off parameters but where and how i can adjust them ??? I cannot see the what is changed betwwen the two version ???
I might better be able to help you if you'd answer my questions.
