[BUG] audio not synchronized after cutting videos

[Selur]

Is this the wrong file?
I need the source to properly reproduce the issue.
The file you linked to does have chapter markings at:

• 00:00:00
  
• 00:00:02
  
• 00:00:05
  
• 00:00:07
  

and is alread HEVC created by Hybrid. (There are no key frames at the chapter markings.)
The chapter file you liked to has chapters at:

• 00:00:00.000
  
• 00:08:08.000
  
• 00:12:00.000
  
• 00:15:08.000
  
• 00:19:20.000
  

Since:
a. your steps include no adding chapters
b. the clip is only 13 seconds long
c. the clip only has key frames at frame 0 and 300
I'm a bit confused.

-> Properly explain this please.
