Duplicate first frame with low FPS override in RAW video
Created originally on Bitbucket by spccb
When using RAW video and set FPS override to a value <1.5fps, RAW video file extraction duplicate the first frame.
Frames sequence should be: 1-2-3-4-5-n
But frames sequence is: 1-2-1-3-1-4-1-n
Notes:
• With the same low FPS override, in regular h264 video mode there's no issue.
• Last summer I'v reported the same issue:

• The problem was solved in a1ex August builds (not in a.d. builds) and come back in a1ex builds:

Supposition: Maybe during the autoexec unification?
