[Kdenlive-devel] Audio sync issue

[el jefe delito]

Good day!

I'm running KDEnlive 0.9.4 on Debian Sid, editing MOV (mp4) files from my
Nikon 5100 DSLR camera.  When I render, regardless of the output format, I
get audio-sync issues; words don't quite match up with the mouth which
speaks them.

Is there anything I can do to prevent this?  should I create a bug report?

Thanks much for the software and hard work.
