Enabling the option `Play every frame` normalizes this "2fps-playback"
of 1920*1080
avc/pcm.mov files.

But anyway this codec is not comfortable for editing. It is expedient
to re-encode
it in DNxHD or to mjpeg.mov
-
If I want to do video for youtube, you should know that youtube  *always*
re-encodes *any* video. This means loss of quality.
 So selection of  optimal parameters of encoding for youtube - this is not a
trivial task.
The best way  - to render to yuv4mpeg master-file and then using  CL for
encoding.
