Zenny, I reproduced the bug using these effects. For me, Blue Screen alone
does not repr

Finally I figured out that three effects in combo are generating the
jitter in multi-threaded rendering:
Blue Screen
KeySpillMopup
Alpha Operations
Disabling them didn't produce any jitter as follows. Hope this helps.
//STARTING RENDERING: false , false , "/usr/bin/melt" ,

Hi again:
I disabled Blue Screen only and rendered, still the jitter existed.
Again I disabled keyspillmopup only. Both produced jitter.
I tried once again by disabling Blue Screen and Keyspillmopup, still
it produced jitter.
So It cannot be ruled out that the culprit is Blue Screen.
Seems like
Okay, here is an update:
The reason for jitter is the chroma key (blue screen) effect while
multi-threaded.
As you advised, I rendered with a single thread and also by disabling
effects one by one. Like you stated, when Chroma Key effect (Blue
Screen) is disabled, the jitter went away.
However,

Thanks Dan for such a wonderfully-written FAQ.
real_time=>0 worked like charm.
However there is no way KDE does multithreaded with real_time=>0
except creating the script and manually change the script.

Hi:
Trying to render both melt in command line as well as from kdenlive a
composite video with threads=4 with forced progressive. But it seems
it only uses only one CPU.
Is this a limitation of mlt that multi-threading is not possible with
composite video rendering? Thanks!
