Default Video Engine can't launch

I am troubled now cannot play a video truck without being able to load video engine.
The progress bar which I am going to load appears and becomes 100% in more than one minute when I turn on the check box of the video engine, but does not start even if then it passes for several minutes.
And the following alerts appeared after around ten minutes.
"Kernel extension is not from an Identified developer
The kenel extension at "/System/Library/Extensions/DeckLinkFrameBufferDriver.kext" is not from an
identified developer but will still be loaded.
Please contact the kernel extension vendor for updated software"
Is this driver made in Avid?
Answer myself. It's a Black Magic's driver.
I do not remember that I installed the driver, but QuickTime video format is DV.
So the session that imported the video truck of this format may require Black Magic.

Default Re: Video Engine can't launch

I solved a Video Engine trouble myself.
I could not find a reason why video engine did not start.
However I found the method to run at last.
Therefore I use an Activity Monitor.
At first Pro Tools started, Activity Monitor shows Avid QuickTime Server does not work by red letter.
To force quit Avid QuickTime Server, double click the red letter and open dialog.
After quit the process of Avid QuickTime Server, restart the Pro Tools, not restart a OS.
That' all.
After the quit the process of Avid QuickTime Server have been freezed one time, Pro Tools can run Video Engine.
