OK, what I'm going to say sounds totally daft, but please hold fast:
Scubbing with Contour Shuttle Pro (CSP) at the highest speed x20 freaks out both B321 and B353 and I get crashes and whiteouts. However I can Grab Cursor with Mouse and go even greater than x20 without issues. GO figure? So I have reproducible separation of issues. I needed to directly observe what is happening. And the only way I know how to do this is via M$ Task Manager. Well, viewing TM I can see TWO distinctly different Observations:
Observation 1: Mouse Scrubbing >x20 Power Usage goes VERY HIGH but within 2 seconds reverts to VERY LOW - Mouse Scrubbing Power Usage goes VERY HIGH but within 2 seconds REVERTS to VERY LOW. This indicates to me that there are VP process that have/are working as they should and close down so not to consume POWER. This is a good thing - yes?
Observation 2: CSP x20 Scrubbing, the Power Usage goes VERY HIGH however REMAINS very high. No matter how long I wait VP17 Power Usage will not revert to LOW. It's stuck VERY HIGH. Which, in turn indicates to me that there are still VP Processes still active and not closing down as they should. Then I come along and add FURTHER demands on VP, either by just clicking on another command or activating a further process, until I get crashes. This is a bad thing - yes?
Now, here's the REAL Kicker: None of the LOW/HIGH Power Usage issues are apprent in VP16. I can FULL Speed my CSP and Power Usage once I stopped scrubbing reverts to VERY LOW.
Conclusions:
A] As I said, I'm using B353 "with trepidation" and I have a Weather Eye on Power Usage in TM as this is the only indicator to me that there aren't any closing-down processes issues apparent.
B] None of this happens in VP16.
Whilst writing this I'm watching VP17 B353 Power Usage:
And from this VP Power Status "Very Low" I repeated my Crash Test Dummy process of NB ColorFast2 and HOS Render As Take and got this:
However, that VERY HIGH POWER USAGE reverted within 2 seconds to VERY LOW. And again, this in turn implies that ANY B353 Processes had been carefully closed down, thusly releasing and allowing further Commands/demands made by me.
I'd like your comments on my findings especially @VEGASDerek .
For the moment B353 is also Holding Fast!
