BCC Mocha crashes with Avid on exit

Hello, I’ve noticed others with this issues but currently can’t solve the problem.

When using any BCC effect which has mocha tracking, opening the mocha interface is fine, tracking is fine saving is fine, but once I exit or try to export tracking data it crashes along with Avid.

However, when using a Sapphire effect to access and track in mocha I can exit the Mocha interface fine and return to Avid as normal.

BCC version is 11

Currently running HP Z840, with Nvidia M4000 (with Avid recommend driver 353.82), 32GB RAM, Windows 7, Avid 8.9.3. Also same result on similar workstation but running the latest Nvidia drivers and Avid 2018.5.

Hi Benjamin,

Thanks for letting us know about this. Are you using BCC 11.0.3, which is the most recent version on our website? If not I suggest downloading this free update to see if this resolves the issue.



In this situation, when mocha is crashing Avid on close, there are a few things you can do that should help matters. Note however that these will need to be in place the entire time in order for mocha not to crash, so when you open mocha and make these adjustments, even if you set everything up correctly, it will crash on Close at least one more time.

The primary things are that mocha’s interface needs to be entirely visible on a single monitor - That is, none of the interface can be off-screen, none of it can cross from one monitor to the other, and nothing can come up in front of the interface while it’s up, such as the Task Manager or an Email/Browser program.

With this, I recommend keeping the interface in a way where there’s at least 20-30 pixels on each side before it hits the edge of the monitor view. Along with that, if you bring the interface close to the top of the display, Windows will trigger the option to Maximize the window - If it does this, the problem will occur immediately, so you’ll want to make sure you avoid this at all cost.

Lastly, which monitor you choose to show mocha will play a factor, and it might not be quite so obvious. The primary thing that will need to be in place is that both the Effect Editor and the mocha interface need to be on your Primary monitor. Note that this is not necessarily the one with the Start menu; instead, if you go into the Display portion of your Control Panel, and then into Adjust Resolution, press the ‘Identify’ button and each number will show the number “1” or “2” - the one that shows “1” is the one that both the Effect Editor and mocha interface will need to be on.

Hope this helps.

Hi, Benjamin,

Can you confirm you are on the latest 11.0.3 update of Continuum? If you are on 11.0.3 and you still see this issue then I suggest contacting our technical support team directly so we can investigate further:
