[ISSUE] Video Engine crashing in 6.5.3

Well it’s moody. Now It’s crashing constantly and I have no idea why. I have stripped the Quicktime Folder as suggested, part from the Blackmagic component.

Can SB give some kind of update on this please?

Hello to you all,

this issue seem to happen more often recently. We are still
investigating into this.
The only situation to reproduce this problem here inhouse is
having the “DVCPROHDMuxer.component” present - located
Drive / Library / QuickTime / DVCPROHDMuxer.component

When creating an Aggregate device (not even used in Nuendo)
makes this issue worse. Removing this component, solves this
here. Other than that we can´t reproduce this problem at all.
We aren´t still sure which application (tool) install`s that
component. If you could help in that regard, we´d appreciate it !

Please remove this component and report back the result for
your system. Thank you.

The situation of the videopreload, videooutput and videocode
process in the Mac “Activity Monitor” showing “not repsonding”
is not affecting the functionality and a different topic and is
almost fixed.

best wishes, Tino

Hi Tino

Thank you so much for responding. I appreciate the information.

I have pulled out many codecs this morning, including the DVCPROHDMuxer. I wonder, would you like me to put the others back in, APART FROM the DVDHDPROMuxer, as a test?



Hi Ben,
thank you for your quick reply. Yes, please put the other components back into the QuickTime folder apart
from the “DVCPROHDMuxer.component” and let us know if it´s working ok for you ? Thank you, cheers, Tino

Hi Tino, I pulled out the DVCPROHDMuxer like you directed me to in our emails. I’ve not had it crash since (about 2-3 weeks). I now believe the other problems I’ve been experiencing are not related to this.


Taking DVCPROHDMuxer.component out did the trick here and I have no crashes changing the sample rate frequency :slight_smile:, but I still having CPU spikes due the video component, even when I don’t have any video in the project. In fact, I’m working without it (taking it out from the components folder) any time that I don’t have to use video. The CPU spikes are really a deal breaker most of time. I’ve been working in a project that needs a 25% of the CPU resources that glitches all time when I have the video component active, even not having any video track.

I’m not 100% sure, but since it says it’s copyright is by apple I would guess that it comes from my Logic installation (that is only on that one machine that used to make trouble).
I have the studio 9 dvd version with compressor.

Just a wild guess…


I took out the Quicktime folder DVDPROHDMuxer.component and crash still happens when sample frequency is changed.

I don’t have DVDPROHDMuxer.component and have recently had a crash. I do, however, have DVDPROHDCodec.component. Also, I do not use BM anything.

Should this be removed?

Two weeks since updated to 6.5.3. and DVCPROHDMuxer.component removed. No video engine crashes.


Yesterday, while trying to replace audio in a video file with Nuendo, I had a crash again of the video engine. DVDPROHDMuxer.component is removed here to. Newest Nuendo version 6.5.35. OSX 10.9.5, MacPro HexCore. Annoying.
