Andrew:
But if I load video file (1 video track, 2 audio channel) AND add effect to video track - I only can effectively switch on/off content/titltlebars for audio tracks! Video track remain always with its content and titlebars. They sort of 'blocked' by effect track from this change, even if I remove effect itself!
I was wrong, what I thought was a bug is just the patchbay at work to the
left of the timeline. In the patchbay to the right of the default "Video 1" is a small right facing arrow. When you add an effect the patchbay right-facing arrow "expands" to make room in the timeline for the effect bar. And you will see that the right-facing arrow becomes a down arrow and the "Play track", "Arm track", etc. symbols all become visible. Once the patchbay expansion is enabled, you have to disable it to get back to the right-facing arrow space size. That is why the title will still show, because it is expanded. But you can un-expand it and then the title no longer shows. I hope this makes sense. If not, I can add pictures! gg/Phyllis
