VSE - Meta strips - preview image seems to disappear

Hope you can help me with this:

May it be the intention, that meta-ing a couple of strips returns no image (2) in preview window? When un-meta is chosen, the image returns (1).

To me a quite useless behaviour unless someone could tell me whether it has be so or – even better – how to view the meta content?

Kind regards,

The metastrip treats the lack of visual information as blackness, and puts it over underlying strips. You need to make your sound-metastrip “alpha over”, as weird as it may seem. Or move it underneath.
Someone recently posted a wish about “alpha over” as default for new strips/stuff, and I couldn’t agree more…

Hi encn

Great, it works. You’re right about the alpha-thing, yet I have another issue on top of that: Have you experinced any messing-up in the sound? When metaing the strips the sound dissappear …

Even after unmetaing it persist until hitting “Alt-R”-keys (reload strips). Have tried to “open” metastrip with “tab”-key and reload this way - maintaining the meta-group - but no effect either.

And of course: I’ve “Refresh Sequencer”-ed

Any idea?

Thanks also for your comment about “VSE: cannot undo strip cuts”. We can conclude that Blender should’nt reject “undo” in this case. I’ll keep an eye on other possibilities as you stipulate.

Kind regards,

Jan. 3rd, 2013 UPDATE:

Have actually made a job in late december using the VSE and must confess, that I could’nt restablish the above mentioned error, so meta strips seems to work as intended. I must have messed up something in the proporties yet unknown.

Best wishes: A happy new year from Copenhagen.
