Hi. With kdenlive-20070815 if I use

track 0 ---> image png white 16:9

track 1 ---> dv clip1 (pip track2 - transparency 50)

track 2 ---> dv clip1

track 0 has a transparency that should not have.

Usually I using other NLE programs (Avid Xpress Pro) and I do not know if I have misunderstood how the pip work in kdenlive or is a bug. Someone can confirm?

Hi blazar,

this is not a bug ;) .

According to your project, the normal behaviour in kdenlive is that you'll see only the white mask. This is because kdenlive is reading tracks up to down, so if in track #0 you have a white clip without any transition applied, this is what you'll see as output.

The reason why you are seeing also the clips in other tracks is, I guess, because you've defined the image clip "maschera.png" with transparent background (double click the clip in the project tree and you can confirm). And that's also the reason for this clip to mix with the others.

I do not understand the reason for the white clip in the first track, but if you remove it you'll see how the PIP transition between the other clips is working OK.

If you let us know what's your desired output, I'll try to help or at least confirm if kdenlive can cope with it.

Regards.

Probably I have not explained very well my matter... :oops:

I have choose transparency in track#0 for add white 16:9 (like some video music) at my clip, but white color has a transparency that should not have.

I have made an image whit gimp :D

Hi blazar,

I understand now your idea :!:

But I do not think kdenlive can cope with it :oops:

I've reported the bug in the bug tracker, mainly because I'm not sure which is the right way of working for kdenlive, to have always transparency or never. But what is not correct is to have background transparency and change to full transparency when the PIP transitions is applied.

Regards.

It's not correct :lol: For now you can do this:

track 1 ---> dv clip1 (pip track2 - transparency 50)

track 2 ---> dv clip1

Export Project track1+2

Import file track1+2

track 0 ---> image png white 16:9

track 1 ---> dv clip2 (track1+2)

It's all.

... background transparency only ... ? :mrgreen:



Thanks for everything.

blazar, if I understand you well, your observation is part of a more general problem, that is, that a transition on a clip in a lower track of the timeline is applied to the clips on the tracks above it as well, but only if those upper clips have a transition themselves.

I filed a report regarding this behaviour here: http://www.kdenlive.org/bbforum/viewtopic.php?f=9&t=439. You may have a look. The solution with exporting and re-importing parts of the timeline is very unsatisfying, so I think this should not be the default behaviour.

Cheers, cjubon.
