Summary0001066: rendering breaks all my composite transitions (preview ok)
DescriptionI have a big problem with a vide project iam working on since 2 month.
In the the working progress i rendered some areas to see if all works fine. This area rendering was ok. But now when i was finished i tried to render the whole project and i was shocked because all my composite transitions are broken :(

During working i added a new video track to the project. Maybe this could be a reason?

To show the broken composite transitions i took a special scene.

I've attached screen.ogv which shows the preview off this scene. It is ok.
When i select this scene as rendering area and render it it is also ok as shown in attached fine.mpeg.
The broken.mpeg is a cut of the whole project export which shows the scence with broken composite transitions.
The last file i attached is a *.kdenlive project file where this problems occours. It is just a part of the main project.
TagsNo tags attached.

Playing the project file with "melt projectfile.kdenlive" also shows the broken composite transitions.

For the composite transitions at 14:15, could you perhaps try selecting the lowest layer (the .png file) as target layer? Instead of automatic? If you didn't do so yet this might be worth a try.

@Granjow: Thx for the hint. I've tried that but unfortunately it doesnt help.

As jb told me i reduced the project file just to the scene end delete everything else. Now the file plays fine in melt. So i think the problem must be somewhere before ...
I attached the reduced project-file and needed files.

As you said, the attached reduced project works fine, so it is very hard for us to debug it... The problem is probably related to a transition that breaks something. Maybe you can try to delete them by group and try to understand which one blocks...

After finishing the project by rendering in 5 parts (which works as partial rendering) and after this merge them with mencoder i've got some time to figure out the problem.

at first i removed every transition one by one from 00:14:05:00 backwards. no success.

then i removed every clip one by one from 00:14:05:00 backwards. at first it looks if it doesnt help, but when i delete the clip "vorspiel.wav" from position: 00:00:16:10 (duration: 00:02:59:17) from track 2 the playback in melt works again (i think rendering will also do but not tested).

Could it be a problem to add a wav-clip to a video/audio (and not audio-only) track?
Or maybe it was the track i've inserted. (Sorry i dont remember)

I hope that helps to understand what caused the problem.

I think this bug is quite old and that it is too difficult to reproduce it. I tried to render the example project and the rendering was fine with kdenlive 0.9.2. So I think we should close this bug. Thank you for reporting !
