Attachments:	kdenlive save file with the intended stack kdenlive project with just two clips, renders fine. Kdenlive project with sub-project on the timeline

Description Evert Vorster 2015-12-01 09:21:39 UTC

I have many GoPro clips that have a deep stack of filters that are applied. 
To save time, I thought it would be a great time saver to add all the clips to the timeline on a project, and then load that project in another one and only apply the stack once. 
This worked fine until I came to rendering that project with an embedded project. 
It crashed every single time, no matter what encoding I have tried.

Reproducible: Always

Steps to Reproduce:
1. Add two clips to a timeline, and save project.
2. Start a new project, and load previous project as a clip.
3. Add clip to timeline
4. Hit Render

Actual Results:  
Project fails to render.

Expected Results:  
A rendered project

Thanks for your report. I cannot reproduce. Can you please give more details :
* Are you using the same project profile for both projects ?
* Which rendering profile are you using ?

Attaching the project file that causes the crash to the bugreport might also help.

Kdenlive project with sub-project on the timeline

I get the following crash information:
Rendering of /data/Kdenlive/untitled.mp4 crashed

Is there a way of getting more debug info from the render, maybe a way to render a project from the command line?

This is still an issue

Comment 6 Evert Vorster 2016-01-01 07:00:17 UTC

Seems it works fine now, on git master 2016-01-01
