Hi,
just want to ask here before filing a bug report: just started work on
two new Kdenlive projects. For convenience, I cloned the first project
in an early stage to be used as the starting point for the second
project. And then I noticed something concerning preview rendering...
1. While working on the first project, I preview rendered the first
few seconds consisting of the titling for this episode #23. So far, so
good.
2. Then worked on the second project and replaced the title for this
separate episode #24. Now, the fun starts: when preview rendering the
same zone for the titling, Kdenlive happily picked up the preview
rendering from episode #23, which I can clearly see as preview now
uses the wrong titling.
So, this brings me to my question: does the document identity
correctly change when I copy a project?
Good question! I also thought about it and have not found a solution yet.
The project id is created when the document is first created and
consists of a timestamp.
This timestamp is then used to create a temporary folder in
$HOME/.cache/kdenlive, and the audio/video thumbnails and preview files
are stored in this folder.
This way, the project file can be renamed / moved without losing the
temporary data. However if you create a copy of the project (either to
try a different edit or to start a new project based on the current
one), the document id is not changed, so the same temporary folder is
used, leading to potential conflicts of preview files (but on the other
hand it can be nice to have the audio/video thumbs already created).
I cannot think of a way to automatically handle this...
Maybe we could introduce a "clone" feature that would set a new document
id and copy temp data to that new folder ?
Any idea/comment is welcome.

Best regards,
Harald
PS: As always, doing actual projects on the bleeding edge...
