I'm new to this forum.
So first of all I want to say: "THANK YOU FOR KDENLIVE!" :-)
It's the single most usable video editor for Linux.
I know there are others but either they are too subborn to
be called "intuitive" or they lack certain functionalities.
I admit that also Kdenlive has a number of issues where it
can be improved but it has (IMO) much less issues than all
other available programs.
But enough of the flattering stuff ... ;-)
I'm writing this post for another reason.
I'm currently at the beginning of a project involving several
videos (composed from other videos), slideshows, computer
generated grafics and some animated DVD menus.
I just finished the first video (using Kdenlive of course).
During the process Kdenlive messed up my project file
three times and was unable to load it properly afterwards
telling me about invalid producers or simply dropping clips
from the time line and so on.
I managed to rescue my work each time by editing the project
While doing this I notices something that I want to ask here.
(Maybe it's just me not understanding the full logic behind it.
But maybe it's somthing that should be improved.)
I have exactly 7 media files involved in the first video. It is
4 movies and 3 sound files. Some clips in the time line are
parts from the movie files where I stripped off the sound or
sometimes I took only the sound of a movie dropping the pictures.
(I assume these are normal use cases for video editing.)
This means from my understanding that I have 7 "producers" of
clip material (no matter if video, audio or both) and everything
in the time line should only refer to the producers as parts of
But when I look in the project file I see 22(!!!) producer
sections inside the
Why is this?
Well, I generally know why. It's for sure the way I edit the
video sequence. There are certain actions in the editing
process that create a "producer" in the project file (beside
adding media files).
My question is: Why are there "producers" created with other
actions than adding media files?
It seems completely unnecessary and error-prone to me.
Some of these producers were obviously created for clips
without sound or clips with sound from a video but without
I think this structure leads to redundancy and confusion when
loading the project file. It would be better to have only ONE
producer section inside
All mlt.playlist.entry sections should refer to these solitary
I edited my project file following this rules and it worked
every time. (Means Kdenlive and Melt can handle it this way.)
In my opinion the mlt.producer should not know if the media
file contains only audio or only video or both. This information
should be part of the mlt.playlist.entry section because the
user can change these parameters for every mlt.playlist.entry
in the GUI separately.
I hope my questions and remarks are understandable. In case of
questions I will try to elaborate.
