Hi Tom,
I have no precise answers to your questions, so that's just a quick
message to let you feel not completely on your own on this topic, which
is a complex one and lacks documentation indeed.
Kdenlive's file format depends a lot on MLT's file format, which is
also lacking documentation. Typically, there is no validating DTD or
schema.
Maybe devs will have time to chime in to give you more precise details
on the points you raised.
Cheers,
Camille

With the new Kdenlive version I've got (20.12.3), there are a bunch of new
things I'm trying to get my head around in the project XML. Here's a snippet
with a few of them:
<playlist id="playlist6">
<entry producer="1" in="00:00:00.000" out="00:00:22.042">
<property name="kdenlive:id">2</property>
</entry>
<blank length="00:00:01.042"/>
<entry producer="producer0" in="00:00:01.125" out="00:00:04.958">
<property name="kdenlive:id">3</property>
</entry>
<blank length="00:00:01.208"/>
<entry producer="1" in="00:00:00.000" out="00:00:04.958">
<property name="kdenlive:id">2</property>
</entry>
<entry producer="producer0" in="00:00:00.000" out="00:00:01.083">
<property name="kdenlive:id">3</property>
</entry>
</playlist>
<playlist id="playlist7"/>
<tractor id="tractor3" in="00:00:00.000" out="00:00:34.292">
<property name="kdenlive:track_name">Video 1</property>
<property name="kdenlive:trackheight">71</property>
<property name="kdenlive:timeline_active"/>
<property name="kdenlive:thumbs_format"/>
<property name="kdenlive:audio_rec"/>
<track producer="playlist6"/>
<track producer="playlist7"/>
</tractor>
The above makes a Kdenlive track ("Video 1"). In previous versions, this would
have been represented as a single playlist. Now there seem to be two playlists - one
empty - fed into a tractor.
Here's an example of the new grouping syntax as well:
<property name="kdenlive:docproperties.groups">[
{
"children": [
{
"data": "3:555",
"leaf": "clip",
"type": "Leaf"
},
{
"data": "0:555",
"leaf": "clip",
"type": "Leaf"
}
],
"type": "AVSplit"
}
]
</property>
I have many questions. Help with any of them is much appreciated:
- Why are there two playlists for "Video 1"? What is the purpose of the empty
"playlist7"?
- Entries now have a "kdenlive:id" property. What is this ID? Note in the
above the IDs are doubled: there are two different Entries with ID 2, and two with ID 3.
- In the group syntax, what is the "data" property? As a guess, is it a
kdenlive ID and a number of frames from the beginning of the track?
- What group types are there other than "AVSplit" and "Leaf"? Where can I
find a list of the types and their meanings?
- What "leaf" types are there other than "clip"?
Thanks,
Tom
