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
