Dear all
Thanks to your help I got webvfx running.
Now I'm trying to add a webvfx title to my video at some point in the
video, overlaid on top of the video.
If I'm using webvfx as a filter, the title is overlaid on top of the video,
that's great
<mlt LC_NUMERIC="en_US.UTF-8">
<producer id="0">
<property name="resource">video.mp4</property>
</producer>
<tractor>
<multitrack>
<tractor>
<multitrack>
<tractor>
<playlist>
<entry producer="0" in="0" out="240">
<filter>
<property name="mlt_service">webvfx</property>
<property name="resource">plain:index.html</property>
</filter>
</entry>
</playlist>
</tractor>
</multitrack>
</tractor>
</multitrack>
</tractor>
</mlt>
But now I'm trying to add webvfx as a producer, to add the title over the
video one second after the video has started.
It does not work, the video disappears when the title appears, it looks
like the alpha channel is not taken into account .
<mlt LC_NUMERIC="en_US.UTF-8">
<producer id="1">
<property name="resource">video.mp4</property>
</producer>
<producer id="2">
<property name="mlt_service">webvfx</property>
<property name="resource">plain:index.html</property>
</producer>
<tractor>
<multitrack>
<tractor>
<multitrack>
<tractor>
<playlist>
<entry producer="1" in="0" out="125">
</entry>
</playlist>
</tractor>
</multitrack>
</tractor>
<tractor>
<multitrack>
<tractor>
<playlist>
<blank length="25"/>
<entry producer="2" in="0" out="100">
</entry>
</playlist>
</tractor>
</multitrack>
</tractor>
<tractor>
<playlist>
</playlist>
</tractor>
</multitrack>
<transition id="composite" in="0" out="125">
<property name="a_track">0</property>
<property name="b_track">1</property>
<property name="mlt_service">frei0r.composition</property>
</transition>
</tractor>
</mlt>
So I have two questions :
- is there any way to have some alpha channel when using webvfx as a
producer
- or is there any way to add a filter only on a portion (in / end) of a
track ?
Thanks again, and have a nice New Year's Eve !
Best regards
Geoffroy
