Hi,
In shotcut, the <consumer> tag is used in the playlist's xml to pass consumer
arguments, allowing to render a playlist file with melt whitout passing extra
arguments.
I am considering using the same approach for Kdenlive, but there is one small
missing feature for us:
it would be useful to allow rendering only part of the playlist using this
method. My idea was to allow in/out attributes on the consumer that would then
be passed on the producer to allow rendering only a part of the project.
A simple patch to melt, like mine below, implements the feature.
Would you be ok to include such feature ?
Thanks
Jean-Baptiste
