I highly doubt anyone will help you with this, and I do not have time to investigate it as a bug any time soon. I suggest you tinker around to...

In general, I recommend people to stick to composition patterns that one can observe in the XML outputs from `melt -consumer xml`, Shotcut, and Kdenlive. SImply reading the documentation and...

You might be making some graph configuration that is unexpected by the xml consumer. You can try to fix consumer_xml.c for it, but this is not a good sign. Even...

Instead of cutting the tractor, try setting in and out on it. Alternatively, set in and out on the consumer.
