You are right for sure. I will try to see if I can do the same without
changing the profile.
GStreamer would be a better fit for sure, and I tried, but the bindings
weren't mature enough at that time. I may check again.
Thank you all for your support and patience.

It is also due to your low understanding of the MLT framework in general.
Studying the XML is not just to learn the properties of a filter. It also helps
you understand the coordination of MLT framework services. You are work
Thanks Brian.
My use case is explained in my prior message,

As I said, what I am aiming for is for creating functions where I can
compose what I do with videos. My final profile will be something standard:
16:9 720p or 1080p with 25 or 50 fp
I would suggest:
1) Create a producer to open V1 (it does not matter the profile)2) Query V1 for
the size3) Close V1 (delete the producer)4) Create a producer to open V2 (it
does not matter the profile)5) Query V2 for the size6) Close V2(delete the
producer)7) Calculate the profile that you wan
Right now, when I stack videos vertically, I output the Tractor and the
Profile: "tuple[tr:Tractor; p:Profile] "
proc stackVertically*( v1,v2:Producer ):tuple[tr:Tractor; p:Profile]
Later I apply the returned profile to the consumer:
# Call the function to stack vertically two videos.
