Any suggestions or updates about such compound.

We did not create such a compound since it can take many different forms. You can put together your one according to your desires and then you can save it as a Linked Compound and use it in any number of your scenes.

The transitions can be achieved by creating On-Off animations, similarly to the ones you can find in LowerThird_Example.xcomp.

Thank you I think that my question what's so clear 

First part was about general crawl compound that allowsow users to select different data sources like xml,rss,txt ,etc as ticker text source.

I think that the new crawl* compound in aximmetry 2019.6 have the solution for that part.

Second part about simplify the transation between different lower thirds and newstickers for example hide news ticker show big lower thirds then change this lower thirds size to show tickets .etc

So I mean any compounds to do transitions between different lower thirds and newstickers?
