Creating custom "Effects"

You are correct. The XML files simply refer to MLT filters. I am not
aware of a master list of filters for MLT. I dug through the source
code looking for many of them. You should be able to add any MLT
filter using the XML files.. if you get all the correct settings.
Good luck!

Thanks,

Hi Jonathan, thanks for the explanation... guess "Filters" is the correct term, not "Services".

I was hoping *not* to trawl through the MLT sources, would you mind listing a few of the files I need to be looking at?

Would also be worth documenting this "Filter" list somewhere for others (user manual?), I'd be happy to e-mail whoever the complete list for inclusion.

Many thanks again.

Hi renderguy
Perhaps, You could find more explanation here : http://openshotusers.com/forum/viewtopic.php?f=25&t=16
Thanks you for the interest than you bear

If you have "melt" installed, you can get a list of the filters.
However, the sources of some filters are in the MLT code, and some
filters are in external libraries. I'm not sure the exact place to
look. =)
$ melt -query "filters"

Thanks,
-Jonathan

Hi Oliver/Jonathan, thanks for the pointers.

I've just installed "melt" and queried the available filters, I'll post anything useful (for inclusion) to the bug tracker... as suggested on your forum post (Oliver).

Many thanks again.
