Hello,

Sorry for replying so late, it took me several trials to figure out what was
going wrong…

Actually the effect disappeared from MLT since
ca0fc8d7b7d93cfde005d4cc76fbf0c5a913084a (March 2016) to fix a long standing
crash with titles in Qt5 with multithreading: effects haven't been ported to
the new drawing routine.
(Note: it then should be available in 15.08 and 15.12?!)

But it appears that the old code was kept, and is still accessible if you add a
"compatibility" property to your text XML element.
So before any change occurs (I'm quite slow to code anything), a temporary
workaround to get the typewriter effect is to:
- open your .kdenlive file with a text editor
- find your title text string; it is contained in an encoded XML tag:
 &lt;content [many properties]>Your text…&lt;/content>
- anywhere in the properties (eg just before ">Your text") add the following
properties:
 compatibility="1" typewriter="0;25"
with 0 being the start frame of the typewriter effect, and 25 the interval (1
sec per character on a 25fps project)
- note that 'compatibility' titles use the old rendering code, that crashes all
the time with multithreading: set MLT threads to 1 in Kdenlive preference

Good luck :)
