Hello again, I made some improvements and implement the typewriter effect as a real mlt effect. You can try it out by yourself. It means no more needs to play with original kdenlivetitle producer as a intended to do in the beginning. This typewriter can be used on every supported producer, but currently only kdenlivetitle is supported. If you need it for another, let me know and I will do it.
It is distributed as a additional library for mlt. You can also try it first out on my demo page http://rlalik.com/demos/typewriter/ to learn how to prepare a proper pattern. To use it with mlt/kdenlive: 1. Install additional effect library from this repository: https://github.com/rlalik/mlt_extra_modules It is important to install it in the same location like original mlt installation, e.g. /usr/lib/mlt/, most likely you need to call: ./configure --prefix=/usr make sudo make install Adjust --prefix value if needed. 2. Download and copy this file https://raw.githubusercontent.com/rlalik/kdenlive_tw/cdata/data/effects/typewriter.xml to the kdenlive effects directory, e.g.: /usr/share/kdenlive/effects/ 3. Open kdenlive, create new title page and put a TW pattern text enclosed within markers, e.g.: |^|:c[4]{Example}|$| Markers are required in order to extract the pattern from the xml data of the kdenlivetitle producer. 4. Add typewriter effect to the title on your timeline. Regards and enjoy it, Rafal
