I’m started from tangolerra project made by Franco Iacomella and after an hard job with svg I made my personal mochup of Cinelerra called Cutiehd. But when I started to work on the mochup of Cinelerra 2.1cv I tryed to enable again the support of font antialias (xft), write a draft of Utf-8 support, rewrite some parts of titler code and adapt the svg plugin from the Cinelerrasv by “Simeon Völkel”. I know that these features can generate instability, so I decided to make a new package with it’s name and icon called Cinecutie, that can be consider more as “mochup” than a real “fork”

Then later, the system combines these annotations with the raw footage and intelligently organizes and “pre-edits” the footage into an Adobe Premiere Sequence.
