I plan to add more interpolation capabilities at the framework level similar to the way mlt_geometry works today. Therefore, I suggest using a single property with a value syntax following: [frame=]N[;[frame=N]]*. When "frame" = -1, then it means the "end." (-2 means second last frame and so on.) You can actually use mlt_geometry for this now as it actually a fairly generic thing that contains and interpolates up to five floats per key frame allowing all sorts of characters (except '=') as delimiter. (See man strtod for the rules - whatever endptr points to ought to be the delimiter.) -- +-DRD-+ ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Kdenlive-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/kdenlive-devel
