framecurve (framecurve.org) file handling gem for Ruby.
This gem includes a handful of classes for manipulating framecurves and is intended as a library for when you want to do something with framecurves from within Ruby. This will also power the online framecurve validation service once it’s online.
The main binary of the gem is called framecurve_validator, it will validate framecurve files passed in the arguments and report any errors found in the files to STDERR.
$framecurve_validator somefile.framecurve.txt another.framecurve.txt
This is handy when you wrote your own piece of software that exports framecurve files or you want to make sure that a framecurve file you have received conforms to the framecurve specification. This tool will also note all the deviations from the spec in terms of recommended headers and comments and report them to you one by one.
This gem includes an application, framecurve_from_fcp, that will extract Framecurve files from a FinalCut Pro XML files (the version you need is *XML Interchange Format Version 4*). It will dive into your sequence and find all clips which have time remap effects on them, and for each of these clips it will write out a <tt>.framecurve.txt<tt> file that you can convert into other formats or load into applications for which we provide framecurve scripts. This file will include all of the motion keyframes that have been applied in FCP.
$framecurve_from_fcp_xml my_edit.xml
will write out a number of framecurve files, one per timewarped clip in your sequence (they will be appropriately named with the track index, clip index and clip name so that you can trace which ones relate to which clips in your edit).
If you need to extract from a format written by Flame or Smoke, install the flame_channel_parser gem. This gem provides the binaries framecurve_to_flame and framecurve_from_flame which will create framecurve files or convert them to a variety of Flame-supported setup formats. Refer to the flame_channel_parser gem documentation for more information on these.
