Yes, but it is a bit limited and requires reading some code and exploring. Here is an example: melt -profile square_ntsc -producer pango text=hello pad=20 -filter frei0r.IIRblur "0=1; 50=0" -filter affine transition.geometry="0=40% 40% 100 100; 100=30% 30% 200 200" That assumes you have gtk2 working and that frei0r plugin. The affine transition can do a lot of transformations including rotation, but it is undocumented outside of the source code. This is an interesting question, in general, about the ways one can support 2D animations (in addition to the above): kdenlivetitle - undocumented but you can mock things up in kdenlive and look at the XML it generates - limited inbuilt animation and filters, but you can always apply other effects in MLT to it. SVG file - GDK and Qt's SVG renderers have none or very limited support for SVG animation, but SVG can be easily generated like anything XML-based. SWF (Flash) - transparent background is supported as in all of the above. Adobe's tool can be very expressive. Requires swfdec, which is no longer in most Linux distros but can be found on github. HTML5 or QML - available via WebVfx MLT plugin on github, but unfortunately it does not make a transparent background/alpha channel. If it did, I would suggest this route for the best expression. Image sequence - find another tool that can output an animation as a PNG image sequence. For example, OpenShot contains python scripts that drive blender to generate 3D-rendered image sequences (or videos, I forget). ------------------------------------------------------------------------------ How ServiceNow helps IT people transform IT departments: 1.
