The easiest way to try out and learn MLT is by downloading
Shotcut.
You can download it from GitHub.
This fixes a couple of major regressions in the previous version 7.26.0:
melt to render MLT XML with OpenGL effects from movit.Other fixes and changes:
composite transition and the sdl and ndi modules.xml producer.melt -query or melt -query links.transition property to the watermark filter. Now, it defaults
to using affine.affine transition argument to set rect property if supplied.You can download it from GitHub.
This release adds support for subtitles and LV2 & VST2 audio plugins.

The highlight of this release is support for FFmpeg 7 and Ambsonic audio.

The highlight of this release is support animation easing functions via new keyframe types. Also, new versions of the smooth keyframe type is added that avoids overshoots and cusps.
