WebVfx v1.1.0 released

Jun 15, 2019

You can download it from GitHub.

MLT continues to maintain and extend the WebVfx add-on that lets one use HTML and Qt QML technologies for a video asset or effects. Back in November, 2018 we released v1.0.0 as it has proven fairly stable and useful in Shotcut for a few years. Here are the enhancements for v1.1.0:

  • Added support for alpha channels in MLT video for input and output.
  • Added a transparent property to the MLT filter. When the property is set to 1, this gives a filter a transparent white canvas for drawing while the MLT video image is still available through the JavaScript extension. This facilitates using WebVfx to draw the alpha channel independently of the MLT alpha channel.
  • Added support for getting a MLT rectangle property (mlt_rect) as a JavaScript object with properties: x, y, width, height, and opacity.
