I have found these cool and unique feature to render my animations on high resolution without having high resolution hardware to render my animations on SVG, HTML, CSS and the old SMIL here with the Text:HTML (deprecated) filter, on codepen there are many good samples of cool and easy to adapt animations, will be other reaturem addon filter, generator on future version of shotcut to support this function? thanks for this great video editing / generation software.
This topic has been covered in several posts. It is highly unlikely that Shotcut will have such a feature (replacement for Text:HTML) in the short to medium term.
I use OBS Studio to record my HTML/CSS/Javascipt/SVG animations then include that as a clip in Shtcut.
