Hi Ken, Your post was very timely for me because I’m just experimenting with scrolling movie credits using HTML overlay too! Your method of creating the scrolling text in a html editor then capturing the screen as it plays in a browser was very useful. Using this method I just came up with this video:
The HTML code I used for the scrolling text is below if anyone would like to experiment with this.

Copying the code from the pdf, putting it into notepad and saving it with a html extension should enable you to open it in a browser.
Notice it uses the @keyframes credits CSS rule rather than the marquee tab and it scrolls very smoothly in the browser.
I adapted it from an example html from a site called codepen: It’s here:

What I did was to screen capture (as an mp4) the output from Chrome, using Sharex, then import into Shotcut as well as a short video of clouds which I took using my Panasonic camera, applied a chroma key filter to the text video, and merged the two together. I’m not there yet - the text scrolling is choppy (I probably needed to screen capture it at 60fps, I think it was only 25 or 30fps). Also the green colour is still appearing on the scrolling text.
Will experiment further when I have time but thanks Ken for helping me along the way with this.
My ideal goal is to find out if I can import the HTML code into the Shotcut HTML editor and get it to work that way. I have tried this but can’t get it to work yet.
