I find I can only get my vertically scrolling text to centre properly by placing a full line of blanks somewhere in the text.(I’m putting them in the first line.) Similar problems arise with right-aligned text. I guess lots of people would want vertically scrolling titles, so nice of this could be fixed.
Here’s the html that follows the javascript in the “simple_scroll.html” file that Shotcut produced. My dummy line of spaces is included. I’ve played about pasting this into an html file which I can then open with my browser. The centering behaves just like it does in Shotcut, both with and without my extra line (except it doesn’t scroll of course). So I deduce that the problem is in the html. Unfortunately my skill in html and css is not good enough to identify the exact problem.
<style>
body {
position: absolute;
margin: 0;
}
</style>
</head>
<body style="font-size: 72pt; white-space: nowrap;"><div style="text-align: center;"> </div><div style="text-align: center;"><font face="Arial">This is a test</font></div><div style="text-align: center;"><br></div><div style="text-align: center;"><br></div></body></html>
The problem arose in a 1280x720 video.
I’m using Shotcut 19.10.20 under Windows 10 home v1903 build 18362.476 on a 3 Ghz Pentium G3220
with 4GB of RAM and a 1920x1080 display. Been using Shotcut happily for a year or two with very few issues, though haven’t been very adventurous in my use of filters.
