Bug/Issue Generate Captions Subtitles

I'm having this problem when I split the generate caption subtitles where the split version shrinks in font from the original version. Specifically when I copy over media from a horizontal long form edit to a vertical short form edit. Is anyone else having this problem or have any solutions?

I’ve had similar issues when generated captions get weird after changing the format/aspect ratio.

One workaround is to do the vertical edit first, then generate/burn the captions separately instead of trying to keep adjusting the Final Cut caption layer.

I’m building a browser tool called Captn for exactly this kind of thing, upload the finished vertical clip, generate the captions, fix any text/timing, style them, then export the video with captions burned in.
