Description Lance Rissman 2021-05-05 15:21:12 UTC

SUMMARY
With a 4K video, to have a single character fill the screen, a font size of ~1500-2000 would be required.   The UI is limited to 1000 for font size.

STEPS TO REPRODUCE
1. Open Kdenlive (21.04, or Master 751 (21.07.70))
2. Select Menu:  Project-> Add Title Clip
3. Add some text and use the UI to type in font size or increase font size.

OBSERVED RESULT

UI will not increase beyond 1000

EXPECTED RESULT

US will allow higher value to properly support large fonts on 4k frames.

ADDITIONAL INFORMATION

It might be related to this hardcoded entry I found in the source code: https://invent.kde.org/multimedia/kdenlive/-/blob/master/src/ui/qtextclip_ui.ui#L35

Workarounds could be applied (and do work) such as having a font size of 1000 and then adding a transform effect to the clip or using an external program like Krita or Inkscape and importing those clips.

Thanks for your report! Yes this seems to be the related source code. Do you have (at least a little) knowledge in git? If so it would be really nice if you can open a merge request on GitLab: https://invent.kde.org/multimedia/kdenlive/-/merge_requests
