SUMMARY Currently, the Kdenlive subtitling tool introduced in 20.12 don't have any setting options, if user enters plain text, it will render subtitle to the video using the system default font, which may cause problems. For example, when using Windows, it may use a non-free font. STEPS TO REPRODUCE 1. On a system that uses non-free font by default (Windows for example), use Kdenlive to edit a video 2. Add some plain text subtitle 3. Render to file and see the result. OBSERVED RESULT It will use the non-free system default font. EXPECTED RESULT Offer an option in the Configure Kdenlive dialog to allow set the (default and fallback) font that will be used and use that instead. ADDITIONAL INFORMATION Probably useful links while doing the resourcing: https://www.mltframework.org/plugins/FilterAvfilter-subtitles/ I read the source code a little bit but sadly don't find where did the subtitle preference happen in the code. I guess maybe it's in /src/effects/effectstack/model/effectstackmodel.cpp and it tell MLT to use "avfilter.subtitles" and the I lost my tracking. Not sure what other information should I provide and please tell me if any additional information is needed. Hope that helps.
Thank you for the suggestion and hints. The idea is to introduce *.ass subtitle format which includes different fonts and colors (maybe with 21.08).

Thanks for your report. You are right, I didn't previously notice that a simple styling can be achieved through the force_style option of the ffmpeg subtitles filter. This way, it is very easy to introduce a basic styling (all subtitles in a project will share the same style). Will make some further tests tomorrow.
