How to transform

SUMMARY

Subtitles must be editable. I want to add "Pop in" effects to captions like MrBeast does and split subtitles into 1-word captions (2-3-4+  words or certain symbol length, amount of words per line, amount of lines, centering). Also I need to set certain font to every title clip/subtitle at once.

Steps to do it:
1) Speech to text the input audio. We have speech-to-text thanks to whisper and vosk. 
2) Split subtitle sentences into 1-word captions on the same places in timeline as previosly. **Need to implement**
3) Convert subtitles to hardsubs (Title clips on the same places as subtitles and in exact amount). **Need to implement**
4) Apply same "Pop in" effect, change font, font size, position on the screen to the group of title clips all at once. 
4.1) Implement "Pop in" effect in kdenlive and many more fancy effects (based on Existing ones or create from scratch).

The similar workflow can be seen in Premiere Pro or Capcut
