Hello everybody,
I would like to add some on-screen titles over my sport videos (at this time, tennis matches), so that I could easily (manually) update the score lively while reviewing the edited video. The manual update process has to be recorded as a new video track to be added automatically to the project.
Has anyone a solution for this or should I have to write an effect or a plugin from scratch on my own?

Please drive me to the best approach as I am new to the software infrastructure.
Thanks
