Hi there, I mainly have Zoom recordings for lessons that I teach online to my students. It includes videos with presentation content on the main screen and a small-PiP-speaker layout. Will FlexClip be able to create short clips (Vertical short-form video) of videos with the presentation content at the top half zoom automatically to the relevant parts of the lesson and the speaker's talking head at the bottom half? Will the talking head part be lower quality because of the source video? How will we get a better quality output for both the talking head and presentation content? Please confirm. Thank you.
