hey! have you done any experimenting with the text/graphics settings in the editing software you use? if it's premiere, i think it's super powerful and is very good at not including extraneous textbox edges from screenshots. and it's super easy to keyframe them around just like you do already. except this time the text is in the program instead of in your notes program. may be a simple game change of copy/paste instead of screenshot/import. i hope this was helpful or enlightening in some way
i've tried using the text controls in the video program, and i thought it was a great idea for a hot minute and then i realized i have much more control with the screenshot method. i have special tricks to standardize alignment and get rid of the lines
