Add text to video which tracks

[EYEREX]

Hello all just wondered how hard it is to add text to a video which tracks part of the video as it moves, don't need it to show up all the time just now and then

example below

How good is you c++ programming? You could use OpenCV to bootstrap a lot of the processing. You will need some clear defi icing visual characteristics for the object recognition and then use some thing like a particle filter to help with the tracking.

Pretty easy in most Non-Linear Editing packages. Simply create the text and then animate it over the course of how long you want it to display. Should you need to move the text in a bit more complicated fashion, you can add keyframes to control it.

Doing programming to add some text to a video strikes me as quite a bit of overkill.

Depends if you want this to be an automated process or done by hand. The advantage of a software solution will come when in future videos the user just enters a few parameters and the entire video is automatically annotated. Rather than spending hours doing it by hand for each new video.

It doesn't take hours to do what I've suggested, NLEs these days will do it all for you.

Your suggestion also doesn't work unless you can do programming, which it clearly sounds like is something you are familiar with. If it is what you would do, then fair enough, but its not a solution that is likely to work for the majority.
