I just recorded a video of myself talking with background as white screen.Now i want to add my photo in that video, so that the final output should be like myself talking in a video with my photo in the background, replacing my previous white background

To replace a white background with an image, you need to use a Luma Key. A Luma Key is like a Chroma Key, except that instead of using a color value (such as green or blue, usually qualified also by a certain level of luma), you will use only a luma value (such as anything brighter than 200 IRE).

Most NLE software have both compositing and keying functionality. But now that you know what the effect is called, you can research how to access that functionality in the software you are using (or will use).

  • Thank you for this... Do you think it is doable in iMovie? I have not found it...

This might be too late, but do try out Adobe Presenter Video Express. There is a feature called - magic green screen, which will make replacing background in videos like you mentioned very simple (it's basically automatic). There is a 30-day free trial, so I guess this should work for you. Disclaimer: I work as a developer for the product.
