Overlaying Character On video
What is the best way to record a character in order to use it to narrate a video?
I have built a Horseshoe character that I use in some horse-how to videos, I have one video that a friend shot and she cut off my recording at the end so I need to superimpose my character over the video and have him narrate instead. I'd like him to point and such so I can make it more dynamic but have no idea how to record and know when to point/when to say to what...
I have the video file, I typically use Premiere pro but could use after effects. I want my character in the bottom right corner but he will need to point to areas of the hoof and such.
