Overlay to hide old logo on existing movie
I have a series of old movies (tutorials) created using my original logo that has since changed. I'd like to use an overlay with the new logo.
When I drop the new logo on top of the original it only lasts four seconds and fades away revealing the old logo. I've tried dragging the new one over the length of the original movie, five + minutes and longer, but it repeatedly fades away then comes back over the length of the movie, it's very distracting.
Is there a way to 1) stop the fading, and 2) stretch it over the entire length of the movie? I have over 90 short tutorials/movies I need to do this for and would like to find an easy solution rather than having to re-record all of them just to replace my old logo with the new one.
