Look at this Video. Notice the text moving in LED and the reflection of it on the ceiling of the train. I also took a picture with blank LED screen.
I want to add my own text marquee-ing through the LED in the picture. Everything will be static as the photo except the text in the LED and its reflection.
What software, and what actions do I need to do to achieve this? Any tips and tricks please? I have a Macbook Pro i7. Freeware options are more preferable.
