I have a simple question which I am sure has a simple solution. I have an image and I have a video with an Alpha mask.
All I would like to do is overlay the image with the video as it is playing. The video is of water filling a screen. I'd like for the water to overlay the image as it rises.
If any other resources or details are required, please let me know.
1- Put the video on the Top of the image
2- Click on the Toggle switches / Mode or ( F4 ) in the Bottom of the Timeline
3- you will See a coloum T TrkMat : select Alpha Matte
Hope this will help .
If it does not work ,, Could you please Upload a screenshot .
