Chris is right, a feathered mask will probably be the easiest approach for this and and would be very effective. I’ve uploaded a project using a luma matte method that you may find a bit more organic. I didn’t have a great smoke wipe, so I created one from a static smoke charge, so please overlook the edges.
Step 1 – Create a smoke comp and add a levels effect to blow out the whites and crush the blacks, this is the layer that will drive the wipe. When we drop it into the final comp the black areas will allow the text to be visible, and the white areas will cause remove the opacity.(In my case I have 2 smoke comps, one with levels effect, one without since I had to create smoke wiping across the screen).
Step 2 – Created a final comp and bring in both my smoke layers. Add two text layers. Duplicate the Smoke Levels Layer and place it above both layers of text. Now just change the text track mattes to “Luma Matte Inverted”. Place the normal smoke layer as the top layer and change it’s transfer mode to “Add”. When the smoke was at it’s fullest I quickly animated the opacity keyframes of the text layers to switch between the two.
Take a look at the project I created, hopefully it gives you a good starting point for you own project. 6911_breakingbadfolder.zip
