Depends how arty you want it?

How long does the driven wheel take to cross the frame? 3 seconds 10 seconds?

Grazie

You could use a Bezier mask on the text event to reveal it just as the car is passing. The Bezier should follow the contour of the back of the car to make it look like the text is coming from behind the car.

Drop in the text to position.
Click the Pan/Crop icon on the text. Choose the MASK tickbox at the bottom of the keyframer. Be sure Sync to Cursor is enabled.
Place your cursor where the text should be invisible (as the bike enters the screen) and make a mask around the text using the anchor/nodes tool. move to next frame or 2-3 frames later, and draw another mask, or just widen the mask you already have. Keep moving 1,2, 3 frames at a time, enlarging that mask. You'll rapidly figure out the timing. You *may* even be able to have only two keyframes in the reveal, one at the start and one at the end if you figure out the timing correctly.

Timeline Layout:-

Track 1: "Car" Event

Track 2: "Text" Generated Media

When you get this under way, you could try all sorts of movement for Text; make the Text interact with the colour/saturation of the road/dust - lots to try out here.

Grazie

Great to see you back Spot! Hope you're doing alright.
