アニメーションの作り方

Add the graphic to your timeline, then go to Effects > Wipe > Linear Wipe and drag the effect onto the start of your graphic. Select the transition on the clip, open the Effect Controls panel, and set Angle to 90 degrees and Wipe Feather to 0.0.

You could also place the graphic on a video track above the main video and keyframe the crop effect.

If you have the graphic already it would be a simple mask animation to reveal the graphic which can be done in Premiere or After Effects. I’d suggest looking into the masking post in this forum
