You can do this fairly easily with Transforms with masks, or Transforms and Crops. I’d probably go with cropping because crops can be set numerically and masks can’t (or can they? Anyone?).
First effect. Take your full frame clip. Apply Transform and Crop. Set Crop to mask all but top strip. I would calculate your crops in advance so you can set them numerically. Use Transform position to move this masked strip. You may want to set the “Shutter Angle” in the Transform for motion blur. A setting of 180 is pretty common. Often I prefer 60.
Now option-drag this clip up to make a copy. Reset the Crop and Motion for your next strip. To save a tiny bit of work for multiple strips, copy the clip with the correct motion before resetting the crop. If you want to reuse this, save each Transform and Crop as a Preset with a name that makes sense. Or copy and paste attributes or copy and paste all the clips and replace the underlying image.
Second effect. Using the same idea, you can use Crops and keyframes to reveal your image in the pattern you want. Set the bottom for the top row, keyframe the right crop to reveal top row. Copy this clip and change Crop for second row, and so on. This only works if your reveal is rectilinear. For odd-angle reveals, you can use animated masks instead.
There are definitely other ways to do this and no doubt you can find prebuilt presets or mogrts, for both of these, but I prefer to use the most basic tools rather than cluttering up my effects with tons of prebuilts I’ll never use. Shutterstock and Envato Elements are good libraries for pre-builts. Even Adobe Stock. I like searching YouTube for ideas. Tons of YouTubers like Javier Mercedes have tutorials for various effects and give away or sell presets if you don’t feel like building them.
