I’m not an expression expert by any means, but here’s my 2 cents.
1. Make a new layer and apply the “slider” effect.
2. Name that layer “slider”
3. Choose one of your video layers and put this expression into the anchor point value:
x = anchorPoint[0];
y = anchorPoint[1];
z = thisComp.layer(“slider”).effect(“Slider Control”)(“Slider”);
[x, y, z]
4. Copy and paste this anchor point expression to all video layers.
5. You should now be able to move all of the layers by just animating the slider value.
Hope that works for you.

PS I am sure there is a simpler expression, but if it works, it works.
