How to center and align things in Premiere Pro? One thing I always face trouble with is aligning things in Premiere Pro.
In Photoshop, if you have an image you can just align it with align tools. If you want to align multiple things, you group them and align them in left, right or center etc.
I want to achieve something like that with videos.
For example these 3 clips are placed randomly with a guess that they are visually aligned. But they aren't perfect. I just adjusted them manually.

So how can I a) select those 3 clips and align them horizontally (marked by yellow)? b) Align the right most 2 clips horizontally to each other (marked by green)?
Right now all things seem aligned but I did hit and trials and it took a lot of effort.
Something like this is usually not done in Premiere, since it involves motion-graphics that are way easier done in After-Effects.
If you have to do this in Premiere though, the only way to make sure that - the two smaller pictures for example - align perfectly on their vertical axis is to take a look at their position and put in the same value for the x-axis (the first value).
