First you would like to have the same ratio for the two composition, in the pictures the first one (character) is vertical while the second one (capture) is horizontal.
Modify the size of the first one, for example if its 750px x 2000px you should do a 3556x2000px comp, assuming that the second one is in a HD ratio (1920×1080).
Then you need to multiply your source positions by the ration between the two comps.
In this exemple the ratio is 1,85208333333333 because 3556/1920 = 1,852083333333First you would like to have the same ratio for the two composition, in the pictures the first one (character) is vertical while the second one (capture) is horizontal.

In this exemple the ratio is 1.85208333333333 because 3556/1920 = 1.85208333333333.
the resulting expression would be something like that
comp(“2017-07-21_15-25-33_TrackWalk »).layer(« _ »Hip).position*1.85208333333333
The only problem is that you’ll not be able to adapt your positions, so you can add the value if your layer like that:
value+(comp(“2017-07-21_15-25-33_TrackWalk »).layer(« _ »Hip).position*1.85208333333333)
The only thing is that you’ll need to change all your positions to 0,0 so it will not do strange staff.
value+(comp("2017-07-21_15-25-33_TrackWalk »).layer(« _ »Hip).position*1.85208333333333)
