Quick Tip help: How to pan 2nd image while using Image wipe?

Hey all,

Wondering if someone can help me with a quick tip. I was watching this video:

and at 13:26 he pan's the 2nd image in the image wipe on the color tab. I wasn't sure how he was able to do that?

Can anyone help and tell me how to set my file up so I can do that in the future when shot matching?

Thanks!
Spencer

Maybe he used the Reference Sizing?

@xunile - That works perfectly - I bet that is how he did it. So easy thank you. I think he uses a mini blackmagic color panel so getting to that area is easy and no mouse. I don't have one, yet, and I'm still learning. Again thank you for the help!
