Video Keyboard Alignment Issue (Scale & Position)

This is a fantastic software that I have been using for the past one month to make piano covers. Thanks a ton for creating this app.

This is my issue - I have a 61 key Yamaha keyboard with me using which I'm recording MIDI as well as video. However, I find it very difficult to align my keyboard in video with the one shown in Seemusic app. I have tried cropping, scaling, positioning etc with and without Seemusic app. But I find it impossible to align my keys perfectly with Seemusic keyboard keys.

Is there hope for me to align this in future versions of this app or kindly suggest me a way to solve this problem.

Kindly see the below image. Keyboard in top is my 61 key Yamaha keyboard (coming from my video). Keyboard at bottom is Seemusic's inbuilt keyboard scaled with a value of 1.53 inside Seemusic keyboard options.

Please help me! I love your app.
