Question Creating square video in Vegas Pro 18

Hello everyone

I'm a first time poster, so I'd like to say how glad I am to be among friends and sharing the advice of the wonderful Derek Moran, a calm and reassuring presence in a world of infuriating technologyt...

My problem is that I want to create a square video that consists of a solid colour top and bottom with a letterbox video in the middle.

So which tracks do I need to leave letter-box shaped and which ones 1-1? 

I'm just confused right now. If Derek or any expert on here does 1-1 tuition I would  gladly pay!

All the best 

Tony

Hi Tony

Sorry for the extremely long delay in responding to your message.
I was ill for a long time at the end of 2022 and missed some of the new messages that were posted on the forum.
I have only discovered your message today!

Would you still like some help?

If you need some help, please tell me something first.
Do you intend to output a 1:1 Square Video format or a 16:9 Aspect Ration video with a square in the centre?

Regards
Derek
