Watch Chip and Joanna Gaines show off their original Magnolia store in their 2012 casting tape for 'Fixer Upper'

• Chip and Joanna Gaines' Magnolia Network makes its debut on cable on Wednesday.
• The couple released their original "Fixer Upper" casting tape from 2012 to celebrate the debut.

Chip and Joanna Gaines took a trip down memory lane with never-before-seen footage of their "Fixer Upper" audition.

The "Fixer Upper: Welcome Home" stars are making their return to cable on Wednesday with the official launch of the Magnolia Network.

The new channel combines the network's original shows with series from the pre-existing DIY network, which will be rebranded as part of the Magnolia Network.

To celebrate the launch, the couple posted their "Fixer Upper" casting tape from 2012 to YouTube, sharing how their Magnolia empire began with the public for the first time.

In the video, Chip and Joanna introduce their home-flipping company Magnolia Homes, and give a tour of one of their projects.

The professional dynamic between the couple that fans know and love is clear from the video, with Chip chatting optimistically about the renovations they have planned while Joanna approaches the project with a more grounded approach.

The Gaineses also give a tour of their original Magnolia store in the video, laying the groundwork for their ultimate transformation of the entire city of Waco, Texas.

Although a lot has changed for the couple since they filmed that casting tape a decade ago, their playful energy together will be familiar to any "Fixer Upper" fan.

The Magnolia Network will launch at 9 p.m. ET with the first episode of "Fixer Upper: Welcome Home."
