Challenge 3: What Happens to Proxies During the Final Render — Solution Walkthrough

What actually happens:

Per this chapter's own material, during the actual render process on
the Deliver page, Resolve automatically switches back to using the
original, full-resolution footage rather than the lower-resolution
proxy files that were used for smooth editing on the lower-power
laptop. The proxies played no role in the final render at all — the
render pulls directly from the original source footage.

Why this is the actual mechanism behind Chapter 3's own promise:

Chapter 3 stated that proxies never affect final export quality, but
didn't explain exactly how that worked. This chapter reveals the
concrete mechanism: the swap back to full-resolution footage happens
specifically at render time, on the Deliver page — the proxies were
purely a convenience used during editing, and the render process
itself is where Resolve reconnects to the real, original footage.

Why this means the final video is unaffected by the earlier use of
proxies:

Since the render pulls from the original full-resolution files rather
than the proxies, the exported video's quality reflects the original
footage entirely, regardless of what resolution was used to edit
smoothly on the underpowered laptop — exactly the outcome this course
promised back in Chapter 3, now shown concretely.

WHY THIS WORKS AS AN ANSWER
------------------------------
This exercise directly connects this chapter's own render-time proxy-
swap material back to Chapter 3's own earlier promise, correctly
explaining the concrete mechanism that makes that promise true.
