Which would almost certainly have required different actors, given the 25 years since the original release, and I imagine that would have cause a huge uproar in addition to being fairly expensive.
That was probably well out of scope of what they originally planned for as C&C had quite a lot of pre and post mission videos.
Out of scope, sure, but I agree that that option prevents "extract old video from the production version and try to upscale it automatically" from qualifying as "the best they could do".
