Both players resources can be displayed in real-time, no video editing required. Just like Commander names and stats(infantry killed, vehicles killed, infantry lost etc. you get the point) in the screenshot at the bottom of this post.
Only limitation is the hard coded font for drawing text which is quite small. Only the text color can be adjusted. It can be placed anywhere in the screen though.
I could try drawing other players resources to the screen just like in the youtube video linked at first post. It would be real-time, of course.
Drawing commander abilities would be a lot harder though. Displaying commander name is easy.
Here's a screenshot from mod I've been working on:

All the stats are displayed in real-time while watching the replay.
Wow, makes me hopeful that one day we could have nice things
But yeah, right now the only option we have is to edit that stuff in.
