The post-production process is the unsung hero of the movie business.  There's a saying that every film exists as three different movies; the one that's written, the one that's filmed, and the one that's created in the editing room.  Of course, audiences only see the final version, so it's no surprise that the average movie-goer is unaware of how crucial the post-production process really is and how much work goes into it.  If this is true of any movie, it's doubly so on film as massive as Transformers: Age of Extinction.

Michael Bay just released a cool video on his website that depicts his entire post-production on Transformers 4 from the editing room, to voice-overs, to recording the score, all the way to the world premiere.  It's a fascinating inside look into a side of the business we don't often get to see.  Hit the jump to watch.

The video premiered on Michael Bay's official website (via /Film).

I'm not a fan of the Transformers franchise by any stretch of the imagination, but I have a huge amount of respect for the effort and dedication that goes into making a film on that scale.  It's amazing to think how much work we see in this video and it doesn't even include pre-production or the actual filming.  I'm particularly impressed with Bay's involvement in every level of the filmmaking process. You may not like his movies, but you got to admit Michael Bay is a seriously ambitious and hard-working dude.
