French media site "Game One" put together a documentary on Game Music.
They were assisted by a Famitsu staff writer (rolling Uchizawa) who presumably got them quick access to all the composers.

While they are forced to include the obligatory introduction to the 'concept' of game music during the intro, (the first 10 minutes seem like every other Nobuo tribute) it does pick up from there and gets to the good stuff, spending some 1-on-1 time with each of the composers and going over their most popular works.  Overall it turned out quite well.

Part 1: Nobuo Uematsu, Yuzo Koshiro
Part 2: Hitoshi Sakimoto, Nobuyoshi Sano, Akira Yamaoka
Part 3: Masaya Matsuura (who has WALLS of vintage Analog gear in his studio)

It's up on YouTube, not sure if it ever got broadcast on TV or screened anywhere other than online though.

After some searching it seems that Game One has quite a large staff (being part of the MTV Entertainment Group) and has made other documentaries such as "History of Shooting Games" "History of Fighting Games", Horror Games, etc...  View here for their background.

It definitely got broadcast on TV, since Game One is a French channel dedicated to video games. I was able to watch this documentary when it first aired, a few years ago (I think it was some time before the release of FFXII). Actually, the documentaries were not made by Game One, but by Pocket Shami.

If some parts of the documentary are of interest to any of you, I can translate what the narrator or the composers say.

Thanks for the clarification, and yes I should be giving credit to Pocket Shami for the production.

One step better? Volunteer your services to Game One to help develop an English language version (either dub or subtitled).

This looks like a great series, but I don't speak French so...

Err, no. I'm not very good at translating my own language to another. I definitely prefer the contrary, and even worked on video game translations. This is usually a lot of fun!

Well, here is my translation for the VGM documentary: http://vgmdb.net/forums/showpost.php?p=5696&postcount=5

Thanks for your time for translating. Don't worry, the english is fine!

Sakimoto's comments about the pressures of the job are interesting: How the job needs to sell games in order to survive, not pushing too many "weird sounds" at the gamer, how mimicking other people's styles can be tormenting, and needing to define your own style.

Sano laments the sales numbers downsliding from 10,000 to 2,000: "Frankly, you can be very happy if you sell 5,000."

Nice to hear Koshiro describing themselves as "game freaks", and it'd probably be fun to hang out playing games with Uchizawa too.
