I've been having trouble finding a release outlet I'm comfortable with lately. A lot of places formerly safe or that welcomed edits no longer do.
Also, I held off because I thought there might have been a last minute tweak coming. I was looking at doing Deathly Hallows and it made me rethink some things.
I don't know about anyone else, but in the DH films, when my TV is set to it's most accurate movie viewing mode, there are scenes that are almost completely black.
While I will be making dynamically brightened versions of the DH films (mostly because I think the director is a hack to make them so dark), I've determined that although HPB is pretty damn dark at times, it never gets as bad as the two DH flicks.
I was worried that if I brightened Deathly Hallows they'd be brighter than HBP which wouldn't be right either. I think I've found a good balance.
I'm also pretty convinced extending the DH films is a waste of time. Most of the deleted scenes have unfinished effects, are lacking context to know what is going on, are really boring, or just don't feel necessary in these already unnecessarily strectched films.
There might be 1 or 2 useful scenes to each movie, and that's just not enough to go to the effort.
