I checked out some more clips... it seems very interesting.
The intro and some other scenes have more black bars than most scenes.
Which means if I keep 704x360 the AR is good, but you miss some pixels, but you wont see blackbars coming and going.
if I change it to 704x384, the AR stays the same, but the video has a bit more pixels and you see the blackbars coming and going which could be annoying.
not sure why they choose to have different aspect ratios in the movie.
here are 3 examples:
original picture 704x480 letterboxed
704x384 no black borders and other scenes miss pixels.. this is no good.
704x384 with occasionally blackborders, this I could do
704x360 no black borders, but sometimes a slightly pixel cut, this is what I am doing at the moment and seems less annoying
Although the majority might have more pixels, so I could do it, but you must realize the occasionally black bars
