Background: Although I might not be the first to come up with this idea, I have not seen others do it yet. I came up with the idea of doing anamorphic 1080p -> 720p conversions similar to DVDs. Only this time, instead of 16:9 to 4:3, it would be 2.35:1 or 2.4:1 to 16:9. Example: Fellowship of the Rings BluRay appears to be in 2.4:1 ratio resulting in a 1920x800 resolution when the black bars are cropped. Instead of doing a straight scale-down to 1280x528, I decided to utilise every pixel the ATV is capable of pushing. I used Handbrake to convert the 1920x800 to 1280x720 anamorphic resulting in 1728x720 displayed pixels instead of 1280x528. Those of you who understand anamorphic will be fine with getting this. For those who don't, the movie is encoded to 1280x720 resolution, the Apple TV maximum. Since it's in a different aspect ratio than the original, the picture would be squashed. So, like widescreen DVDs, to play it back properly, the system would stretch the image resulting in 1728x720 displayed resolution. iTunes, Quicktime, iPad, iPhone and Apple TV all understand the anamorphic coding and stretch it out properly and play it back properly. That's not a problem at all. Question: My question is: What benefit will I get out of it on an Apple TV? Sure, if I watch it on my FullHD display on my Mac, I get all the pixels to use. But what about the Apple TV? I don't have a FullHD TV to test it out. I know the Apple TV is limited to playing back 720p files. But I do know that the ATV can output 1080p. Even the 1st gen one. So, how would the movie in the example playback on an Apple TV hooked to a FullHD display with an output of 1080p? Will it: a) Stretch it and scale it to 1280x528 and then send it to the TV as such? b) Send the movie to to the TV as is and the TV then stretch it to get the maximum potential of the file? I don't even know how the Apple TV operates in 1080p mode. Does it upscale 720p to 1080p? If so, will it: c) Stretch it and scale it to 1280x528, upscale to 1080p and then send it to the TV? d) Stretch it to 1728x720, upscale to 1080p and then send it to the TV? Thanks for any input.
