I'm not sure if it's been discussed before, but the Nintendo Video app stores the videos in the SD card, and they seem to be located in
SD:\Nintendo 3DS\0b8ef6742ed57d44d18621aa43ad6206\7e2d00b14760aef4534430320002544d\extdata\00000000\000004aa\00000000
(at least in my card).

there are six files, all 52,016KB, which i think are the actual videos(there are 3 videos in the Nintendo Video app) with an .app extension, but I don't know the file type.
Does anybody know?

Only Nintendo.

It's their own custom proprietary format.

i know where you're thinking of taking this... if it helps, that Puss in Boots 3D trailer had FotoKem emblazoned on its last frame. seems they did the conversion from 3D format to whatever format the Nintendo Video uses.

also, we'll have better luck once the 3D video recorder app comes. we'll be able to record our own videos, which i doubt will be signed, which hackers and video experts can tinker and tear it apart, pinpointing its format. after a while, when the format has been fully identified and replicated by replacing recorded videos with other content not made by the app, then we can start expecting converters to appear. when that happens, prepare to start converting Bluray 3D rips and putting them on the 3DS.

sweet. my dream comes true then. Avatar 3D, on my 3DS. and 3D cornographic films.

Not necessarily. However, all the files stored on the SD card are encrypted, so no one could tell.
My shot is they are simply using the old ActImagine/Mobiclip codec as on DS, but with two video streams (one per eye).

i'm hoping they're just using downsampled 3D formats, like the ones they use on Bluray (MVC). then it'd be just whatever protection scheme the app gets going on, if it has one.

that's what I thought at first, but I'm a noob when it comes to encryption, and only tried with puyotools and the usual Wii formats.

3DS' hardware is not powerful enough to decode H.264 (AVC) video.

They let you take pics off the 3ds which you can view in 2d, so I didn't see why they wouldn't let you with videos.
It would just be silly not to. :P

Well, it is perfectly possible for Nintendo to encrypt all the videos recorded by 3DS with an assymetric crypt.
So, videos could be shared & viewed by everyone, but recorded only using 3DS, so that no one could create a converter and convert regular movies.

well, we'll all know once hackers take a look at the files themselves.

Because we know the exact specs of the 3DS, right?

No, but I'm taking an educated guess.
Usually, H.264 is decoded by GPU. Pica200 has no such option out of the box, and has no programmable pixel shaders to implement it.
When it comes to 3DS' CPU, it is mostly likely 2 x ARM11 268 MHz. This is not enough to decode 800x240 H.264 video stream in realtime.

A guess is still a guess. Besides, Nintendo loves to do "custom" stuff to their hardware.

The resolution of the 3DS is 400x240(x2 for 3D). Just sayin'.
