    In Just Dance after a dance it is possible to save (and share) a short clip (called Autodance, ~20 sec) recorded by the WiiU Gamepad. In theory it is a nice feature, but the only way to access and share the video is through Just Dance TV, which is public for everyone and "Autodance videos may be redistributed by third parties". This is something, which is unacceptable for me, so I tried to find another way.

    1. First step is to locate (and get) your saved Autodance files. To do this you have to access the filesystem on your SD card or external USB drive. I used FTPiiU Everywhere FTP server (thx to @dimok) to locate and copy the files via my FTP client (Total Commander). As I have an external drive the files were located at

      Just Dance 2016 Eur: /storage_usb/usr/save/00050000/101b9800/user/[userid]/JustDance2016/
      Just Dance 2016 USA: /storage_usb/usr/save/00050000/101b9000/user/[userid]/JustDance2016/

      Just Dance 2017 Eur: /storage_usb/usr/save/00050000/101eaa00/user/[userid]/JustDance2017/
      Just Dance 2017 USA: /storage_usb/usr/save/00050000/101eb200/user/[userid]/JustDance2017/

      Just Dance 2018 Eur: /storage_usb/usr/save/00050000/10210c00/user/[userid]/JustDance2018/
      Just Dance 2018 USA: /storage_usb/usr/save/00050000/10211300/user/[userid]/JustDance2018/

      JDSave_0 contains save data (I guess), but JDSave_1 ... are Autodance files (8Mb per file).
      [userid] is different for every user (in my case it was 80000003).

    2. I assumed (and hoped), that the video should be in some common video format, so loaded the file into a hex editor and scammed it. After some header info and a bunch of zeroes I found webm header. From this point it was easy. All you have to do is to truncate the first part of the file (before the actual video data, which is starting at 0x7D1CC - 512460 in decimal) and (optionally) trim blank (zero) data on the end (search for it).

    3. Rename the file to *.webm and load with a compatible video player. Enjoy your private video :)

    UPDATE: checked and the same format has been used in Just Dance 2017 (and maybe in earlier versions, should be confirmed)
    UPDATE 2: add USA paths
    UPDATE 3: the method works for Just Dance 2016 (confirmed), add JD2016 paths

    Dear Admins!

    Is it possible to change the title of the forum to Extract Just Dance autodance video (as the method works for earlier versions too)?

    Thanks!
