Extract Just Dance autodance video

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).

    As an alternate method (if you don't have network connection or prefer swapping SD card), you can use SaveMii to access your save files (thx to @Incure for the idea).

  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 webm video, which is starting with data 1A45DFA3. For me it was located at 0x7D1CC - 512460 in decimal). Optionally you can 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
UPDATE 4: add SaveMii method to access save files
UPDATE 5: modify description to locate webm video data

Hi all,

I'm trying to do the same on PS4 file for Just Dance 2015. To retrieve the files I did a backup of the save data files (via standard PS4 feature).
Now I have the files, however, I'm not able to find any 1A45DFA3
Is the files encrypted by Sony?

Do you have any solution?

Thanks

Yes, they are encrypted. After a fast search I've found this solution (not sure, that it works with current FW saves too):

Hi,
I found the 1A 45 DF A3 exactly at the given location, deleted everything prior to that, I also deleted all the zeroes at the end of the file, changed the extension to webm but it won't play.
Can you help somehow?

I can look into, if you can send me the original decrypted file in private message via (gdrive, mega...).

    yall im torn... ive been hacking away at tales of phantasia GBA (the USA version) and have so many documents of reverse engineering i've done
  • TwoSpikedHands @ TwoSpikedHands:
    I just found out that the EU version is better in literally every way, better sound quality, better lighting, and there's even a patch someone made to make the text look nicer
  • TwoSpikedHands @ TwoSpikedHands:
    Do I restart now using what i've learned on the EU version since it's a better overall experience? or do I continue with the US version since that is what ive been using, and if someone decides to play my hack, it would most likely be that version?
  • Sicklyboy @ Sicklyboy:
    @TwoSpikedHands, I'll preface this with the fact that I know nothing about the game, but, I think it depends on what your goals are. Are you trying to make a definitive version of the game? You may want to refocus your efforts on the EU version then. Or, are you trying to make a better US version? In which case, the only way to make a better US version is to keep on plugging away at that one ;)
  • Sicklyboy @ Sicklyboy:
    I'm not familiar with the technicalities of the differences between the two versions, but I'm wondering if at least some of those differences are things that you could port over to the US version in your patch without having to include copyrighted assets from the EU version
  • TwoSpikedHands @ TwoSpikedHands:
    @Sicklyboy I am wanting to fully change the game and bend it to my will lol. I would like to eventually have the ability to add more characters, enemies, even have a completely different story if i wanted. I already have the ability to change the tilemaps in the US version, so I can basically make my own map and warp to it in game - so I'm pretty far into it!
  • TwoSpikedHands @ TwoSpikedHands:
    I really would like to make a hack that I would enjoy playing, and maybe other people would too. swapping to the EU version would also mean my US friends could not legally play it
  • TwoSpikedHands @ TwoSpikedHands:
    I am definitely considering porting over some of the EU features without using the actual ROM itself, tbh that would probably be the best way to go about it... but i'm sad that the voice acting is so.... not good on the US version. May not be a way around that though
  • TwoSpikedHands @ TwoSpikedHands:
    I appreciate the insight!
  • The Real Jdbye @ The Real Jdbye:
    @TwoSpikedHands just switch, all the knowledge you learned still applies and most of the code and assets should be the same anyway
  • The Real Jdbye @ The Real Jdbye:
    and realistically they wouldn't

    be able to play it legally anyway since they need a ROM and they probably don't have the means to dump it themselves

  • The Real Jdbye @ The Real Jdbye:
    @Karma177 that sd card is 100% faulty so yes, its a bad idea
  • The Real Jdbye @ The Real Jdbye:
    even the slowest non-sdhc sd cards are a few MB/s

    @The Real Jdbye it hasn't given me any error trying to write things on it so I don't really think it's faulty (pasted 40/50gb+ folders and no write errors)
