Just dance videos

[abdz07]

Hello guys, it is my first post. If there are missing information about my question, sorry.

I am too far away video codecs etc. I was trying to backup my xbox 360 autodance videos, i did something wrong. My backup was deleted and recover with some software. And i recovered something and now I can't play that videos.

Firstly, I used MediaInfo and i found out that videos have vp8 codec and auidos have vorbis codec.

Afterwards, I tried ffmpeg and i got the error that;
[matroska,webm @ 00000295bc9dfa80] Format matroska,webm detected only with low score of 1, misdetection possible!
[matroska,webm @ 00000295bc9dfa80] EBML header parsing failed
[in#0 @ 00000295bc9df700] Error opening input: Invalid data found when processing input
Error opening input file C:\ffmpeg\bin\slot_8.webm.
Error opening input files: Invalid data found when processing input
Encoding test failed. CHECK OUTPUT ABOVE

Lastly, I tried the "Disable header removal compression..." with mkvmerge (With that post; https://forum.videohelp.com/threads/341226-Header-stripping) and finally i got output files however it can not play on vlc player and others.

How can i recover the Just Dance videos? That's my GF's childhood videos and I have to find them quickly
