JVC GR-80S : Editing in camcorder exemple

Here is a "slideshow" all done with the camcroder itself like if it was in 90's in few steps :
1 : Recording the audio track thanks to the audio line input.
2 : Inserting video and trying to get some synchro with music
3 : Share with the world... (Well, not really like in 90's :D)
Video insertion of course kill Hi-Fi, only mono linear track can be used for music.
The end is a bit brutal, i didn't really plan anything.
But i was just wondering how cool this capability could have been back in the days :)
