@Yves_BAZIN yes its possible … but only each universe one file. now i will try recording a bit longer and to save the *.out file on the card maybe it will read the file.
By the way, the jerks are always at the same places as the animation. i tried it with resetting the controller.
@Stef_Weicks oki but first try to record longer with the current WiFi program.
@Stef_Weicks that is not an issue a program to merge the files in one can be done
@Yves_BAZIN i tried compteur<5000 with no improvements.
@Stef_Weicks is the issue still at the same place ? Or is it happening more often ?
yes they are still on the same place.
now i tried it with the *.out files… after recording i renamed the file in a savedata.dat and this is what i get…the colors are like in the animations… and i can also imagine a little bit of the animation…
in this pic i did a green filled area

@Yves_BAZIN
and this pic is a scrolling text of “Jinx!” … the animation is also in motion. you can always see some flickers (white red blue )in between … but i think the info would be there…
i recorded only 1 file (universe 1) which is strangely reproduced on all outputs

the white, red, blue flickers are not on the same position … its like they are scrolling very fast trough the screen (from the right to left side).
@Stef_Weicks that is normal ‘cause the read program reads your file as it was an entire frame each time.
But that means that the out files are simply a save of the universes. Hence I should be able to write a simple program to merge the 16 universes into on file that can be readable by the ‘read program’
@Stef_Weicks if there are still on the same place or also recurring with the same period of time
should i record all 16 universes and send the files to you? … if that is so “easy” as you said… would be great! 
they are recurring with the same period of time
@Stef_Weicks can you show me the video ?
I guess I need to set up an Sdcard to one of my esp 32 ‘cause to debug like this I feel a bit blind lol
… i will try to upload a video

@Stef_Weicks I meant the video of the playback of the last recording done with the latest version of the program I sent you with like 5000 frames
ok here you are.

@Stef_Weicks and the video of that playing ?

@Stef_Weicks thank you. What is strange is the half frame read.
In the read program can you replace
Fastledshow32(); with
FastLED.show();
