Counting pixels

hi there

probably a stupid question but I cant find the node that counts up the total sum of a value (for example changed pixels from trautner)

I need a total value that is getting bigger with every changing pixel

if anybody can tell me that?


+ (Value Spectral) ?

or Integral (Spreads) ?

thnx guys but thats not what I am looking or
I think I have to make myself more clear

the trautner freeframe effect gives a number of changed pixels.
I am searching for a node who counts up all those canged pixels.
I want the changed pixels to influence the speed of a playing movie. the more pixels change, the higher the speed gets.

I need a total number of changed pixels for the map node and a node who couts them to take a position between 0 and 1 in the movie

I will add my patch to this message, maybe you could have a look.

thanx a lot

Perhaps the Queue node can help you to store the value off every frame, and than you can count them up with what Kalle said.

Maar kijk even in je PM, dan kunnen we MSNen of Skypen :D

queue node helps but doesnt do the trick

I have to count up the total value of 1 input, it only has to count up untill eternity, and never count down.

but thnx anyway

mijn pm? personal message? waar kan ik die vinden?

you mean an adder ? bang every frame added and spectral_add the result ?

smallest adder i think.v4p (5.1 kB)

thnx ggml but I dont understand your patch, how does it work?

I think I have to make myself clear one other time.
I have 1 output that gives a lot of values, these values have to be counted up, so if it gives:

in the first second: 2
in the second second: 5
in the third second: 8
etc. etc.

after three second the “counter” must have a sum of: 15

wait, maybe the counter does the job…

it does… a bit, it only counts up with 1, but it has to count up the original value…

hm anybody knows something?

I think this works!

thanx a lot!
