Hi,

I' trying to get a delta from a channel. Already tried it with adding in a feedback node, but the output is not really what i want.

So I'm looking for a way to add up the values from one channel frame by frame to get a delta curve at the end.

Any ideas?

use the chf expression. You can try something like:


chf(“../path_to_channel”, $F) - chf(“../path_to_channel”, $F-1)

The slope CHOP will also do that, if you don't mind delving into CHOPs.

Thanks, but I think delta was the wrong expression for what i want, I think its the cumulative. So add up all values from the previous frames to get the sum from frame 0 to now.

all things I've tried lead to an infinite recursion.

Already reading half the day the manual I think i got it now. Seems to be the area of the channel multiplied by the fps or at least 24.

What you are after is the ‘area’ chop.

It accumulates the values of the channel.
