Dear Jeff,
How about using the "Walking Average" plugin you mention, then only use every 4th image.

Subject: stack averaging
I'd like to average the frames in a stack but all I can find are "walking"
averagers where they will average say frames1-4 then 2-5 etc.. what I'd like to do is take the average of frames 1-4 then 5-8 and so on, so that we can take data that is say at a frame fate of 4 fps and make it look like it was taken at 1 fps (to reduce the noise in our images and because we record things at different frame rates). So essentially if we were doing say 4 frame averaging then a 100 frame stack would turn in to a 25 frame stack where each slice was the average of 4 consecutive frames.
I could write a plugin to do this, but if one exists, or there is a macro I could use can some one point me in the right direction ?
thanks..
-Jeff
