I was just trying to find how I can remove reduce hard drive space while producing a commercial amount of video idea here works but you need to read it and understand that it was done on a phone with long video clips

reduction.py

#to me
#i made this on py droid so ill make a few branches?
#what: is reduction? ok so the goil is to hilight changes in a video stream currently drops the output to a gif
#why: because this ran on my phone the filter of frames was vittal 
#i wantted to record what i was doing in a way that i could review latter 
#I want to make the filter customizable got for now
#this is a demo and it shows the root idea, some numbers need be changed to 
#reduce gitter i want the leading resaloution and trailing resalution to be customizable 
#TODO: add pool max and pool avg and face detection and other fileter like 3d face masks
#i belive with cude i can hash the images faster and fill a matrix of changes
#we maybe able to detect unstable video segments and relative depth
#isolate image segmants and build custom video format 
#plan: before we can add any of the TODO content we need to take a moment to make what we already have a pipeline builder framework
#it will be nice to disbatch frames in a fashion that can latter be parallarized 
#as such we may want to crop compress cross refrance with prior soft max 
#i want to build a batching mechanism with a content disreguard masks
#i want a predictive tool set with the most basic of tools
# i want hooks and a rich set of features!
