user21776: One of those videos lower resolution, another one is higher
ffplay.exe -i [PATHTOFILE][org] -i[PATHTOFILE][enc];\
[org][enc]blend=all_mode=difference"enter code here

but i got error 
    No such filter: [filename1][org][filename2][enc];
[org][enc]blend=all_mode=difference: Invalid argument

I Just want to compare my videos utilizing FFPLAY with many inputs to save some memory.

user1871: ffplay is designed to play a single input. So, a workaround is needed.
ffplay -f lavfi "movie=org[a];movie=enc[b];[a][b]blend=all_mode=difference"

A filtergraph is created and movie source filters used to open the files, then blended.
