matrix run-length compression? help needed!

    May 23 2014 | 1:26 am
    hello, i have posted before about this (and found some posts from other people too) but unfortunately the problem is still unsolved and this does make me slowly freak out - especially since any non-max programmer tells me this should be really really simple.
    the question is: how can i compress a matrix WITHOUT using quicktime? like simple but fast run length encoding on a matrix...
    background: among other stuff i read video as single frame sequences with alpha from a hardrive (5 plane matrixes at half res uyvy+alpha saved as .jxf). these images always cover only a small part of the screen though, so 4/5th of the data is literally "0" - but since i work uncompressed, i need to read in the full data which maxes out my drives. and yes, i did vastly experiment with all flavours of quicktime compression but at least in my specific case quicktime (or hap or vipr) is simply not an option because it's just way too slow.
    please, please, please, can someone shine some light on this? thanks a lot for any help!! k

      noone, really? is that idea so bizarre? i mean, i know one would usually use quicktime for that but fact is: sticking to jxf i get around 20 fps and i think i would easily get 30-40 if i get this problem solved. using quicktime i get 8-15fps.

      sorry for being a pain but: bump. i mean, if this really should be utterly impossible and the point where max hits the wall, can someone who knows please tell me so? then i can at least tell these non-max programmers, they can now start laughing at me... k
