I left the block limit set very high while messing around to see what effect
it had, if any, on image quality. I hadn't noticed any difference so I left
it. I was working on deadline for a local TV spot. We had to call DPS to find
out why our animations were not playing. They would start off fine but when
the images began to get complicated, ie. dramatic light changes, complicated
effects, lots of motion etc.. the animation images turned to many colored
squares and other corrupted looking junk. When we manualy scrolled through the
ani the individual images seemed fine. Upon closer inspection the individual
fields were corrupted looking to verying degrees.
DPS asked me to check my block limit setting and sighed. I checked, told him,
he said set them somewhere around 220 – 240 for the micropolis 2217. I do not
recall the exact explanation but it went something like this – the drive will
record all the information that the limit setting will allow. BUT it cannot
manage that much information fast enough when playing the animation back, at
least on my Gateway 486-66. I recopied the tga's to the PAR with the BLS set
to 240 and have had no problems since thank you.
