Another solution which I have used in the past, if you want to keep the
raw source frames, is to shove them off to tape as they appear. For
example, I have used a script something like this which runs in the
background during rendering:
num=1
while [ $num -le 500 ] # or however many frames you have
do
frame=$(printf "frame.%04ld" num) # frame.0000 format
while [ ! -f $frame ] do; sleep 15; done # wait for it to appear
tar -cf tape:app $frame && rm $frame # move frame to tape
inc num
done
That way, you can later batch process the frames from tape (use tape:nr
as the filename), and you get to keep your 24 bit source material also.
The above script is for sksh (ksh clone, by yours truely, available on
aminet) but you can certainly come up with a simple ARexx or Amiga shell
equivalent. The script takes very little CPU time except for what is
neccessary to copy the files to tape, which isn't much.
(Obviously this only works if you have a tape backup. But you can get 4
gigabytes of off-line storage for $850/drive and $12/media these days,
which is just fantastic for things like this. The first 4 gig costs a
lot, but the second 4 gig is 12 bucks).
