I have an 8-way opteron machine to run some POVRay renders on and it seems
to work well creating frames one at a time. Does there exist some tool
that will allow me to do the following ?
( 1 ) issue 8 povray commands that produce animation frames in
sets. So CPU0 works on frames 1 to 32 and then CPU1 will
work on frames 33 to 64 etc etc. This is done with the
+KC and start and end frame number options easily.
( 2 ) process all frames into an MPEG4 animation file
My objective here is to take a given POV input file and a well described
camera path based on the clock parameter and have an animation all done
by the computer at the back end. I am not interested in seeing frames
unless there is a problem. The only thing I care about is how many
frames in total.
Is there a tool that takes sets of PNG input files and creates MPEG4 ?

The quick & easy answer to question #1 would be add +SF... & +EF... to each
of your commands. You can also use 8 different .ini files:
From section# 3.1.2.1.3 Subsets of Animation Frames:
Subset_Start_Frame=n Set subset starting frame to n
Subset_Start_Frame=0.n Set subset starting frame to n percent
Subset_End_Frame=n Set subset ending frame to n
Subset_End_Frame=0.n Set subset ending frame to n percent
+SF0.n Same as Subset_Start_Frame
+EF0.n Same as Subset_End_Frame

yes .. that generates the actual frame data. I knew that bit.
What is missing is the MPEG4 conversion stage. Does there exist some
tool that will take a slew of frames as input and then output an actual
animation ?
Keep in mind that this all happens on some big backend server.

I use ffmpeg (http://ffmpeg.mplayerhq.hu/) for this task. It is a quite
versatile command line tool for all sorts of video and audio.
