DUAL PROCESSORS CAPTURING

[jakecb]

ANYONE AWARE OF SOFTWARE AVAILABLE FOR DUAL PROCESSOR
CAPTURING. I USE TMPEGNC TO CONVERT AND IT HAS DUAL
PROCESSOR CAPABILITY. THANKS IN ADVANCE.

Just out of curiosity, why do you want to use dual processors during capture?

[flaninacupboard]

realtime divx capture would be my guess. although the point stands, do you require dual processig for that?

Premiere is also multi-threaded to take advantage of dual-processor computers. However, even on a dual processor computer, you can't run other tasks while capturing. I have 2 dual processor PIII computers and the daul processor configuration doesn't do much to enhance the capture process...where the dual processor does come in handy is for encoding, rendering and mult-tasking...as you mentioned earlier, TMPGenc, which is also multi-threaded to take advantage of dual-processor computers, will render faster with two processors than with 1 processor of equal or slightly greater speed....as far as multi-tasking goes, if you are encoding or rendering using ona dual-processor computer using a program that doesn't take advantage of multiple-processors, you can use other programs or surf the interent with no slow-down...because I'm always multi-tasking, if I had a certain amount of money to spend on a computer, I would build a dual-processor computer with slightly slower processors over a single-processor computer with one faster CPU...

I ALREADY HAVE DUAL PROCESSOR I JUST CURIOUS IF THE CAPTURE
PROCESS COULD BE ACCELERATED, APPARENTLY THIS IS NOT POSSIBLE. THANKS FOR THE INFO.

jakecb there are a few capture card that can take advantage of multi-threaded but there not low end capture cards so yes it possible but real q that come to mind is how much do you want spent?.

the capture process itself is typicly a very low load on the cpu,
it's the encoding part that sucks cpu cycles.

If your goal is to capture in realtime to mpeg2,
you can just get a card that supports (in hardware)
compression-- that will put very little additional load on
your cpu.

If your goal is to do more than one thing while capturing,
a second hard drive will help more than a secong cpu.
make sure you put the second drive on a different ide chain.

if you're piping your output directly into tmpg,
you can get better encoding performance by enableing
multi-threading if you have a second cpu. However, since
tmpg is now crushing both of your cps, doing something else
while encoding is not advisable.

If you're not using a multi-threaded encoder, you can still get a
little milage out of a second cpu by frameserving from vdub--
where one cp will handle the vdub/avisynth and the other will
handle the encoder. That's not an even distribution of work though
(since vdub isn't really cpu intensive for capturing) so don't
expect much gain (I'd look for on the order of less than 1 fps)
