DV AVI files are what you get when you capture FireWire/1394
digital video from a Mini-DV camcorder into a computer.
MPEG2 is the format you need when you want to record DVDs.
On an Athlon XP 1800+ with PC2100 memory and fast hard drives
(which btw are NOT the bottleneck), it takes approximatelly
4 to 6 hours to convert 1 hour of video from DV to MPEG2.
Please research the performance and cost of the following
hardware when used for the same task:
1. The Matrox RTX.100 card, which sells for $1000 :-(.
2. A dual-processor Athlon MP based system, fastest clock available.
3. A dual-processor Xeon based system, fastest clock available.
4. An Athlon 64 3400+ system. Dual-processor also if it exists.
5. A Pentium 4 Hyperthreading system, fastest clock available.
6. One of the ADSTech Pyro DV or Pinnacle boards, if appropriate
(I don't get the impression that any of the low-end DVE hardware
has accelaration features).
7. Any creative solutions that you might have. e.g. renting time
on a supercomputer, or a low-cost Linux Cluster or something :-) |

You can consider a Power Mac G5 dual 2 GHz system with DVD Studio Pro.
With the G5 processor's AltiVec instruction set and DVD Studio Pro
being optimized for it, you can do the conversion fairly quickly.
LINKS:
http://www.apple.com/powermac/
http://www.apple.com/dvdstudiopro/
http://www.apple.com/dvdstudiopro/compressor.html
PERFORMANCE:
According to http://www.apple.com/powermac/performance/, the Power Mac
G5 encoded a DV file and turned it into MPEG-2 more than twice as fast
as a dual 3.2 GHz Xeon. DVD Studio Pro with Compressor (Compressor is
a free download) was used.
PRICE:
The Power Mac costs USD$2999.
DVD Studio Pro costs USD$499.

That's good. It sounds like the dual-G5 could do about 45 FPS
(1.5x real-time).
But what about the dedicated cards like Matrox, Pinnacle, and ADSTech's ?
Can $1000 worth of specialized hardware beat what's effectively a $3500
general supercomputer?
Please note I've also posted a narrower version of this question:

My post above was more of a comment, but I posted it as a
Clarification to get your attention.
My instinct says that hardware cards are faster. But I don't know;
dual G5's are pretty fast, too!
I don't have experience in this field (other than with Macs
specifically) so other researchers should answer this question! ;-)

ssparks827 and byrdhouse,
I looked into the Canopus DV Storm... apparently it is not as
good a deal as the Matrox RTX.100:

What do you think? Is the comparison biased?
supermacman thanks for letting me know about the dual-G5, I had not
realized the high-end macs were such powerful machines! Too bad they're
a bit out of my budget.
