System speed relative to encoding speed

[mrtristan]

For those of you with newer systems, have you noticed a decrease in encoding times, or does software like Tmpgenc run at the same speed?

I'm pricing out a new AMD XP based system, partially to be able to encode at faster rates. I'm satisfied with avi file encoding, but it just takes too long, when I render the final project in Tmpgenc.

My current system is based on a 1.1ghz AMD Thunderbird, with 1024MB of RAM. It's not slow by any means, but I could easily be happy with something faster.

If all other factors remain equal (source material, encoding software, encoder settings, etc) more CPU muscle results in faster encoding. Notice that when you run an encoder (i.e. tmpgenc) at highest priority, your CPU usage is pegged at 99-100%.

I just upgraded to a P4 running at 1.5GHz. I like the pentium because of its fast processing of math, which is 100% of what encoding is.

Running Tmpgenc, I can do 1 hour VCD encoding in 50 minutes, and 1 hour of SVCD encoding in 1 hour and 45 minutes. I don't think any AMD processor can beat that speed performance. With a 2.2GHz CPU, it would shave of even more time.

If I can beat your speed??

YES

Try 2xMP1900 AMD in TMPGEnc. I encode SVCD faster than realtime, with high settings.

Yes, multiple processors will do the trick.

Mirror_Image,

How do you set TMPGEnc to be the highest priority (I'm guessing we're talking about threads, right)?


skittelsen,

50 minutes? I have a P4 2.0GHz and it still takes me about 2 hours for a good 45-minute encode. Are you not using any filters at all? Do you frameserve or not? How is my processing time so much larger than yours? Can you give me some specifics on your encoding process?


Thanks!!

I have an AMD 1700+, with the super cheap ecsk7s5a mobo. I laso have 128 megs of DDR ram running on winxp Pro. The entire dvd2svcd, encoding process, takes me 5 hours. From ripping, to the 2-pass tmpgenc vbr encode. I get great results, and couldnt ask for more considering my last system threatened me with 21 hours, at a low rate of constant quality (cq).

option...task priority

[OptimusPrime22]

So what about the encoding process entirely? The moment TMPEG is started and it stops. I heard that dual systems make it faster even with filters on because the second cpu is handling the filter process. Any thoughts would be helpful. Thanks.

No, dual-CPU systems run poorly with filters on, probably because the second CPU is handlking the filter process. I ran some tests on a dual 866 MHZ P3. With no filters, encoding speed was about 1.95 times faster with dual CPUs compared to the same encode on a single CPU. With the noise reduction filter on, the dual CPU encode was about 1.3 times faster than the same encode with a single CPU.

Question -- mirror_image
or whomever!

When setting the task priority there is several options in the pulldown menu. ie(normal when active, high when idle, higest when inactive etc..), Im assuming that if Im setting it a night before bed I should set it to highest priority when inactive> This correct?
