CPU speed

[willster2k]

I know that there has been comparisons between CPU's over the months, I have a duron 900, 512Mb RAM PC133 :( , and typically get a speed of 0.75 with CCE 2.50 using the following avisynth script

---AVS Begin---
LoadPlugin("d:\DVD2SV~4\MPEG2Dec\mpeg2dec.dll")
mpeg2source("G:\DVD2SVCD\DVD2AV~1.D2V")
BicubicResize(480,576,0,0.60)
ResampleAudio(44100)
----AVS End----

What speed increase would a 1.4G Thunderbird or 1500+ have as this would max out my board without changing anything else, or how about the fastest chips ?
Before anyone says to read the previous posts, it would be nice just to try the basic script leave it run for 10 mins to get up to speed and just post the speed you get, particularly if you have an AMD system. BTW I have a Soltek motherboard and it is not overclocked... so I could get more juice out of it if I wanted to....
Thanks

Upping to a TBird or an XP chip would increase your speeds dramatically, probably more than you would expect. And although it's a bit risky as far as CCE stability, you should overlock a little too so you can get the best increase. Make sure you have proper cooling and power though :)

Hi willster2k,

I myself own a 1.2 GHz Duron with 256 MB PC133 CL2 Infineon SDRAM and get usually about 0.80-0.90 with BicubicResize and PAL movies - and 0.90-1.00 when tweaking the AviSynth script by cropping the source to replace the TV overscan area with black borders and cut off the top and bottom borders before the resize to add them later again.

I believe the speed increase for you would not be so dramatic as the main bottleneck will still be the PC133 SDRAM memory bandwith for the fast CPUs. DDR-RAMs with KT266/A chipsets have more than the doubled up bandwith and this is the real speed increasing factor in video encoding. So I guess you can reach 1.2-1.3 max with this default script on a 1.4 GHz T-Bird.

Just a guess though,
Gerti

[willster2k]

thanks ! I guess I'll save my pennies for a while longer until there is 3Ghz chips out...... :)

FYI I have a duron 1200 overclocked at 1266 (133*9.5) and i get 1.40 with simpleresize (win2000).
my brother with a duron 1000 gets 1.00(simpleresize and w98) so the 40% diff should be due to both the megahertz gap AND the different bus speed (133 vs 100).

I've never tried bicubic resize.

[Labersack]

The biggest difference would be you SimpleResize. Gerti uses Bicubic, that's a big difference in speed, just try it yourself with one movie and compare it with your SimpleResize-speed.

of course it is.
my post was to stress the difference between a 1000 and a 1200 duron processor with different bus speed (overclocked).
maybe wilster could find it useful :-)

[gerti67]

Hi Cidici,

of course you're right and is commonly known that using a higher frontside bus speed is better than just overclocking the CPU by a multiplier setting only. But my old KT133 mainboard doesn't support 133MHz FSB for the CPU so this was never an option for me :(.

But usually you're overclocking the memory interface also with this method and this gives the real kick in encoding speed with those old SDRAMs. I usually reach 1.2 CCE realtime speed without overclocking my CPU/memory when using SimpleResize and doing PAL movies.

Are you doing PAL movies too? I only ask because if you're doing NTSC movies you'll have an extra speed increase because of less rows to be reszised for NTSC as NTSC is 720x480 and PAL 720x576 - just in case you didn't consider this.

And I guess you have to use the CRC patch right? As the CCE is very picky about overclocked CPU/memory settings and I don't feel vry good knowing there might be something slightly wrong then.

Greetz,
Gerti

-actually my system is DDR based (KT266A) so the memory is working at a rightful frequency (i suppose in this kind
of mobo the FSB is separated from the Memory Bus so they can work at different speeds)

-im doing PAL movies too, so probably the 20% between our performances is caused by the different bus & memory speed (u know, DDR are better than SDRAM and kt266a is better than kt133...i hope :D))

-no CRC patch, i had only one problem with CCE (complaining about checksum error) with a "making of" and prolly it was due to a wrong rip with smartripper (now i use vstrip inside dvd2svcd ;-))

[Bigbucks1959]

I am sorry...is bicubic faster or simple faster..

[UltimateDBZ]

SimpleResize is much faster, about 20% usually.

[sehh]

Hello, just for comparison, my speed is: 2.2

(CCE 2.50, simpleresize,plus some other filter i forget, mpeg2dec2.dll)

I'm running on two AthlonMP 1.2ghz, system has 768mb PC2100 DDR266 reg,
running on Adaptec 29160 64bit SCSI, and two IBM Ultrastar U160 drives.

My problem is that almost ALL the applications that DVD2SVCD uses are
not SMP friendly, so they only use one CPU. That means that my 2.2 speed
is based on ONLY ONE CPU, since my CPU usage is only 50% while CCE is
running :(

That ofcourse allows me to encode two movies at the same time, one on
each CPU, on different SCSI harddrives, and the 768mb ram are enough.
Usualy CCE uses about 170 megs of ram on a 3 hour movie.

Maybe one day CCE and Anisynth will be able SMP friendly, and i'll
be able to see higher speeds (4.0?).

[murattttt]

First of all, thanks for such a good handy program that enables us to make excellent versatile copies of our works ( To ddogg, Dividee, shh, DSPguru, doom9 and of course dvd2svcd ).
I have been reading these forums long before I had a computer of my own and just read and read. No practice ground had I found until recently I built up my own tiny little system. That is
Athlon xp 1800+
256 MB DDR Ram
Asus KT 266 A
Ati Radeon VE 64 MB
Seagate Barrcauda 60 GB 7200 rpm Ide
Quantum 30 GB 7200 rpm Ide
To my surprise I only got a realtime speed of 0.990 at the highest with this built while encoding a NTSC dics with simple resize and temporal smoother 2,1.
What speed should I really get and what place am I doing wrong here?
Thanks

[gerti67]

@Cidici:

Oh, seems I mixed up some facts ;) I assumed you were using SDRAMs - but now that you say you're using DDR RAMs with a KT266A chipset mobo your numbers are no suprise to me anymore (also the fact that you don't need the CRC patch then).

Just check your memory bandwith with some bench tools like Sandra2002 and compare them to SDRAM based KT133 chipsets - it's awesome. And that is your real performance gain as video encoding is very demanding concerning memory bandwith.

Of course the RAM-type is very important, but i wanted to stress the difference between my pc (duron 1200@1266 with 133mhz bus) and my brother's pc (duron 1000 with 100mhz)

the 40% gap is quite amazing , as i've already wrote, probably it's 26% for the cpu speed and 15% for the bus, so maybe someone using duron 1000 or 1200 with a kt266/kt266a system could think about turning off the block on the cpu and change the bus_speed*multiplier to 133*7,5 or 133*9 instead of 100*10 and 100*12

of course this stuff doesnt not apply to your kt133 system, gerti :)

[mrbass]

@murattttt...you are using temporal smoother so yes your cce rt speed sounds correct 40% reduction.

Temporal Smoother (slows encoding down by about 40%)
SmartDeinterlace (slows encoding speed by about 40%)
BlendFields slows (encoding speed by about 10%)
SeparateFields/SelectEvery (PAL) (slows encoding speed by about 15%)
VerticalReduceBy2 (PAL) (slows encoding speed by about 20%)
Telecide (PAL) (slows encoding speed by about 25%)
PAL 480x576 takes longer to encode than NTSC 480x480

[Buggerlugs]

I`m running XP1800+ (1.55ghz),KT266A,512mb crucial pc2100,Geforce2pro,seagate baracuda IV 40gb. Encoding a PAL dvd to svcd with the following settings for my first attempt which i started at 5pm gmt today and is still going now at 2:33am!

Telecide()
SimpleResize(480,432)
AddBorders(0,72,0,72)
ResampleAudio(44100)

I get a speed of 1.041, which means its going to be at it for 10 hours! surely thats way wrong for a pc like mine???

Just as a matter of interest is there a routine to follow to produce the fastest encoding time, because surely regardless of time it takes this programs bound to produce an excellent end product isn`t it?

Does the cinema craft encoder use any of the AMD cpu extentions or is it primarily designed for intel chips?

What would make the most difference to get it encoding faster it dvd2svcd`s settings?

Would me getting another 512mb of ram (putting it upto 1gb) make it encode twice as fast?

Is it just me, or is it miles faster encoding a NTSC movie than a PAL movie, cos it seems alot longer than 20% for pal encoding time?

[Cidici]

@buggerlugs

imho your speed is *too* slow, i've never tried telecide BUT if the 25% reduction mrbass reported is right, there's something wrong, because without telecide you wold get 1.25-1.30 speed, that is slower than my duron running at 1266 with simpleresize)

- i think CCE should use some SSE routines, so amd cpus should perform well too

- i dont think 512mb more will help you, i have only 256MB

probably it would help you to set in dvd2svcd the process priority to HIGH.
If this change doesnt help you, maybe there's something *very* wrong in your bios settings, but i cant guess what

oh, i encode PAL movies too, so this is not a cause for the difference of encoding speed

[mrbass]

he's doing PAL not NTSC and for all we know it's 4:3...seems normal speed to me considering 25% telecide and another hit using PAL.

[Buggerlugs]

I`m sure its too slow. I`m also sure my bios settings haven`t got anything to do with it, they are tweaked to perfection, so much so my sandra benchmarks are KT333 levels.

I think its more to do with the KT266A chipset and the cinema craft encoder, either that or some setting in DVD2SVCD that i`ve missed, because muratttt with a setup similar to mine is experiencing a similar slow speed.

I`m not complaining about the end result, its bloody superb! Certainly kicks DivX in the teeth! But if i could get the encoding time down closer to 5 hours instead of 10 i`m sure my harddisk would thank me in the long term, and i`d be able to get some sleep too!

What sort of speed should I be looking at? more around 1.5 to 2.0?

I have a KT266A too, maybe u need a new via 4in1 driver ? really dont know.
i think your target speed should be the one u suggest.

PS i own a chieftec case too (black) :-))

maybe it's win XP ? i use win2000

[Buggerlugs]

Kewl, nice cases arn`t they! if a touch noisy!

I`ve never used the 4-in-1 via drivers with my windows xp because i`ve heard so many horror stories about how they can cock up your pc to the extent you need to reformat.

Are the new via-4-in-1`s really required with windows xp? I was under the impression the only thing it updated was the agp driver anyway?

Anyone else think its worth while giving em a go?

[manono]

Buggerlugs-

If you don't need Decomb's deinterlacer (and you probably will if doing anime), then you might try Telecide(Post=False). That will give you back some of your speed.

And I'd use the VIA 4-in-1's if I were you.

[Buggerlugs]

actually i did, all i used was telecide and smart resize. Dunno really if i needed to use telecide, as it was pal dvd but i thought what the hell. Speed 1.04 isn`t too dapper though is it.

[manono]

Hi-

From what I understand, most PAL releases don't need Telecide at all, in spite of what DVD2AVI says. Easy enough to find out, though. Make a .d2v in DVD2AVI with no Field Operation, open it up in GKnot, and then step through some frames in some motion sequences of the movie. If you don't see any interlacing, then you don't need Decomb's Telecide.

If all you want is the deinterlacer for some frames, then you can just use FieldDeinterlace()

[Cidici]

i suppose that telecide is needed only for australian pal movies.


i think via4in1 is necessary for a good-performing-amd-system (btw i've not installed a so recent version, it's the one i found when i bought this pc at the beginning of the current year)


ps what do u mean with "smart resize" ? you mean "simple resize" isnt it ?

[vivaatloni]

OK, I read this thread and I am a little confused. I was planning to replace my duron 700 chip with an athlon xp 1800+ on my abit Kt7a board with 133 mhz bus & ram.
But from this topic I am drawing the conclusion that it won't be much of a speed increase!

Please correct me if I am wrong.

[switu]

@ vivaatloni
you're wrong, your speed will increase with the preformance as well.
My provious cpu was Athlon 900 40 gb hd and 512 mb and I was getting max .7-8, now I have Xp 1800 and I'm getting anywhere from 1.2- 1.88
My max speed was 1.9 when encoding avi2svcd
look at this picture link below:
http://members.rogers.com/mega5/speed.gif

cheers

[Buggerlugs]

And what settings did u use to get that high speed exactly??

[switu]

@Buggerlugs

it was done with dvd2svcd and this my Avs script I have used:

LoadPlugin("C:\PROGRA~1\DVD2SVCD\TemporalSofner\TemporalSoften2.dll")
LoadPlugin("C:\PROGRA~1\DVD2SVCD\Unfilter\UnFilter.dll")
LoadPlugin("C:\PROGRA~1\DVD2SVCD\MPEG2Dec\mpeg2dec.dll")
AVISource("C:\PROGRA~1\DVD2SVCD\Movie\test.avi")
ConvertToYUY2()
Unfilter(25,25)
BicubicResize(480,284,0,0.75)
TemporalSoften2(1,5,25)
AddBorders(0,98,0,98)
ResampleAudio(44100)

Remember, I was encoding avi2svcd , when encoding dvd2svcd my speed drops down to anywhere from 1.2 - 1.4

Xp 1800, 60 hd, 512 Mb

P.s.
@Buggerlugs, try to use Unfilter instead of "Sherpen and Temporal smother" this will kick your speed up a lot.
I use TemporalSoftner2 and Unfilter as you can see .
cheers

[Buggerlugs]

hmm......my dvd2svcd does not have the TemporalSoftner2 and Unfilter folders with the dll`s in it like yours does.

So where do i get them from and how exactly do I put them to use?

[switu]

@Buggerlugs,
My dvd2svcd doesn't have those options too, but you can edit your AVS script in Frameserver Tab by checking " Edit as part of Video Encoding" as long you have those filters downloaded and installed.
Here we go, both filters:
Unfilter,Temporalsonfner (http://members.rogers.com/e-commerce/bothfilters.rar)
MOre about those filters check Doom9's forum-Avisynth
