What do you need for Huffyuv 704x480 capture?

[Phire]

Just wondering what you needed for this, I can pull off 352x480 with no frames dropped. Only got about 26fps with my 488mhz Celeron and Maxtor 40gb DMA66. So my question is, is a faster cpu needed or a faster hard drive? or both? I have all the pieces for my Tbird 1ghz computer except for the cpu fan, that's the only thing im waiting on to come in the mail, but im not changing any of the hard drives.

I think you will need a raid. I'm running a 60 gig with two IBM 30gig 75GXPs, on a Tbird 750 to one gig depending on temperment. The capture quality is worth it though, it looks much better post render than mjpeg.

Ooh, don't - I'm drooling.

After months of reading about everyone else making good with Huffy, I've just taken the plunge and built a new system to have a go myself. Currently I've just commissioned the basic system (Asus A7V, Fujitsu 8.4Gb boot drive, Samsung CDRW, Marvel G200, PCI modem) and am busy getting all of the basic functions sorted before step 2. I've got 2 IBM GX75 30Gb HDs and a Fasttrak100 sitting in the corner begging to be installed, but they'll have to wait until I've got everything else locked down first.

Just to let you guys know, HuffYUV is very doable on 5400 rpm drives without any RAIDing. I frequently capture 640x480 HuffYUV onto my multimounted partition (made up of a 7200 rpm UW SCSI IBM, a 5400 RPM 20gb IDE IBM, and a 7200 rpm RPM 20gb IDE IBM). I'm not running any striping at all, I just extended the partition over the drives, and I don't get a lost frame at all on my dual Celeron 366 overclocked to ~515 rig. It worked fine also under Win98 capturing 704x480 directly to the 5400 RPM IDE. The datarates that HuffYUV generates are in the neighborhood of 10 megs/sec or less. (in the worst case 12 megs/sec) Most semi-modern 5400 rpm drives should handle that without a hitch. Phire, I would suggest upgrading your CPU since I think that could be your limiting factor. When in Win98 the CPU meter is always very high when I capture HuffYUV (when I'm stuck with a single processor) note: I'm assuming the 40 gb Maxtor is on the secondary channel, and is not either the slave to the boot drive, or the boot drive itself.

TI,

You're gonna have so much @#$%%*& phun with those 75GXP drives on the FT100. My main system has four 60g models in two 120g arrays. DAMNFAST....

Doc,

Looking forward to it, but am a bit pissed that my new rig still won't cut the mustard with the e450TV - The Matrox site gives a minimum of 600Mhz but doesn't give a table of processor speed vs frame size.

O/Cing the Tbird isn't on the cards since it is locked to 800Mhz and I'm NOT about to get my soldering iron out.

Cheers

What soldering iron? Just take a simple charcoal-pencil and connect the L1 bridges on your TBird - there you go: 1GHz should be possible.


I'd definitely oc the TBird, I run my Duron800@1026 (1.80V core) and CPU usage is quite high capturing 768x576x32@25fps with the PicVideo MJPEG codec - but I don't drop frames.
HuffYUV has lower CPU-usage, so the TBird@800 should've no problems to manage it in 704x480@30fps, considering that the NTSC data-rate is slightly lower than PAL.


EDIT: This is with captures done on a Hauppauge WinTV and in Win2k, dunno how it is with the G450eTV or in Win98/ME...

Hi Chris,

Here are a few links to get you started:

I have my 850 T-bird up at 1Ghz+ and haven't had a problem yet with a Marvel.

BTW, the 600 cpu speed will get you half res capture. For full res capture, it's still undetermined but so far, it will be at least an 800 cpu that will be needed.

I am running a PIII 700 and can pull off full rez with my wimpy little, used to be the coolest toy-FasTrak66. I know what you guys are thinking about the Intel...but I haven't had the scratch to buy a new MB. Plus it was the only AT with 5 PCI and 3 ISA I could find on earth. It is completely full. I think part of the secret to my success is 256M of RAM. Here is my rig:

0 System timer
1 Standard 101/102-Key or Microsoft Natural Keyboard
2 Programmable interrupt controller
3 Monster Sound II PCI Audio
3 Monster Sound II Multifunction Parent
3 IRQ Holder for PCI Steering
4 U.S. Robotics 56K Voice INT PnP
5 Intel 82371AB/EB PCI to USB Universal Host Controller
5 IRQ Holder for PCI Steering
6 Standard Floppy Disk Controller
7 EPSON Printer Port (LPT1)
8 System CMOS/real time clock
9 Adaptec AHA-150X/1510/152X/AIC-6X60 SCSI Host Adapter
10 Matrox Marvel G400 AGP - English
10 IRQ Holder for PCI Steering
11 Promise Technology, Inc. Fasttrak66 (tm) IDE Controller
11 IRQ Holder for PCI Steering
12 PS/2 Scrolling 4D+ Wheel Mouse V5.2
13 Numeric data processor
14 Primary IDE controller (dual fifo)

15 Secondary IDE controller (dual fifo)
15 Intel 82371AB/EB PCI Bus Master IDE Controller

Wow, thanks for all the info. Specially nice to see H popping in for the chat (Hi Bud !)

I'll follow up on the links and see what can be done. I speedread some stuff last week while I was waiting for delivery of the new bitz, and it looked like a soldering iron was required on the CPU. Shows what speedreading can achieve. I'm also an expert at speedtyping, which is why any of you that receive email or whatever from me after midnight think they're reading Greek
