Why don't any MJPEG cards have Firewire IN?

I wonder how Firewire and HuffyYUV would work out?

[Dr Mordrid]

Firewire (IEEE-1394) is a data interface standard, not a video signal standard. HuffYUV requires a YUV (for NTSC it's actually YCrCb) or RGB video signal. Since Firewire isn't a video standard it can't provide either.

That doesn't stop you from using a Firewire interface card with an analog card capable of "YUV". To the contrary, they can compliment each other nicely with the analog card providing video with a higher colorspace (4:2:2 vs. DV's 4:1:1), which is better for adding certain special effects. DV can be used for the rest.

Assuming the issue is having enough PCI slots, such a thing would be nice.

If you are using SCSI, Orange Micro makes a wide SCSI controller with firewire on the same card -- sort of an OHCI version of the Pinacle DV300 minus Premiere, ~$200, They also list a 10/100 ethernet with firewire combo card, ~$130, that I've been trying to get -- but so far its vapor :-(

A Fasttrack100 controller with firewre combo card would make a great card for DV users.

None of these make sense if you have an open PCI slot as the price premium of the combo cards is well above the cost of the same functions on two seperate cards.

An alternative sollution may be to use one of the new Gigabyte boards (Seem to remember model GA6vm7-1394 ??????) that has a firewire port included on the motherboard.

Has anybody seen/used one of these animals?

Gigabyte also has a separate FireWire add-on card. It's called GA-FTI1394. Here in Russia it retails for about $40, while ADS Pyro costs something like $180.

Gigabyte's card ships with MGI VideoWaveIII editing software. I wonder whether it will work with MediaStudio Pro 6.0. What does it take for a generic FireWire card to be compatible with MSPro?

one alternative is to get dazzle
latest card DVnow-AV

LvR,

Does that Gigabyte board with firewire have an Intel chipset? If not, its risky. AMD chipset motherboards are said to work with the Pyro, and by extrapolation any OHCI firewire board. Via based boards are a very comon item in DV problem systems independent of CPU. Is the Gigabyte firewire OHCI?

I can verify that a generic D-Link firewire board (~$50) worked fine with MSPro6. Its important to remember MSPro6 needs the DVpatchII from the Ulead website to be useful with OHCI boards.

No, as far as I know it is Via based - that is why I was wondering if somebody has actually seen/used one of these yet. Here in South Africa we only get the actual boards once they have been superseded by something better most of the time.

Thanks for info, wally.

Gigabyte FireWire daughter card is based on Texas Instruments chipset, so I assume it should be OHCI, right?

Man, it's terrible to hear that VIA chipsets create lots of problems in DV systems. I have a Gigabyte 7ZX based on VIA KT133 (I won it at a Gigabyte event ) and I am planning to build a Duron system including DV editing capabilities. What is the problem - VIA drivers or hardware? Is it a 100% probability, or less?

Hopefully, if I use a Gigabyte FireWire card on a Gigabyte board there is a slight chance I will have less problems.

Firewire with the TI chipset should be OHCI unless the vendor did something stupid or malicious.

Check out John Price's ezboard forum:

There you will find a few reports of success with Via chipsets along with many more with unresolved problems.

I'm not saying Intel is better, just the drivers are more mature and Video Editing is pushing the limits which exposes flaws that "normal" testing doesn't see.

Hopefully Via will get the drivers right eventually, also lots of problems seem to trace back to an IDE controller chip which is not from Intel or Via (Hi Point??)
