Do you think that this product:

could be used to capture
an external incoming HDMI signal using Vegas Pro 13 ?
It seems that the IEEE 1394 firewire signal should tell
Vegas to capture from its HDV capture selection right ?

Whether it could be used as you suggest, I have no idea. However, I would think you should look for another solution for capturing HDMI for a couple of reasons. First, if you look at B&H Photo, you'll see it's no longer available. Second, and more importantly, you'd most likely be converting progressive 1920 x 1080 HDMI footage to HDV which is interlaced (1440 x 1080). You would be losing horizontal resolution as well as having to de-interlace for renders for any web distribution. Plus, at 433 quid, it seems a bit pricey. E.g. a Blackmagic Design Intensity Pro 4K card is less than $200. Whether it plays with Vegas, I have no idea. Regardless, I'd search elsewhere. Perhaps someone else could make some recommendations.

Right now I have an offer at $250.00
for a used but working HD50 ..
By the way, after a lot of intenet search
I could not find any device that would receive
an HDMI source and convert it to HDV
through a firewire cable that Vegas would accept
as a capture source to record..
Vegas has been designed to capture external camcorder (DV or HDV)
sources through a firewire cable so no devices seam to fit
whenever an HDMI feed comes to be recorded (captured).

So any suggestion for a device whose workflow would be
-- HDMI source to HDMI video capture device input then
-- firewire device output to PC (captured by Vegas Pro) ???

Could you not use the BlackMagicIntensity Pro 4K card. It has HDMI input and can be used as a capture device. Have used it to capture within Edius but not used it as an input device with Vegas. It works as a preview output device with Vegas so may well work as an input device.

B&H may be able to advise

Thank you Geoff,
Again I do not want to buy a PCIe slot
mother board type dependant card..
I look for an external HDMI video capture device that would be
firewire/Vegas compatible.
I'm so disapointed the technology is that
limited with such devices for specific task..
They go on the moon but there are no HDMI to HDV firewire
devices available to buy anywhere..
I must be a martian with too dificult needs..
Maybe a should have choose another type of editor than Vegas..
Maybe another video editor soft would accept many more
types of HD capture devices..
I will continue my look around again.
Thanks anyway.

[Jean-Pierre Desrochers] "I look for an external HDMI video capture device that would be firewire/Vegas compatible."
It looks like the device that you found should do what you want. Vegas Pro should see it as an HDV camera can capture it's output.
[Jean-Pierre Desrochers] "I'm so disapointed the technology is that limited with such devices for specific task.. They go on the moon but there are no HDMI to HDV firewire devices available to buy anywhere."
That's because no one is using the HDV format anymore. Most people abandoned tape-based formats several years ago and so you won't see any new HDV devices.
[Jean-Pierre Desrochers] "I must be a martian with too dificult needs.."
No, you are just looking for something that no one else needs or wants anymore. There are better ways of acquiring from HDMI.
[Jean-Pierre Desrochers] "Maybe a should have choose another type of editor than Vegas.. Maybe another video editor soft would accept many more types of HD capture devices.."
Vegas Pro supports AJA Io Express, KONA 3x, LH, LHe, LHi, LS, or LSe SDI cards or the Blackmagic Design HD Extreme, Intensity Pro, or HD Extreme 3D SDI cards. That's a fairly long list of devices. Most people who have access to 1920x080 HDMI don't want to capture it as 1440x1080 HDV because you loose horizontal resolution in the process.

If you don't want an internal card the Blackmagic Intensity is a USB device but it has very specific motherboard requirements and doesn't work with any Dell computers. You would also have to capture with their software and then just edit with Vegas Pro.

Thank you John for your explainations..
As you saw I'm a newbie that had no problem capturing
DV video with my old Canopus ADVC-100 inside Vegas 8 in the past.
So I moved to Vegas Pro 13, and now I want to capture
HDMI external signal to Vegas 13 with lots of struggle..
I changed my PC for a powerful Intel i7 with 32gb of RAM
and 3 separate HDD's to do the job easily.
I don't own any HD camcorder
(which is best suited for Vegas 13 HD capturing)
so I'm focusing on ANY type of device that would
receive an HDMI stream and 'send it' to Vegas as a capture process.
That's why, so far, I only found the Magewell XI100DUSB-HDMI HDMI to USB 3.0 Video Capture Dongle to do the job.. Well I was wrong.
Vegas is 'picky' in accepting capture device in HD format.
And since I'm a newbie I do not know all the 'video technical terms'
of videophiles guys like you. So I get easily lost in the ocean
of technicalities specialy in the HD world.
A goog thing for me would be to go through some kind
of HD capture technical seminar for Vegas Pro 13 including all
aspects of what I'll step on in the process to do the best
decisions in buying equipment.
And about the Intensity Pro USB3 capture device for example
I know there are issues about PC motherboard USB3 chipset..
I own an ASUS X99 motherboard so I'll have to check if the Intensity Pro
would be accepted and by the motherboard AND by Vegas itself.
Sorry for the long post but that's my (frustrating) story so far.
Thanks john.

[Jean-Pierre Desrochers] "I know there are issues about PC motherboard USB3 chipset.. I own an ASUS X99 motherboard so I'll have to check if the Intensity Pro would be accepted and by the motherboard AND by Vegas itself."
No, it's not compatible. The BM web site states:

USB 3.0. Requires an x58 based motherboard with onboard USB 3.0, or a USB 3.0 PCI Express card and a x58 or P55 series motherboard.

I wouldn't chance it. You might even want to look into a HDMI recorder like the Atoms Ninja. These files can be dropped right into Vegas Pro. As long as you don't use too many files you should be OK but be warned that Vegas Pro has memory limitations when working with QuickTime files like these.

Like I said the Grass Valley ADVC-HD50 HDMI to HDV converter should work fine as long as your motherboard has a Firewire port or you add a Firewire PCIe card. Of course, Windows 7 has issue with some Firewire chipsets too.

You can also get standalone boxes. E.g. https://www.blackmagicdesign.com/products/intensity/techspecs/W-INT-03

Hi,
I finaly bought the Grass Valley ADVC-HD50 capture device
and just received it. What a nice device !
I tried it in Sony Vegas Pro 13 and now I can capture external HDMI
to Sony Vegas Pro 13 directly using Capture HDV.
I found Vegas captures in MPEG .M2T format.
All I have to do is click the PLAY button inside the HDV capture window
to see the incoming image then click the record button to start capturing. EASY !
I captured a 60 seconds clip and that gives a 190Mbytes file size.
It seems that this MPEG compression is a bit too compressed from Vegas
at capture time.. What do you think ?
Is'n it not too compressed anyway to use it for editing afterward ?

Here is a snapshot of the clip's info from MediaInfo:

Vegas Pro isn't compressing anything. This is what the device produces. You have no control over this. HDV is a fixed compression and the same bit rate as DV and you can't change it. That's what makes it HDV.

This is fine for editing. I edit HDV all the time from my Sony Z1U and it looks great.
