HD-SDI to computer encode (HDV, small PCI)?

[Tom Fazzio]

Not for now, hence the conversion down. The HD-SDI is the only available output from the switcher.

1. Switch over to SDI for the switcher output, if you can, then capture.
2. Try running through a VTR for down-conversion, then capture.
3. Don’t use a laptop. You’ll spend $2500 to get HD-SDI into it. You can do it for $395 with the new Blackmagic Design DeckLink SDI card if you have a PC or Intel-Mac with PCIe slots.

If the damn Blackmagic Video Recorder would be available, you would have a $199 solution. They showed this at NAB 2008. I don’t know what the issue is, but it’s SDI to USB and does real time h.264 encoding.

What about the AJA IOHD or MOTU V4HD FireWire Video Interface. They can be had for 2600.

I wish I was good at one thing rather than average at many, but oh well.

[Bob Zelin]

Nick –
these are not h.264 encoders for the web. They are video capture products.

He just mentioned ways to ingest HDSDI into a laptop. Both these products do that. Apparently I missed the whole H264 web casting part of this conversation.

I wish I was good at one thing rather than average at many, but oh well.

Oops,

I may have responded to your post which does mention H264 encoding. I meant to respond to the original poster.

Bobby, Bobby, Bobby,

The IOHD + Wirecast is a perfect solution albeit more than a $1000 and less than $5000. What I am confused with though is why HD SDI to HDV? Is the source greater than HDV Tom? If it is HDV and you can go firewire to Wirecast, you are about $550.

Thanks for all the feedback. I will try to explain a little more detail.

The point of the project is two-fold: 1. use HD-SDI equipment as a pilot for a much larger project, and 2. provide live webcast (at a decent quality but not full HD) of multicamera events.

Right now, I use Windows Media to stream NTSC signal. I thought I would be able to convert HD-SDI to HDV and stream with Flash Encoder. Turns out HDV is not something that either WME or FME want to handle (will Wirecast injest HDV for a stream?)

So, is there a small-PCI card for HD-SDI and some software that will encode live to a viewable speed/size? Or is there software that will live encode i.Link from a Sony PMW-EX30 for the stream?

[Jeff Mack]

Wirecast on a mac will work. If you bring in HDV, you will need the HDV plugin. If you’re on a mac, Matrox MXO2 will take your HDSDI signal into wirecast and so wil the AJA IOHD but if you are live switching your switcher can send the HD SDI stream to either or you can downconvert from your switcher. Tri Caster does it all but not $1000.
