To do some live streaming I’ve looked at many solutions and this one seems (at this point) the most ideal for my multi camera setup : hook up 3 gh3’s to 3 Ultrastudio mini recorders with thunderbolt and use wirecast to do the streaming and encoding on the mac pro/hackintosh.

I’ve seen however some conflicting messages on forums where it seems that the GH3 signal will not pass through the mini recorder, so does any one have experience with this? Can anyone confirm the mini recorder works with the GH3 and wirecast?

I believe the GH3 has 4:2:0 out and the codecs supported by the mini recorder are:   AVC-Intra, AVCHD, Canon XF MPEG2, Digital SLR, DV-NTSC, DV-PAL, DVCPRO50, DVCPROHD, DPX, HDV, XDCAM EX, XDCAM HD, XDCAM HD422, Apple ProRes 4444, Apple ProRes 422 (HQ), Apple ProRes 422, Apple ProRes (LT), Apple ProRes 422 (Proxy), Uncompressed 8-bit 4:2:2, Uncompressed 10-bit 4:2:2.

So perhaps the GH3 might not work due to different colorspace?

 Here a post where you see a setup using to minirecorders thunderbolt + usb camera to stream live with wirecast: htttp://forum.telestream.net/forum/messageview.aspx?catid=45&threadid=13444 The guy doesn't use a dslr but dedicated camera but you can use the mini recorders with wirecast, only question is, will it work with the GH3?!

Hope one of you can shed some light on this matter

I've been looking around for info on how to use my new 2013 macbook pro to show live video primarily, and images if possible, that are being recorded/photographed live from my GH2... essentially using my Macbook as a monitor.

There is a thread on PV that is a couple of years old which I have posted to, but through I'd open this up as a new topic as well, as I'm sure there are people out there in GH2 land who could do with this info as well. Here's a link to the original topic: http://www.personal-view.com/talks/discussion/1207/gh2-live-streaming-solutions/p1

I'm hoping that in the 2 years since the original thread, the tech options have moved on. My macbook has thunderbolt, which, from experience connecting macbook to tv, works well with hdmi, and as thunderbolt connectivity can be used to transfer data from a hard drive back and forth, it must be a 2 way connection, so theoretically should allow for possible hdmi data being inputed to my mac.

I am relatively new to this and am trying to gather information, as this forum has been so informative in the past, I wanted to ask you guys what you would do in my situation? I would appreciate cheaper options if possible, primarily wired options as from scouring the web, there are issues with data signal interruptions and signal distance on wireless options.... plus wired is, I expect, considerably cheaper!

Can you help?

Thanks, Rob

At the Computex trade show in Taipei, Intel showed a key-shaped prototype 128GB thumb drive that plugged directly into a computer’s Thunderbolt port. The drive required no cable and resembled flash drives in size.

This is one of the first thumb drives demonstrated using Thunderbolt connectivity, which is the fastest technology available to transfer data between computers and peripherals, said Oren Huber, a Thunderbolt engineer at Intel Israel.

Everybody seems to be sharing video these days - at higher resolutions than ever. This always-increasing demand has helped expand growth and adoption of Intel's Thunderbolt™ technology in 2013, especially for the video editors creating the best and richest content. Originally brought to market in conjunction with Apple*, Thunderbolt is now a standard feature of Mac* computers sold in the market today. The last year has also seen the PC industry get on board in earnest, as Thunderbolt is currently included on over 30 PCs and motherboards worldwide, including on more than a dozen new 4th generation Intel® Core™ processor-based products. In addition, there are more than 80 Thunderbolt-enabled peripheral devices, covering everything from storage drives, expansion docks, displays, and a myriad of media capture and creation hardware. More than 220 companies worldwide are developing Thunderbolt-enabled products, and that's only going to increase.

At the video geekfest National Association of Broadcasters (NAB) show in April, Intel announced plans for an important advancement in Thunderbolt technology – the upcoming controller codenamed "Falcon Ridge" running at 20Gbs, a doubling of the bandwidth over the original Thunderbolt. Named "Thunderbolt™ 2", this next generation of the technology enables 4K video file transfer and display simultaneously – that's a lot of eye-popping video and data capability. It is achieved by combining the two previously independent 10Gbs channels into one 20Gbs bi-directional channel that supports data and/or display. Current versions of Thunderbolt, although faster than other PC I/O technologies on the market today, are limited to an individual 10Gbs channel each for both data and display, less than the required bandwidth for 4K video transfer. Also, the addition of DisplayPort 1.2 support in Thunderbolt 2 enables video streaming to a single 4K video monitor or dual QHD monitors. All of this is made possible with full backward compatibility to the same cables and connectors used with today's Thunderbolt. The result is great news for an industry on the cusp of widespread adoption of 4K video technologies.

"By combining 20Gbs bandwidth with DisplayPort 1.2 support, Thunderbolt 2 creates an entirely new way of thinking about 4K workflows, specifically the ability to support raw 4K video transfer and data delivery concurrently," says Jason Ziller, Marketing Director for Thunderbolt at Intel. "And our labs aren't stopping there, as demand for video and rich data transfer just continues to rise exponentially."

Professionals and enthusiasts alike will be able to create, edit, and view live 4K video streams delivered from a computer to a monitor over a single cable, while backing up the same file on an external drive, or series of drives, simultaneously along the same device daisy-chain. Backing up terabytes of data will be a question of minutes, not hours. And finally, since Thunderbolt 2 is backwards compatible, original investments in cables and connectors continue to pay off while supporting dramatically improved performance. Thunderbolt 2 is currently slated to begin production before the end of this year, and ramp into 2014.

If this camera delivers, this is going to be my next camera. BlackMagic Design is gong to deliver what RED promised with the original Scarlet announcement. Thunderbolt connector, free Resolve, Touchscreen for metadata entry!

This happens when honest companies like BlackMagic Design, which don't have to artificially protect their high-end gear (I am talking about you Sony, Panasonic, Canon) start entering the camera business. If the image quality lives up to the specifications, this is going to be THE camera to get. Sony, Canon, Panasonic won't be happy in that case. The 5D Mark III could do the same but Canon doesn't allow it because of C500/C300. Same for Sony, Panasonic. If BlackMagic delivers, I will respect them so much!

I won't be surprised if BlackMagic Design will launch their own NLE down the road as well.
