      Thanks Vanakaru,

      That's exactly what I meant by talking about "latency" : I'd like a good "lip-sync" when live filming my actors on stage.
      I'm about to test the blackmagic Intensity Usb3.0 (someone is going to lend me one).

        Hi Fifou,

        I think the usb3 shuttle from blackmagic is not compatible with mac osX. It's a windows only device.

          You're right Mehdi, but drivers for Intensity Shuttle USB3.0 on mac just arrived !

          But if I buy one, I'll buy the thunderbolt one.
          Do you think an Intensity shuttle thunderbolt and a Matrox Tripplehead thunderbolt can work together on the same port ? (With a thunderbolt hub of course) ?

            I don't think there is such a thing as a thunderbolt hub - you need a device with two connections (a through connection) to be able to have more than one device connected to a computer with a single thunderbolt port

              There is the Thunderbolt dock but don't know too much about it if i'm honest.

              I would love theĀ Intensity Shuttle USB3.0 to work on Mac; would save a few quid! Not just for the device but also the expense of the thunderbolt cable!

                From BM forum:

                "I can confirm that the USB 3.0 Intensity Shuttle works with the Macbook Pro in Mac OS X 10.8.4\. Use driver 9.7.9."

                  I have a Belkin Thunderbolt Dock and can answer any questions about it. That being said, it doesn't give you any more thunderbolt ports than your computer already has so I don't know what good it would do in this instance.

                    I just tried, It works !
                    Blackmagic Intensity Shuttle USB3.0 works on mac OSX 10.8.4. Install osx drivers, plug the card, driver asks for online update, update, it works !
                    Latency in composite capture is much more acceptable. Is still have some issues with deinterlacing. This card is supposed to deinterlace but it seems it doesnt work... For the moment Isadora does it.
                    I'll choose this USB3.0 card and save my only thunderbolt port for my forthcoming Matrox Tripplehead..

                    Thanks all for your comments.

                        Just sharing my own experience :

                        I've just bought an Intensity Shuttle USB3 and it works on my mid 2012 (non retina) MBP on OSX 10.8.5.
                        But I had to test every single input settings before to find which one was the good for my GH3 and my Gopro (so if you have a black screen while trying to input video from this card, just test other input settings).
                        I was thinking it would discover itself what are the right ones... (like my TV do...)
                        And I can't input signal at 1080/25p (I had to change my GoPro record settings to 24p...).
                        I hope that BlackMagic will fix that in their next driver release...

                        MBP mid 2012 - quad-core i7 2.3GHz - 16GB RAM - 512GB SSD - OS 10.9.5

                          I had to search right settings too.
                          And it seems deinterlacing doesnt work.. for the moment I hope.

                            I wonder how you Gopro works. I have stayed away from using it for live and not testing actually. Do you go HDMI out and do you get clean frame without any icons? I have HD2 sitting araound that I do not use much, but for live there would be a life for it.

                              I did a quick test with my Gopro HD Hero 3 black HDMI out yesterday and it seems to work !
                              To remove icons, I had just to set OSD option to Off. And for the settings, I selected 1080/24p on GoPro and Intensity shuttle.
                              If you can't make it work clean, just tell me and I'll give another try.

                                OK! I got the mini(micro) HDMI adapter and was able to hook my idle GoProHD2 to Matrox MXO2. Great quality 1080p PAL 25fps. I have a project requiring closeup lens camera and this is absolutely perfect. Now when new HD3 is about to come out I see HD2s selling for 100EUR. It would be great camera for live capture - latency with MXO2 is about 1/3 of a sec, picture is very good on daylight and not too bad with poor lighting(gets grainy) and as a great bonus you can record what the camera sees while broadcasting live. Powering via USB mini connection works fine. And it is a small camera.

                                  The Hero3 black edition is far more expensive, but really better in low light conditions if you need to use it on stage.

                                    I have a LFG4 installed in my MacPro with 2.8Ghz quadCore Xeon, 20GB Ram and dual ATI Radeon HD5770

                                    I am capturing two NTSC streams at half res from the live IMAG cameras, and compositing them with my video content picture in picture style. I am running at full 30fps but there is still a substantial amount of latency and "lip sync" issues with the audio which runs straight through FOH console. Are there any ways I could optimize my system or Isadora to reduce latency?

                                      You'll always have more or less latency.
                                      Maybe you could add a delay to your audio to resync audio and video.. !

                                        Adding a delay to the audio isn't an option for us. I can accept some latency, but I do need to improve it. What are some parameters that affect latency that I can check out?

                                            Sorry, I don't have clear answer about that.
                                            Try to tweak a right balance between resolution-codec-quality in the live capture settings box...
