Live HD Inputs & Configuration for HD
-
@mc_monte -- dude been wondering about going from a D-SLR --> Intensity --> Izzy. Glad to hear it works. Wondering about getting rid of those boxes... you can't remove them with the display button on the T3i? Did you need to run EOS Utility to grab the video? Alternatively, you may be able to remove them with Magic Lantern -- an add-on to the Canon firmware. It isn't officially supported, so be warned, BUT it's supposed to be great. Removes the time limit per recording, for example. Triplehead --- you want to input through the HDMI from a camera and output through the 3H2G?1080p footage -- if you're just running that it should be fine (esp. w/ no fx). Make sure you're using photo-jpeg! See what the frame rate is when you run it in quicktime (using an FPS monitor like atMonitor) whatever it tells you there, sans effects and with photo-jpeg, should run the same FPS in Izzy. If it doesn't -- you've probably got a messed up pref (or a bad GPU / low RAM)! Good luck.

You can remove the information, but the white, rectangular focus box stays no matter what. However, the T3i's controls let you move the position of the focus box, so you can stuff it into the corner of the frame (as opposed to having it sitting in the middle of the shot). This way you can easily use the Crop actor to clip it out in Isadora (obviously, you lose part of the image though -- you're basically reduced to 720p if you do this). I did not need to use EOS utility -- the Intensity just sees the video input from the HDMI output on the T3i. I'm aware of Magic Lantern, but hesitant -- from what I understand it will cause a crop of the footage anyways, so my workaround seems to fit the bill fine for now. Beyond that, it was pretty much plug & play after I installed the Blackmagic drivers.
Regarding the Triplehead, I'm wondering if you can do this:Retine MacBook Pro (ultimate configuration): HDMI port => Triplehead => Beamer #1, Beamer #2, Beamer #3Doing so would leave both the Thunderbolt ports open for additional displays or capture devices.As for my footage, I'll fiddle with it in the morning. I will try running the footage into photoJPEG and see what happens. My mini isn't particularly powerful, but it's a temporary machine. -
I see no reason why a 3H2G wouldn't work! I'm assuming that a standard edition 3H2G can go HDMI port out --> HDMI --> VGA adapter --> Triplehead --> Beamer x 3. I just got the MBPr today and am planning to test it out within the next day or so. I'll let you know how it goes here!
Good luck getting Izzy to up the FPS! Should work once you encode -- otherwise something else is probably going on. -
HDMI has no analogue information, the HDMI to VGA adaptor will not work, you will have to use a thunderbolt port. Also HDMI is a video standard, I would be very surprised if it lets you get anything above 1920x1080, but let us know how you go. Magic lantern is a great upgrade and works a treat, well worth it, if you dont like it just boot without the magic lantern card in. Generally the live output of the cheaper DSLRs is pretty low resolution, it is always cut down and scaled.
I have been using the canon HV series of cameras, they are pretty ood quality and very cheap and reliable. You get reasonable control and manual settings and a live low latency full frame HDMI out.Fred -
Don't be afraid of the Magic Lantern! It works really well, and allows very detailed control over all settings, and is super easy to bypass, and despite the official warnings, there aren't any reports of it damaging anybody's camera who weren't damaging it in some other way (leaving it on for hours and hours... with the auto-off disabled)
But is summarily gets rid of that foolish white square. -
@Ipearse my only colleague who tried it ended up with a fried SDHC card. I want to try it, as well, but am worried about just that! Anyone else have that experience?
-
Also curious about Latency w/ live HD 1x1 in Izzy. What have people experienced?
-
Hi,
I think latency would change quite a lot depending on the hardware used for capture.It's how it goes for SD so...Mehdi -
Fried SDHC card? Wow. We use it in the film department of the university I work at on 10+ cameras, and nobody has ever had that problem. No problems at all, in fact, and these are students using them...
-
Live 720 P is hovering at about 1/8 second latency with 0-6 FX -- setup is real nice. Next up is to try w/ Blackmagic and SDI.
@lpearse -- good to hear you've had such success with it! I'll let my buddy know that he may be making some rookie mistakes... definitely makes me want to try it myself! -
Hello allI don't know if this is the right thread. But is it possiple to capture live from a go pro and at what frame speed? Anyone tried that?
Thanks -
Look at this
http://goprouser.freeforums.org/howto-livestream-to-pc-and-view-files-on-pc-smartphone-t9393.htmlI think it would be more for HD3.You can do capture with HD2 over HDMI but you get data overlay and about 28-29fps and decent few frame delay. I use MXO2 Mini set 1080p **8bit** YUV -
Thanks Vanakaru. Always precious.... I'm sorry I see this so late.

Hello, we can only have 2 thunderbolt intensity OR 2 thunderbolt mini recorder at the same time capturing HD. But also 1 thunderbolt minirecorder and 1 thunderbolt intensity. With the intensity usb it is the same: we can have in isadora double HD capture at the same time. Basically Blackmagic drivers are for thunderbolt OR USB devices and one cannot mix usb AND thunderbolt but we can have 2 at the same time (maybe 3... Isadora (non qtkit) works fine with them using the usb beta 9.7.9.You cans see detailed text here with cpu speed. All running at 30 fps rock solid.See my computer specs in the signature.Ciao
