Has anyone tried these out or heard of them? I found them in B&H a couple years ago but didn't pick one up at the time. They seem rather neat, and also only cost around $25.

iRing MIDI Controller

Also has an SDK apparently.

@woland brescia is a small city, 200k citizen, I think to be the only Isadora user here...but maybe if some one near me (Milan Venice and so on..) is reading this message please contact me...we can try to create a meeting iand invite woland!

Hi,

In case you need to replace the filters in your projectors.

Recently I had a number of 'filterless' InFocus projectors become dysfunctional all at a similar time (what is that all about - an internal obsolescence clock that tells the projector to stop working?) 3 out of 4 projectors malfunctioning at a similar time with only a fraction of bulb hours used. My alternative was a turn to some older NEC projectors as a back up. When testing these, one would turn on and then off after a couple of minutes and another displayed the "Please clean the filter" message. It appeared to be time to check the filters. When I removed the filter cartridge on one there was no filter material and on the other the filter material disintegrated (this is not unusual for filter foam). However, I needed these machines to be up and running in the next day and there was no supplier for replacement projector filter foam locally. The only supplier of NEC filters was through Amazon, and that would take over a week to ship from somewhere overseas. The cost for 'branded' NEC filter foam at the lowest price was US$13 plus postage. I needed an alternative urgently. What I found was a local electronics supplier of a 'plastic fan guard kit' for less than half the price, that had a larger sheet of exactly the same filter foam loosely enclosed between two halves of the plastic guard.

Now the old NEC projectors are running smoothly again, and I have excess filter foam for a couple of other projectors.

@mark_m

thanks for your advice. there is certainly a drift towards Windows based operation of Isadora in this forum! I love the sound of the Blade laptops that @Fred uses!

@mc_monte knows that probably

Hi,

It is interesting that Microsoft have re-evaluated and discontinued the Kinect for Xbox at a similar time that Apple have announced a depth camera in a forthcoming iOS device (iPhone 10) - although Apple's face tracking IR camera may not provide the range that is useful for stage and installation projects. I would have thought that there might be a whole range of general purpose depth cameras that become available for 3D scanning of large objects etc. - but perhaps not? It appeared to take a long time for Apple to come up with a device after buying out and taking over the PrimeSense depth camera back in 2013.

After a discussion with @keftaparty about latency differences between thunderbolt and pcie blackmagic capture. I compared a deckilink duo 2 and a mini recorder. The setup was a timecode movie playing from my laptop while mirroring to a HDMI to SDI convertor, one SDI output connected to the mini recorder and one to the duo. The mini recorder shows 3 frames latency and the pcie card 2.5 (all this is at 25fps, so 120ms or 100ms latency.

The mini recorder does not capture 50fps so I could not do further tests but the duo does and maintained 100ms latency. There may be latency added by the HDMI to SDI convertor and of course by the screen, but the test seems consistent with my previous results and other peoples experience.

Here is a video of the output, more detailed data could be collected with an SDI signal analyser.

Hi Ismael,

I've used in the past one BlackMagic Intensity Shuttle USB3.0 (analogue capture) and a Matrox Tripplehead DP Edition (2*1920x1080 output) together for a show.

It worked great on my MacBookPro 15' - QuadCore i7 @ 2,66GHz 2012.

Best

@FabioQE data path is a great one, expensive but I like the driver/settings setup way more than matrox. And yes MST hubs are an amazing addition to windows machines.

Another cheat if your machine supports 4k hdmi is this https://www.aja.com/products/m...

In quadrant mode it will give you 4 HDsdi outputs from a single hdmi 2.0 output.

Couple of things... I got one and it worked well, but the bluetooth failed after a week or so. My dealer (Sweetwater) replaced it quickly and the new one seems to work fine. The irritating-to-me sleep mode can be remedied by using the computer-based editor to turn off LEDs in the global tab. Other than winky feeling keys, it works fine. Small, light with some unexplored features.  - John

Hello all,

Ran into this online and thought it might interest some of you, especially if it can be interfaced with the Live Drawing actor.

For the handful of you into NDI (and the rest of you all who should be), NewTek just released it's Spark HDMI/SDI to NDI boxes and PTZ Camera.

The spark comes in HDMI and SDI flavors, and will connect that source as an NDI source on either a wired or wireless network. They're rather cheaper than bird-dog's option. Unfortunately no 4K, but I may be the only one that cares about that.

The PTZ is will output directly to a network as an NDI source (or via HDMI or SDI), and is controllable (pan/tilt/zoom) via that network as well. It also uses Power-over-Ethernet, which is surprising and really cool.

for browser the link posted by Dusx is  good, I've used for a show some time ago and it worked fine

And that's why I think you have to go with a tried and tested solution, rather than hoping for the best with the hardware you happen to have

Please submit a bug report.

I have been able to verify some issues with a HID game controller as well on my system.

I recently bought a Datapath VisionLC HD2 HDMI capture card and I wanted to share my success.

Above you can see it capturing an output from isadora running at 1920*1080 and up-scaling it to 3840*2160 (see below). I have since read it can capture a single HDMI at full 4k - which I will try one day.

The hardware cost £435 which is pretty cool as this can capture DUAL HDMI inputs. So its almost £200 a channel input capture.

Frame delay is minimal but the quality is amazing. 

It's also: 

PCI Express Gen 2 x 4 low profile

And it is indeed low profile! I was very tight on space.

I have done now hardcore testing yet but it works and I will keep you posted on my research.

@Fred Hopefully it will be supported in high sierra. I get your point on displayport flexibility. Thanks so much for all the info. Much appreciated.  

Hi 

I am going to build a solid workstation with a MacPro 5.1 for Izzy and the question is...  which GPU to use for 4 outputs in 1080p?

I have a Matrox TH2Go DP ... absolute fail - no Full HD support on my MacBookPro (Thank you Matrox) for 3 outputs 😞

What's stable and powerfull enough to play on 4 FullHD displays (projectors)?

This one's look good, but what about GPU (OpenGL, OpenCL) acceleration for Actors?

NVidia Quadro M2000, 4GB GDDR5, 4x DisplayPortAMD FirePro W7000, 4GB GDDR5, 4x DisplayPort

... or is it better to use a consumer gamingcard with Titan or Pascal GPU?

There is also the Blackmagic Decklink Duo 2... it's complete without acceleration... but with the benefit of inputs...

So whats your opinion... Thank's a lot...

Tom

Thanks for the advice.

We use an ultrastudio express in thunderbolt(1). But you were right, the camera itself has a latency of 122 millisecondes. We pass through an atem to choose which camera we use (+20 milliseconde) and then, the capture itself has a 140 millisecond malus. 

That split one problem in two problems.

 

@CitizenJoe: Thank you!
