Well, we moved from Lexington, Mass to London, England in 1972 and I've not seen a proper snow storm since. Can't remember which winter it was - '69-70, or maybe 70-71 - it snowed so hard for so long that we were off school from Xmas until late February. Lexington had a complex code of municipal sirens which went off early every morning to broadcast information as to which schools were open and which were not. Day after day the relief of hearing that my school was closed, so another day playing in the snow, or knocking icicles off the guttering. You can imagine our dismay when the school board decided to curtail our summer holidays by the six weeks we'd lost to snow...

Enjoy your snow! Am almost jealous...

I have a Kinect v2 + Power supply (Official) that is collecting dust. You can either lend it or buy it off me if you wish to have it permanently.

Get in touch and let's talk about the details 🙂

Hi, this might not be legit for this forum, but a few days ago I received a high end 3080ti (GIGABYTE GeForce RTX 3080 Ti GAMING 12G OC GPU (GV-N308TGAMING OC-12GD)).

This was hard to find and I managed to get it much cheaper than the €1900 going rate at the moment. Long story short, the project that this was part of the build for is no longer going ahead, and I have a card I cannot justify investing in right now.

If anyone is after this level of card let me know as I am looking to sell it. I thought I would offer here as the cards are hard to come by and an excellent choice for Isadora. The card is unused and has a 4 year warranty and us in Amsterdam.

If anyone is interested DM me, I'll keep it off the local sales site for a few days.

First, in general you should go with the framerate of your source material. If your hardware does not support the same low fps (eg. 25fps), then you should go with a multiple of it. This is to prevent recalculation of timing and therefor frames, wich is performance consuming and can cause stuttering. Eg. if your content is created with 25/50fps, you should go with 50hz in all of the systems chain parts (PC -> projector and everything in between). If it was 30/60, go with 60. If your system supports the original fps like 25hz, through all the chain. You can go with this.

If you do live generated content, like animations out of isadora (eg. 3D particles, etc.) it could make sense to have higher frame rates, in certain circumstances. Eg. if the animations include very fast movements. Beside that, it most likely doesn't help to set higher framerates then the content has. It would only take more performance and in the case of recording, would result in bigger filesizes.

I you always work with similar hardware, look for their native refresh rates (projector -> 60Hz) and produce your content fitting to it (30 or 60 fps) keep in mind, higher fps leads to the need of higher hardware performance.

Dear Community,

I thought some here would be interested in a long and fairly technical blog post about the GPU performance of the new Apple Silicon M1Pro and M1Max.

One thing that I found particularly interesting was this line:

In Photo, an ideal GPU would do three different things well: 1.) High compute performance 2.) Fast on-chip bandwidth 3.) Fast transfer on and off the GPU.

For the machines used by most Isadora users, we've had #1 and #2, but #3 has always been an issue. This third item is crucial when doing things like getting a rendered image from the Stage (i.e., an OpenGL texture that lives on the GPU) back to the the RAM on the CPU. Neither NDI, Blackmagic, nor the system that records the stage can accept an OpenGL texture directly; this means Isadora must pull the texture back to the CPU. (This bottleneck is something I've publicly warned users about repeatedly, and cursed privately because it would be so great to make these this process more efficient.)

The line in the blog post that got me most excited was this, especially the part I've put in bold:

The #M1Max is the fastest GPU we have ever measured in the @affinitybyserif Photo benchmark. It outperforms the W6900X - a $6000, 300W desktop part - because it has immense compute performance, immense on-chip bandwidth and immediate transfer of data on and off the GPU (UMA).

I think the real shift here is that Apple is not looking at a GPU graphics card as a gaming device where data transfer back to the GPU does not need to be fast. Instead, they're looking at the GPU as a video processing device, where transfer to between the GPU and CPU should be as fast as possible in both directions. That shift in perspective could be a game changer.

The "proof is in the pudding" as we say in English, but it's going to be pretty exciting to see how the Apple silicon Native Isadora 3.1.1 performs on these machines.

Best Wishes,
Mark

@bonemap, @mark_m

Thanks for pointing out the text in the dialog that appears when you attempt to add a video.

Unfortunately, we can't change that text ourselves.

Do you have suggestions on how we can make others aware of this?

I've asked a question about this on the NodeBB Community forum to see if I can get an answer.

Best Wishes,
Mark

thanks @juriaan - i definitely understand this is not top priority. Izzy users are generally interested in live realtime connectivity and spatial, physical interaction, rather than directly outputting recorded media content. 

It took a while for me to understand the difference, because when I first started using it, I couldn't believe there wasn't a 'Record Out' function. Now I get it. And it's no surprise. There's a reason, as Mark reminds us, for the name of the software itself. It comes from dance performance culture. And it's fab.

But for me, the 'liveness' of Izzy also makes it a powerful media production tool where you can 'perform' editing actions live and use media to trigger events within the edit, as it is 'recorded'. It behaves differently from Max/Jitter, Touchdesigner, VDMX or AfterEffects, etc and it gives a different aesthetic. So recording out is more important for me than others. No problem. 

The good news (update) is that i finally got midiStroke to work after @jandraka (many thanks!) suggested it months ago. Thanks also to you @juriaan for what i guess is the Windows equivalent in this thread..? 

For some reason midiStroke wouldn't recognise Isadora Virtual Out, but suddenly it does. Maybe a Catalina update..? Probably my error. I don't have much Midi experience.

But now I can send keystroke combinations out from Izzy and start and stop Syphon Recorder automatically from within a scene. This is like a powerful upgrade for me. A happy ending. I hope it will continue to work. Thanks to those who have contributed to this enquiry. Hope this is useful @yellow ...

I do... Even using Sierra on an old one... Shouldn't I?

@xgunnar

If the Windows Version you get, is a windows 10 Pro, than it is what is says. The price doesn't mean any functional differences. The prices are a kind of discounts. What you buy is a licence, which should work with any official Windows 10 Pro copy.

But there are some risks with the cheap offers. Here is a detailed Article about this question:

experience moving their Izzy patches from Mac to PC

 Generally moving between Mac and PC is very easy, however, there are a few things you must be aware of.

Mac has CI actors, AU actors, and Quartz actors. These do not exist on PC
In your case I wonder if you are using audio routing via AU actors inside Isadora?Syphon becomes Spout (some re-patching required to change these actors)3rd party plugins you have used may not be available

I work with Ableton, Isadora, and even some 360 video at times.. I have no issues on PC

Generally any Gaming laptop will serve you well. There are many conversations in the forum about PC laptops.
I suggest being sure the laptop has at least a mini-display port built in. These ports are always built into the dedicated graphics card (not the intel gpu) and offer a lot of extensibility.

This forum post is worth reading: https://community.troikatronix...

Hey everyone! The sun is at last shining in the UK! @mark just wanted to let you know that I've just got my hands on the book Digital Scenography by Neill O'Dwyer that you mentioned a while back - it's finally been published. I'm reading through the fascinating 1st chapter all about Troika Ranch and Electronic Cafe International as I return to your inspiring Isadora Guru session #20 with Dawn Stoppiello! Okay better get back to my research project on remote performance! Takes care all 😊

@bonemap I'd agree with all Russell says here. The other thing to watch out for with the ultra-short-throws is that they often have quite a large 'pitch', so if you place the projector on the floor it will project an image 'up' on to the wall; it's hard (or impossible) to get an image to reach the bottom of the wall because the angle of the mirrored lens has to shoot back past the body of the projector itself. Obviously if you are rigging/mounting it over head this is reversed and the image shoots 'down' leaving a gap at the top. This is a pain if, for example, you want to fill a wall with an image from floor to ceiling. Because of the extreme optics, as soon as you angle the projector off the horizontal things get messy quickly with the huge amount of keystone needed. Just something to watch out for and it obviously varies massively between makes/models especially at the budget/mid range prices.

Even with the top end kit it's an issue: the massively popular Panasonic DLE030/DLE035 lenses for the single-chip projectors have a huge pitch, dims A1/A2 in this diagram. The top-of-the-range D75LE95s for the three-chip monsters are slightly better, but it's still an issue. This can sometimes be even more a problem with flying cradles etc that make the body of the projector bigger and get in the way of the beam. 

The Epsons mentioned above have a really clever lens, the EP-LX02 that looks like a periscope and bends back round under/over the body of the projector so you get a more traditional 'flat' projection without the pitch. It's probably the one department where the Epsons outperform the Panasonics in my opinion. They're very expensive though; looking forward to when that style of lens trickles down to the cheaper models, as it no doubt will at some point. There may well be some cheaper classroom 'whiteboard' style projectors that already do this.

On the wide but not crazy-wide side you can get projectors with a fitted lens that has a bit of a zoom for some flexibility. I just did a gallery install with a pair of BenQ W1210STs, they had a 0.69-0.83:1 zoom and did a lovely job, they're only 2k lumen but it was a very dark room.

I cannot see my ticket status any more. The link is gone and instead there is a link to a login page but my login data are refused.
