Video capture for Linux is fully supported by Blackmagic. Not only is there a driver, they give apps too. So there's a proper video capture app. Compared to my experiences with audio, I'm really impressed by how smoothly it all works.

Having said that, I'm now using their Shuttle to record and then edit on a computer in another room. This is actually much easier, as the Shuttle is small enough to sit under the monitor in my video rig, unlike the computer...

:omg: :omg: You just blew my minddddddd. :deadbanana: :deadbanana: :deadbanana: :deadbanana: :deadbanana:

Great schema too. This is amazing and now I want to see how a microcontroller would be in this situation. I knew BM had an SDK but their information is rather vague. They say you can do cool things with it but after I've seen many companies do the same I don't put much stock in it.

Really encouraging, thanks for the info!! :omg:

I have had the exact opposite experience with Matrox.

First off, I started on Windows. Had issues getting it operational on Win7 with the PCI express card. Called support and they walked me through everything for an hour. Even logged in to my computer remote to fix things. What company supports used gear bought on Ebay? I was really impressed. Second, the mini is very STABLE on mac but I had lots of issues with Windows. Many of the features, like capturing in different codecs directly and the hardware upscaling are not available under windows. They can only be done with a mac.

Now I have a mac, switched to thunderbolt and I had some issues. Called support and the walked me through the set up again, was up and running in 5 minutes. The one issue I have found is that the host cable is EXTREMELY sensitive so not having it plugged in correctly was my most common issue. However, the light on the mini makes it clear when it's not connected properly. All in all very satisfied.

Fascinating. When you contacted them, what was your support process like? For me it didn't help one bit and their forums were repetitive. And plus they aren't supporting current operating systems so it can be challenging I the future. Ive been there with other devices and didn't want to get such in limbo. Or alter my OS just for this. What OS are you running? I tried on 3 different operating systems with no luck. I've met a few people that have experience the same. Probably the gnomes again. No upscaling along for Windows? That sounds odd. And the sensitivity of the host cable? That's even stranger. It's really stable with sensitive cable? That would be a downward spiral for me. I'm not skeptical about your process just the device itself. I'm really excited you shared this because the thunderbolt version seems to be rare around here. Got any videos or pics to share?

blackmagic settings? (using intensity shuttle thunderbolt)

Post by elklotzy » Fri Mar 11, 2016 3:11 pm

question: for those using blackmagic, what settings are you using? i'm having trouble with my new lzx system (out from visual cortex) and blackmagic intensity shuttle (thunderbolt version)...

**EDIT: RESOLVED**

i'm also on the hunt for a decent capture solution.
I don't have a lot of cash right now, so my price maximum is about 70,- euros
I borrowed a black magic intensity shuttle usb3, but it does not work on my system.

do you have any tips what to choose / avoid?
I want to capture video from a TrinsRGB-1c and PAL video from an analog mixer.

I found these:
Hauppauge Win TV USB-Live2-videograbber
Hauppauge Impact VCB - Video capture adapter - PCI
Terra Tec Grabster AV 300 MX (software = magix, so that might be crap)
Elgato Video Capture

The matrox has been a PITA for me so far. Mostly boils down to them not and never planning to support El Capitan. Just bought a MBP off of craigslist specifically for this purpose, but now have to find a way to get Yosemite since Matrox isn't supported in Capistan. Hopefully the brick and mortar Apple store has the Yosem installer, because now that Capi is out they've pulled it from the app store :bang:

Seems really strange that they've officially stated that they have no intention of releasing drivers for either Windows 10 OR El Capistan. On one hand they're still selling the devices and on the other they've stopped supporting compatibility of said devices. Wild. Really makes me consider looking into different hardware just on principle.

Hi all, I'm joining the search for a good capture solution! I'm looking for a way to record the video output (obviously), but ideally also a way to feed the video into a mapping software (LPMT) to map it for projection to complex surfaces.

Ideally I'd like to feed the video to a suitable CRT monitor and film it in glorious HD, but I'd like a solution which could also easily be adapted to just record straight component from the synth, for situations when a crazy camera setup is inconvenient. For the monitor+camera solution, I think I'll hack my Nikon D7000 SLR to output clean HDMI without the menu overlays that can't be removed by default, and to get the output into the confuser I'm considering a Magewell HDMI dongle (link). To capture component directly, I guess this thing could feed the synth output into the Magewell dongle.

To make matters worse, I am for some reason doing all this on Linux. While some of the Blackmagic things work on Linux, it does appear that they use their own software, not v4l2? Any comments on this? I would need v4l2, as that's how the video would get fed into LPMT.

Moreover, I'll be using Veejay to mix videos that go into the synth for processing, and I imagine it could be very interesting to feed the output back in there (also v4l2).

Any thoughts on this? Have anyone here tried the Magewell stuff? They have some very interesting products, including PCIe cards that would be great for dedicated video machines.

Just used this thing on a shoot "Atmos Shogun"
https://www.atomos.com/shogun/

capable of recording up to 4K via HDMI input so its able to record whatever incomming stream and saves Pro-Res Quicktime files.

I ended up ordering a Terratec Grabster AV300MX

let's hope it does decent grabs then :party:

the Grabster AV300MX arrived today.
after testing the included software (it was disappointing to say the least)
I downloaded VirtualDub and Virtual VCR.
These gives me way more options and far better video quality.
(output to uncompressed is vital)

I only have to find out how to deinterlace correctly.

I just received one of those Magewell USB3 HDMI cards, and can confirm that it works very well. I haven't assessed the quality thoroughly yet, but it seems fine. It's extremely easy to set up – that is, there is no setup at all. On my Ubuntu machine, it just pops up as another V4L2 device, with absolutely no drivers to handle at all. Really smooth! Next step now is to hack my camera to give a clean HDMI output, but the Magewell also works well with a YPbPr→HDMI adapter.

Also ordered a Composite/S-video→YPbPr/VGA converter box, which I'll use to feed the LZX with madness from a circuit-bent TI99. Fun times!

This sucks. I was recently looking into possibly upgrading to the Matrox MXO Mini for 1080p capturing. No El Capitan support kills the deal. I'll stick with the Canopus ADVC 110 for now.

So my trusty, rock solid Canopus 110 I've used for the past 9 years was returned from a 'friend' all lit up (fried FireWire chipset). Sloppy hotswapping? Replacing it with a used unit from eBay is quite the gamble. Most say 'powers up' and/or 'should work'. Yeh, mine 'powers up ' too! And it 'should work'.

Having a pre- thunderbolt Mac Pro led me to the BlackMagicDesigns Intensity Pro 4K pcie card (the option to upscale is enticing). I've read it has had major issues with its analog ins. My world is all composite video, so this is crucial in my decision.

Anyone using the intensity pro 4K card? Any issues with the composite or s-video ins and out?

Much apreesh!

I'm running a 4k Pci-e, the one that's like $189 or whatever. Never had any trouble with the composite ins, haven't tried the S-video tbh. I really like the card and you can do simultaneous I/O... For instance you can record your video noodling while you're feeding video to process.. It can get a bit laggy but I've had good results with it.

Haven't heard of SD problems

Having said that I'm on PC, not Mac.

My buddy just gave me a PC with a built in capture card for free! Tried it with Virtual Dub and the Panasonic WJ-MX70 I got (for super cheap!) and it is awesome. I'm so happy I have a way to capture somewhat decent quality now.

Ive got the same magewell here and love it for getting HDMI sources into various softwares. But im looking for a good solution to bring in video from a 3trins. Ive used the little crappy composite -> HDMI boxes from amazon (AV2HDMI) but the quality is terrible.

If you find something decent, Im on the hunt for something that will output SD (so there is no scaling) and hopefully with decent deinterlacing + low latency. Hopefully not too much to ask.

I have looked at gefen's COMP to HDMI scalerhttp://www.gefen.com/product/composite- ... ID-2-HDMIS and have almost pulled the trigger - anyone else used this? or any other ideas?

running windows10...

I know a few video synthesists that use this:


Have only seen it in use live though, so can't comment on quality for capture...

Simultaneous video capture - help please!

Post by alexosm » Mon Apr 29, 2019 8:52 pm

Hi, I've been shooting live with three or four eighties PAL broadcast cameras, going through a video mixer, along with live video effects, keying etc. Up to now I've been editing live, to a dvcam deck, and then digitising later from the deck.

I would like to be able to capture the feed from at least three of the cameras so I can refine and edit footage later- rather than a live edit to one DV deck. Ideally I'd also like to be able to play back all the footage simultaneously to four CRT monitors as if it was live. I know I could edit in Premiere like this, but I would like to be able to work with the separate monitors in a live control room style edit if it's possible.

The only suggestion I've had is four PAL to SDI convertors going to a Blackmagic DeckLink Quad and then to a computer. It doesn't seem very elegant, would that be reliable?

I was considering using a CCTV capture device, for multiple cameras. Has anyone tried this? I can't really spend more than $1k-1.5k

thanks for any suggestions!
Alex

Another that came up per the LZX community is the Kramer VP-410 Composite Video & Stereo Audio to HDMI Scaler.

I've been having great results with averMedia stuff.
For HD 1920x1080 i use this
it records decent quality designed for youtube gamer channel stuff.

I also had pretty good luck with the 4K recorder- only this one does not have "standalone mode" and requires a pc to operate the capture process via software.

I was thinking of avermedia for some time, and it's not clear how well their stuff works with mac. Did I get it right that the first one is ok with any os?

that first one works completely in standalone mode and then comes up as a USB drive so its most likely fine with a Mac or PC.
as for The second 4K one i'm not sure if they offer a Mac Version of the software
