- Overview of the Blackmagic Design Smart Videohub 40x40.
This is a 40-input, 40-output SDI video routing switcher, which allows redirection of any video source to any video destination, and supports SD-SDI, HD-SDI, 3G-SDI, and 6G-SDI.
I didn't make it clear in the video, but my one wish for the SVH is that it could allow you to see video sources without routing them. Currently, to view a video source it has to be output to a destination, and you choose that destination to view it. In my mind it makes at least as much sense to have the option to view by source as well.
Hi Doug! This is Michael who stopped by with Marty a few weeks back. I was looking for some tutorials on how to update the firmware on these and go figure, found your channel!
Great video. We're in the process of getting the same hub. Very helpful video.
Glad to help. I wish videos like these were available when I started buying my gear, so I figured others might be able to benefit from my experience.
Thank you so much sir for your packaged information.
Thank you for this great video !
Hey Doug, quick question for you. I have an esports center and want to get this device to switch between different PCs. Will I be able to access the video feed through OBS software so I can stream the content to twitch, TH-cam, etc.? Is each source accessible in OBS? Thanks for your time.
You'd need video capture devices to get video into the computer so OBS can see it. Since the Videohubs use SDI, you'd probably want to find an SDI capture device like the UltraStudio Mini Recorder 3G (which requires Thunderbolt), or you'd have to use converters to get the SDI signal into an HDMI input.
Nice video & Thanks :)
Can you put labels on a output destination? I definitely would need 2 cause I would want to run everything thru it and each camera would need 4 destinations
Yes, you can label the destinations.
But if you're going to always send the same sources to the same destinations, a video distribution amplifier might be a better choice.
@@djp_video I meant like an overlay on a monitor displaying source names? I really need to find out who makes that lcd rack mounted name thing
No. It doesn't modify the video signal in any way -- it is just a signal router.
to get the knob encoder to go in numerical order, just put the input / output number at the start of the name
01 - Cam 1
I had actually thought of that, but I do like having the option of being able to scroll to a source/destination by name, in case I can't remember the channel number.
Hi Doug, I'm looking for a videohub for my studio and would very much like your opinion on which one to buy. I've been looking at the BMD 20x20 ans the new AJA Kumo 1616-12G. Any thoughts would be very much appreciated :)
Both are great products. Select the one that has the right features that you need and fits within your budget. I went with the BMD because of cost and because they have the LCD screen so it's easy to see what video is getting routed where.
Great and informative video on the BMD Smart hub 40x40. Your new setup looks more or less like the way we are wanting to go building a 4K rack…
Is there any possibility please of you making a diagram/flow chart of the wiring setup you have used in your updated 4k rack system?
I would be extremely grateful if you would be so kind if it is at all possible?
You can infer how everything is connecting from the list of inputs and outputs as seen in the video starting at 6:25. The 'Converter' inputs/outputs go to Decimator MD-HXs, Optical go to a BMD Optical Fiber converter, and anything else referenced (Aux In/Out, TV/Projector/Engineer/Director outputs, etc.) just go to a 48 BNC patch panel on the back.
I was just being slightly lazy ;-) and many thanks - great videos by the way - do please keep them coming?
Can you create macro functions with these buttons? So one press triggers off a group of commands when pressed? eg when button 8 is pressed every monitor connected will receive A CAM feed only
no with just the hardware this may be possible buy making macros through companion
Thanks for the helpful video! One question, will you be able to customize and reorder the source and destination list?
For example: Let's say your destination TV1 and TV2 is in input port 41 and 42. Would I be able to make a customized routing page where TV1 and TV2 shows on top of the list to be destination port 1 and 2?
Not with the current software.
@@djp_video Thanks Doug! Enjoying your helful videos as always.
Hey Doug some one selling the 40/40 12g sdi mix format routers for 4700 is that good bran new in the box . It’s that wroth it my friend.
$4995 is the normal retail price. You decide whether it's worth it. Be sure to check to see if the warranty will still be valid.
Hey Doug, thanks for sharing all your thoughts. We recently bought a SmartVideohub 20x20 and its very noisy. We will have to use it in a mobile rack a radio studio to livestream the radio show. So the sound guys will kill me when I power on the SmartVideohub. Do you know if the 12x12 is more silent or if there is an option to silent the device by replacing a fans e.g. - Thanks for your opinion. Best regards, Rob
I haven't personally used the 12x12 so I can't really say for sure. Sorry!
Doug Johnson Productions Are the fans of your 40x40 making a lot of noise too like the 20x20?
Hey Doug, can you send multiple inputs to one output? Say I have 3 cameras in, and 1 output going to an input on a DeckLink 8k? Many thanks.
No. You can do a single input to multiple outputs but not the other way.
Hi Doug, great useful content as always. are you able to produce a quick video explaining the master control remotes (if you have one). I want to know if you can configure a remotes to only change one output on the matrix, without the use of the take button. for example for a CCU desk, or lighting engineer to change what feeds they get on the fly during the production.
Thanks
The Smart Control can do this for sure. I'm not sure about the Master Control. I don't own either one.
Hey Doug I recently purchased the 12x12 and am in need of help installing and setting up. Can we connect?

Great Video! Can you route a single input to multiple outputs, using it as a distribution hub of sorts?
Hope Point Church Media Yes
I suppose if you put the input number first, it would sort by that ;-)
Thanks for the helpful video. Super curious what the xbox controller is used for?
It controls two of my cameras... see this video: th-cam.com/video/OWJWzh1LBmI/w-d-xo.html
Oh- I just found it- Camera control! brilliant!
Just how loud are the Smart Hibs? I have a 16x16 and a multiview 4 port and i can't believe how much louder they are than any of my servers. Before i go through the trouble of sending them back i was curious if you had a real world opinion on just how loud they are? Thanks!
They are fairly loud. But it hasn't ever been a problem for me. As you've seen in my videos, my rack of equipment is sitting right next to me and it isn't audible on camera. We've also never had any problems with operators not being able to hear the director, even though the fans are audible in the background of the intercom system.
Okay thanks thats what ive been told as well. know of any alternatives i'm going to get (i need) a 20x20 and before i stick with BDM just wanted to know if you had any good alternatives. thanks again
There are alternatives, but they're quite a bit more money, especially if you're doing 3G or 6G. So it largely depends on your budget.
Hello,
Small question, is it possible to duplicate a signal with the videoHub?
Yes, you can send any input to as many outputs as you'd like.
Hi! Nice video! Does the smart videohub keep the tally signal through sdi? Thx
Yes. It preserves all SDI ancillary data.
great news for me ;) thx :)
Dear doug, I want to ask you that how many master control pro hardware panels can we attached with smart video hub 40x40 router?
I'm honestly not sure. I've never run into a limit.
@@djp_video from where I can confirm this?because its not mentioned in any tab for website aswell.
I didn't see it in the manual either. Try reaching out to Blackmagic Design Support.
@@djp_video dear doug can you suggest any low budget ip based communication system. I am looking for something like clearcom eclipse but very low budget. I just need 8 to 10 control panels.
Take a look at Studio Technologies's Dante intercom stuff.
Is there anyway to change from SDI A to SDI B or vice-versa? Sorry, I realize this is a 2 year old video, but I'm hoping you've got some wisdom here.
The Videohub will pass SDI A or B, but it won't convert between them. For that you the least expensive products you can use are either the Blackmagic Design Bidirectional SDI-HDMI Micro Converter, or the Decimator Design MD-LX.
Doug Johnson Productions is it possible to support live titles, lower thirds, overlays, over-the-shoulder graphics, and bugs. though the videohub 40x40?
The Videohub is just a signal router. It doesn't do any processing to the video. Whatever goes in is exactly what comes out.
Doug Johnson Productions other solutions? Propresenter?
How can i Factory Reset the 40x40?
There doesn't appear to be an easy way.
Can you route a single input source to multiple outputs simultaneously? i.e.:
Input SRC 1
to
Outputs 1,2,3,4,5,6,7,8,9,10 Or any variation of outputs (to view the same images on all multiple monitors?)
Trying to use in a nightclub for multiple in house monitors. Would like to assign different monitors to different input sources or have them all the same.
Thanks!
Yes. Any output can receive the signal from any input, in any combination.
Can you input at one resolution and output at another?
It doesn't do any sort of scaling or frame rate conversion. Whatever signal format goes in is what comes out.
Doug Johnson Productions
So inputting to an ATEM ME1 video switcher I still need all the inputs to be the same? Correct.
That is correct.
If you need to do signal conversion, take a look at the Decimator MD-HX ( djp.li/mdhx ) or one of the BMD Teranex products (AV or Express).
will it do 3G level A?
Yes, it does.
I thought the 12g did but the 6g didn't. Can you post a video to confirm?
Yep... th-cam.com/video/uYPDiJ75Quk/w-d-xo.html
Can this hub save presets?
Internally, no. But the software that runs on a computer can.
Doug Johnson Productions so do you just need to have the software running? Or do you need to load the software and load the presets? We use a production truck for sports and I'm just now realizing that every time we go for a shoot, I now have to re-Route every single cable every single time we turn the truck back on.
Two things:
(1) The videohub always remembers its last state when powered up, so if you're doing the same event over and over again you wouldn't have to load any presets or re-patch. It would just remember how it was last configured before it was powered down.
(2) Storing a preset it is done by loading the PC/Mac software, clicking a button to save the preset to a file. Recalling that preset is done by loading the software, then opening the file you saved previously. After you've saved or recalled the preset the software doesn't have to continue running.
@@djp_video I've noticed that saving and loading a preset actually doesn't do anything at all. Is there a reason for this? I want to save a loadout to recall when we change setups/events, but everytime I re-route and save it, I load up the old and nothing changes. Currently updated to the latest. BM Forum search brings up a lot of the same questions with no answers.
Just wondering if you had found a solution. Thanks!
@@WarriorNetwork The "presets" that are supported by the software are just then names of the sources. It doesn't include source->destination routing information.
And tally’s
Blackmagic tally does pass through properly.
@@djp_video hey I do love your videos cause we are like doing the same kind of thing… can you make a not to long video showing hyperdecks locking to time code? This is very important for my workflow cause all of the audio is multi tracked and much more than 16 channels sometimes hundreds to a daw that can receive and send time code
@@djp_video I just need to see how tight they lock together… the daw is pretty tight way less than a frame it’s phase accurate but probably not on the video end
HyperDecks don't lock to timecode. With the newest models you can connect a timecode source and it will embed that in the metadata of the file, but that's all it does -- it doesn't alter timing of the device in any way so they can still go out of sync. And the timecode input is completely ignored during playback.
Have you seen my video on genlock/timecode/wordclock? th-cam.com/video/yUn8mMQ0JGg/w-d-xo.html
@@djp_video yes I did see almost all of them … I saw a blackmagic promo video saying that they can lock to tc for post production sync
