ATEM Streaming FAQ

Streaming keeps being a popular topic for discussion so i have created a new forum for discussion of ways to stream from the ATEM. 

As many people have the same questions it seems useful to have a FAQ here too. 

Q. Can the ATEM TVS H264 USB2 output be streamed live to the web? 
A. This is not directly supported by the Blackmagic software, however 3rd party utilities have been created to enable this functionality. MXLight, and Livestream Procaster both offer ATEM TV Studio functionality. 

Q. Can the ATEM 1M/E or 2M/E USB3 output be streamed live to the web? 
A. As the ATEM USB3 capture appears as a standard directshow capture device it can be used with any standard web streaming compression utility such as Adobe Flash Media Live Encoder or  Ustream Producer.

Hi Tom,Maybe you want to add

Hi Tom,

maybe you want to add MXPTiny (see http://www.atemuser.com/forums/atem-vision-mixers/live-web-streaming/mxp...) as free streaming software.

Yes that app seems to allow

Yes that app seems to allow streaming via VLC. Its similar to MXlight but cheaper and a bit harder to use. 

its good to see the option expanding. 

cheers

web streaming

questions: I guess MX light works good, I presume and can stream multiple streams?

And the next question...Livestream....does it use the TV studio hardware and the USB port,
or do you have to use another blackmagic device?

I do wish to know.
Thanks.

For MX light..it is possible to streams to most sites? Is that correct?

For livestream...you can only stream to there service...and as told...no other device needed.
Correct? (well there site says that, just asking.)

For either what internet device works best....does a 4g service actually work as it states
capable for 2-5 Mbps upload?

As streaming is a important subject....

Yes.  note: but not the New Livestream service - but that works with their own software as you know.

Are you asking the SAME question again?  Umm..  Correct.  It streams JUST to their service.  No other device other than the TVS and a USB2 cable / port is required.

What device works best?  A wired dedicated internet connection with the required bandwidth.  

But... I have run for over 2 hours on a 4G Verizon MiFi hotspot (this was a backup when the conference center's Internet went down due to a big hardware failure).  At the location I was getting 20Mb Up/Down.  More than enough for the stream. But as you know that speed is not guaranteed and will vary based upon local conditions

thanks....you guys are cool.

yes..I did ask the question in different ways..just to make sure...

So I guess the MX light is the only thing that works for most services (except of course livestream, which you need there own free program)

How many of you professionals out there...have great experiences with MX light.
I have seen many postings.....but does everyone get MX light to stream correctly?

It was interesting to here Verizon 4G got 20 Mbps upload...I thought it only did about 5 Mbps upload...
which is all that is necessary anyway.

Another repeat question..but for good reason..Does MX light stream at multiple qualities all at once
like the live stream service does? Like HD, high, Med. and cell---all together at once.

When I sat on the internet committee many years ago (yes I am old!)...I said video and security were going to be the biggest things.
At that time, I was laughed at. When I told Apple and IBM to make video computers and Apple engineers left Apple to make the first one,,The Amiga 1000,
and yes they admitted it was based on the specifications and design ideas I told them. IBM chips at the time were single layered. I told them
mutli-layered and multi media simultaneously! No one is laughing now! Now you know were it all started.

I ALWAYS wonder why the services just don't take one high quality stream and self create the lower onces automatically, or maybe many do??

Thanks again.

I don't personally use

I don't personally use MXLight ... as I do not stream from my TVS - I stream from my 1ME.  I use Wirecast instead.

I know there are many professionals using MXLight - it is considered a very reliable tool from what I hear.  

MXLight can be configured to stream in multiple bit-rates.  

Some services do "transcoding" at the server... where you send them one stream and the server transcodes to other multiple bit-rates for the viewers.  A good example of that is YouTube Live.  Also Dacast.com does transcoding (I've used that to produce streams compatible with iOS).

But Adobe FMLE can't stream 720p50
or is there anyone which can do this

Nothing streams 50p on the

Nothing streams 50p on the web. 

that doesn't mean that FLME cannot take a 720p input, it will re-encode this to a lower quality before sending it to the streaming server. 

Any decent streaming provider should be able to accept one incoming stream and re-encode it to multiple outgoing streams. This worked 10 years ago using QTSS / Darwin so any providers which don't offer this today should be avoided. 

I've has success with wowzer running on an ec2 instance - pretty easy to setup and configure (compared to say Vic+Rat ;) )  Wowzer can re-encode your streams as needed. It should also be possible to configure a wowzer instance to be a stream distributor to send youre stream on to multiple sindication services.

I can believe that streaming has been so slow to actually take off, and that now it has it is being done in such an inelegant way. I really thought that we would have proper multicasting going on by now, but it seems that business pressures prefer the monolithic centralized streaming model, and that attempts to move away from this (such as BBC iplayer's p2p backbone) have been resisted / crushed / prevented.

Do you mean FLME can wor kwith an input of 720p50 or not

I tried it severall times and it will not work with my configuration

Tried it with 720p60 and or 720p50,94 and it works
but all our systems use 720p50 and FMLE crashed and did not store the config

So I just rented an ATEM

So I just rented an ATEM production studio 4k 2 M/E and it appears that there's only a USB 2.0 output? Is that correct? This means I won't be able to capture over USB 3.0? 

So the production SWITCH is the only device with USB 3.0 out?

None of the 4K ATEM units

None of the 4K ATEM units have USB 3.0 ports (or any video capture capability for that matter). The 4K units only have a USB 2.0 port which is mostly just used for firmware updates.

The ATEM Television Studio allows for H.264 capture via its USB 2.0 port but that's the only model in the current ATEM line that has any video capture functionality.

The original (non-4K) ATEM 1 M/E and 2 M/E were the only ones with USB 3.0 ports for video capture (these are no longer being sold, although you might be able to find a used one around). In the early days, a lot of people had trouble with uncompressed video capture via USB 3.0 (in part because some of the USB 3.0 motherboards couldn't really handle the full data rate). But this may have gotten better with newer USB 3.0 computers and updates to the ATEM firmware.

If you need uncompressed video capture, you'll have to take one of the SDI or HDMI outputs from the ATEM into another video capture device. In terms of external video capture devices, Blackmagic sells the UltraStudio Mini Recorder (for Thunderbolt video capture) and the Intensity Shuttle and Ultra Studio SDI (for USB 3.0 capture). And they also make a bunch of different internal video capture cards (the DeckLink line). And of course Blackmagic isn't the only company making video capture devices, there are a lot of other options out there from other manufacturers as well. So there's a lot to choose from, although probably none of these solutions would be as nice as having the functionality built into the ATEM.

Thanks for the reply, that

Thanks for the reply, that was easy enough, got an Ultrastudio and it worked like a charm. 
I do have one more question, I'm still a little unclear about the benefits of having both the Production Studio and the Production Switcher, which is what I've seen in several professional setups. Is it only so that you can do processing in one area and have your input hub in another or are there other benefits, such as up/down conversion and framerate conversion, that the production studio seems to lack?
