Sofie: open-source web based system for automating live TV news production

Very cool. You can even control the prompter using a Joycon!

Cool, going to create my ai tv station.
stephen_g•6h ago
Very cool they decided to build this and release it to the world instead of just buying an extremely expensive commercial system. The backend play out server is CasparCG which is also open-source [1] (they run their own fork, for stability reasons I expect).

Another similar related automation system (shares some parts and libraries) is SuperConductor [2].

Joel_Mckay•4h ago
Looks more practical, as when dealing with hardware access C/C++ is the only way to get the latency issues into tolerable playback stream formats.

Cool that it also supports OBS Studio by the way =3

chriscjcj•6h ago
As a live television newscast director in a major market, I would be very interested to see a feature comparison between this product and its main competitors: Ross OverDrive, Sony ELC, and Grass Valley Ignite.

Due to the substantial complexity of these automation systems, they tend to have a lot of inertia. But if anything could drive a station group to make a change, the "free" part can be effective.

I did take a look at the supported hardware (1). I think that's the pain point for many shops. Free open source production software is great, but being forced to choose form hardware products you don't prefer is a pretty tough tradeoff.

Historically, I suppose that's been one of FOSS' big challenges.

(1) https://nrkno.github.io/sofie-core/docs/user-guide/supported...

delfinom•5h ago
That's the thing though, this isn't really "free" software as much as open. NRK is funding it and created it for their use, that's cost money. They spent money on supporting the hardware they clearly had and wanted to for their production. Any other user with their own setups they want supported will have to spend money on developer time as well.
simonw•5h ago
Free software has a well established meaning at this point, and it's not "didn't cost any money to produce".

Looks like this is MIT licensed https://github.com/nrkno/Sofie-TV-automation

delfinom•5h ago
I disagree with said meaning because it's been established by leeches trying to sound like they aren't.
glass-z13•5h ago
Free software, libre software, libreware sometimes known as freedom-respecting software is computer software distributed under terms that allow users to run the software for any purpose as well as to study, change, distribute it and any adapted versions.
simtel20•5h ago
You are trying to establish that the financial meaning of free software is the primary meaning, while the freedom aspect has been the primary meaning. You would do better to change your focus to searching for false claims of "no-cost" software or something rather than trying to undermine an established meaning that is already understood and widespread.
Joel_Mckay•4h ago
Everyone starts out as a leech, as FOSS offers you freedom to behave in such manners.

However, unless you support the community in your own way, than people are just along for the ride.

Remember to try and be kind... even if you don't agree with your peers =3

Joel_Mckay•5h ago
Indeed, people usually contribute to FOSS by supporting the authors group or nonprofit directly, and contributing features and bug reports/fixes.

However, from a maintainability standpoint it is important that a project solves their own needs first. The "eat your own dog food" advice is important, or groups end up fragmenting a project into every pet use-case.

Best regards =3

rjmunro•5h ago
It was mostly developed for NRK by Superfly.tv. They are available to extend the system to other hardware or customise it in other ways if the broadcaster doesn't have the expertise to do it themselves. It's already used by several other broadcasters, for example, the BBC use it for their Newsround program: https://www.linkedin.com/posts/ryanwmckenna_great-to-see-new...
sitkack•4h ago
It looks like great support (Blackmagicdesign) for building a small broadcast studio from scratch tho.

I could see BMD embracing this. There are lots of studios that are not commercial broadcast that could really use a system like this.

Isn't one of the problems with hardware support is that hardware vendors have agreements with the competitors you listed?

Computers are fast enough now that once you can get the signals into a machine, many of the special functions that previously required dedicated hardware can now be run in software? With proper timing signal distribution of course.

Seems like 12G SDI to SFP+ would enable server class machines to subsume most of the special function hardware.

randall•2h ago
bmd is in a decent position to help with this. making davinci be the nle that ties into this like avid / airspeed or whatever ppl use now, seems pretty cool.
chriscjcj•2h ago
Disclaimer... I am a director and not an engineer. I can only give you my relatively limited understanding....

> It looks like great support (Blackmagicdesign) for building a small broadcast studio from scratch tho.

Agreed!

> I could see BMD embracing this. There are lots of studios that are not commercial broadcast that could really use a system like this.

Also agreed. Black Magic definitely makes a lot of reasonably-priced and very capable gear. They're not a major player in the TV automation space, but perhaps with the help of Sofie, they could make inroads.

> Isn't one of the problems with hardware support is that hardware vendors have agreements with the competitors you listed?

That's not a topic I'm knowledgeable about. It is my understanding that most shops who have a particular vendor's automation platform will also have that vendor's hardware running at its core. In all the shops I've seen, the switcher that's controlled by the automation system is made by the same company. Or if its another vendor's product, it's sold and provisioned along with the automation system when its purchased. Other stuff like audio mixers, robo-cam products, clip players, and CG/graphics platforms can be from other vendors.

For audio, I think that would be a relatively easy lift with technologies like Dante. However, in most TV stations, you're going to need to literally plug upwards of 100 HDSDI video cables into a piece of hardware so that those sources can be switched to on TV, mixed and keyed on multiple mixed-effects banks, and viewed on multiviewer screens in the control room. I don't know that a regular-ol' PC has what it takes to take in and simultaneously process that amount of video. But just because don't know about it doesn't mean it doesn't exist. ;-) Just haven't seen it yet.

I don't know the TV stations requirements, but you can maybe have 10 interconnected servers that manage 10 HDSDI flux each (and can send them on another if required for processing) ?

Sofie drives the matrix (black magic videohub for small ones like the 120 squared, but ours are 1000+ which black magic won’t do), the audio mixers, the video mixers, the graphics and by machines (Caspar), etc. your mixers don’t need that many inputs - a typical one might be 24 or 32 inputs with a few ME banks.

All these devices use standard protocols, or it’s just a new plugin for sofie ti drive it.

Of course increasingly the industry is using 2110 on spine and leaf networks rather than SDI. I don’t know if there any COTS mixers aside from the vmix/obs level, I believe some 2110 controllers will provide video matrix style interfaces. Nmos seems challenged in this area from what I hear.

I’m a big fan of the Richard Cartwright view of asynchronous signal processing

https://creativecow.net/matrox-video-announces-nab-2023-line...

But I don’t think it has the traction isn’t deserves. Too many people in the industry are still wedded to ptp timing their packets to arrive in the same 30us windows.

basch•4h ago
I fall pray to this often. Internal complexity and growth over time lead to great giant feature charts and comparison matrixes. But sometimes you just need a tool that gets a job done.

It's one thing for something simple to not be a drop in replacement. But simplicity and minimalism can also be a virtue. Can this complete the task in an environment designed around using it?

randall•2h ago
how are you still a director??? i miss tv fondly but the pain they inflict on everyone and the hours / pay / etc make the best people bounce.

someone on hn surely could use their talents for good elsewhere haha

chriscjcj•52m ago
Thank you for the vote of confidence. :-)

I do ask myself that sometimes. It sounds weird, but I think it's what I was put on this earth to do. Yes, it is a cruel industry at times and pain is indeed inflicted just as you assert. I guess I'm just built for it. And I've been doing it for so long that I've built up a really thick skin and I'm just not that fazed by its unpleasant aspects. I can honestly say that it's a fun job. It's the job I always wanted when I was a kid and I still absolutely love it. (I'm fortunate enough to be compensated at a reasonable level, so that helps.)

People think it's stressful and I suppose it is. But the nice thing about it is that when the newscast is over, I'm completely done. And I have the luxury of knowing, down to the exact second, when that moment will be. I don't take my work home with me. There's nothing to stress out about (until the next day.)

Another thing... unlike an airline pilot or a surgeon, no matter how poor a job I might do, no one dies. That's kind nice too. :-)

meteorjs' an interesting choice ...
codetrotter•6h ago
Meteor got a lot of attention and hype on HN a few years ago.

Looks at Wikipedia article

Well, 12 or 13 years ago probably actually.

rjmunro•5h ago
According to Google Trends meteor js was popular from about 2012 to 2018. Sofie was started in about 2018, so when Meteor was established enough to have all the kinks worked out, but still popular.

Can you write real-time shaders in it?
rjmunro•5h ago
That's not what it does. You would have your real time shaders running on a server somewhere, and Sofie would activate them at the right moment in the show.

It's a tool that lets you drag and drop news stories in to a rundown and it will automatically play them. The news stories may have parts that are read from a teleprompter, parts that are pre-recorded video, live parts from outside broadcasts, interviews, graphics that need to be shown etc. Those are mostly provided by services or hardware that Sofie controls, not that are part of the show. Sofie is an automation tool.

Ruby code is always a joi to read.
bee_rider•2h ago
Is joy vs joi a Ruby pun of some sort?
hiatus•3h ago
How does this handle things like replays that are queued dynamically during airing? For instance on a talk show there may be occasions where the host wishes to replay a section of a guest interview or to pull up a clip to play while talking over it. Would the operator override an existing Part or updating a piece in a part? Typically this is handled live with EVS.
myself248•2h ago
From a skim of the docs, it looks like those are handled as "adlib pieces", and can be pulled from what's currently playing or from other buckets.
kfarr•1h ago
May seem a bit niche but man I wished we had this 20 years ago when trying to start a student TV station on a budget. The pro tools at the time were ridiculously expensive.
