OBS v21 Update – Scripting, Audio Overhaul, Multiview + More!

What’s up guys! Welcome back to the
Gaming Career YouTube channel. This channel is all about learning how to
livestream and create content within the gaming niche. Today’s video, we’re going
to be looking at the latest version from our friends over at OBS and that is OBS
Studio version 21. This is actually one of the biggest updates that OBS have
released in recent memory. Apparently there’s been 35,000 lines of new code
written by 35 different developers so our thanks as always goes out to the
open source community that helped build this great software. And some of the
features that we’re going to be covering in this video and I’m gonna have to look
at my notes to make sure that I don’t miss any, scripting has been implemented,
multiview, a complete overhaul of audio mixers including a surround sound
support and audio ducking, you can also relable your audio sources now, they’ll
be scene specific transitions, vertical layout for portrait monitors and finally
a couple of new themes. We’re going to covering some of those in this video, so
let’s jump in! So when you open up OBS it should
automatically notify you of the new update but if it doesn’t just come up to
the help menu and click check for updates and we should be all set.
The first thing that you might notice is that OBS’ default theme is now set to
dark. It used to be light and you had to
change it to dark if you wanted it but now dark is the default. So the first
feature that we’re going to be covering is scripting. This is basically using
either Python or Lua, you’ll now be able to quickly extend, automate or add
features into OBS studio without having to recompile the OBS software or build a
native plug-in module as you had to previously. OBS themselves have included
some example scripts to get you going but I think the real benefit of this
scripting function is going to come as more developers write scripts that
you’ll be able to download and use to enhance your OBS experience even further.
One of the included example scripts is a countdown timer which you can use to
count down to your stream starting. In a previous video on this channel we’ve
covered how to set this up using an external program, but now we can do it
completely within OBS, so let’s take a look. Now how this script works is it
sets a text source to act as a countdown timer when the source is active, so the
first thing we need to do before we open up the script is we need to create a
text source. I’ll quickly create one now called countdown and just set some basic
font style and sizes quickly, but we can always come back to play with these more
later if we need to. Next we go up to the Tools menu and select scripts. A new
window opens up and we can see that we currently have no loaded scripts yet so
let’s add one by clicking this plus icon. Here we can see some of the example
scripts that OBS have included in version 21, so let’s just select
countdown.lua. If you click on the script you’ll see a brief description of what
the script does as well as some options that we can use to configure it. First we
can set the duration in minutes, then we can select the source that we want to
actually use so this is the text source that we just set up. And finally we can
select the final text that we want to show when the countdown has finished. We
also here have an option to reset the countdown if we’d like to. Now it’s
important to note here that the countdown starts when the source is
active, so what I would do is when I’m starting my stream is deactivate my countdown source just by clicking this icon here and then when I
start streaming I’d reactivate it so the countdown timer starts. And that’s it
that’s how simple it is to add a countdown timer using the new scripting
function in OBS studio version 21. Hopefully you can understand the kind of
possibilities that this new scripting feature will allow once some more clever
developers get their hands on it. I really like this feature and I can’t
wait to make some videos on some of the cool scripts that are going to come out
of it. I’d also recommend playing around with some of the other example scripts
that OBS have included, there’s an analog clock one, an instant replay script and a
URL text script all included. The next new feature that we’re gonna be looking
at is multiview, which if you’ve ever seen a control room for a TV show it
might look kind of familiar. To enable multiview we go up to the
view and then you can see that we can set up multiview to either take up a
full monitor, which is super useful if you’ve got you know second and third
monitors to choose from or we can set it up just as a window. I’m going to set it
up as a window because it’s much easier to demonstrate. Multiview allows the
ability to view the preview and program screens as well as eight other scenes at
the same time, so you can see exactly what will show up on each scene and then
you can switch to it just by clicking on it, or if you’re running in Studio mode
you’ll need to double click on it. Now this is probably more aimed at advanced
users and people running you know complex setups with many different
scenes but it’s a heavily requested feature and it’s really going to help up
the production quality and make it a lot easier to manage the stream, since you
take out the guesswork of what a scene will look like. Imagine running an event
where you have multiple cameras filming the action. In multiview you’d be able
to see exactly what each camera is filming and then swap the stream to the
camera that has the best shot. It’s also worth noting that if you have more than
eight scenes you can blacklist certain scenes from displaying in multiview
just by right-clicking the scene and unchecking show in multiview. So you can
choose your eight favorite seems to show up in multiview. Next we’ll look at the
audio meters and some of the more observant viewers might have already
noticed that the audio meters down below have changed. Now quite a lot has changed
down here so I’m going to do my best to break it down into smaller sections.
Firstly, the audio meters now behave much more like peak program meters that
you might see an editor software like Premiere Pro or audio
software like Audacity. Each audio source now gets its own meter with mono, stereo
and surround devices now showing a meter for each channel. And yeah you heard me
right, OBS is now supporting surround sound streaming. Certain platforms do and
don’t support it but I’ll probably do a much more detailed video about that later.
Now having individual channels and being able to monitor them, this allows you to
much more clearly see if your audio is clipping and you can set your audio
levels accordingly. OBS have written an amazingly in-depth guide all about these
new audio levels, channels, indicators and I just wouldn’t do it justice if I was
just reading it out, so I’ve linked it down below. I’ll quickly go through the
most basic level of setting volumes but I absolutely recommend going and having
a look at this article if you want to set up your audio properly. Now as you
can see each volume meter is made up of three different zones,
there’s the green, the yellow and the red. Firstly you want to avoid any sources,
any audio source at all from reaching the red zone as this can cause clipping
which sounds pretty horrible to your viewers. The yellow zone is ideally where
you want your own voice to sit and that’s not just your own voice but also
the voices of any of your friends on Discord, Teamspeak or Skype. Basically the
yellow zone is where you want the voices to sit. Finally the green zone is where
you want all your other sounds to sit things like background music, game sound,
alert sounds etc etc. This way your voice will always be heard over anything else.
One last little but again highly requested change to the audio meters is
that you now can rename your audio sources just by right-clicking them in
the mixer. This is particularly useful for those people that have USB
microphones that have been named something strange by Windows. Hopefully
this new audio meter interface is going to make it much easier to set up proper
audio levels as well as be able to diagnose any issues. A common example is
stereo devices only playing out of one channel and you couldn’t used to be able
to diagnose that within OBS because it only showed you one meter, but now stereo
signals will show you a left and right channel so you’ll be able to see you
know if one of your audio devices is playing up. Whilst we are on the topic of
audio, it makes sense to cover the side-chaining or audio
ducking feature that OBS has added in version 21. Now audio ducking is when an
audio source can automatically lower its volume when another source starts
playing. So the most common use case when you have background music or game
music playing at a certain volume, but as soon as you start speaking the music or
game volume decreases temporarily to create room for your voice. When you stop
speaking the volume of the music or game volume increases again. It’s probably
easiest for me to demonstrate with an example. So since it’s my music that I
want to be applying the audio ducking to, I click the little cog next to that
audio source. Next I’m going to click filters and add a compressor filter to
my music source. Now I’m not going to go into loads of detail on these settings,
as they’re pretty specific to me and my setup, but to get a general feel of what
audio ducking can do, I’m going to set my threshold to match what my music volume
is playing at and I’m going to up my release to the maximum of 1000
milliseconds. Finally I’ll select my side chain or ducking source to be my
microphone, as this is the audio input that I want to be ducking for. Now let’s
see and hear exactly how this sounds, first of all I’m going to swap to my
desktop mic and start playing some music. Now what you should notice is as soon as
I start speaking the music volume has gone down and as soon as I stop speaking
the music volume will come back up again. Again when I start speaking the music
volume sound goes down. This is audio ducking! Hopefully that was all understandable,
I’ll likely do a much more detailed walkthrough of this feature in a future
video. The last feature that I want to cover quickly the OBS have included into
version 21 is the ability to add scene specific transitions. What this means is
that you can set a transition to always happen when you change to a specific
scene. So for example if you wanted to always have a luma wipe that takes 750
milliseconds to complete, when you swap to your game scene, all you have to do is
right-click the scene, click transition override and select the transition and
time in milliseconds that you want. Now whenever you swap to that scene it’s
going to use that transition. You can of course have every single scene setup
with a different specific transition. Again it might seem like a super simple
feature, but for broadcasts when you always want to have you know a sting or
like a certain transition when you’re going to a scene it really helps add
continuity to your stream and make it look more professional.
They’ve of course added other little fixes and new features into the software,
but I think that about wraps up the main features that I wanted to cover in this
video and again I would like to say thank you to the OBS developers. A
massive community of people helping build this amazing free software for us
all to use, so thank you OBS devs! I hope you’ve enjoyed exploring some of the new
features of OBS with me. If you have enjoyed the video please do give it a
thumbs up and if you’re new around here please have a look around at the massive
amount of videos that we’re creating all teaching you how to livestream and
create content within the gaming niche. Subscribers I’ll see you in the next
video, peace!
