SLOW MOTION INSTANT REPLAY Tutorial _ OBS Studio Tutorial - Full Replay Buffer Slowmo

Setting Up Multi-Action for Instant Replay Buffer with Elgato Stream Deck

To set up multi-action for instant replay buffer with your Elgato Stream Deck, you need to first understand the concept of speed and frame rate. The stream deck allows you to adjust the speed at which video playback occurs. For example, if you want to play back a 240 fps clip, you need to set it to 50 speed for 240 fps, or set it to 25 speed for 60 fps slow-mo. This flexibility is useful when you want to control the playback of your instant replay buffer.

Another crucial aspect of setting up multi-action is understanding how to save the replay buffer. You need to set the stream deck's hotkey and create a delay between certain actions. The hotkey will activate the replay buffer, and the delay will ensure that the replay buffer has enough time to write data to a local disk. Since you're writing 240 frames per second on your SSD, a two-second delay is probably too much, and one second would be safer.

The next step in setting up multi-action is to create a scene switch. This involves selecting the collection from your actual stream OBS instance and configuring it to switch between different scenes. In this case, you want to switch between the normal in-game OBS scene and the slo-mo replay scene. You can adjust the delay for each scene switch based on how long your clip playback is.

Another important consideration when setting up multi-action is running the stream deck software as administrator. If your portable OBS instance is set to run as administrator, the stream deck software also needs to be set to run as administrator or the hotkeys won't work unless it's in focus. This can be frustrating, especially if certain program launchers and tools don't work properly.

To create multi-action on your Elgato Stream Deck, you need to find a blank key and right-click on it to create a new action. Then, click into it and drag the options from the right-hand sidebar into the scene. You can add different actions such as hotkey activation, delay, scene switch, and more.

Using Multi-Action for Instant Replay Buffer

Now that you've set up multi-action on your Elgato Stream Deck, you're ready to use it for instant replay buffer. To do this, simply hit the hotkey you assigned earlier, which will activate the replay buffer. The delay will kick in after a short period of time, allowing the replay buffer to write data to the local disk.

As the clip playback starts, the scene switch will activate, switching back and forth between the normal in-game OBS scene and the slo-mo replay scene. This creates an immersive experience for your viewers, who can see the instant replay playing out at 60 fps with smooth slow-motion.

To put it all together, you'll need to configure the multi-action on your Elgato Stream Deck according to your specific needs. You may need to adjust the delay based on how long your clip playback is, and you can also add or remove actions as needed.

Tips and Tricks

One tip for setting up multi-action is to test it thoroughly before streaming. Make sure that all the actions are working correctly and that the replay buffer is writing data to the local disk without any issues.

Another trick is to use a consistent naming convention for your scenes. This will make it easier to switch between different scenes during your stream.

Finally, don't forget to have fun with your stream and experiment with different settings and configurations. With the Elgato Stream Deck, you can create custom actions that enhance your streaming experience and provide an immersive experience for your viewers.

"WEBVTTKind: captionsLanguage: enare you a game streamer that streams at high refresh rates do you want to show silky buttery smooth instant replays to your viewers in slo-mo in this episode of stream guides sponsored by nerd or die i'm going to show you how to do exactly that it's a pretty slick workaround and i'm stoked to be able to share it with you today let's take a look at an example let's see it again run it back heck yeah that's what i'm talking about i'm your stream professor eposvox and this is an exciting project that i have been putting out for way too long but i will definitely be using in my streams should i do more pc gaming streams in the future now this kind of effect is best achieved with a dual pc setup you can do it with a single pc setup but it's way more convoluted and you're adding that much more processing and scene rendering workload to your system that i'm not sure i'd recommend it anyway because the performance impact on your game could be pretty wild for this project we need a few things first a high refresh rate monitor in this video i'm using this tiny little portable asus monitor that i reviewed a little while back that is 240 hertz at 1080p next we need a capture card that can capture all 240 frames or 125 frames or what have you you can use any high refresh rate you want so 144 hertz like my back monitor 165 hertz whatever your capture card can actually pass through and capture that's a high refresh rate that you have to use go for it for the capture card we're using the avermedia live gamer 4k but this will work with the live gamer 4k or elgato's 4k 60 pro mark ii and we're utilizing these two specific cards because of two things one they actually capture and can you know record all individual frames of that high refresh rate signal so if i'm passing through 240 hertz i can actually capture 240 frames per second both of those capture cards will do it the older 4k60 pro mark 1 kind of struggles with that and the avermedia live gamer duo or the live gamer ultra both can pass through high refresh rate signals but do not capture every single one of those frames secondly we're using these cards because they both support multi-app capability meaning that you can add them to multiple programs at once elgato's 4k60 pro mark ii supported this out of the box and then they added multi-app to the hd60s and the hd60 pro well avermedia launched their live gamer duo with this capability and have since also added it to the live gamer 4k which means we can have this running in multiple obs instances or obs and streamlabs obs if you like without really any issue which is exciting we will also need two instances of obs running you can do this with basically the exact same setup in streamlabs obs but i'm gonna be focusing on base obs studio here but the first instance that we're using will most likely need to be obs studio itself to set up your hardware of course do what you would normally do plug in your gaming pc into your hdmi input on your capture card and hdmi output to your high refresh rate monitor and you're good to go if you're using a monitor that does not support hdmi 2.0 and thus can't do high refresh rate over hdmi only displayport then you will have to likely use display cloning out of windows in order to get hdmi run to your capture card or you can use the level one text repeater which will pass through a displayport signal but also output hdmi which is pretty neat but doesn't support adaptive refresh rates or adaptive sync i'll have a full video on that coming soon software wise we need to set up our first obs instance and this will be the instance that's actually recording our uh our slo-mo so to speak so for this i highly recommend using a portable instance of obs instead of a main one because you can launch two instances of obs by middle clicking on your taskbar entry uh approving whatever prompts and then it'll say are you sure you want to launch obs again hit launch and then you can switch profiles but this can cause some corruption and all sorts of weirdness i don't recommend it i recommend downloading a fresh copy of obs from their website choosing the portable zip option extracting that to some folder i use c i use c programs obs portable and then make a shortcut to the obs64.exe modify that shortcut by going to properties and under target add dash dash portable to the end of the shortcut target and that will run it as its own version of obs something to keep in mind is that plugins and things like that will also be need will also need to be installed to this portable instance as well and you'll need to set up new profiles and scene collections for it so if you have any plugins then you'll have to copy over the data and obs plugins folders over to this one as well in this profile go to your settings in your video tab and then change your resolution to your desired the actual resolution that and frame rate that you're gaming at so if it's 1080p 240 you do 1920 by 1080 and then under frame rate to get 240fps you actually go to fractional fps values and do 240 over one if you're doing 144 fps 144 over one and so on i guess i'll go on and note here that you can actually do this at 60fps to slow-mo down to 30fps if you stream in 30fps but most people these days don't for game streams so whatever now under output go to recording make sure you're under advanced output and use ideally in vince but use your graphics card encoder ideally you have invinc or quick sync or something available that can actually do 240fps doing this in x264 is going to be a little goofy and we're just doing a high quality recording so worrying about doing x264 is a waste of time just do invinc i usually set it to a cqp value of 18 that's a fairly high quality recording and uncheck all the extra options like psycho visual tuning and look look ahead because those just add extra load and we're not worried about that right now you can also set your audio to 320 kilobits per second for the best audio but that's not necessary now set your output to go to a specific replays folder not a folder that all your other recordings go to it must be its own replays directory and that'll be important in a minute now add a source for your capture card uh for both the live gamer 4k and the elgato 4k60 pro in order to get all 240 or 144 frames that you're actually passing through to capture under your video capture device settings you go to custom set your resolution and then under frame rate you don't have higher than 60fps as a specific option but just set highest fps and then click ok now you need to set up the replay buffer the replay buffer is essentially the instant replay capability or shadow play capability where it will be constantly recording to your system ram and then you press a hotkey and it will save that to a video so for this go to settings output and there's a far tab called instant replay i usually set this to about five seconds because at a high quality recording it eats up a lot of ram um and then i've reserved eight gigabytes of ram if if you don't have a whole lot of ram available on your streaming pc i actually recommend setting like a cbr recording profile instead of cqp like i just set and set to like say 40 megabits per second and then set like two to four gigs of ram available as your instant replay buffer then go to your hotkeys settings and set a hotkey for the instant replay saving so this is alt equal sign for me but something that isn't assigned to something else that you can use now click start replay buffer and that is going if you wish to actually just have replay buffer launch whenever you open this instance of obs you can also add that to your shortcut for obs as well so after the dash dash portable you can also add dash dash start replay buffer to your shortcut as well and you can even set it to automatically open that same profile and everything else in your shortcut if you like there's a lot you can do with obs shortcuts i would recommend making a custom icon for example i have this obs thinking one i got from the obs discord for this shortcut that way you can pin it to your taskbar next to your normal obs instance so you have both of them ready to go all right now set up your normal stream profile as you usually would for this i'm using a nerd or die stream package kinetic you can check out our sponsor nerd or die at eposvox.gg nerd or die they're currently having a spring cleaning sale you know get rid of all the old stuff clean it out save some money on some stream overlays and upgrade your stream today with nerd or die they have wonderful overlay systems that provide you with webcam frames stream labels for your you know your recent tips and follows and subs and all of that they have stinger transitions and pretty much every project comes with a source file that you can open up in adobe after effects to completely customize to your heart's content and they have one click set up in obs studio so literally setting this up in a profile was i just went to tool scripts loaded the script and click setup scenes and it's ready to go now for this i did actually use that after effects source file to modify the stinger transition because i wanted one that was specific to the instant replay and so i added a bit of instant replay text to the stinger transition for this package in after effects and exported it back out to use as his finger transition here so then we need to make a new scene for our instant replay to exist so for this i clicked add new scene instant replay i added some cool text to just indicate that an instant replay is playing and then i in order to use that new stinger transition that we just made specifically only on the scene i right click that scene go to transition override and choose our instant replay stinger this means it'll use whatever transitions are assigned to specific scenes for other scenes or just the default but whenever i click my instant replay scene it will use the new stinger transition that i just made just a helpful way to help it stand out so viewers know what is going on next we need to add a media source for your instant replay so if you haven't already go ahead and save an instant replay from your first obs instance as this will create a video file that we need to reference and again this should be set to record to its own folder separate from your normal stream vods or whatever now in your instant replay scene add a new media source not vlc media source but media source and find that recent recording that you just made with the replay buffer and add it and enable hardware acceleration for this we will need a plug-in it's called directory watch media this will be very important as i'll explain in a moment but just go ahead and download that and extract it to your main obs instance not the portable one so now that we have this media source added of course if you just leave it like this then it will just replay that same clip over and over every time you activate this scene this is where that directory watch media plugin comes in handy close the properties for your media source right click it in the sources list and go to filter and now you can add a directory watch media filter to that media source and then choose by created newest and now whenever you activate that scene it will instead of pulling up the first file it will pull up the newest file that you have made in that folder which is why your your replays need to be set to their own folder because otherwise it'll be trying to pull up your stream vod while it's happening or something like that so now what will happen here if we're on our normal gaming scene and we transition over to the instant replay scene it will activate our special instant replay stinger and then it will play the most recent file saved in our instant replay folder so whatever instant replay you just saved will be the one that it pulls up we're not done yet however since we're recording our instant replays at a high frame rate we want them to play back in slo-mo that's kind of the gimmick of this video so go back into the properties of your media source and find the playback rate now the math for this will of course depend on what frame rate you are recording at so for example at 120 fps that recording will be 200 times slower than 60fps which means you need to set it to 50 speed for 240 fps you need to set it to 25 speed to play back in 60 fps slow-mo and again you can go further from there for 30 fps and things like that but we want to play back in 60 fps because that's what we're streaming at and then we want it to play back from 240 down to 60 which is 25 or 1 4. the last piece of the puzzle here is a multi-action that i have set up on my elgato stream deck for the switching the scenes and saving the replay buffer all at the same time this is also something you can do in touch portal as well but i'm showing you in the stream deck software here so our multi-action will consist of four things the hotkey to activate the replay buffer delays to wait for things to happen and then scene switching back and forth in obs studio something to note that i keep running into and is really frustrating if you have your portable obs instance set to run as administrator then the stream deck software also needs to be set to run as administrator or the hotkeys won't be sent to that instance of obs at least unless it's in focus that seems to be completely inconsistent for me this is annoying because certain program launchers and things like that don't work when the stream deck software is running as administrator so as long as this is a dedicated streaming pc and a dual pc setup i would just recommend not running your slo-mo instance as administrator in order for your hotkey to work so creating multi-action which involves finding a blank key in the stream deck software and right-click and create multi-action and then click into it here we're going to drag our options from the right-hand sidebar into the scene so first i go to system and drag in hotkey and then enter that hotkey the same hotkey that i have set to save replay buffer in obs instance number one next i drag in from the stream deck category a delay i have this set to two mil two seconds or 2000 milliseconds as that gives it enough time for the instant replay buffer to write to a local disk i'm using a ssd uh since we're writing 240 frames per second uh two seconds is probably a little too much you could probably get away with one i wouldn't go too far less than one just to be safe because it might be annoying if you go to do your insta replay and it's still pulling up the previous file because it's still writing the first one after the delay then we activate our scene switch which is to our make sure it's selecting the collection from your actual stream obs instance and i have it set to switch to my slo-mo replay scene from there i have a delay again of however long your clip playback is going to be so for example if i have my replay buffers at two five seconds and then i play it back at 25 speed that is 20 seconds now i since the clip starts playing during your transition technically so like for example my transition point is one second into my two second tutorial or stinger transition then technically that second cuts off so you need a thousand milliseconds left less but for 20 seconds of playback that's 20 000 milliseconds i have mine set to be a little bit shorter because it cuts off a little bit of that extra stuff at the end where i was reaching over to hit the hotkey anyway so i have mine set to 16.5 seconds but you can set it however you like lastly after that delay is done that means your replay has finished playing out then i have it set back to switch back to my normal in-game obs scene and then with all of those elements together that multi-action is now on my stream deck i'm playing and streaming my game whenever i want to show an instant replay of a crazy moment to my viewers i hit that instant replay button and this happens oh my god they just got murdered that's one two i got two of them let's run it back i guess that was annoying replay going in for the slow and the punch to the face while i get punched by somebody else all right we're getting chased pretty hard already and another trade there you go ladies and gentlemen slow-mo instant replays at a fluid 60 fps available to your viewers with the press of a single button if you have touch portal or a stream deck or some sort of macro solution available pretty freaking awesome i do hope you enjoyed today's tutorial if you want to see more streaming experiments

selecting the collection from your actual stream obs instance and i have it set to switch to my slo-mo replay scene from there i have a delay again of however long your clip playback is going to be so for example if i have my replay buffers at two five seconds and then i play it back at 25 speed that is 20 seconds now i since the clip starts playing during your transition technically so like for example my transition point is one second into my two second tutorial or stinger transition then technically that second cuts off so you need a thousand milliseconds left less but for 20 seconds of playback that's 20 000 milliseconds i have mine set to be a little bit shorter because it cuts off a little bit of that extra stuff at the end where i was reaching over to hit the hotkey anyway so i have mine set to 16.5 seconds but you can set it however you like lastly after that delay is done that means your replay has finished playing out then i have it set back to switch back to my normal in-game obs scene and then with all of those elements together that multi-action is now on my stream deck i'm playing and streaming my game whenever i want to show an instant replay of a crazy moment to my viewers i hit that instant replay button and this happens oh my god they just got murdered that's one two i got two of them let's run it back i guess that was annoying replay going in for the slow and the punch to the face while i get punched by somebody else all right we're getting chased pretty hard already and another trade there you go ladies and gentlemen slow-mo instant replays at a fluid 60 fps available to your viewers with the press of a single button if you have touch portal or a stream deck or some sort of macro solution available pretty freaking awesome i do hope you
