[00:00] Hey guys, it's Enraged. Today I gotta edit a clip. I'm actually editing several clips and I figured it'd be kind of cool just to make a video to show you guys how I edit my clips. It's not going to be any like life-changing advice. If you have basic editing knowledge this probably won't really help

[00:14] you, but if you're just starting out and don't really know how to make clips for shorts from full screen content, maybe from clips from the stream or a gameplay video or whatever, this is for you. I'm going to go ahead and hide myself because I don't want to pick up any of the screen

[00:29] here. I'm using for this I'm using Wondershare Filmora 14. I want to say cost about $60 a year and then I pay a little bit monthly like 20 bucks a month for some of their like audio and transitions and other things but that's

[00:43] completely optional. There are some free options out there like I think CapCut is a free option that are very similar to this but for the sake of this video we're gonna be using Wondershare Filmora 14. For first things we need a clip so I

[00:56] I use replay buffer on OBS. If you don't know how to set that up, I would recommend learning. It's really helpful. I might make a video on that myself. So you want to grab your clip here, my clip, I always save two minutes at a time.

[01:11] If you don't know how to use OBS replay buffer, you can always just pull it straight from your Twitch stream as well. well you won't be able to hear my clip just based off of how I have my OBS

[01:25] settings so might be a little confusing but it's not really important to take this video so I always just grab whatever clip section I want wherever I want to start my clip I'm gonna start it here because there's kind of a little drop

[01:40] here which is like an attention grabber and I turn and I read the sign it's a really stupid clip I just say oh we're having beans on Sunday because murder murder murder being but kind of silly kind of fun um and honestly any content so we're grasping at straws today so

[01:55] obviously this is full video uh full 16 9. you want to switch it to 9 16 that's your standard uh aspect ratio for youtube shorts or tick tock glory we're going to do that we're going to go up

[02:08] to file we're going to go to project settings we're going to go to aspect ratio here and we're just going to go to portrait which is 9 16. make sure you're at 60 fps on whatever you're using so so it comes out nice and smooth. Sometimes it'll put it at 25 FPS,

[02:21] you don't wanna do that, but just hit OK, and you'll see it makes our clip smaller, and then we are over here. So yeah, so now obviously we wanna make this bigger, and we wanna keep the two aspects of the gameplay which is the gameplay itself as well as my reaction So this could be if you a YouTuber this could be your model This could be your face cam if you a live streamer

[02:47] Yeah, so how we're going to do that is I'm going to come down here. I'm going to add a new video track. Go ahead. I'm going to control C to copy this. Like up here on this video track, control V. Make sure they're lined up exactly so that the clips play in sync.

[03:00] they're gonna spawn in when you paste it. It's gonna come on top of the other one so there's not gonna be too video here. And always mute one of the tracks, I always just mute the top one just to keep it simple.

[03:12] And then what I do is I come up here and the top one I use as my facecam and I just kinda drag that over to the side. And then the gameplay one for the bottom half of the screen I just drag so it fills the screen. I move it center like so and then sometimes actually in this case I am

[03:29] going to drag up a little bit make it a little bigger and then drag the center so that you get the center of where I'm looking at the game play if you play it through you'll see it's pretty much what I want to look at is centered so

[03:43] yeah and then for the face cam I just always grab it especially really big and and then put it up here and then adjust so that you can see my face it's noticeable

[03:57] but I'm not like cut off or anything like that so now you'll see you'll have my reaction and me talking and the screen one thing I do want to show real quick is when you are sizing up your

[04:09] video if you're using multiple clips like I am in this video you're going to want it to be consistent throughout each scene right so you'll see like from this transition the gameplay and my face

[04:21] are in the same place as it switches clips so the way to do that is once you size up your two clips as it should you um you're going to double click or double click upon the video segment

[04:34] and basically the three settings you want to keep an eye on are these these should be locked together so you should only have to do one of them. So your scale and your X and Y positions. So once you have it how you like it with your first clip you're gonna go to the top one

[04:49] go ahead ctrl c to copy this then go to this one and you're going to ctrl v to paste it. Obviously mine already the same because it's done and then same thing for the x position and the y position. So what you'll see is basically you're just making everything

[05:06] the same and you do the same for the bottom clip as well so here I show you really quick we edit these i just put 100 on that and zero and we just put zero on the slide position right so now you can see this and this

[05:24] are very different doesn't look good obviously it's blown way out and instead of just manually jumping and having to look all over the place we're just going to go ahead um the first clip So we'll see second clip, the X position is already zero in both and then we'll just take

[05:41] the Y position and post that and now you can see it's exactly the same. Now a pretty big thing that a lot of creators do that's becoming more popular is captions. If you have to do them manually, I mean there's really no good way to do that, just take a

[05:56] font and type out what you're saying. Oh there's so many editing softwares. I believe CapCut has this, Wondershare has this, is AAI captioning, which is pretty accurate, at least on Wondershare. If not, there might be a third-party website or something you could use.

[06:09] I recommend just looking for a site like that because, honestly, the amount of time you'll save from having to type them yourself, especially on longer content, is going to be well worth it. So I just hit generate, and it grabs the entire thing and generates captions for it.

[06:25] So we'll just wait for that. Okay, now you can see it's generated my captions here in this text box. So what I do then is I just scroll until the first thing with captions come up, so

[06:41] Here it is and then I just Look for double click on that and it pulls up this thing here. So and then I just make sure it lines up

[06:53] So For this it's a little cut off, again you won't be able to hear this but it's a little cut off. So I really start talking around the 4 second mark. And also it just says good but I say oh good so I'm going to go ahead and change that.

[07:08] Oh good. Um and then stretch that out so that it fills the actual time slot.

[07:20] And then sometimes, I don't know if all of them do this but sometimes on Wondershare It starts the next line of text on the last thing. So just make little corrections like that. It doesn't take long and it makes your videos just seem a lot better, a lot more well put

[07:33] together like you actually care about it. And then that's it. So this one doesn't have a whole lot of captions. So I'm going to end my clip there. So I'm actually going to go ahead and just cut all this.

[07:46] This is a little long Punch lines over And then to style your your we gonna go back to the screen to style your captions um on Wondershare pretty easy

[08:00] So we're going to drag it up here. I always put it right below my face there. I have a specific text I use. And then if you want to add, you can select your text up here, you change the size, bold it, whatever, how you want it to stack, anything like that.

[08:13] Then you go over to customize and we're going to go, I'm going to add an outline. right so I always do white text black outline and then oh this is a different text I normally use so that's fine and I'm just going to make my a little thick right a little thicker I always

[08:28] actually use uh this one and then just hit apply to all and it'll automatically add to all your things So I'm actually going to move this one down to there and then I'll hit apply to all again

[08:47] so that this text stacks properly. I'll just make sure it looks good, it does, save, and then boom we have a video complete

[09:00] with captions and everything and it's pretty much ready to be posted. The only thing I do is I add an outro, just advertising my Twitch and my YouTube to do that. I have it pre-made, I just grab it from here, throw it in at the back, drop it down, I always

[09:20] do negative 420 on the sound just so it's not too loud, and then it ends and immediately, boom, there we go. So that's it, and then you're gonna go ahead and export up here. Obviously if you want to save your work at any time you can file the project as

[09:37] I'll just name it beans as themselves and then to export it, just export. It's going to say match project settings. That's pretty much going to be it. I have mine saved as a as a prerequisite

[09:53] so I'll show you what that looks like or a preset rather. Oh well that doesn't matter. See I keep my bitrate at constant, 60 FPS, I do a high bitrate at 10,000 kilobits per

[10:06] second. And yeah, that's it. Then once you have all your settings right, make sure it's in the right aspect ratio and everything, hit export, it'll render the video, export it out, and then you're ready to post on YouTube or TikTok.

[10:18] I hope that was helpful to you guys, I hope maybe you got something from that. If you did, just drop a like, subscribe, and yeah, I'll see you guys in my next livestream or my next video, whatever comes first.
