 Okay, today we're going to start getting into some of the more fun stuff. I almost said funner and then people give me a hard time when I say that. Some more fun stuff with video editing from our shell using Melt and MLT. And we're going to start working with filters, which are kind of effects and just editing the look of the video and or audio in some cases, but we're going to look mainly at video today. So real quick, let's say real quick, I'll show you that I've got my videos in here. The MOVs are the convert videos from my camera. And there are a bunch of filters that MLT offers. So I'm going to say MLT dash query and then I'm going to say filters and it will list all the filters that are available, audio ones, video ones. So let's say we want to make our video black and white or actually gray scale. It looks like they have gray scale in here. I don't know if there's a difference. I've been using this one. They may just put it in there because gray can be spelt two different ways depending on what country you live in or how you feel that day. So there is our gray scale filter. Let's go ahead and throw that in there. We're going to say MLT, then name of one of our, well, we'll just say all our videos. We'll just play them all. So all dot MOV, in my case, your files might have a different extension, remember is case sensitive. Then I'm going to say filter and gray scale. Go ahead and hit enter. And it will preview all our videos here now instead of color. They are in a gray scale. Also sometimes when I do gray scale stuff, one of the things I like to do with videos is vignettes. So let's have a look at vignette and we'll look at some more options for it. So let's actually go back and instead of gray scale, we'll just add a vignette for now. So I'll say filter vignette, which is just kind of a black border around your video. By default, the default settings, it's kind of harsh. It's a very sharp circle here, a little too dark. I like it a little more blended in. So let's look at our options for that filter. So what we can do instead of just running it, what we're going to do is we're going to say dash query, just like we queried filters before. But instead of querying all filters, we're going to query the vignette filter. So we can get rid of the MOV here. So melt query filter equals vignette. And it will show us all the options for the vignette. You can see these little dash marks. These are new settings, and then there's the parameters for those settings. So we have our identifier here, smooth title. It's feathering. And then you get some options here, mainly want to look at the minimum and maximum, which in theory you would think that the minimum would be the lowest you can go and the maximum is the highest. Turns out that's not true. So I don't know if that's just a typo in here or not. But with the vignette, you can go higher than 1, and I actually like it around 4 or 5. But most of the settings, it seems, in MLT are settings from 0 to 1. So I am going to change the smoothness of that vignette. Eventually. Actually, let's play with radius first, because you'll see that a little bit clearer, I think. So once again, I'll play all my videos. So we're going to run Melt, all my MOV files using the filter of vignette. And this is what it looks like by default. You can see the black border around the video here. Run that same thing. But this time I'm going to say radius equals, oh, and by the way, if we scroll back up here, it also tells you the default. So if you don't type in anything, radius by default is 0.5. So let me set that instead of 0.5, I'll set it to 0.2, and you'll see a much smaller circle. Also you can go higher. Instead of 0.5, I can go 1, and that is so big it isn't even on the video anymore. Instead of 0.5, we can do 0.55, and it will be slightly bigger than the initial one. So you can get just a little bit around the edges here. So you may like that, like that. I personally like changing the smooth for vignette. And as I said earlier, I like setting it to like 4 or 5. I like a very faded, also it also depends on the video. So you can see it's actually blending all the way down to, you can see a little bit clear on the white wall there, but it was coming down to here. So it definitely makes the video darker. You may not want that look. All depends on what you're going for. You're just an art teaching you the techniques. It's up to you to come up with the artistic view of that. So that's a vignette effect. So now we can take that, and we can also add another filter of gray scale. So now we have the vignette with a gray scale. With vignettes, or with gray scales, sometimes I like to add a filter of grain, and it makes the video grainy. And that's great if you're going to use an old film effect. So filter, old film, which has lots of options in it, but we're just going to go with the defaults, which kind of adds a flicker to the video. There's also options for scratch lines, and how if the video jerks up and down. So we kind of made an old film. If you've watched my tutorials on Caden Line in the past, I actually like using this incorporation with an overlay to get a more realistic effect. But just going with the basic filters here, we're creating a video here. You'll also notice, well you may or may not notice, it's jerkier. I'm screen recording here, I'm recording at like 15 frames a second, so pretty much all the videos I'm showing you are probably a little jerky. But that's because we're doing a preview here. It's showing at real time, so it's dropping frames. If we were to save this to an output video, it won't play this jerky. I mean, unless we're doing a film, we might set the frame rate lower to get that feel. But let's go ahead and run that same command. So we're using melt. All our MOV files are running a filter of vignette. I'm smoothing it to four, because I like a nice smooth vignette. A filter of grayscale, filter of grain. That has settings as well, you can go in and change. Same as a filter for old film, there's a lot of settings for that. I'm just using the defaults. So I'm using all the default settings for these filters, except for the smooth for the vignette. Next, we're going to say consumer, if I could type today, consumer AV format. And then colon and the name of our file, I'll call this oldfilm1.avi. I'm going to use a video codec of xvid. So I'm going to use the library for xvid, so libxvid. And we'll give it a quality rate of 5000K. And we'll hit enter. Now with all these filters, it is going to slow down the rendering process somewhat. You can see it going here. I'll post our final render video here at the end of this video. Once again, this is, I think, part five of my tutorials on this. Be sure, I should have said at the beginning, be sure to watch the others. There should be a playlist on my YouTube channel. Hopefully, maybe I put annotations to a playlist or check the description. If not, just go to my filmsbychrist.com. My website should be a link in the description or my YouTube channel. Look at playlists. All these videos should be in a playlist together in order. I labeled something like shell video editing or video editing from the shell or with shell scripts. It will be there. I suggest watching them in order or else you'll probably be a little lost. But yeah, we're getting into fun stuff with this. And we could definitely create a video completely from the command line now using this. I added the filters to all the videos. You can add them to individual clips. So yeah, visit filmsbychrist.com, that's Chris the K, link in the description. Check out the site. Check out the help button if you need help. And also, think about donating, there's a donate button there. I hope you have a great day and here is the render of that video.
