and what we're about to do is actually fairly simple it's about changing the resolution and/or scaling a video frame or an image frame using OpenCV and python now the reason you'd want to do this or the reason you do this in general has to do with a couple things one of them is perhaps you just need a smaller video size or a smaller image size so you want to rescale it because of that reason another one is when you're processing a lot of data or a lot of images or a lot of video a lot of times you might need to scale down a image or frame because of that as well so this is simply a reference for you to be able to go back to and update your projects to make sure that you're using OpenCV as efficiently as possible and you're just not overloading whatever computer you're working on now this becomes even more important when you're using something like Raspberry Pi for like a security camera and even if you have like a 1080p web camera attached to it sometimes you might need to shoot in 480p instead of 1080p for that reason to make sure that it's a low file size as well as that it's not overloading your Raspberry Pi whichever one you're in abusing so what we're gonna do is we're gonna jump into this blog post the link that you see right now is what we're gonna be using and we're just gonna be going step by step using a very basic thing to make this happen now we're into my starter code this is code that came from you know a previous tutorial we did but as you see it's actually fairly straightforward and fairly simple this is something you'll probably get very used to either writing or copying and pasting because you use it a lot and now what I'm gonna do is I'm gonna go ahead and start to bring over my code from the rescaling so going back into that blog post I'm gonna just copy and paste some stuff so we can see just generally what's happening here and just go line by line for all of that so above the while I'm just gonna paste in those new methods for make it somewhat of one of these scales now what you might end up doing is just this changed resolution and what we see here is these numbers three and four cap as in this capture this video capture item so if you actually change the name of that you would want to make sure that these names are changed as well but basically what's happening here is there's parameters that you can set that are built into OpenCV and I'm just changing those parameters three is for the width and fours for the height and that's how we get 1920 by 1080 or otherwise 1080p and that's true all the...
