Compression with Apple Compressor
Let's take a look now at compressor. This is compressor notice here under video sharing services. Everything, whether it's Facebook, YouTube video are these six settings which are all in video sharing services. If you want your finished file to be 7 20 p, you start with a 7 20 p setting. You want to be 10. 80. Start with the 10 87 you wanted to be four. K Start with a four k setting, but let's get real here. Very, very few people can actually watch a four K file. Even fewer people have the bandwidth to support downloading a four k file. This is essentially just marketing hype. At the moment, you're welcome to create for que files, But keep in mind that when you do, most people are gonna be looking at it at 7 20 image size. You're gonna have all this stuff up there, and people are gonna be able to watch all the quality for me, everything that I post to 7 20 If I were doing dramatic work, I would post a 10 80. But I wouldn't worry about posting a two K or four K, at least not yet. The mo...
nitors aren't big enough, and the band with isn't there to support it, especially worldwide. So let's take a look at how we can optimize compressor and as before, it's going to start by creating a new location. So I'm gonna click on locations and let's click the plus Key Goto our second drive, and there's are compressed files folder and click Choose. This means that if a file has been compressed, it's going to show up on my second drive, and it's gonna be in that compressed Files folder, which means that the file is there. I've compressed it. If the file is not there, I haven't compressed it. Then we'll make that a default setting by going up to compressor preference is much simpler than the preferences inside Adobe Media Encoder. Under General, change the location to point to that custom compressed files location. This means that any file that I bring in when it gets ready to be compressed, it's always gonna be stored to the same folder. This makes my life so much easier because they can always count on where a file is going to be stored once it's compressed. So let's just add a clip here and we will go back to settings and let's take a look at how weaken optimize this setting so we'll go YouTube. One pass will just select that highlight of setting open the inspector. Make this goal a bit bigger. I've got the compression setting highlighted on the general page. There's no riel changes. This is all just fine. We can leave that alone. Let's go toe audio. Exactly the same rules apply in compressor as in Adobe Media Encoder. If you've got a stereo file, it does not need to have a sample rate greater than 44 1 Both of those sample rates 44 48 exceed human hearing 44 1 means your file size is roughly 10% smaller. You always want to compress this A A C and again stereo 44 1 should be 1 28 or higher for YouTube, for instance, with YouTube I, which is double it to 2 56 That gives you to plenty of audio data to throw it away when it's compressing your your project. If it's a narrator, one person talking, then I would change this tamano. I would change this to 22 which is still exceeding the frequency range of human speech and notice how it automatically changes the bit rate. Or you could raise the bit rate just a little bit. But notice how we're able to save a ton of space first by deleting one channel and then by changing the sample rate from 44 12 22 05 up. So that's audio. The real speed options, though, are in the video setting automatic matches your frame size and aspect ratio and frame rate and field order. Those tend to be most the time. Correct. A change with the 4.2 version of compressor. The H 0.2 64 profile should be set the high that works for all IOS devices. C B A. C, which you just nod your head wisely and say Wow, cool. C B. A. C yields higher image quality than C V l c. I mean, we all knew that, for heaven's sakes, but set that to C B. A C key frame interval. Leave that toe automatic again. If you have lots of movement handheld shot, change it to like and you should be fine data rate. We want to set a custom data rape and again if we're dealing with the video, which is going to be downloaded for the Web and at 7 20 started 2000. If it's, um, 10. 80 started 3500 and this is where you enable one pass or to pass. When you're doing single pass, it's going to be mawr than twice a Sfax as when you're doing to pass if you're going to YouTube. Vimeo, Facebook. Always always, always use single past. So if we go here, this is our YouTube setting to generate a 7 20 p image. When I go to video and scroll down noticed that the data rate is set to 9765 kilobytes per second. It's got a high profile C B, A C entry promoted. These numbers are fine, but you don't want to do multi pass. You don't need to do multi pass. When the data rate is that high, we're going to change it. So when I change it, let's just do this here. Go down to YouTube to change it. You click on the change, but next a quick time and see this choice down here says Faster encode or better quality. When your data rate is 10-K or higher, you're not going to notice a difference between multi pass and single pass. You're not interested in the smallest file size because YouTube is going to re compress it. So set this dialogue to single pass. How did we get there? We went too quick Time settings change and changed it from multi pass, which is the default to single pass. This is also where you can dial in key frames. Key frame is not what we know of in terms of setting an animation parameter key frame is quite records an entire frame as a self contained picture called an intra frame or an eye frame. And here, automatic. It's fine for YouTube. Just leave it automatic for a downloadable video. Change it to every set it to 90 and that will be a good choice again. This is where you set your data rate. YouTube 9007 is perfectly fine video perfectly fine for I, um, downloadable video set it to for 7 20 Yemen shirt 3500 for ah, a 10 80 image. By the way, down here under quality. This is only happening when you're re sizing. The one mistake you don't want to make is don't set resize to best. Don't set re timing to best because when both of those air set the best compression time is measured in weeks, not ours. Leave the defaults. I think basically the defaults are going to be fine. I used to do Ah, a long speech about when better is better than best. But in point of fact, better is better than best because when you use best, it isn't better than better because best to slower than better. Better is better than best, which I know all of you remember anyway. So those are the settings for compressor, except for one. And that's this one. When you go up to preferences and we click on Advanced, this is where you're able to enable additional compressor instances. This should be turned off for I. Max turned off for Mac book pros and turned on for Mac pros. You then go to this pop up menu, and it will show any number from one to probably five, depending upon what computer you've got. High Macs and Mac book pros will show an instance of one. Everything slows down dramatically for Mac pros. This will show a number from 3 to 5. Pick whatever is the largest number because that's going to give you the best results. So if you have a Mac Pro turned this on, set this as high as possible. If you don't have a macro, if you work in the Mac book pro or an I Mac, turn this off this second option that used the GPU to process final cut content. Always leave that on because it enables the GPU when you're using send a compressor coming out of final cut. It enables the cheap EU dispute up the compression of the video.
