Compression with Adobe Media Encoder
Let's start first with Adobe Media Encoder. The first place to go when you're optimizing files with Adobe Media Encoder is to go up to preferences. And there are several preference settings that can make your life go a lot faster. And they start with the general tab right here. Here's the setting. So much to pay attention to make sure that parallel and coding is enabled. Not all Codex support having multiple processes compress at the same time. H 0.2 64 is notorious for its inability to support parallel processing hardware. Acceleration is much more efficient way of compressing for H 640.2 64 but formats like pro rez do support parallel encoding. This does no harm and can definitely make things faster when it's turned on. Another option is up here. Show Q. Elapsed and coding time. What this is allows you to do is you can see as you are encoding how long that particular file has been. Encoding. This is a display function doesn't necessarily change or optimize the software, but it does a...
lly to see what's going on, and I want to show you a hidden way that you can find out what's going on with files by accessing the adobe media encoder log and we'll talk about that in just a minute. One that I find really, really useful. Is this one down here? I always check. Specify output file destination. I never have to worry, but where my compressed files are located. So on my second drive here, I've got a Thunderball drive connected. I'm going to create a folder called Compressed Files. I create that folder, and I use this folder for both Adobe Media Encoder and for handbrake and for EMP, Extreme Clip and for episode, and for squeeze and compressor. Anything else? I always go to the same folder that way. I know that if the file has been compressed, it's going to live inside that folder. If it isn't in that folder, I didn't compress it, and I need to compress it, so I always set the output file destination. That means that when I bring a new file into median coder, the destination is already set, and I don't have to worry about it. Video rendering. You always want to make sure that you have GPU acceleration turned on because it will make things faster so the three speed ups that you've got here are parallel encoding setting the output destinations. You never have to worry about where your file goes and make sure that the Mercury playback engine is set to GPU acceleration, then go to memory. When you're working with memory, you wanna make sure that you give as much ram as possible. Tear Adobe applications. I assigned three gigabytes for everything else and whatever I have available. This is a laptop, and I've got 16 gigs on it. So I want to assign gigs of RAM to all the adobe applications when Adobe applications they're not running. This includes aftereffects and Premier Prelude, Adobe Media Encoder, Photoshop and Speed. Great. When those one of those applications is not running, the RAM is released and it's available for other applications. But when they are running, it's pulling most of the system. Resource is away from other applications and giving it a median coder. The more ram that Dobie has, the faster it runs and assigning two or three gigabytes to everything else, which is what I've done here does not prevent you from doing email or Web browsing. Those don't take a lot of ram it all but media encoder can use this much. Ramez. You can give it so those are how I configure preferences now with settings. It's a couple things that we want to take a look at. I'm going to create a new set of settings I'm gonna clean, create the plus key. I want to just give this a name. New setting. I'm nothing if not obvious. And we're gonna base this. H 0.2 64 h 0.2 64 is the preferred Kodak for the Web. It's good for YouTube and Vimeo and Facebook and downloadable files. It is the lingua franca of Codex today it does everything you wanted to do. The one that's gonna take its place is called H 10.2 65. We're gonna be seeing that transition occur over the next year. But when in doubt for the Web h 0.2 64 this stuff is all set. Just a couple things to pay attention to hear on the video. Kodak, uh, let's keep going down. There we go. High profile is appropriate. It works for IOS devices as well as other devices set this toe level the default high profile, four to which is the default setting perfectly OK, render at maximum depth. What this means is it if you are working with a source file, which is a bit, or you're working with a raw file, which is a 12 bit, which I can't imagine to want to compress. But if you did, if your video is a 10 bit turning this on will improve how Grady INTs air treated h 0.2 64 is an eight bit Kodak 256 shades of gray, inches, six shades of each color. That's the way it is. But we can start with a higher grade format like progress, which is 10 bit render at a maximum depth, which decreases some striping on radiance intense to increase color quality. But it's gonna make things go a lot slower. If you're working with a bid video, you haven't done color grating. You're not doing a lot of effects. You don't need to check this If you're absolutely interested in speed, don't check this cause this is gonna significantly slow stuff down. This is where you set the difference between CBR, which is only used for live events. This stream is done with a CBR setting VI Br one pass and VI br to pass when you're bit rates as they are here are set to 10 megabits per second, which is 10,000 killer bits per second. You don't need to pass to pass is going to slow things down. This is the biggest control that you've got over speed is whether it's doing one pass or to pass. When you're compressing at 10 12 16 megabits a second, you are not going to see a quality difference between one pass and to pass, and you will see a substantial difference in compression speed. Phoebe are two passes at least twice as long as one pass. Advanced settings. You can leave this off if you have just unordinary type movie. Whenever a scene changes, it'll drop in what's called on high frame. Ah, complete frame of your image. If you've got a lot of movement, it's a handheld shot. It's a dance recital. You can turn this on, and I recommend turning it on and setting it 10 90. You will slightly increase this file size but will increase quality if you just have a talking head, you're not gonna notice. It's just leave this set unchecked. Maximum render quality if you're checking where to go appear. If you're checking maximum bit depth, you want to use maximum render quality again. If you're working with a 10 bit source, you'll want to check this on and check this on, and you've automatically made your compression time three times longer. If your goal is to get stuff on the Web like now, think news or celebrity sightings or whatever you want. To be sure neither of these is checked. If you're creating something which is going to to be released and sold commercially, an image quality is much more important than speed. Turning both those settings on will improve image quality for color grating, provided you're working with a 10 bit master progress. If you're working within a pit master, you're probably not going to notice a difference. This use previews only effects. Premier. When use previews is checked and you've rendered files inside premiere. It'll use those premier render files and decrease amount of rendering time. That has to do. I tend to always want to create new render files and not work with what? I'm working within the application. But if you are in a hurry and you're using Premier and the setting of the premier project sequence matches the source format, then turning Hassan will save time. Use. Frame blending is only necessary for slow motion. Leave this off unless you're doing a lot of slow motion effects. Most the time. Most of the time, I'm going to leave all four of these off for maximum speed. Turn just these two on when I'm dealing with really high quality source files. And if I need to save time and I've rendered in premier turn, use previews on leave the other three off. One other note. While we're here. Audio format Setting A A C is always the correct format for for an h 0.2 64 setting, you don't need a sample rate of 48 K It's too big file sizes too big. Set it to 44 1 Leave it the stereo. But if you're with A A C and your 2 44 1 setting, the bit rate does not need to be 3 20 that oh, this is does not need to be 3 20 It needs to be 128. So for a downloadable file, 100 and 28 for a YouTube file. 3 20 Because remember YouTube video Facebook always re compress your file says stereo 44 1 and a bit rate of 128 k bits per second. The rest of settings can really be left alone as they're not going to affect. Um, Speed. I mean, clearly, if you're adding effects, it'll slow stuff down on def. You're working with Premier. It is easier to add overlays inside Premiere that it is inside Adobe media encoder. But the key determiner of speed The key is setting this from the default of to Pasto one pass and keep your data rates side. By the way, if you are compressing for the web, a download Hang on a second change one setting. Now I want that to be four to, And if you are compressing for the web and not YouTube, then you want to set this probably two to pass and you're gonna want to change this. And this is gonna vary if I'm on a 7 20 image. I'm going to set this to for the target and 2.2 for the maximum. If I'm on a 10 80 image, I'm gonna set this to 3.5 and set this to four. Those are my starting points for 7 22 And for 10. 83.5 and four. If I'm doing a talking head as I'm doing today, I can use much. Lower data rates are webinars a compressed about 1.7 megabits a second, sometimes even lower than that, but most the time for 7 20 Image compressing a two megabit level 2000 K bits per second and a 10 80 image at 3.5 K bits a second should give you good quality. Always go to to pass. But, um, with hardware, acceleration to pass may not yield. The results that you're expecting won't be bad, but it may not be worth the time to do a test for yourself. See if one pass looks good. If it looks good, it is good. There's no underlying I can't see it, but it's lurking in the background, going to do damage. No, If the image looks good, then one passes fine. And if it doesn't go to to pass
