Multi-frame rendering

“

- [Narrator] You probably heard that After Effects just got a major boost in performance with the new multi-frame rendering feature, which is turned on by default. This option will use all your computer power to accelerate rendering, and it's also supported by Media Encoder and Premier Pro when you are using all grads file that uses the After Effects render engine. So we are talking about speed improvements between 1.5 up to three times faster or even more using the same hardware you already have. Adobe worked hard to put all their built-in effects to support this. And third party developers are already shipping updates to their versions of their plugins. Now, if you are using an effect which isn't ready for multi-frame rendering, you will see a warning notification in the effect controls. Okay, so I'll delete this effect and I'll show you that under the memory and performance preferences tab, you can turn this feature off in the rare case that it doesn't work with your comp, or you just want to revert to the way After Effects used to render before this feature was introduced. So this is what I did, and then I rendered this composition that we have here just to see how much time it will take. And the result was almost two minutes. Now let's put the multi-frame rendering to the test and render the same thing this time by switching the new option on. Notice that you can also preserve a certain amount of percentage for your CPUs for other applications, if there is a need for it. Now, before I'll go ahead and render, I want to show you that there is also a new notifications preferences. So you can enable this, and you will be notified by the Creative Cloud desktop and mobile app when the render is finished. Also, there is a link to download the Creative Cloud mobile app. So I'll click okay over here. And I want to show you that at the footer of the render queue, there's also a new button which is going to do the same thing. So if I enable it, it will notify me when all the active queue renders are finished. So I'll enable it, and then I'll purge the cache. And this will allow us to compare between the new speed and the previous render. And it will also give me an opportunity to show you the new redesign render progress bar. So to see it, I'll press render. Now you can see that the blue bar is showing up. This is going to represent frames that were processed. And in front of it there is also a green bar, which shows you all the frames that are being sent to the other processors or cores on your machine, and being gathered together. You can also see a quick status by clicking on this info button and it will show you the render progress. Once the render complete, and this one took less than half of the time of the previous one, which is twice as fast. This is just amazing. You will also get a notification via the Creative Cloud desktop and mobile app. And if you have one, you will also get the same notification on your watch, and all of this with zero configuration. So this is a major thing that Adobe worked on for the last two and a half years. It's finally here together with the speculative preview that I've showed you in a previous movie. And I think it is a massive game changer for every After Effects user. But wait, there's more. Next time I'll show you how to render even faster by understanding the way After Effects process pipeline works. So stay tuned for that. And until then, take advantage of the new multi-frame rendering inside After Effects.
