Render Animations FASTER Using AI - Zweisprachige Untertitel
When it comes to animations, render or render codes are the biggest obstacles.
You could potentially use the real-time software, but the quality is not there yet.
In this video,
I will show you how to drastically cut the render times, and as a cut the codes if you are using a render farm.
My animation is composed at 25 frames per second.
This means that in order to get one second of animation, I have to render 25 still images.
My full animation excluding video footage is 1 minute, 1 second and 70 frames long.
It means that I had to render 1,542 images in 4K resolution.
What if I tell you that we don't have to render all these frames and or render them in a lower
resolution and still get high quality results?
This is exactly what I want to tell you.
We can use Topaz Video AI software to achieve that.
Topaz is a software that can do upscaling and frame interpolation of videos.
With upscaling, you are able to, for example, render full HD footage and upscale it to 4K.
If we render full HD instead of 4K, we speed up rendering 4 times.
Frame interpolation is used to create slow-motion video from footage recorded in lower framerights.
For example,
if we have 25 frames per second footage and we want to slow it 4 times,
the result will be very laggy because we don't have enough frames.
With top us, we can generate this missing frames and achieve a smooth and natural result.
We can use the same logic to speed up our render.
Now we are able to render every second, fourth, eighth, or even 16th frame and generate the missing frames using this software.
Here is the math.
Let's assume you are using a render farm and we'll use 4 times interpolation on average across the project plus 2 times upscary.
Your build will be just 1 16th or 6.25%
of what it would be if you render all the frames in the final resolution.
Now, let me show you how to upscale your animation.
Upscaling is really easy.
First, let's load your sequence.
We have to change the type here to see the still images.
Then you just go to the output resolution and choose two times upscale.
Keep the frame rate the same, as you set it in 3ds Max.
I prefer to do upscaling and frame interpolation separately to avoid issues, but you can try to do it together.
Here is the result of this particular example.
You can see that there are no issues, and the image looks like it was rendered in 4K.
Here is the something version, so you can see it better.
I think we can push it even further and do 3 times upscaling.
I think it looks pretty good.
Here is the comparison between 2 and 3 times upscaling.
The 2 times upscaling looks better, but the difference is not huge.
Frame interpolation is easy as well.
After load your sequence, you just enable it here.
I like to change the AI model to chronos and keep the rest of the settings as default.
The only thing we need to change is the slow motion.
Here are a few examples.
You see that interpolating every second frame looks fine, but if we move to four and eight frames, we have really no disabled problems.
You have to treat each situation individually and do some test renders before to see how far you can optimize each scene.
For example, here we rendered every 16 frame without issues because the camera movement is slow and there is no movement in the scene.
But there are so we cannot use frame interpolation, like here, for instance.
Where something is moving fast, it can be a camera object or lighting in this case.
Topaz doesn't have enough information to accurately interpolate a frame.
In this case, there should be a hard shadow line in between, but the software decided to do a soft blend.
In this case, you either have to render every frame or do a frame interpolation and re-render only the problematic frames.
You have to decide what's more beneficial based on your particular example.
Similarly, here we couldn't do frame interpolation because of the bubbles,
but we figured out the smart solution to render the whole image every eighth frame and re-render every frame of a small region.
where the bubbles are, which we place on top.
It drastically decreased the render time, as this shot was quite demanding because of a shallow depth of field and caustics.
It's all about being smart and flexible.
If you want to improve as an artist's secure job and be perceived as an expert in the field,
boosting your skills is the best option.
With more than 80% the lessons from our new animation training, you will learn everything you need to know about commercial architectural animations.
We structured the course in 10 modules to support you with the most effective learning.
We explained how we created the animations step by step, so you will be able to create your video afterward.
Check all the details on our website.
When it comes to rendering costs, let me break that down for you.
We used how you cloud rendering.
On average,
the rendering time of one frame in 4K resolution on my PC was about 40 minutes, as high quality was my number one priority.
Let's put the number of frames and the loading time.
Here is the estimated cost, 10 units is $1.
So in this case, it would have been around $5,500.
Now let's plug in the values we can achieve with the help of topas software.
I will put one fourth of the time it would take to render a 4k image and I will make
the number a bit higher because it's not linear.
Some calculations are regardless of resolution.
I will divide the number of frames by four, assuming red the ring every fourth frame on average.
And here are the results.
The is huge, as in this case, the whole rendering would cost only $450 compared to $5,300 with standard rendering.
Lastly, let's cover the scenario with 3 times upscaling.
This time, we have to divide 40 minutes by 9.
I will add a of time here as well.
Now the bill went down to only $184.
For the students of our new animation training,
Helio gave $200 in render units so you will be able to render your first animation for free if you use the methods from this tutorial.
Next, let me show you how to set it up in 3ds Max.
Let's say your animation ranges from frame 1 to frame 66 and you want to render
every You cannot do that this way because stopas will not be able to create frame number 66 with only the previous frame.
The software needs two frames to create a new frame in between.
So in this case, we have to render frame 1 to frame 67.
And later, we'll cut this last frame.
Make sure that, for example, your camera is animated beyond frame 66 in this case.
If you want to render every 8 frames, we have to render all the way to frame 73 for the same frame.
Here are the render images.
We rendered every second frame, so we have frame 1, 3, 5, and so on.
The problem is that Topos software or any other video editing software will not read this as a sequence.
We can do it quickly with the power rename tool, which is a part of power-choice-free software.
Just select all the files, right-click, and choose the power rename.
In the top field, we type the part we want to change, as an example I will change the exterior part.
In the bottom field, we type the new name.
And here it is.
The second problem is that we have different numbers in each file name.
So in this case, we have to change the last four characters.
Type this expression.
In the bottom field, we need to use an expression as well.
This is the one we need.
The number in the expression specifies the total number of digits in the name.
If you use 4, the name will have the same format as before.
Make sure your regular expressions option is checked.
Click apply.
You can see that we have 4 digits in every name, and all the numbers have plus 1 increments.
Next, let me show you how to export front-top us.
After you set it all up, open the Export tab.
Here, you can choose if you want to export it as a video or image sequence.
I prefer to export it as EXR to keep the highest quality for future color correction and final export, but it can get quite heavy.
I would like to keep the original name, but I prefer not to keep the original frame numbers.
I will set it so it starts from frame number 1.
When you adjust your settings, just click Export.
You can save your own presets as well.
