Welcome to rendering an animation.
In this video you will learn how to render your animation how to stop the rendering.
What settings to use for good results and how to preview an animation.
Once Chet has finished rendering so let's hop straight on over in a blender.
Now some of you observant students would have realized that under the renderman you there's this button
called render animation with the short cut control in F 12.
Now where the.
Don't don't touch it don't actually cause it we're not ready to render the animation just yet.
We need to do some setting changes first.
Especially as this is our first animation.
So what to do.
Well first of all let's go over to the render properties and look through this.
So we've got a lot of options here.
First of all your device that your rendering on if you've worked out that your GP you is faster than
your s.p. you make sure it's on the GP you scrawling down a little under dimensions we have the resolution
and the percentage of final resolution.
So this is going to be 50 percent of 10 ATP essentially.
Now obviously the higher that is the more resolution there is the higher the image quality is going
to be.
However it's also going to take longer to do.
We're going to leave the frame rate as it is.
That's absolutely fine.
And if we scroll down here we have an output folder Now that is very important that tells blender where
it's going to put your information.
Now contrary to what it feels like down here when we select on what to save it has at the moment it's
PRNG and we go Oh there's lots of video options here surely we select.
That's the simple answer is No.
The reason for that is it's much better to make your animation an image format so you end up with.
In this case 120 images and then compile them into one single movie later on.
If for whatever reason you do decide to use one of these movie options and then later on during this
five hour render that you're about to do something goes wrong you have a power cut.
Anything that stops the render will kill your file completely.
However if you had finished off rendering 50 out of 120 frames and they you would have 50 pictures on
your computer.
And so if your computer crashed blender crashed you lost power or whatever reason you don't have to
worry because the next time you change this value here you change the start value to 50 or 51 and you
carry on.
So there's a great reason for not having it render straight to a video.
It also gives you more control doing it this way.
And there's an additional benefit which will go over in a couple of lectures time where you render across
multiple machines very powerful.
So the start and end frames are very important that dictates how long the rendering is going to last
for as well we just hinted at that there.
So anything beyond any animation beyond the start and end or before the start and end won't actually
make it to the final render.
Of course it's the camera settings as well that dictate what is being seen.
Now one final thing and we've touched on it when we did our render tests earlier answer we scroll all
the way down to where it says proformance.
Now you'll want to set this appropriately for your system.
So cause I'm using a s.p. you generally the smaller tiles are better and you'll meet need a much larger
tile or size.
If you're using a GP you again if you've not done the full test I do suggest you do that because now
that we're rendering an animation it's going to take several minutes to do it.
So now I've got it to 16 by 16 I'm happy with everything else.
Let's go to sampling.
I'm going to do a test render to begin with.
So on this samples here on the set the render level to just one.
Okay that's good.
Let's go up.
Let's select an output folder unhappy leaving it as the temp at the moment.
This is just an example but you can go into here and select a specific location to store your animation
on your hard drive.
Now when we come to do our final animation we'll actually pick a folder that isn't buried deep in your
system.
In fact the temp folder itself is quite hard to get to on a Mac.
A lot easier to get to on a piece.
So in this case I'm going to literally find I'm going to put it in my downloads following create a new
the new directory there and said it has one sample lamp and this is literally just to get a feel of
our animations.
So with that selected there we can go ahead and go render and render animation.
Well we can see that because we've only got one sample.
It is very quick to render out our animation itself but it's still going to take several minutes because
it's going to take at least two minutes.
So I'll let this whiz ahead and I'll join you in a moment.
Okay so we're halfway through our rendering and one of the things that I've noticed after watching this
is because there's no reference material in the background I'm not sure whether we know by looking at
this whether the lamp is actually jumping at all.
But let's let's let's that be gone.
I'm just going to stop the rendering at the moment.
There's a little cross here that will stop the rendering on the info head a bar and we can click that
that and it just stops in place.
Now if we go in to our.
Operating System.
And I'm just going to find these sample lamp folder.
Bring this down for you and we can see oh has one PRNG we can actually go through.
These are the means to open that.
And I'm down to 78 so at any point I can just continue from 78 onwards.
If I wanted to continue this particular render.
So in a render menu itself I can go to play rendered animation and it'll play.
We got to.
And then it will stop and repeat.
Now we can see here there is a reference there's just this thin band at the back.
So perhaps in this case I'm not going to add anything to our scene at the moment but it just tells you
here even on this very rough and very grainy rendering that there is something probably missing to give
the viewer the person watching this video a clue even though there is a dark band there now I don't
know with more samples whether that's going to be more prominent is certain the obvious that it's jumping
as soon as we swing round and see it landing again but I'm not sure if it is at the moment anyway so
that's all of our stuff done.
We've got a series of pictures I'm just going to continue rendering this out.
Where do we get to we got to.
You got to number seventy eight so if you need to stop for whatever reason the great thing is here I
can continue and I'm just going to check 78.
It's a whole picture.
That's great.
So I'm going to finish off the rest of my rendering by going down to here and typing in seventy eight.
Now once I've typed in 78 I can just go back to render and render animation.
And off it goes and completes the rendering.
Excellence of the renders just finished so we can hop back onto render play the rendered animation.
See how that's come out.
Of course it's just going to play the last bit of our animation.
Which looks absolutely fine.
Brilliant.
So we have a quick look after doing that rendering.
We see that there are a hundred twenty one items in here there's unjoin 21 Pictures.
And as we can see if we scroll down they are of our lamp jumping.
Excellent so we've got all of our 121 frames already down.
And that means for you guys it's a challenge time.
I would like you to render a trial animation so set up a one sample test folder to save to set to render
samples to one and render your animation preview your animation and make sure you were happy with it.
Paul's video now and give that a go.
Welcome back.
How did you guys get on.
Did you have to go back and make some adjustments.
Are you happy with that render with that trial render.
If you're not if the cameras in the wrong position if your model looks a bit odd if you want to move
something do something else.
Now's the time to go back and make those alterations before we go ahead and random the full animation
which may take several hours to do.
Right so I might as well take this opportunity to go back to the 3-d view because one of my concerns
was that with the background being so smooth we might not actually be able to really grasp that this
lamp is jumping up in the air.
So I'm happy with the end and the start location.
But this I'm not happy with because it doesn't really convey that the lamp is actually going upwards.
I could put something in the background that might help for reference.
But in this case I can also help by just adjusting the camera.
So let's pull it back down to the ground plane and zoom out slightly and we can zoom out but just move
it all that's rotation not location.
There you go.
And let's pull that across a little perhaps up still in frameless to see how that looks now.
So let's play that animation.
We're not at zero so that set it back to zero 6 jumping up.
Right.
That peaks just above the frame.
I do want to keep it inside the frame so let's just stop that from playing with the right key combinations
that jumps up a little bit there.
So if we raise that up which is said ever so slightly.
So that's wonderful there and here and perhaps I will make this just a little bit more dynamic by starting
slightly behind our lamps our start here but this time rotate it round.
So I'm starting like this.
In fact the lamp.
It's still going off there.
So we're going to have to pull it this way just a little bit more.
Right.
Let's try that.
In fact let's.
Go down a little and just push it in a bit closer to the camera.
Does that go off the camera.
No that's fine jumps up stays in frame.
That gives a much better impression of height.
A case of made the changes that I like.
I'm going to create a new folder.
So let's go up a directory and this store of this in my down notes for temporary use.
And I call it one sample test too.
Lamp.
You can call it whatever you like.
And I'm going to accept that as the location and I'm going to hit renderer animation and I'm going to
go make myself a cup of tea whilst that renders out.
Okay so the renders all done brilliant.
And I've got a lovely cup of oh great.
How did you guys get on.
Please keep your renders your test renders that you've currently got because not in the next lecture.
But the one after that you'll be able to export this to a movie to share with everybody.
Brilliant.
See you in the next lecture.
