- [Narrator] When you're preparing to output a rendered file
it's very important to know about the aspect ratio
as well as the final rendered size.
Now, if you click on the render or output tool bar up here,
click on render, right up here you can see the resolution
of this image.
Now if you change one of these things,
notice the other one automatically changes.
So if I change this to four or 500,
notice the other number changes.
If I change this to 1920, I'd prefer if this was 1080.
Now because the resolution is locked together based upon
the aspect ratio, if I want to make a change here
I actually need to get out of the output tool bar
and come over here to the camera itself.
So if you click on any one of these cameras,
they all have what's called an aspect ratio,
and that is right here, aspect ratio,
and you can click on this little drop down
and you can see what common aspect ratios are.
So if I'm looking for the 1920 by 1080 size,
I want to come down here to a 16 by nine aspect ratio,
and then go ahead and click on OK.
Then when I come up here to render,
notice up here 1920 by 1080,
so I'm getting the size that I'm looking for.
So that's what you'd consider maybe HD screen resolution,
and you generally want to stick to one of those standard sizes
cause that's what's going to fit
most computer monitors these days.
Or, if you're rendering for something else,
maybe you want a square rendering,
make sure you set it up in the camera first,
and then when you come over here to actually
do the output render, then you can adjust the size of it.
So it's always going to be in that same aspect ratio,
but you then have the ability to adjust how big
or how small you want to make that final render.
Those are the basics for aspect ratio and final render size.
They are linked together.
If you want to make a change to the aspect ratio,
make sure you jump in and change the camera itself.
If you want to change the size of the image you can do that
in the output tools, but make sure you do that prior
to starting your render because you can be wasting a lot
of time if you obviously make it the wrong size resolution
that you need for your final project.
