11 – Blender Video Editing (Importing Images [ Overlay / Resize / Rotate ])


Hello Youtube. Mikeycal here. And this is
video number Eleven in my series on utilizing Blender as a video editor. Now in the previous
video, I showed you how to precisely maneuver the strips around the sequencer. And I introduced
you to the Box Zoom feature. Which is a great way to quickly zoom in on your strips and
do editing. Now in today’s video I want to talk about image import. And really there’s
only 2 kinds of images that we deal with in the sequencer. And that is, images that have
transparent backgrounds, and images that don’t have transparent backgrounds. So let’s get
started by importing an image that does not have a transparent background. Let’s go down
to the add menu and select image. And, we’re going to select this jpg file. And, you’ll
notice that it has a white background. And that it imported the strip to the location
of the green line. And that the strip is a really tiny sliver. So this is a perfect opportunity
for us to use that box zoom feature. Let’s hold our SHIFT button and hit B. That gives
us the crosshair. Now we can use our left mouse button an drag the box over the area
we want to zoom. And there you go. Now let’s right click on the right handle of the strip.
And hit the G button, and pull it to the right and zoom out to our full view. And you’ll
notice that the right handle is still selected. So we can just hit our G button again. And
pull it over the desired number of frames. Now you’ll notice: it’s covering all the frames.
Now what did you notice about this image after we imported? Well, it filled the entire frame.
And it shouldn’t do that… This is actually a much smaller image than the 1280 x 720 resolution
that we have here. But, this is what blender does with all image and video imports. It
just spans them to the full size. So let’s fix that, very simply, by right clicking on
our image strip, and going to the properties. And you’ll notice there’s a feature or a check
box here called, Image Offset. What what happens when I select this… It brings it to the
correct proportion size. So, now we just need to move it to the part of the window that
we want this to be displayed. So we can do that by using these X and Y coordinate boxes.
You can click on the X Box with you left mouse button and drag to the right. And you can
click on the Y Box button and drag to the right. And that brings it up to our right
corner. Now, where’s the movie in the background? Why isn’t it showing that? Well it turns out
that blender needs to be told that this image is an overlay. So, there is a feature, in
the properties, at the top. It’s the Blend feature. We need to switch this blend setting
to “over drop” – and there you go. Now you can see. It’s covering all these frames. Now,
that’s what it looks like if you use a non-transparent image. Let me skip ahead. I’m going to place
a transparent image in the same location and we’ll talk about that from this point on.
So I’ll be right back in a second. Ok, I just went through that identical process of importing
an image except for, I imported an image with a transparent background this time. And I
wanted to stop a this place right here to show you guys that you need to use the blend
setting of “Alpha Over” for images that have transparent backgrounds. And this will just
force blender to recognize the alpha, transparent channel of the image. So there you go. And
you can see that transparent backgrounds work very nicely when you use them as overlays.
They’re cleaner. They give you a more organic shape. Instead of having that blocky, rectangular
image. So you guys may be wonder, right now, how do change the size of this image? Well
that’s going to require that we use a transform layer. So the way that we do that is we select
our image strip. And we go down to the ADD menu. And select “Effect Strip” and “Transform.”
And whenever we create a transform layer, or transform strip, we need to remember to
hide the original strip. And we right click on that and go to the strip menu. And we go
to mute strips. This will prevent the original strip from interfering with the new transform
strip. So now let’s click on our transform strip. And you’ll notice that it doesn’t respect
the transparency again. We need to go back over to the Blend setting, for the transform
strip, and we need to select “Alpha Over.” And there you go. Now, when we scroll down
here, You’ll notice that you still have your positioning, X and Y coordinates. So you can
just drag these. But, you also have scale and rotation now. So I would recommend that
you keep the actual proportions of the image by hitting the uniform scale button. And we
can now just drag this left and right and that will shrink and grow. And you can also
go down to this rotation setting, and you can spin it around. Pretty Cool… Now we
can see that… that actually covers all these frames. I think that should do it for what
I want to talk about today. That’s the simplest way to import the images, change their size,
and rotate them. See you guys in the next video.
