For the launch of Framer’s animation API, Benjamin den Boer released a project with 30 example animations. And later, he shared 20 Framer Motion examples.
I took those animations and translated them into different versions:
- I made Framer Motion versions of the original code components,
- recreated the Framer Motion animations as code components,
- and also made an overrides version of each animation.

Here’s my remix of Benjamin’s examples: all the animations together (with a few exceptions) in those three formats.
Thanks to Framer Motion, we can now include animations in webpages. So each page contains a live example, like this one:
- Hey gang - welcome to your first Frame Motion (for React) tutorial. In this tutorial I'll explain what Framer Motion is and what you'll need to know already.
- Framer Motion doesn’t have a page component, so I couldn’t recreate the examples that use it: 14, 15, 16, and 19. And it doesn’t have a scroll component either. But a motion.div can be made draggable, so it’s easy to create a scrollable div that has the same inertia animations as Framer’s component. (Examples 17, 18, 20, and 35).
Some animations are triggered by a mouse hover, like the
whileHover
example below. These don’t work on touch devices, so when you’re on a phone or tablet, you’ll see a GIF instead of the live animation.Differences between the versions
The code component version will contain Frames, the Framer Motion version Motion Divs, and the version using overrides will work with what’s drawn on the canvas.
Code component
Here’s that first animation again, as a code component based on a
<Frame>
:In the examples on the next pages, I’ll omit the
import
s at the top. Those are often the same anyway, and you can always check out the entire code in the .tsx
file.See this issue: framer/motion#493. Copy link amcc commented Apr 24, 2020. Fixed it and the have updated the repo and sandbox site with the changes, all working now. To do this yourself add this kind of thing to your gatsby-browser.js: import. Describe the bug When AnimatePresence children unmount, the exit animation happens to completion before positionTransition animations take place. When new children mount, no such delay exists. To Reproduce Steps to reproduce the behavior: Create basic example with AnimatePresence parent and motion. children. Motion.div / motion.div /.
Framer Motion
The Framer Motion examples are included in the Framer project, as code components that use
<motion.div>
s. And there’s also a CodeSandbox version of each animation.A motion.div doesn’t have all the fancy properties of a frame, so you’ll have to set its CSS properties on
style
, like you would with any other div.But at the same time, a
motion.div
does have animate
, transition
, drag
, etc. These extra properties make the animation magic work.A
motion.div
doesn’t have a frame’s handy center
property, so most examples are wrapped in a <Center>
component. Here it is. Wirecast download. It’s just a Flexbox
<div>
that centers its content:Importing the motion library
The
motion
component is part of the Framer library, so that’s how I import it in the examples: Omniplan pro 3 1 download free.But when using motion elements on the web, you’ll have to get it from the Framer Motion library:
Page and scroll
Framer Motion doesn’t have a page component, so I couldn’t recreate the examples that use it: 14, 15, 16, and 19.
And it doesn’t have a scroll component either. But a motion.div can be made draggable, so it’s easy to create a scrollable div that has the same inertia animations as Framer’s component. (Examples 17, 18, 20, and 35)
Overrides
The overrides version will almost always be the shortest one, simply because the frame or div doesn’t need to be drawn. (It already exists on the canvas.)
Things get a bit more complicated when there’s more than one frame because you’ll then have to use a data object to communicate between different overrides. (Although sometimes a
motionValue()
suffices.)But when there are many frames, it’s often not worth it. I didn’t even try to recreate examples 35 and 36 because it would result in even more code than the Framer Motion and code component versions.
A key frame (or keyframe) in animation and filmmaking is a drawing or shot that defines the starting and ending points of any smooth transition. These are called frames because their position in time is measured in frames on a strip of film or on a digital video editing timeline. A sequence of key frames defines which movement the viewer will see, whereas the position of the key frames on the film, video, or animation defines the timing of the movement. Because only two or three key frames over the span of a second do not create the illusion of movement, the remaining frames are filled with 'inbetweens'.
Use of key frames as a means to change parameters[edit]
In software packages that support animation, especially 3D graphics, there are many parameters that can be changed for any one object. One example of such an object is a light (In 3D graphics, lights function similarly to real-world lights. They cause illumination, cast shadows, and create specular highlights). Lights have many parameters including light intensity, beam size, light color, and the texture cast by the light. Supposing that an animator wants the beam size to change smoothly from one value to another within a predefined period of time, that could be achieved by using key frames. At the start of the animation, a beam size value is set. Another value is set for the end of the animation. Thus, the software program automatically interpolates the two values, creating a smooth transition.

Video editing[edit]
In non-lineardigital videoediting, as well as in video compositing software, a key frame is a frame used to indicate the beginning or end of a change made to a parameter. For example, a key frame could be set to indicate the point at which audio will have faded up or down to a certain level.
Video compression[edit]
Framer Motion Api
In video compression, a key frame, also known as an 'intra-frame', is a frame in which a complete image is stored in the data stream. In video compression, only changes that occur from one frame to the next are stored in the data stream, in order to greatly reduce the amount of information that must be stored. This technique capitalizes on the fact that most video sources (such as a typical movie) have only small changes in the image from one frame to the next. Whenever a drastic change to the image occurs, such as when switching from one camera shot to another, or at a scene change,[1] a key frame must be created. The entire image for the frame must be output when the visual difference between the two frames is so great that representing the new image incrementally from the previous frame would require more data than recreating the whole image.
Framer Motion Vue
Because video compression only stores incremental changes between frames (except for key frames), it is not possible to fast forward or rewind to any arbitrary spot in the video stream. That is because the data for a given frame only represents how that frame was different from the preceding one. For that reason, it is beneficial to include key frames at arbitrary intervals while encoding video. Feeder 3 6 4 cylinder. For example, a key frame may be output once for each 10 seconds of video, even though the video image does not change enough visually to warrant the automatic creation of the key frame. That would allow seeking within the video stream at a minimum of 10-second intervals. The down side is that the resulting video stream will be larger in size because many key frames are added when they are not necessary for the frame's visual representation. This drawback, however, does not produce significant compression loss when the bitrate is already set at a high value for better quality (as in the DVDMPEG-2 format).
