<Sequence>
By using a sequence, you can time-shift the display of your components or parts of your animation in the video.
tsx
constMyTrailer = () => {return (<><Sequence from ={0}durationInFrames ={10}><Intro /></Sequence ><Sequence from ={10}><Clip /></Sequence ><Sequence from ={20}><Outro /></Sequence ></>);};
tsx
constMyTrailer = () => {return (<><Sequence from ={0}durationInFrames ={10}><Intro /></Sequence ><Sequence from ={10}><Clip /></Sequence ><Sequence from ={20}><Outro /></Sequence ></>);};
All child components inside a <Sequence>
will have their value of useCurrentFrame()
shifted by the from
value.
Using the durationInFrames
prop, you can define for how long the children of a <Sequence>
should be mounted.
By default, the children of a <Sequence>
are wrapped in an <AbsoluteFill>
component. If you don't want this behavior, add layout="none"
as a prop.
Props
The Sequence component is a high order component and accepts, besides children, the following props:
from
required
At which frame it's children should assume the video starts. When the sequence is at frame
, it's children are at frame 0
.
durationInFrames
optional
For how many frames the sequence should be displayed. Children are unmounted if they are not within the time range of display. By default it will be Infinity
to avoid limit the duration of the sequence.
name
optional
You can give your sequence a name and it will be shown as the label of the sequence in the timeline of the Remotion preview. This property is purely for helping you keep track of sequences in the timeline.
layout
optional
Either "absolute-fill"
(default) or "none"
By default, your sequences will be absolutely positioned, so they will overlay each other. If you would like to opt out of it and handle layouting yourself, pass layout="none"
. Available since v1.4.
style
optional
CSS styles to be applied to the container. If layout
is set to none
, there is no container and setting this style is not allowed.
Cascading
You can nest sequences within each other and they will cascade.
For example, a sequence that starts at frame 60 which is inside a sequence that starts at frame 30 will have it's children start at frame 90.
Examples
All the examples below are based on the following animation of a blue square:
tsx
constMyVideo = () => {return <BlueSquare />;};
tsx
constMyVideo = () => {return <BlueSquare />;};
Delay
If you would like to delay the content by say 30 frames, you can wrap it in
<Sequence from={30}>
.
tsx
constMyVideo = () => {return (<Sequence from ={30}><BlueSquare /></Sequence >);};
tsx
constMyVideo = () => {return (<Sequence from ={30}><BlueSquare /></Sequence >);};
Trim end
We can clip some content so it only stays visible for a certain time by specifying a non-finite durationInFrames
number.
In this example, we wrap the square in <Sequence from={0} durationInFrames={45}>
and as you can see, it disappears after 45 frames.
Trim start
To trim the start of some content, we can pass a negative value to from
.
In this example, we wrap the square in <Sequence from={-15}>
and as a result, the animation has already progressed by 15 frames at the start of the video.
Trim and delay
What if you want to trim the start of the content and delay it at the same time?
You need to wrap the videos in two sequences. To the inner one we pass a negative start value from={-15}
to trim away the first 15 frames of the content, to the outer one we pass a positive value from={30}
to then shift it forwards by 30 frames.
tsx
constTrimAndDelayExample :React .FC = () => {return (<Sequence from ={30}><Sequence from ={-15}><BlueSquare /></Sequence ></Sequence >);};
tsx
constTrimAndDelayExample :React .FC = () => {return (<Sequence from ={30}><Sequence from ={-15}><BlueSquare /></Sequence ></Sequence >);};
Play Sequences sequentially
See the <Series />
helper component, which helps you calculate markup that makes sequences play after each other.
Adding a ref
You can add a React ref to an <Sequence>
from version v3.2.13
on. If you use TypeScript, you need to type it with HTMLDivElement
:
tsx
constMyComp = () => {constref =useRef <HTMLDivElement >(null);return (<Sequence from ={10}ref ={ref }>{content }</Sequence >);};
tsx
constMyComp = () => {constref =useRef <HTMLDivElement >(null);return (<Sequence from ={10}ref ={ref }>{content }</Sequence >);};
