No more FFmpeg installation!β
Now, when you are rendering a video and don't have FFmpeg installed, Remotion will download a copy for you.
Previously, installing FFmpeg required 7 steps on Windows and took several minutes when using Homebrew on macOS.
When deploying Remotion on a server, you can now also let Remotion install FFmpeg for you using the ensureFfmpeg() API or the npx remotion install ffmpeg command. Learn more about FFmpeg auto-install here.
New @remotion/google-fonts packageβ
It is now easy to import Google Fonts into Remotion! @remotion/google-fonts takes care of correct loading, and is fully type-safe!
New @remotion/motion-blur packageβ
This package contains two components: <Trail> and <CameraMotionBlur>, assisting you with achieving awesome motion blur effects!
A quick demo of what is now called <Trail>:
New @remotion/noise packageβ
This package offers easy, type-safe, pure functions for getting creative with noise. Check out our playground to see what you can do with it!
A video demo of how you can create interesting effects with noise:
New @remotion/paths packageβ
This package offers utilities for animating and manipulating SVG paths! With 9 pure, type-safe functions, we cover many common needs while working with SVG paths:
Quick Switcherβ
By pressing Cmd+K, you can trigger a new Quick Switcher. It has three functions:
- Fuzzy-search for a composition to jump to that composition.
- Type
> followed by an item in the menu bar to trigger that action.
- Type
? followed by a search term to query the docs.
Remotion Coreβ
<Sequence> makes from optional, accepts style and refβ
<Sequence from={0}> can now be shortened to <Sequence>. Our ESLint plugin was updated to suggest this refactor automatically.
You can now also style a sequence if you did not pass layout="none".
A ref can be attached to <Sequence> and <AbsoluteFill>.
Video and Audio support loop propβ
The <Video> and <Audio> components now support the loop property.
Previewβ
New CLI outputβ
When starting the Remotion Preview, it now shows on which URL the preview is running. The Webpack output is now also cleaner.
Pinch to Zoomβ
If your device supports multitouch, you can now pinch to zoom the composition. Alternatively, you can hold Ctrl/Cmd and use your scrollwheel to zoom.
Using two fingers, you can move the canvas around and pressing 0 will reset the canvas. For the latter, there is also a button in the top-right corner that you can click.
Search the docs from the Remotion Previewβ
Pressing ? to reveal the keyboard shortcuts now has a secondary function: You can type in any term to search the Remotion documentation!
Shorter commandsβ
Previously, a Remotion CLI command looked like this:
bash
npx remotion render src/index.tsx my-comp output.mp4
bash
npx remotion render src/index.tsx my-comp output.mp4
We now allow you to skip the output name, in this case the render would land in out/my-comp.mp4 by default:
bash
npx remotion render src/index.tsx my-comp
bash
npx remotion render src/index.tsx my-comp
You can also omit the composition name and Remotion will ask which composition to render:
bash
npx remotion render src/index.tsx
bash
npx remotion render src/index.tsx
Experimental: We might change the behavior to rendering all compositions in the future.
Finally, you can also omit the entry point and Remotion will take an educated guess!
If you deviate from the defaults of our templates, you can set an entry point in your config file and leave it out from Remotion commands.
Auto-reload environment variablesβ
If you change values in your .env file, the Remotion Preview will reload and pick them up without having to restart.
Signal that Remotion Preview disconnectedβ
When quitting the Remotion Preview using Ctrl+C, for example to render a video, A new popup will signalize that Fast Refresh will not work anymore.
Renderingβ
--muted renderβ
This new flag can be passed to a render to ignore the audio. If you know that your video has no audio, this can make your render faster.
--enforce-audio-trackβ
When no audio was detected in your video, the audio will now be dropped (except on Lambda). With this new flag, you can enforce that a silent audio track is added.
--audio-bitrate and --video-bitrateβ
These flags allow you to set a target bitrate for audio or video. Those flags are not recommended though, use --crf instead.
--height and --width flagsβ
Using these flags, you can ignore the width and height you have defined for your output, and override it. The difference to --scale is that the viewport and therefore the layout may actually change.
Obtain slowest framesβ
If you add --log=verbose, the slowest frames are shown in order, so you can optimize them. Slowest frames are also available for renderMedia() using the onSlowestFrames callback.
Negative numbers when rendering a stillβ
When rendering a still, you may now pass a negative frame number to refer to frames from the back of the video. -1 is the last frame of a video, -2 the second last, and so on.
Override FFmpeg commandβ
The FFmpeg command that Remotion executes under the hood can now be overriden reducer-style.
Server-side renderingβ
Resuming renders if they crashβ
If a render crashes due to being resource-intensive (see: Target closed), Remotion will now retry each failed frame once, to prevent long renders from failing on low-resource machines.
Previously, the progress for rendering and encoding was reported individually. There is a new field, simply named progress, in the onProgress callback that you can use to display progress without calculating it yourself.
Easier function signature for bundle()β
Previously, bundle() accepted three arguments: entryPoint, onProgress and options.
Old bundle() signature
ts
import { bundle } from "@remotion/bundler";
bundle("./src/index.ts", (progress) => console.log(progress), {
publicDir: process.cwd() + "/public",
});
Old bundle() signature
ts
import { bundle } from "@remotion/bundler";
bundle("./src/index.ts", (progress) => console.log(progress), {
publicDir: process.cwd() + "/public",
});
Since getting the progress was less important than some of the options, bundle() now accepts an object with options, progress callback and entryPoint altogether:
New bundle() signature
ts
import { bundle } from "@remotion/bundler";
bundle({
entryPoint: "./src/index.ts",
onProgress: (progress) => console.log(progress),
publicDir: process.cwd() + "/public",
});
New bundle() signature
ts
import { bundle } from "@remotion/bundler";
bundle({
entryPoint: "./src/index.ts",
onProgress: (progress) => console.log(progress),
publicDir: process.cwd() + "/public",
});
The previous signature is still supported.
<Thumbnail> componentβ
The new <Thumbnail> component is like the <Player>, but for rendering a preview of a still. You can use it to display a specific frame of a video without having to render it.
tsx
import { Thumbnail } from "@remotion/player";
const MyApp: React.FC = () => {
return (
<Thumbnail
component={MyComp}
compositionWidth={1920}
compositionHeight={1080}
frameToDisplay={30}
durationInFrames={120}
fps={30}
style={{
width: 200,
}}
/>
);
};
tsx
import { Thumbnail } from "@remotion/player";
const MyApp: React.FC = () => {
return (
<Thumbnail
component={MyComp}
compositionWidth={1920}
compositionHeight={1080}
frameToDisplay={30}
durationInFrames={120}
fps={30}
style={{
width: 200,
}}
/>
);
};
Player frameupdate eventβ
In addition to timeupdate, you can subscribe to frameupdate, which fires whenever the current frame changes. You can use it for example to render a custom frame-accurate time display.
Player volume slider is responsiveβ
If the Player is displayed in a narrow container, the volume control now goes upwards instead of to the right, in order to save some space.
Get the scale of the Playerβ
Using the imperative getScale() method, you can now see how big the displayed size is in comparison to the canvas width of the component.
Controls are initially shownβ
On YouTube, the video always starts with controls shown and then they fade out after a few seconds. We have made this the default behavior in Remotion as well, because users would often not realize that the Player is interactive otherwise. You can control the behavior using initiallyShowControls.
Play a section of a videoβ
Using the inFrame and outFrame props, you can force the Remotion Player to only play a certain section of a video. The rest of the seek bar will be greyed out.
Using renderPlayPauseButton and renderFullscreenButton, you can customize the appearance of the Player more granularly.
Start player from an offsetβ
You can define the initialFrame on which your component gets mounted on. This will be the default position of the video, however, it will not clamp the playback range like the inFrame prop.
New prefetch() APIβ
In addition to the Preload APIs, prefetch() presents another way of preloading an asset so it is ready to display when it is supposed to appear in the Remotion Player.
Prefetching API
tsx
import { prefetch } from "remotion";
const { free, waitUntilDone } = prefetch("https://example.com/video.mp4");
waitUntilDone().then(() => {
console.log("Video has finished loading");
free(); // Free up memory
});
Prefetching API
tsx
import { prefetch } from "remotion";
const { free, waitUntilDone } = prefetch("https://example.com/video.mp4");
waitUntilDone().then(() => {
console.log("Video has finished loading");
free(); // Free up memory
});
Video and audio tags will automatically use the prefetched asset if it is available. See @remotion/preload vs. prefetch() for a comparison.
Remix templateβ
The Remix template is our first SaaS template! It includes the Remotion Preview, the Player and Remotion Lambda out of the box to jumpstart you with everything you need to create your app that offers customized video generation.
Get started by running:
bash
yarn create video --remix
bash
yarn create video --remix
bash
pnpm create video --remix
bash
pnpm create video --remix
Lambda improvementsβ
Webhook supportβ
You can now send and receive a webhook when a Lambda render is done or has failed. Examples for Next.js and Express apps have been added and our documentation page features a way to send a test webhook.
Payload limit liftedβ
Previously, the input props passed to a Lambda render could not be bigger than 256KB when serialized. Now, this limit is lifted, since if the payload is big, it will be stored to S3 instead being passed directly to the Lambda function.
Lambda artifact can be saved to another cloudβ
The output videos generated by Lambda can now be saved to other S3-compatible protocols such as DigitalOcean Spaces or Cloudflare R2.
Deleting a render from Lambdaβ
The new deleteRender() API will delete the output video from the S3 bucket, which you previously had to do through the console or with the AWS SDK.
The following options are now optional:
Benchmark commandβ
The new npx remotion benchmark helps you compare different render configurations and find out which one is the fastest. Currently, you can compare different codecs, compositions and concurrency values. Each configuration is run multiple times in order to increase confidence in the results.
New guidesβ
We have added new guides that document interesting workflows for Remotion:
We try to avoid jargon, but we have also created a Remotion Terminology page to define some commonly used terms. When using these terms, we will from now link to the terminology page for you to read about it.
Better structure and naming in templatesβ
The file that was previously called src/Video.tsx in templates is now called src/Root.tsx, because it did not contain a video, but a list of compositions. That component was also renamed from RemotionVideo to RemotionRoot. The new naming makes more sense, because that component is passed into registerRoot().
Notable improvementsβ
Get the duration of a GIFβ
The new function getGifDurationInSeconds() allows you to get the duration of a GIF.
Lottie animation directionβ
Using the new direction prop, you can play a Lottie animation backwards.
Lottie embedded imagesβ
Should a Lottie animation contain an embedded image, it will now be properly awaited.
Temporary directory Cleanupβ
The temporary directory that Remotion creates is now completely cleaned up after every render.
Parallel encoding turned off if memory is lowβ
Parallel encoding will not be used when a machine has little free RAM. You can also force-disable it using disallowParallelEncoding.
