npx remotion benchmark

available from v3.2.28

Measures render time by running a render multiple times, if desired with multiple compositions and concurrency values to compare against each other.

bash
npx remotion benchmark src/index.ts [composition-ids]

bash
npx remotion benchmark src/index.ts [composition-ids]

You can provide multiple composition IDs separated by comma, ex: npx remotion benchmark src/index.ts --codec=h264 Main,Canvas,CSS

If composition-ids is not passed, Remotion will let you select compositions from a list.

Flags

--runs

optional. Default is 3

Specify how many times video must be rendered. Default value is 3.

--concurrencies

optional

You can specify which concurrency value should be used while rendering the video. Multiple concurrency values can be passed separated by comma. Learn more about concurrency

--codec

optional

--audio-codecv3.3.42

optional

Set the format of the audio that is embedded in the video. Not all codec and audio codec combinations are supported and certain combinations require a certain file extension and container format. See the table in the docs to see possible combinations.

--disable-headless?

optional

Deprecated - will be removed in 5.0.0. With the migration to Chrome Headless Shell, this option is not functional anymore.

If disabled, the render will open an actual Chrome window where you can see the render happen. The default is headless mode.

--enable-multiprocess-on-linuxv4.0.42

Removes the --single-process flag that gets passed to Chromium on Linux by default. This will make the render faster because multiple processes can be used, but may cause issues with some Linux distributions or if window server libraries are missing.
Default: false until v4.0.136, then true from v4.0.137 on because newer Chrome versions don't allow rendering with the --single-process flag.
This flag will be removed in Remotion v5.0.

--number-of-gif-loops

optional

Allows you to set the number of loops as follows:

• null (or omitting in the CLI) plays the GIF indefinitely.
• 0 disables looping
• 1 loops the GIF once (plays twice in total)
• 2 loops the GIF twice (plays three times in total) and so on.

--color-spacev4.0.28

Color space to use for the video. Acceptable values: "default"(default since 5.0), "bt709" (since v4.0.28), "bt2020-ncl" (since v4.0.88), "bt2020-cl" (since v4.0.88), .
For best color accuracy, it is recommended to also use "png" as the image format to have accurate color transformations throughout.
Only since v4.0.83, colorspace conversion is actually performed, previously it would only tag the metadata of the video.

--hardware-accelerationv4.0.228

One of "disable", "if-possible", or "required" . Default "disable". Encode using a hardware-accelerated encoder if available. If set to "required" and no hardware-accelerated encoder is available, then the render will fail.

--offthreadvideo-cache-size-in-bytesv4.0.23

From v4.0, Remotion has a cache for <OffthreadVideo> frames. The default is null, corresponding to half of the system memory available when the render starts.
This option allows to override the size of the cache. The higher it is, the faster the render will be, but the more memory will be used.
The used value will be printed when running in verbose mode.
Default: null

--binaries-directoryv4.0.120

The directory where the platform-specific binaries and libraries that Remotion needs are located. Those include an ffmpeg and ffprobe binary, a Rust binary for various tasks, and various shared libraries. If the value is set to null, which is the default, then the path of a platform-specific package located at node_modules/@remotion/compositor-* is selected.
This option is useful in environments where Remotion is not officially supported to run like bundled serverless functions or Electron.
