Chromium flags

We allow you to set the following flags in Chromium and Google Chrome since Remotion 2.6.5:

--disable-web-security​

This will most notably disable CORS among other security features.

note

Remotion will automatically append the --user-data-dir flag.

Via Node.JS APIs​

In getCompositions(), renderStill(), renderMedia(), renderFrames(), renderStillOnLambda() and renderMediaOnLambda(), you can pass chromiumOptions.disableWebSecurity.

Via CLI flag​

Pass --disable-web-security in one of the following commands: remotion render, remotion still, remotion lambda render, remotion lambda still.

Via config file​

Use setChromiumDisableWebSecurity().

tsx
Config.setChromiumDisableWebSecurity(true);
tsx
Config.setChromiumDisableWebSecurity(true);

--ignore-certificate-errors​

Results in invalid SSL certificates, such as self-signed ones, being ignored.

Via Node.JS APIs​

In getCompositions(), renderStill(), renderMedia(), renderFrames(), renderStillOnLambda() and renderMediaOnLambda(), you can pass chromiumOptions.ignoreCertificateErrors.

Via CLI flag​

Pass --ignore-certificate-errors in one of the following commands: remotion render, remotion still, remotion lambda render, remotion lambda still.

Via config file​

Use setChromiumIgnoreCertificateErrors().

tsx
Config.setChromiumIgnoreCertificateErrors(true);
tsx
Config.setChromiumIgnoreCertificateErrors(true);

--disable-headless​

Setting this flag will open an actual Chrome during render where you can see the render happen.

Via Node.JS APIs​

In getCompositions(), renderStill(), renderMedia() and renderFrames(), you can pass chromiumOptions.headless. You cannot set this option in Lambda.

Via CLI flag​

Pass --disable-headless in one of the following commands: remotion render, remotion still.

Via config file​

Use setChromiumHeadlessMode().

tsx
Config.setChromiumHeadlessMode(false);
tsx
Config.setChromiumHeadlessMode(false);

--gl​

Changelog
  • From Remotion v2.6.7 until v3.0.7, the default for Remotion Lambda was swiftshader, but from v3.0.8 the default is swangle (Swiftshader on Angle) since Chrome 101 added support for it.
  • From Remotion v2.4.3 until v2.6.6, the default was angle, however it turns out to have a small memory leak that could crash long Remotion renders.

Select the OpenGL renderer backend for Chromium. Accepted values:

  • "angle",
  • "egl",
  • "swiftshader"
  • "swangle"
  • null - Chromium's default

Default for local rendering: null.
Default for Lambda rendering: "swangle".

Via Node.JS APIs​

In getCompositions(), renderStill(), renderMedia(), renderFrames(), renderStillOnLambda() and renderMediaOnLambda(), you can pass chromiumOptions.gl.

Via CLI flag​

Pass --gl=swiftshader in one of the following commands: remotion render, remotion still, remotion lambda render, remotion lambda still.

Via config file​

tsx
Config.setChromiumOpenGlRenderer("swiftshader");
tsx
Config.setChromiumOpenGlRenderer("swiftshader");
