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"
  • "vulkan" (from Remotion v4.0.41)
  • "angle-egl" (from Remotion v4.0.51)

The default is null, letting Chrome decide, except on Lambda where the default is "swangle"
