After Effects (version 16.1.2) may crash when you import variable frame rate video clips created on the Nintendo Switch using the built-in video capture functionality. You may also face issues with some versions of Elgato capture software such as, Game Capture HD.

Workaround

If this affects a project or composition you are working on, use any of the following options:

• Transcode the affected video clips using Adobe Media Encoder to a supported high-quality video format such as ProRes, DNxHD, H.265, etc. Import the transcoded video file into After Effects  (version 16.1.2).
• If you are using an Elgato capture device with Game Capture HD or Video Capture for Windows, upgrade to the latest version of the Elgato software and recapture your video footage.
• Revert your After Effects installation back to (version 16.1.1) using the Adobe Creative Cloud app. To do this, in the Creative Cloud app, select After Effects > Manage > Other Version > 16.1.1. Once this version launches, you can import your After Effects project and capture video clips as needed.
