Device & OS: not provided
Scenario: Importing screen recordings or video files into a Clipchamp project for editing.

Solution 1Recommended

Convert the WEBM Recording to MP4 Format

Converting your WEBM file to MP4 ensures full compatibility with all versions of Microsoft Clipchamp and bypasses the unsupported file type error.

While Microsoft Clipchamp supports various media formats, specific versions or browser environments may lack the necessary codecs to process WEBM inputs. Converting the file to a universally accepted format like MP4 is the most effective and reliable workaround.

Select a Video Converter

Open a trusted online video converter (such as CloudConvert or FreeConvert) in your web browser, or launch a desktop conversion tool like HandBrake.

Upload the WEBM File

Click the 'Select File' or 'Upload' button in the converter interface and choose the unsupported WEBM recording from your computer.

Set Output to MP4

Locate the output format dropdown menu and select 'MP4'. If available, leave the video codec settings on 'H.264' for maximum compatibility.

Convert and Download

Click the 'Convert' button to start the process. Once finished, click 'Download' to save the new MP4 file to your local device.

Import into Clipchamp

Return to your Microsoft Clipchamp project, click the 'Import media' button at the top left, and select the newly converted MP4 file to successfully add it to your media library.

Convert the WEBM Recording to MP4 Format

Best Practice: Using MP4 format with the H.264 video codec and AAC audio codec is highly recommended for all Clipchamp projects to ensure smooth playback and optimal rendering speeds.

Frequently Asked Questions

Why does Microsoft Clipchamp show an unsupported file type error for my video?

This error occurs because the specific video container (like WEBM or MKV) or the internal audio/video codecs used to record the file are not natively supported by the version of Clipchamp or the web browser you are currently using.

What video file formats are officially supported by Microsoft Clipchamp?

Clipchamp primarily supports MP4, MOV, and WebM video files. However, support for WebM is largely dependent on using a compatible Chromium-based browser like Google Chrome or Microsoft Edge.

Will converting my WEBM video to MP4 cause a loss in quality?

If you use a high-quality converter and retain the original resolution and bitrate, the quality loss during the conversion from WEBM to MP4 will be negligible and unnoticeable in your final Clipchamp video project.
