- Product
- OneDrive
- Device & OS
- not provided
- Scenario
- Sharing large video files, specifically MOV formats, with other users via OneDrive links.
- Observed behavior
- Shared videos appear as a black screen or fail to play for recipients on phones and computers, even though the files remain fully accessible and playable for the sender.
Ensure you have a stable internet connection and verify that the original video file plays correctly on your local device's media player before attempting to convert or share it.
Convert MOV Videos to MP4 Format
Converting your large MOV files to MP4 format ensures better compatibility with OneDrive and SharePoint web players, preventing black screens.
Large MOV files often struggle to stream reliably through SharePoint and OneDrive web interfaces. MP4 is universally supported and highly optimized for web playback across different devices and operating systems.
Use a trusted video converter tool or video editing software to export your original MOV video as an MP4 file.
Log in to your OneDrive account, click the 'Upload' button, and select the newly converted MP4 file.
Right-click the MP4 file in OneDrive, select 'Share', and copy the link to send to your recipients.

Test Playback with an 'Anyone' Sharing Link
Create an open sharing link in a new folder to verify that the video is accessible and not restricted by specific folder permissions.

Frequently Asked Questions
Why do MOV files show a black screen on OneDrive?
MOV files, especially large ones, can struggle to stream reliably through OneDrive and SharePoint's web video player. This lack of web optimization often results in playback errors or black screens for recipients.
What is the best video format for sharing on OneDrive?
MP4 is universally recommended for sharing on OneDrive because it offers excellent compression, smaller file sizes, and high compatibility across all modern web browsers and mobile devices.
How do I know if my shared OneDrive video is working for others?
You can test your shared video by generating an 'Anyone with the link' sharing URL and opening it in an incognito or private browsing window, or by testing it on a separate mobile device.
Can recipients download the video if it won't play online?
Yes, if a video fails to stream directly in the web browser, recipients can usually click the 'Download' button at the top of the OneDrive interface to save the file locally and play it using their device's native media player.
