If uploading to YouTube fails, it may be due to the following reasons.
Unauthorized upload
To directly upload videos to YouTube through Filmora, you need to log in to your account within Filmora and authorize it. If the upload fails and you see the message "Your YouTube account authorization has expired. Please log in again and authorize," please log out from the "Export - YouTube" module in Filmora, then log in again and check the "View your YouTube account" and "Manage your YouTube videos" authorization options. Alternatively, you can try modifying your account permissions directly in your Google Account Permission.
Exceeding upload limits
To ensure user safety, YouTube limits the number of videos a channel can upload within 24 hours. The specific limit may vary depending on your account. If you receive an error message stating "Upload limited," please try uploading again after 24 hours.
For more details, you can refer to the "Common Upload Errors" section. If none of the above solutions resolve your issue, you can contact our technical support team through the Wondershare Help Center.
