Troubleshoot a failed video export
Check format, timing, memory and storage before retrying.
Check the preview and selection
If a source does not preview, try a known H.264 MP4. If it previews but cannot export, confirm that it is under 100 MB, no longer than 10 minutes and within 1920 × 1080. In trim mode, start must be before end. In frame mode, the timestamp must be smaller than the duration. Damaged files can fail even when their extension looks correct.
Keep resources available
The first operation downloads a processing engine of about 32 MB. An interrupted network connection can prevent that first load. After loading, video processing uses device CPU and memory. Close unnecessary heavy tabs, keep this tab open and avoid switching the device into sleep. A smaller source is often more effective than repeatedly retrying the same large file.
Understand time and storage limits
The app cancels work that takes too long, with a three-minute overall guard and an engine execution limit. Browser storage must also have enough free space for the result. A storage error means the export cannot be safely carried to its separate result page. Free some site or device storage, or try a browser with available quota.
Report useful details
Contact support with the browser name and version, the input format, approximate duration and the displayed error. Do not send a private video merely to describe a problem. A success message is shown only after a nonempty output has been created and stored. External account verification and advertising approval are separate from video processing success.
