My recording upload failed

Go to your event’s Recording page. An upload that failed to send shows an error where the upload progress was. A file that uploaded but failed to process shows a message that processing failed last time.

OpenCEU accepts MP4, MOV, WebM, and MKV files. If your file is a different format, convert it before uploading again.

A large video file needs a stable connection for the whole upload. If your connection dropped partway through, that is the most common cause of a failed upload. Try again on a stable connection, ideally wired or strong Wi-Fi rather than a mobile hotspot.

Click Try again, or if the dropzone shows again, choose your video and upload it the same way as before. A retry fully replaces the failed attempt.

Processing takes roughly real time, so a 60-minute video takes roughly an hour to convert, transcribe, and draft a quiz. This is normal and does not mean anything failed. Watch the progress tracker on the Recording page.

If the same file fails to process a second time, contact support with your event link and the file format and size. Very large or unusual files may need help on the processing side.
