Upload a source video
Use the Upload tab in a new clipping job for your original media.
Choose a video
Use a supported video file and check the size and duration limits shown by the upload flow. An original MP4 is a practical source for clipping.
Keep the upload page open
Wait until the upload is confirmed before starting analysis. A file selection is not a completed upload; failures should be retried from the source step.
Check your rights
Only process content you own or have permission to use. Uploaded files are private workspace media, not a public hosting service.
YouTube acquisition is separate
Account connection lists authorised channel content through the YouTube Data API. It cannot fix a download blocked by YouTube's network checks. Uploading your original file avoids that acquisition step.
