contentneeds at least one text, image or video item.- Every image, video and audio item in
contentnames itsrole. - Input limits: up to 9 images, 3 videos and 3 audio items in
content, with no limit on the total. Each video and audio item runs 2 to 15 seconds. Videos add up to at most 15 seconds, and audio to at most 15 seconds. Lengths are checked before the task is created when the file can be measured (422input_duration_out_of_range). Task type and drafts are not supported. - Image pixel size and aspect ratio, and video resolution and frame rate, are not checked when the request is made: the model checks them when the task runs, and a file it refuses usually fails the task with
input_media_invalid(otherwisegeneration_failed); the task is not charged. first_frameandlast_frameimages (at most one each) cannot be combined with reference images, videos or audio, and alast_frameneeds afirst_frame.- Audio items need at least one image or video in
content. - Prompt text must not contain inline
--flagparameters.
