Upload the echo video (A4C view) as numpy array with shape=[30,299,299,1] ([time, height, width, 1]) and input the scale of the video in cm/pixel.
The video should be formatted in 30 fps and should be padded with 0 to be a square shape. The intensity should be between 0.0-1.0.
Or upload a DICOM video file. No value for scale is needed if DICOM is uploaded.
