As mentioned above, the upper and lower fields are displayed at slightly different times, with a very short delay in between. One second of a 60 FPS interlaced video contains 30 upper and 30 lower fields.
Such two fields are usually called “upper field” (odd scan lines) and “lower field” (even scan lines).Įssentially, interlaced video is a stream of pairs of upper and lower fields. Typically, the field with the odd scan lines is displayed first, and then, a bit later, the field with the even scan lines is displayed.
Interlaced and progressive scan types are used in two corresponding formats of a video representation.Ī progressive video clip contains a set of frames, each of which shows the whole image of the scene, with all its scan lines present in each frame.Īn interlaced video clip on the other hand shows odd and even scan lines as two separate images, or fields also displayed at different moments in time. It just means that you are likely working with interlaced footage. Have you got a squished and stretched image inside Neat Video’s window? Or maybe even two such images one above another? There is nothing wrong with your footage or Neat Video and your denoised video will not look anything like that.
