Body: <p>Can anyone provide me with the ffmpeg code to convert deinterlaced 80's video to progressive video without any loss of quality - ideally where I could deinterlace only the interlaced fields(I use mediainfo to determine that) and basically preserve all the information in the video.</p>
  <p>Thanks

Comments.Text: 'without any loss of quality' is not really possible. You're going to have to interpolate half of each field, and no matter how you do that you're going to introduce signal loss. If you mean no `perceptible` loss of quality then you're asking a more realistic question.
