Body: <p>I've got a final version of a movie I co-produced, ca. 20 minutes in a below 3GB file. There's a few-second-long fragment that needs to be deinterlaced, but I can't do it on a project file before rendering, since the original director/editor is a weirdo, so I have to make do with the version I have.</p>
  
  <p>Therefore I split the movie to isolate the fragment I need to deinterlace, and I intend to concatenate it later on.</p>
  
  <p>I used this advice: <a href="https://askubuntu.com/questions/866186/how-to-get-good-quality-when-converting-digital-video">https://askubuntu.com/questions/866186/how-to-get-good-quality-when-converting-digital-video</a> and it works well, however it results in a 50 fps file instead of 25 fps (which is understandable due to the intricacies of the process, but not compatible with my original file) and quite different quality settings.
  How would I formulate the command to get the output file compatible with the source file in order to concatenate? Should it be two-pass to take advantage of 50 fps deinterlacing process?</p>
  
  <p>Thanks in advance, Antoni.</p>

Title: How to deinterlace a fragment of a movie and retain the exact original quality with FFmpeg
UserDisplayName: baskak
ThreadText: # How to deinterlace a fragment of a movie and retain the exact original quality with FFmpeg
  
  (Asked by: username_0 on 2018-11-10)
  
  I've got a final version of a movie I co-produced, ca. 20 minutes in a below 3GB file. There's a few-second-long fragment that needs to be deinterlaced, but I can't do it on a project file before rendering, since the original director/editor is a weirdo, so I have to make do with the version I have.
  
  Therefore I split the movie to isolate the fragment I need to deinterlace, and I intend to concatenate it later on.
  
  I used this advice: <https://askubuntu.com/questions/866186/how-to-get-good-quality-when-converting-digital-video> and it works well, however it results in a 50 fps file instead of 25 fps (which is understandable due to the intricacies of the process, but not compatible with my original file) and quite different quality settings.
  How would I formulate the command to get the output file compatible with the source file in order to concatenate? Should it be two-pass to take advantage of 50 fps deinterlacing process?
  
  Thanks in advance, Antoni.
