Answers.Text: Thanks for your answer, I will give it a try, though unfortunately it seems this tool does not read .mts files but QuickTime files, which will add an additional step to the process. But if it works well, I guess I'll live with it!

Body: <p>Many Canon AVCHD camcorders record 24fps in a format they call PF24, which essentially disguises the 24 fps in a 60i stream by applying 3:2 pulldown.</p>
  
  <p>Unfortunately they do this so well that to my knowledge editors can't detect it automatically and apply the reverse transformation. I have verified that this is true for Sony Vegas Pro 10 on Windows and FCPX on OS X, which treat these files as regular 60i material. When these clips are added to a 24p timeline they get the regular deinterlacing treatment, which looks awful.</p>
  
  <p>Are there any tools (command line preferred) that can take a .MTS file with PF24 material and perform the inverse telecine process to convert to native 24p with minimal quality loss?</p>
