Best strategy for de-telecining difficult 24PF footage?

So, I'm working on a project and some of it was shot 10 years ago on a Canon XA-10 with the dreaded 24PF format.


I'm working on a film in FCPX that's 24fps. I took the footage and did Reverse Telecine in Compressor. This solved the issue for most of the footage, but some of it had people walking past the camera, and there is still some slight interlacing after the Reverse Telecine in Compressor.


Any suggestions for what to try? I still have a backup of the original card I shot this on. Is there any way to somehow try to reverse it from the card rather than once it's been exported as 30i.


I know FCPX has a way to stop the conversion in importing, but that only works if it's from the camera. That option is greyed out if I try to import again.

If you are still experiencing interlacing artifacts after using the Reverse Telecine filter in Compressor, there are a few other things you can try to improve the footage:

  1. Use a different software: Instead of Compressor, try using a different software like Handbrake or Adobe Media Encoder to perform the Reverse Telecine process. Different software can produce different results.
  2. Adjust the Reverse Telecine settings: In Compressor, try adjusting the settings of the Reverse Telecine filter to see if it produces better results. You can experiment with different combinations of settings such as "Reverse Telecine Mode," "Field Order," and "Deinterlace Quality."
  3. Revert to the original footage: If you still have the original footage, try importing it into FCPX again and apply the Reverse Telecine filter directly in FCPX. This way, you can experiment with the different Reverse Telecine settings directly in FCPX and see if you can achieve better results.
  4. Hire a professional post-production service: If you are still struggling to achieve the desired results, consider hiring a professional post-production service that specializes in de-telecine and restoration. They will have access to specialized tools and techniques that can improve the quality of your footage.

Keep in mind that de-telecine is a difficult process, especially if the footage was shot in 24PF format. It's unlikely that you will be able to completely remove all interlacing artifacts, but by experimenting with different software and settings, you can minimize their impact on your final product.

Fairly obvious output from ChatGPT... not particularly useful or correct... ;-)
