totally strange,..

I got InterFrame to work last week with Interlaced set to TopFrame for ProRes, no QTGMC and InterFrame to 29.97.

But you mentioned it would look better with QTGMC?

You are already using QTGMC. Wink

It'll send you a link to a new dev version in a ~5min, then try with that version:
  • loading your 25i source
  • setting "Filtering->Vapoursynth->Misc->Script->Finter interlace handling' to 'QTGMC(preset="Fast")'.
  • enabling "Filtering->Vapoursynth->Frame->Interpolation"
  • setting "Filtering->Vapoursynth->Frame->Interpolation" to "Interframe/SVP"
  • setting "Filtering->Vapoursynth->Frame->Interpolation->Interframe/SVP->FPS" to "59.94"
  • setting "Filtering->Vapoursynth->Frame->Interpolation->Interframe/SVP->Tuning" to "smooth"
  • doing the rest of your settings (make sure encoder is set to interlaced output)

It is now processing the video file Smile

I will let you know the results when processing is complete in 18 hours time.

It has worked - and very well. The file looks amazing. Thank you for your help!

Here is a report from MediaInfo - is this correct?

It should. The script create 29.97i content like you wanted, so this is what I would expect as output.

Thanks. Can I use the same method to create clean 25i footage from the original 25i master?
Reply

Do you want to reencode 25i to 25i or something else?
(when converting 25i to 25i you could use "Filtering->Vapoursynth->Misc->Script->Finter interlace handling' to 'QTGMC(preset="Fast")', but using interframe doesn't make sense then)

Thank you, I will try this.
