totally strange,..

[Miranda]

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?

[Selur]

You are already using QTGMC.

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

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

[Miranda]

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

Here is a report from MediaInfo - is this correct?

[Selur]

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.

[Miranda]

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

[Selur]

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)

[Miranda]

Thank you, I will try this.
