Preview uncompressed RGB source doesn't work

[Selur]

Okay, your content is interlaced top field first with lots of duplicate frames, this is the reason why VIVTC, which is meant for telecined (3:2 pulldown) and similar content, does not remove the combing artifacts.
Boobing and looking at the content I get: AAABBCCCDDEEE... as a pattern.
So 4 real frames end up as 10 frames when bobbing to, so your content is probably contains 23,976 full progressive frames which were interlaced and then duplicated to get to 29.976fps.
If you only want a digital version I would recommend to:

• load the source
  
• let Hybrid know that the content is 'top field first' (tff) interlaced
  
  1. enable 'Filtering->(De-)Interlace/Telecine->Deinterlace/Telecine Settings->Overwrite input scan type to'
     
  2. set 'Filtering->(De-)Interlace/Telecine->Deinterlace/Telecine Settings->Overwrite input scan type to' to 'top field first'
     
• use QTGMC Vapoursynth in Bob mode to get rid of the combing artifacts
  
  1. set 'Filtering->(De-)Interlace/Telecine->Deinterlace/Telecine Settings->Deinterlacer' to 'QTGMC (Vapoursynth)'; this should happen automatically assuming you didn't mess with the default settings.
     
  2. enable 'Filtering->(De-)Interlace/Telecine->QTGMC Vapoursynth->Bob' (this way the output would be 59.97fps)
     
• use sRestore to throw away the duplicates to reach 23.776fps
  
  1. enable 'Filtering->Vapoursynth->Frame->Reduction->Restore' (sRestore is the only filter there atm.)
     
  2. set 'Filtering->Vapoursynth->Frame->Reduction->Restore->sRestore->Frate' to '23.976'
     

after some thinking,... -> Sorry, I was wrong this shoudl work fine with VIVTC, there is a bug. I'm looking into it.
