[HELP] 25i to 29.97i with interpolation
25p to 29.97i:
  • loading a 25p 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"
  • enabling "Filtering->Vapoursynth->Frame->Interpolation->Interframe/SVP->GPU" (if your gpu is supported by SVP)
  • settinng "Prores->Interlacing" to either 'top field first' or 'bottom field first'
  • Vapoursynth script now looks like this:
    # Imports
    import vapoursynth as vs
    import os
    import sys
    # getting Vapoursynth core
    core = vs.core
    # Import scripts folder
    scriptPath = 'i:/Hybrid/64bit/vsscripts'
    sys.path.insert(0, os.path.abspath(scriptPath))
    # Loading Plugins
    core.std.LoadPlugin(path="i:/Hybrid/64bit/vsfilters/FrameFilter/Interframe/svpflow2_vs64.dll")
    core.std.LoadPlugin(path="i:/Hybrid/64bit/vsfilters/FrameFilter/Interframe/svpflow1_vs64.dll")
    core.std.LoadPlugin(path="i:/Hybrid/64bit/vsfilters/SourceFilter/LSmashSource/vslsmashsource.dll")
    # Import scripts
    import havsfunc
    # source: 'G:\TestClips&Co\files\test.avi'
    # current color space: YUV420P8, bit depth: 8, resolution: 640x352, fps: 25, color matrix: 470bg, yuv luminance scale: limited, scanorder: progressive
    # Loading G:\TestClips&Co\files\test.avi using LWLibavSource
    clip = core.lsmas.LWLibavSource(source="G:/TestClips&Co/files/test.avi", format="YUV420P8", stream_index=0, cache=0, fpsnum=25, prefer_hw=0)
    # Setting color matrix to 470bg.
    clip = core.std.SetFrameProps(clip, _Matrix=5)
    clip = clip if not core.text.FrameProps(clip,'_Transfer') else core.std.SetFrameProps(clip, _Transfer=5)
    clip = clip if not core.text.FrameProps(clip,'_Primaries') else core.std.SetFrameProps(clip, _Primaries=5)
    # Setting color range to TV (limited) range.
    clip = core.std.SetFrameProp(clip=clip, prop="_ColorRange", intval=1)
    # making sure frame rate is set to 25
    clip = core.std.AssumeFPS(clip=clip, fpsnum=25, fpsden=1)
    clip = core.std.SetFrameProp(clip=clip, prop="_FieldBased", intval=0)
    # adjusting frame count with Interframe/SVP
    clip = havsfunc.InterFrame(clip, Tuning="smooth", NewNum=60000, NewDen=1001, GPU=True) # new fps: 59.94
    # converting progressive to interlaced for 'progressive to interlaced (1)'
    clip = core.std.SeparateFields(clip=clip, tff=True)
    clip = core.std.SelectEvery(clip=clip, cycle=4, offsets=[0, 3])
    clip = core.std.DoubleWeave(clip=clip, tff=True) # resolution 640x352
    clip = core.std.SelectEvery(clip=clip, cycle=2, offsets=0) # new fps: 29.97
    clip = core.std.SetFrameProp(clip=clip, prop="_FieldBased", intval=2)
    # adjusting output color from: YUV420P8 to YUV422P10 for ProResModel
    clip = core.resize.Bicubic(clip=clip, format=vs.YUV422P10, range_s="limited")
    # set output frame rate to 29.97fps
    clip = core.std.AssumeFPS(clip=clip, fpsnum=30000, fpsden=1001)
    # Output
    clip.set_output()
    for me

Adding a new job and processing that job, creates:

here.

=> works here.
