FrameRateComverter issue
Trying to change FPS using "FrameRateConverter" after QTGMC (no Bob) .
Regardless of specifying parameters (in my case Frame Rate (num/den - 48000/1001 ) and Windows version (tried Win7 and Win10),
it throws an error "... -> 2020-10-21@12_05_26_2210_03_video crashed: ERROR: D:\Hybrid_test\Gastown-tilt_2020-10-21@12_05_26_2210_03.avi was not created!
Aborting '2020-10-21@12_05_26_2210_03_video' due to: ERROR: D:\Hybrid_test\Gastown-tilt_2020-10-21@12_05_26_2210_03.avi was not created!" (see attached).

Please, read the 'Infos needed to fix&reproduce bugs,..'-sticky before you post about a problem.
First time have ever seen someone aiming for 48000/1001. Smile

Avisynth crashes with:
mt_merge : clips should have identical bit depths
(C:\Program Files\Hybrid\32bit\avisynthPlugins\FrameRateConverter.avsi, line 228)
(D:\Hybrid_test\encodingTempSynthSkript_2020-10-21@12_16_49_9310.avs, line 15)
looking at the used script:
LoadDLL("C:\Program Files\Hybrid\32bit\avisynthPlugins\libfftw3f-3.dll")
Import("C:\Program Files\Hybrid\32bit\avisynthPlugins\FrameRateConverter.avsi")
# loading source: D:\Hybrid_test\
#  color sampling YUY2@8, matrix: pc601, scantyp: progressive, luminance scale: full
# current resolution: 720x480
# filtering
return last
my guess is that FrameRateConverter has a problem with YUY2.
-> seems like in the current version ony YV12, YV24, Y8 are supported.

Will send you a link to a dev version for testing in ~15min,..

Actually for 29.97 to 23.976 I prefer "Bobbed" QTGMC, that gives me "full' 59.94 frames and than 96000/1001 with Select Every 4,0.
Seems crazy to me, but if it works for you: go for it. Smile

What would you suggest?
What are the characteristics of your source and what do you aim for?
Actually this approach "48000/1001" I borrowed from Fizics  MVTools blog (original sample for PAL to NTSCL - 60000/1001)
Another approach exactly for "FrameRateConverter" is FrameRateConverter(Preset="Slow", FrameDouble=false, NewNum=24000, NewDen=1001)
That does not answer my question at all,...
Sorry, I replied before seen your question.

The goal is to convert 29.97 to 23.976
According to the mediainfo your source should be telecined, then IVTC (VIVTC, TIVTC) is the default way.
If your source isn't telecined (and you still want to to for 23.976), the default way should be:
a. bob deinterlace with the deinterlacer of your choice
b. use sRestore and aim for 23.976

Some additional vinverse and similar filtering might still be a good idea depending on the source.
