You can’t IVTC it successfully, because it’s field blended. You need to use something such as SRestore(). There are alternatives, but they are all much of a muchness.
LoadCplugin("C:\Program Files (x86)\AviSynth\plugins\yadif.dll") Mpeg2Source() AssumeTFF() Yadif(mode=1)#or QTGMC or whatever SRestore()
I get confused about the history of the different TV versions. Was this the version that was edited/reconstructed in PAL and then converted to NTSC or was that the RIC? You might have to adjust the script to specify a frame-rate. At present, it’s returning 25fps.
Cheers for that, I’ll have a look.
For the history of the RIC, I know multiple tapes of different airings were used to add in the missing bits to a retail VHS capture. Whether the project was completed in PAL and an NTSC conversion was done, or the other way around, I don’t know.
