Well... first of all PAL is 25fps. Film is 24p (23.976fps).

Why do you need to convert your video to PAL?

Rather than dropping frames, deinterlace the video and convert it to 24 fps, then time-compress the audio to the speed equivalent to 25 and match the video to it.

Simple example

#VideoSource
LoadPlugin("C:\Users\Dawidos\Documents\Delphi_Projects\RipBot264\Tools\DGAVCDEC\DGAVCDecode.dll")
video=AVCSource("C:\Temp\RipBot264temp\job1\job1.dga")

#Deinterlace
LoadCplugin("C:\Users\Dawidos\Documents\Delphi_Projects\RipBot264\Tools\AviSynth plugins\Yadif\Yadif.dll")
video=yadif(video,mode=1,order=1).ChangeFPS(23.976).AssumeFPS(25)

#AudioSource
LoadPlugin("C:\Users\Dawidos\Documents\Delphi_Projects\RipBot264\tools\AviSynth plugins\NicAudio\NicAudio.dll")
audio=NicAC3Source("C:\Temp\RipBot264temp\job1\audio.1.ac3").TimeStretch(tempo=104.270937604270)


#AudioDub
AudioDub(video,audio)

Does the above script get rid of the duplicate frames? They're something you definitely do not want!
