Script conversion 23.976 progressive to PAL 25

[Livesms]

I have a 23.976 fps video, progressive.
I want to convert to PAL 25.000 fps
How can I do this?
Is this way correct

DirectShowSource("D:\!!New\Matrix\TheMatrix.mp4")
AssumeFPS(25, 1, true)
SSRC(44100)

yeah, that'll do.

is this for re-encoding or just playback? if you want to play back at that rate, you can get reclock to do it for you.

you might also want to change the frame size - PAL is 720x576 typically.

In AviSynth documentation say about this method:
"The +4% speed up is conventionally used for displaying 24fps film on PAL television. The slight increase in pitch and tempo is readily accepted by viewers of PAL material."

But at last the pitch change can be avoided using:
AssumeFPS(25)
TimeStretch(tempo = (100.0*25.0*1001.0)/24000.0)

And that should beAssumeFPS(25, False) # Don't reclock the audio!
TimeStretch(tempo = (100.0*25.0*1001.0)/24000.0)
Either method will work well. The choice is a personal preference for a given source material.

People with a good absolute sense of pitch i.e. musicians, tend not to like the 4% upclocking.

Timestretch works by chopping the audio track into short segments and pasting them back together slightly offset, in this case 4%. The algorithm searches a specified window looking for the match with the lowest error. The default timing parameters are suited for current pop music. For different material other values may yield a better result. Material that has very little coorelatable patterning can give quite poor results i.e. you can hear where the pasting has happened.

I have a test CD with an Oboe Harp duet that simply will not work with TimeStretch no matter what timing I have tried, but it is expected, the track is intended to expose CD player jitter, and TimeStretch can generate some really good jitter.

I agree, and there are another method when the most important is the audio (a music concert for instance):
don't touch the audio, use ChangeFPS (25) or a more sophisticated method to insert/delete frames to preserve the video duration to match the audio duration.
