Avisynth and 3:2 pulldown when playback

[BodyMaker]

Can anyone show me an example of the script i need to write to perform 3:2 pulldown when playback, But not a hard pulldown.

I think i have to use :-

Pulldown, Telecide, Decimide

But im not sure which ? This is my normal kind of script

LoadPlugin("C:\Program Files\NimoCodec Pack\Mpeg2dec\MPEG2DEC.dll")
xxxxSource("D:\Video Editing\Test.xxx")
BicubicResize(448,432,1/3,1/3,8,0,560,304)
AddBorders(16,16,16,32)
ResampleAudio(44100)

Trueman where are you when i need you lol

The 3:2 pulldown you are referring to is a flag which is set in the mpg video stream. Avisynth simply frameserves your source to the encoder. Since the video is not even encoded to mpg yet, this is not something that avisynth can or even should do.

When encoding with encoders that don't support the 3:2 pulldown flag setting ie: older versions of CCE; simply encode at 23.976fps but encode the audio and video separately. Run your video stream through pulldown.exe and multiplex the resulting m2v (video stream) with your encoded audio. The result will be the same as if you had encoded an mpg with the "3:2 pulldown while playback" option set in TMPGenc.

You can get pulldown.exe from the tools section of this site. you may want to pick up the gui as well to make things easier.

Thanks for the reply Adam

Thats just exactly the way im doing it at the moment :-

Avi---->Avisynth---->CCE---->Pulldown.exe---->Multiplex

But for some reason a lot of my resulting Output Mpeg files, ( But not all ) don't seem to like it, They jerk around on playback on my standalone dvd player

Where as if i use TMPGenc they are fine, But the thing is i like the output Quality of CCE much better

I thought seeing as Tmpeg does Pulldown with playback and not a hard pulldow that this was the problem, Because its the only thing that i can see thats any different

I have the new version of CCE that supports pulldown ( with the bug fix ) but when i check the Pulldown box and encode the resulting file still comes out 23,976 ?

Any ideas thanks

When i say jerk around i dont mean jerk around like a bad encode

The whole picture shakes from left to right constantly

Which is the right setting for block scanning order for avi ?

Zig zag or alternate ?

[adam]

Ziggzagg is recommended for progressive video and alternate is recommended for interlaced matieral, but this can change if you use a modified Q Matrix. This definitely isn't the cause of your problem though.

Make sure in CCE that you tell it to encode progressive or interlaced according to your source. This could possibly cause jerky playback if set incorrectly but I doubt this is your problem as well.

Are you perhaps using the 16:9 ratio flag in CCE? This is not supported by the majority of SVCD compatible dvd players and the most common problems are bad aspect ratio or shaky playback.

[BodyMaker]

I think you might have cracked it I always use 16:9 and some times when its shaking the picture seems over to one side more than the other

I will give 4:3 a go and see how i get on
