Deshaker and slow virtualdub script

[Sheik]

Hello,

when I open a file, add deshaker filter, configure it, and run pass 1, all is ok.

When i use the below script it is very slow. Any reason why?

VirtualDub.audio.filters.Clear();
VirtualDub.audio.SetSource(1);
VirtualDub.audio.SetMode(0);
VirtualDub.audio.SetInterleave(1,500,1,0,0);
VirtualDub.audio.SetClipMode(1,1);
VirtualDub.audio.SetEditMode(1);
VirtualDub.audio.SetConversion(0,0,0,0,0);
VirtualDub.audio.SetVolume();
VirtualDub.audio.SetCompression();
VirtualDub.audio.EnableFilterGraph(0);
VirtualDub.video.filters.Clear();
VirtualDub.video.filters.Add("Deshaker v3.1");
VirtualDub.SetStatus("Open");
VirtualDub.Open(U"F:\2019\DCIM\MOVIE\2015_0103_162907_001.MOV");
VirtualDub.SetStatus("Pass 1");
VirtualDub.video.SetInputFormat(0);
VirtualDub.video.SetOutputFormat(7);
VirtualDub.video.SetMode(3);
VirtualDub.video.SetSmartRendering(0);
VirtualDub.video.SetPreserveEmptyFrames(0);
VirtualDub.video.SetFrameRate2(0,0,1);
VirtualDub.video.SetIVTC(0, 0, 0, 0);
VirtualDub.video.SetCompression();
VirtualDub.video.filters.instance[0].Config("19|1|30|4|1|0|1|0|640|480|1|2|1000|1000|1000|1000|4|1|0|2|8|30|300|4|C:\\Users\\User1\\AppData\\Local\\Deshaker\\Deshaker.log|0|0|0|0|0|0|0|0|0|0|0|0|0|1|15|15|5|15|0|0|30|30|0|0|1|0|1|1|0|10|1000|1|88|1|1|20|5000|100|20|1|0|ff00ff");

Solved it myslf by installng virtuldub2 replacing virtualdub.
Problem refers to prior version only, i guess.
Thanks
