Hi all,
I am using Virtualdub scripting and I need to apply a Inverse Telecine with 1.9.1 release .
But the interpolate fiter config is not documented in http://www.virtualdub.org/docs/vdscript.txt
Here is some code:
| QUOTE |
declare myfilter;
myfilter=VirtualDub.video.filters;
myfilter..Add("interpolate");
myfilter.instance[0].Config(a,b,c) ;
|
I understand that Config have 3 parameters ...
Thanks all
PS: using setFrameRate crash |

I don't have an answer for you for this topic but I noticed that there are two dots in the "myfilter.add" part of your code. Is that a syntax error or is there suppose to be a double dot there? |

A little mistake in the message.
And still no idea of the needed config parameters of "interpolate" filter (which was old Inverse Telecine feature of changing frame rate.
Any idea ? |

You don't have to use the interpolate filter for IVTC; it is not its replacement. The IVTC filter is.
If you are not sure how to configure a certain filter ina script an easy way to figure this out is to create the an instance of the filter within VirtualDub, configure it, and then save a processing settings file, which you can view in a text editor.

Great !
wonderful feature I didn't known . But when I execute it in a script frame number are inchanged instead of decreasing to a 25fps .
I am trying to changing fps in a script, from 60p to 25p.
I test it using filter menu. No problems but when I am running the saved process in a script => same frames number... So the last frame is repeted during most of the end of the stream.
here is my script:
| CODE |
//$ 1920*1080p60 => 640*480p25
//$ video
VirtualDub.Open(VirtualDub.params[0]);
//$ Audio
VirtualDub.audio.SetSource(VirtualDub.params[1],"");
//------------------------------ End of gen code
VirtualDub.audio.SetMode(0);
VirtualDub.audio.SetInterleave(1,500,1,0,0);
VirtualDub.audio.SetClipMode(1,1);
VirtualDub.audio.SetConversion(0,0,0,0,0);
VirtualDub.audio.SetVolume();
VirtualDub.audio.SetCompression();
VirtualDub.audio.EnableFilterGraph(0);
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.Clear();
VirtualDub.video.filters.Add("interpolate");
VirtualDub.video.filters.instance[0].Config(0, 25, 0);
VirtualDub.video.filters.Add("resize");
VirtualDub.video.filters.instance[1].Config(640,360,0,4,3,1,640,480,4,3,1,7,1,0x000000);
VirtualDub.audio.filters.Clear();
//------------------------------ End of gen code
//$ Save
VirtualDub.SaveAVI(VirtualDub.params[0]+"_vga25.avi");
VirtualDub.audio.filters.Clear();

I didn't mean to say that you should copy the whole processing files settings file. Only that you can figure out how the filter should be configured that way...

That's right.
The point is now that the filter have 2 different behavior, One correct using interface, one not correct in scripting. This is why I copied the most part of the generated script.
My probleme is maybe an interaction - implicit or not - with one of these routines. Frame number may change (I reduce fps) but not.
sorry |

You need to reset/recreate the subset if you have added or removed filters like interpolate that change frame rate. The reason is that the subset (timeline) is created in post-filter frame numbers, so if you don't redo it, the length is wrong. The UI automatically does this when you exit the filter dialog, but this doesn't happen for scripts.

Woks fine !!!
I do a "VirtualDub.Subset.Delete();" after interpolate filter and got the correct frame number and A/V sync.
Thanks a lot  |
