I want to make a script which can open a file and then save a bit of it out to a new file.
I thought I should use AddRange to do that, but this script loads the file but saves the entire file out again. What am i doing wrong?
| CODE |
VirtualDub.Open(U"C:\in.avi");
VirtualDub.audio.SetSource(0);
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(0);
VirtualDub.video.SetMode(3);
VirtualDub.video.SetSmartRendering(0);
VirtualDub.video.SetPreserveEmptyFrames(0);
VirtualDub.video.SetFrameRate2(0,0,1);
VirtualDub.video.SetIVTC(0,0,-1,0);
VirtualDub.video.SetCompression(0x7367616c,0,0,0);
VirtualDub.video.filters.Clear();
VirtualDub.audio.filters.Clear();
VirtualDub.subset.Clear;
VirtualDub.subset.AddRange(738,1200);
VirtualDub.SaveAVI(U"C:\out.avi");
VirtualDub.Close();

You want to delete VirtualDub.subset.AddRange(738,1200); and add
VirtualDub.video.SetRangeFrames(738,1200);
Where the numbers are startframe and endframe+1
In directstream mode virtualdub will start at the the nearest keyframe before the start frame though
If you wanted to start at the exact frame you'de have to do either of these
1) Recompress the beginning only
(Use fast recompress plus smart rendering, and set the video compression to the same as in the source file)
2) Recompress the entire section
-------------------
To see virtualdub's script for how it does anything, set it all up how you would do it, then queue the job
You can then open the .jobs file that's in virtualdub's directory with notepad and read it through

Ah, but "SetRangeFrames" isn't listed in the VirtualDub scripting language reference.

That's handy. Still using 1.8.5 though, don't think you could queue them there.
But thanks for your help it seems to work |

Does that not simply mean 'save 1200 frames starting at frame 738'? |

In the old versions, it's a checkbox on the save as dialog
In the new ones it's a separate entry in the file menu
Same thing though
The docs for the scripting language are kind of old so it's usually easier to read a queued job to see what goes where
Especially with using different versions, as the scripting language keeps changing
