This is a port of Yadif (yet another deinterlacing filter) for using with Sony Vegas.

Installation

Please copy included

• Yadif Deinterlace.ofx.bundle
  
  to
  
  
• C:\Program Files\Sony\Vegas Pro 10.0\OFX Video Plug-Ins

If Sony Vegas installed to a different directory, then please copy it accordingly to the inner "OFX Video Plug-Ins" folder of Sony Vegas.

Usage

1. For the target clip, in the properties set 'Progressive', even though it is interlaced, so that Vegas does not deinterlace it.
   Alternatively set Deinterlace method in the project properties to 'None'.
2. Insert Yadif Deinterlace as Media FX (note, NOT video FX or track FX, but Media FX) on the clip.
3. Setup Yadif Deinterlace parameters to select field order and rendering parity
   (parity defines which field will be left unchanged and which interpolated).

Step #3 is optional, since in most of cases default plugin parameters are suitable.

Please note, that due to restrictions of how Vegas works, this plugin cannot be used to increase frame rate or to create a smooth slow-motion sequence from interlaced video.

Alternative way

If you want to insert it to all interlaced media in the Vegas project at once, then run the script 'Apply Yadif to All Media.cs', which is enclosed in the archive.

To run the script, select Tools -> Scripting -> Run Script... in the Vegas menu and navigate to the script file.

If you insert more media to the project, just re-run the script. It will not touch already processed files.

The script does automatically the same procedure as described above.
