Convert RAW YUV File to AVI with AVISynth and VirtualDubMod

Here is a straightforward way of placing a raw video file in YUV420 format into an AVI container.

• Download and Install AviSynth 2.5.8
• Download and Place the RawSource AviSynth Plug-in to AviSynth plugins directory.
• Download and Install VirtualModDub 1.5.10.3

• Now prepare a simple AviSynth script file called importYUV.avs with the following lines:

file_1 = rawsource("overbridge.yuv", 1920, 1088, "I420")
return file_1

• Run VirtualModDub
• Open the importYUV.avs as Video File.
  Now the first frame of video should appear on VirtualModDub window.
• Choose File->SaveAs to save the imported YUV file as AVI
• Choose 'Direct stream copy' as "Video mode".
• Press 'Save' Button.
• Ta-da!
