The MeGUI AviSynth script creator is used to create the AVS file which will supply the data to the video encoder to be encoded. It provides a standardised way to load any type of video into one program, as well as process it in various ways. The AVS creator provides a frontend to create the AVS script for you.

Basic input and processing.

  • Video Input: Load the video source you want to use as input.
  • Re-open original video player: Reopen MeGUI's video preview window.
  • Video DAR: Set the input DAR. MeGUI mostly detects this correctly.
  • Clever (TM) Anamorphic Encoding: Checking this box will enable anamorphic encoding. There are three methods to encode anamorphic video with MeGUI:
  • Resize to mod16: Video is cropped as requested, then resized to mod16 dimensions.
  • Overcrop to achieve mod16: Video is cropped by at least the requested numbers. Extra cropping is done so the final video is mod16.
  • Encode non mod16: Video is cropped as requested, then resized as requested.
  • AVS Profile: You can load an Avisynth profile here. AVS profiles are templates used when by the AVS Script Creator. Their use should be reasonably self-explanatory if you know enough to touch them.
  • Crop: 'Cut' the sides off the input video, in case there are black borders. MeGUI will graphically the cropping if the video preview window has not been updated since it was opened.
  • Resize: Resize the video. Resizing is only allowed to multiples of 16, and when reducing the resolution. See these two pages for information on why these restrictions exist.

Deinterlacing and other filtering.

  • Deinterlacing: Choose what deinterlacing (if any) should be applied.
  • If you know the video type already, set the 'Source Type' and choose appropriate deinterlacing.
  • If you don't know the video type, click 'Analyse' (make sure 'source is anime' is ticked if appropriate). MeGUI will make a (virtually always) accurate guess as to the source type and suggest filtering.
  • Resize Filter: Choose the resizer algorithm. Generally, spline36 is a good choice.
  • Noise Filter: The noise filter adds one of four predefined noise reducing scripts to the AVS file. The noise reductions go all the way from undot() to Convolution3D("movielq").
  • MPEG2 Deblocking: Should only be enabled for very blocky MPEG-2 sources, which generally means not on DVDs, such as the following:
  • Colour Correction: Automatically added with .d2v sources. Colour correction for DVDs and other MPEG2 files ensures the video has the right colours.
  • Framerate: Required only if MeGUI cannot auto-detect it.
  • Vertical Flip

The options down the bottom of every page:

  • On save close and load to be encoded: When this is checked, immediately after saving the AVS creator will be closed and the AVS loaded into MeGUI ready for you to set up video encoding options.
  • Preview: Clicking this will refresh the video preview window. Be aware this causes a problem when cropping, as detailed above.
  • Save: Saves the AVS.
