First, check that post-processing is turned off for the current session in the “Video > Post processing …” menu. You can also turn it off definitely in the “Tools > Preferences” menu, in the Video tab. Next, if you added a resize filter, set it to resize using the Lanczos3 method instead of Bilinear or Bicubic. Lanczos3 is the most accurate resizer, or so to say. However, resizing kills details by nature, there’s no way around it. Not resizing might be a better option sharpness-wise depending on what you’re trying to do. Finally, tweak the encoder settings. Discussing the best quality settings for each encoder isn’t the FAQ’s goal. Encoder-specific guidelines are available in the avidemux forum or on the web.
