Anamorphic Strict, Loose or Custom (untouched w/ no cropping)? I've been using Anamorphic = Loose and Modulus = 16. I've read this allows the m4v to be properly displayed on various sized screens. Yet the Source and Output sizes differ. Now I've read using "Custom" and manually entering the height/width to "Source" is best (ex Source=720x480, Output=720x480). Using Loose, a 720x480 source would encode to 853x480 with cropping.Using aTV 2 (50" Pioneer Elite Kuru), sometimes watch movies on my Mac Pro w/ dual 24" LED LCD's (very rare if I watch on my iPad, I'll simply make a compatible copy). Grain and Sharpness: Deblocking and Psychovisual settings (sharpness strength/grain). Made various m4v's of the same DVD using various settings: Deblocking: -1,-1, 1,1, or 0,0 (default) w/ various psy-rd and trellis settings Differences are extremely subtle, but apparent (esp in dark/white). My rips are SD DVDs (no animations) and a few BD's. I'm guessing leaving deblocking at default and tuning Psychovisual may be best (read Psy-rd at max and Psy Trellis around 0.20 is recommended)? Any suggestions would be hugely welcomed. This is the last encoding tweak I need to settle. Thanks!
