[QUOTE="miljbee, post: 69227, member: 16213"] if it's true, and i believe you, then mp should definitively implement that ! then, one more question has to be added to the smart zoom config : the user preferences would be simple questions : would you accept some aspect ratio modifications to display a picture ? A:Yes, B:No, C:Yes but limited if C, enter the max aspect ratio error you would accept : C% (if A, C=100%, if B, C=0%) would you accept to lose (crop) a part of the picture ? at the top and bottom of the screen ? D: Yes, E: No, F:Yes but limited if F, enter the % of the height you accept to lose : G % (if D, G=100%, if E, G=0%) at the left and right of the screen ? H: Yes, I: No, J : Yes but limited if I, enter the % of the width you accept to lose : K % (if H, K=100%, if I, K=0%) Would you allow smart expand/shrink (and a link to explain the feature) ? M:Yes - No please sort by preference order the action that mp should take to compute smart zoom : - crop - smart expand/shrink - AR change This way, we could have a 4:3 picture filling nearly a whole 16:9 screen with very little deformation. This would really be a very special MP feature. perhaps that for a tech preview, all this params could be set to some default "hardcoded" value. if they are all combined together, you don't need huge values for all of them, and this could do the trick without confusing the user about what percent of AR or picture he whish to lose. Perhaps we could start with Crop : 10% Max Smart Expand/Shrink on AR modification : 5% max the algo would select these parameters in this order. now the maths that will enable smart expand/shrink need to be defined more precisely. anyone has an idea ?
