According to the wiki, it's not possible to change these 2 parameters on a per-zone basis. In theory it should make sense at least if both beginning and end of the zone is at a scene change, since it can modify (with psy-rd, that is already customizable) the way x264 decide how to quantize the macroblocks of the frame (in better or worst way). Am I right? Is it possible to allows this customization? Thanks.

Seconded... I'm not one to be ungrateful for open source (free!) software, but AQ-Strength is one of the switches I find to have the biggest impact on image quality. I'd certainly be interested in tweaking it on a shot by shot basis.

It's possible, but it requires a different architecture from the normal zones, because AQ is calculated in lookahead, not the main encode.
