MeGUI and zones

Two questions... First, I have problems saving profiles with zones set. Not sure if its a bug or not. If I take a profile, and add a zone, when I click OK to exit the configuration, I get the pop-up saying that I've changed the configuration, and asking if I want to update the profile... If I update the profile, the zone stays until I close and re-open MeGUI, then its gone. Adding the zone in the "Custom Commandline Options" seems more reliable. Second, this one is more of a x264 question: When using zones, you have two choices weight (bitrate), or Quantizer. The Quantizer option is "...frame.q35" Is that Constant Quanitizer or Constant Quality? ( -qp 35 or -crf 35 ) I'm guessing that its -qp, but since the switch is different, its a little ambiguous.

megui doesn't save zones. Why? Because zones are movie dependant. So suppose you defined your zones and accidentally add it to a profile (it used to be that profiles were automatically updated which greatly increased the chance of this involuntarily happening), then the next time you start up, you select that profile again, forgetting that you had zones set.. and then you wonder why your movie didn't come out the way you wanted it. If you really want this, make your own custom build and deactivate the zone clearing before saving the profile. iirc the quantizer option for credits always means constant quantizer.

Doh! I just realized I've been using the zones wrong... I've been using them to put a constant quantizer on the end credits. But MeGUI can do that automatically, can't it? When you set the "Credits" position in the video preview, I'm guessing that uses the "Credits Quantizer" setting to apply a zone to that part of the video. It doesn't show in the command line window in the Video Confif window, though.

Zones in 2pass

Do zones work in 2pass or Bitrate mode? A friend of mine told me that zones work in crf mode only. Anyhow, I encode a video with 2pass and apply zones for a certain duration. The filesize remains the same as if it was encoded at a normal bitrate even though I increased the bitrate significantly when I applied zones. So does that mean zones didn't get applied??? But when I saw the encoded settings of the resulted video with "mediainfo", zones were written there. What did actually happen???
