MeGUI Metadata

I've noticed that MeGUI (x264 component) does not write GOP meta data to the resulting encoded file. See attached.

The left hand mediainfo does not show GOP metadata...that is, no GOP:M=3,N=29. The left hand side encode was done with MeGUI and the right hand side with Adobe Media Encoder (others behave same way). I like to see such info written. Is there anything I need to check as an option in MeGUI to add the GOP metadata in?

thanks

Your attachment is pending approval, but I'm assuming you are referring to what mediainfo says - Megui doesn't write it, nor does the encoder x264

It will appear in mediainfo if you disable adaptive b-frame decision (--b-adapt 0) and scenecut (--no-scenecut) . Which is basically a bad idea most of the time and reduces efficiency. The GOP size and makeup will be fixed, static, and not adapt according to the content (encoder won't adapt in terms of b-frame placement or insert I frames for big changes)
