x264 settings question

[gav1577]

Hi just a quick question are these parameters --mvrange 511
and --nal-hrd necessary to create avchd's from my bluray movies ?
do i really need them ? i understand --nal-hrd is for interlacing but not sure what --mvrange 511 is for any advice is greatly appreciated

Thanks

This is something I am interested in as well. This is what I found by myself :

mvrange
Default: 511.75

Set the maximum range of any one motion vector. The default value is the maximum specified by the h264 standard. It is not level or profile dependant, so don't touch it.

But I have absolutely no idea what HAL-NRD does. Maybe it's not wrong to keep both options in the commandline.

Thanks for the reply
So are you suggesting i can leave it out of the cmd line then if the default is 511.75 :confused:

--nal-hrd is for interlacing to make it compliant with BR specs
but isn't strictly required because you can just add it in afterward

leave them as they are.
