Hi,

All I will ask may be silly but well it's better to ask to understand. So I have several questions :

1) What are exactly those x264 parameters called mbaff, wpredb and wpredp and what are they intended for ? Why aren't they listed there http://mewiki.project357.com/wiki/X264_Settings as the other parameters ? I'm sure I'm wrong on something, that's why I ask.

2) Suppose I would encode using a comand line (--parameter...), how could I use them ? I tried something like --mbaff 1 and --wpredp 2 but they seem not to be recognised by the x264.exe (I use the last x264.exe 8 bit from www.x264.nl)

3) Is it possible to hide the parameters I use to encode in order not to have them listed on stuff like MediaInfo, Avinaptic ?

Thanks in advance.

There is no particular reason in so far as I would not have any special reason to do that ; but I've seen some people doing this, that's why I'm curious to know how to do that.

Likely nobody will help with that, because asking about it suggests one is "releasing" stuff and one doesn't want others to know one's methods. It's ironic to come asking for help here and then be unwilling to share what one learns. I talk about "one" and not "you" to avoid suggesting this could be your motive. ;)

I understand your point of view ; in fact I don't understand the reason to hide parameters excepted if some "extra" parameters are used ; well I don't really know myself. And do you have any idea about the other questions 1) and 2) ? Generally speaking I thought all x264 parameters would be listed right there http://mewiki.project357.com/wiki/X264_Settings but it seems not or I'm simply wrong. Are they another parameters not listed there then ?

MBAFF is the interlaced mode x264 uses. Activated by parameters --tff or --bff respectively.
Wpredp can be controlled by --weightp, wpredb by --no-weightb.
