View Full Version : Need a little help with mencoder script

I encode a lot of stuff thats already deinterlaced during the capture, but do have films off my firewire camera thats interlaced and trying to remove that.
I would of thought googling for mencoder deinterlace would return just what i am after but it seems to of sent me on a wild goose chase. There seems to be many different arguments you can use to deinterlace, but all i have tried either error of fail.
Here's my latest
mencoder "/mnt/win_f/Championship.avi" -oac copy -vop scale=512:432 -vf pp -ovc lavc -lavcopts vcodec=mpeg4:trell:v4mv:vhq:vqscale=7 -o ~/j/2004/mpeg4/Championship.avi
Here i get a 720x576 film thats interlaced still :confused:
HELP! :D

Which option in there did you think was supposed to deinterlace? I don't see one.
The available deinterlacers are:
-vf lavcdeint
-vf kerndeint
-vf filmdint
-vf pp=lb
-vf pp=li
-vf pp=ci
-vf pp=md
-vf pp=fd
Some are better than others, but I rarely deal with interlaced content so I can't tell you which those are.

Ok the last thing i read late last night, fallin asleep was
-vf pp
I guess that was wrong. I couldnt find the list of options in the mencoder man either :confused:
Thanx for that list. I will have a play.
I would want the deinterlacing to be performed BEFORE the resizing. How is this possible?? Order of the arguments ?? A specific argument of its own ??
thanx

Yes, filters are applied in the order you specify them. e.g.
-vf pp=md,scale=512:432
('-vop' is obsolete. And you can only use one copy of the '-vf' option; multiple filters must be separated by commas.)
to see the list of suboptions for '-vf pp', look at 'mplayer -pphelp'

OIC vop is out ??
a number of arguments for deinterlacing i found returned the error that they were depreciated
ok so hows this then
mencoder "/mnt/win_f/Championship.avi" -oac copy -vf pp=md,scale=512:432 -ovc lavc -lavcopts vcodec=mpeg4:trell:v4mv:vhq:vqscale=7 -o ~/j/2004/mpeg4/Championship.avi
this should work right ???

Just out of curiosity, which version of mencoder are you using?
You can always try encoding a small sample to see if things look the way you want, e.g. by using a combination of the "-ss" and "--endpos" options

MEncoder 1.0pre5-3.4.1 (C) 2000-2004 MPlayer Team
That last command seemed to work a treat. I used pp=ci, as i came across that more in ym searches and use BiCubic in VirtualDub in Windows.
I would like to try all the different one', but i also would like there to be 40 hours in a day ;)

It doesn't take long to try them. You don't have to encode; the same filters work in mplayer.
