Automated Cutting and Transcoding Guide Using Mencoder

I am pretty sure trellis and mpeg quant will not work on Phillips DVP642.

That is correct.

This mencoder script works nicely for telecined NTSC:

-oac mp3lame -lameopts mode=2:cbr:br=192 -sws 9 -vf yuvcsp,pullup,softskip,scale=720:480::0:9,crop=672:448:24:16,expand=704:480:16:16 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=%Bitrate%:vhq:vmax_b_frames=1:nr=100cplx_mask=0.03 -ffourcc DIVX -ofps 24000/1001

That is correct.

Thanks for the info guys. I've attached an updated script with trellis and mpeg quant removed.

Hi Dano,

Are you suggesting this script for transcoding for hardware divx players?

[jam_zhou]

I can confirm that this will work on the Phillips player...you should be able to easily modify it to two pass:

%SOURCE% -oac mp3lame -lameopts mode=2:cbr:br=%AUDIOBITRATE% -vf scale=%RESOLUTION%,pp=hb/vb/dr -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=%VIDEOBITRATE% -ffourcc DIVX -o %DEST%

Yes, I use this script for my Phillips Divx player. I cap at 12 Mbps CBR and 384kb for audio. I have already modified the script for higher quality but the speed decrease is twofold (I am at work now and can post the script later). I have been having a hard time balancing the PVR-250 noise reduction filters and the noise reduction of mencoder (I gave up on hqdn3d due to smearing) to get them just right for all TV channels. I am probaly going to switch my PVR-250 with a PVR-150 which currently resides in my HTPC/MediaMVP setup because of superior image quality.

This is what I am currently using but, I am still not satisfied with the noise reduction. FltDnrSpatFltLevel=0 and FltDnrTempFltLevel=4.

mencoder.exe %1 -oac mp3lame -lameopts mode=2:cbr:br=%AUDIOBITRATE% -sws 9 -vf yuvcsp,pullup,softskip,scale=720:480::0:9,crop=672:448:24:16,expand=704:480:16:16 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=%Bitrate%:mbd=2:mv0:precmp=2:cmp=2:subcmp=2:predia=2:dia=2:preme=2:v4mv:last_pred=2:vqcomp=0.6:vmax_b_frames=1:nr=200:scplx_mask=0.03 -ffourcc DIVX -ofps 24000/1001 -o "%~dpn1.avi"

What is the difference, functionality-wise, between this mencoder script and that of jam_zhou found here: http://forums.nextpvr.com/showthread.php?t=10685

Other than that they seem to do all the same things, yes?

Sorry, I'm not familiar with jam_zhou's vbs script. Try both and find out.
