Subtitle position, hardcode, using MEncoder or VLC command line...

[zehd]

Hi to all, and thanks in advance...

I'm writing an on-the-fly transcode helper for a PVR app that takes AVIs and transcodes to MPGs for viewing on the Hauppauge MediaMVP...

I have had great success using FFmpeg, MEncoder and VLC as command line driven transcoders.

I'm trying to include support for Subtitles, I'm starting the quest with srt files...

I've been able to get SRT files to display during a transcode using MEncoder:

"C:\Program Files\mplayer\mencoder.exe" -oac lavc -ovc lavc -of mpeg -mpegopts format=dvd:tsaf -vf lavcdeint,scale=588:324,expand=-52:-156:16:62:1,eq2=1.0:1.10:0.10:0.90:0.95:1.0:1.0:1.00 -srate 44100 -af lavcresample=44100,volume=0.0 -lavcopts vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=4000:vbitrate=4000:keyint=18:acodec=mp2:abitrate=224:aspect=4/3 -ofps 29.97002997003 -sub "C:\TV\Video\Stargate.SG-1-S10E14-The.Shroud.srt" -font "C:\WINDOWS\fonts\arial.ttf" -subfont-text-scale 2.5  -o "C:\TV\Override\Stargate.SG-1-S10E14-The.Shroud.mpg" "C:\TV\Video\Stargate.SG-1-S10E14-The.Shroud.avi"

But I can't adjust the position of the subtitle. I'd like to have it vertically adjustable, to compensate for overscan when displaying on old televisions...

I'm also not able to have subtitles display with either VLC or FFmpeg... Could someone give me a definitive answer as to the possibility, or even eventual availability of these features.


Thanks
Frank

I tried to bold the example. There is a typo. The code should read as follows...

"C:\Program Files\mplayer\mencoder.exe" -oac lavc -ovc lavc -of mpeg -mpegopts format=dvd:tsaf -vf lavcdeint,scale=588:324,expand=-52:-156:16:62:1,eq2=1.0:1.10:0.10:0.90:0.95:1.0:1.0:1.00 -srate 44100 -af lavcresample=44100,volume=0.0 -lavcopts vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=4000:vbitrate=4000:keyint=18:acodec=mp2:abitrate=224:aspect=4/3 -ofps 29.97002997003 -sub "C:\TV\Video\Stargate.SG-1-S10E14-The.Shroud.srt" -font "C:\WINDOWS\fonts\arial.ttf" -subfont-text-scale 2.5  -o "C:\TV\Override\Stargate.SG-1-S10E14-The.Shroud.mpg" "C:\TV\Video\Stargate.SG-1-S10E14-The.Shroud.avi"

When all else fails... read the manual.

-subpos <0-100> (useful with -vf expand)


Specify the position of subtitles on the screen. The value is the vertical position of the subtitle in % of the screen height.

I appreciate you not using the obligatory 4 letter acronym... But, I have read that, several times, and tried and tried. It seizes at the command line...

It says that the line doesn't work.

Edit: I was mistaken. I was using -sup-pos, which is a typo of course. Thank you for your help with MEncoder.

Would you happen to know the syntax for VLC, pre 0.90

I notice you're specifying Arial.

Even if you use standard Windows fonts, Verdana or Trebuchet are better.
See http://screenfont.ca/fonts/today/interim/ for probably more than you want to know about subtitling fonts.

Anyway, try a few alternatives out before unleashing your files on the world.

That's great advice...thanks
