converting a 59.940 FPS avi into a 23.976 FPS one
by Tetsuo Yokozuka 06 Feb '05

06 Feb '05

Hello, I have a 720p (yes, *progressive*) MPEG2 avi file at 59.940 FPS ripped from HDTV, and I would like to convert it into an XviD avi file at 23.976 FPS. I have read the man page, as well as the HTML doc, but I'm confused. I can't find a way to do that without the video getting choppy. While I'm at it, does it matter that the resulting FPS rate be exactly 23.976, or could I convert the video to exactly 24 or 25 FPS just as well?

multi language sub files
by Phil Ehrens 03 Feb '05

03 Feb '05

Hi folks. I find that whereas '-slang en' works fine in mplayer, when I attempt to use '-slang en' in mencoder with a .sub file where subtitle stream 0 is not the english set, I always get subtitle stream 0... which is generally Chinese... which for me is worse than nothing. What am I missing?

Hi, Is it possible to use mencoder to pull either a single frame or maybe a small number of frames out of a video file and store it is a a jpeg or something similar? Cheers, Aaron

Using a custom quant matrix w/ xvid (How to?)
by Lee Morgan 29 Jan '05

29 Jan '05

Hi, I'm trying to use a custom quant matrix. The problem I'm having is that every time I try to run xvid with it xvid returns a "Error reading the matrix file /Users/lee/Jawor_2CD_Matrix.xcm" I'm using the following options quant_intra_matrix=/Users/lee/Jawor_2CD_Matrix.xcm quant_inter_matrix=/Users/lee/Jawor_2CD_Matrix.xcm It runs fine without these options (heck it even runs with them, but gives the error reading warning). Any idea how I can fix this? Also, what's the "recommend" CQM for medium to high (1000 - 1800) bitrates to keep quality high (even in higher frequencies - ie white outs). And does anyone have a link to the EQM v3 HR quant matrix for xvid? Thanks, Lee

DVD ripping for iriver H300 out-of-sync
by James Lee 28 Jan '05

28 Jan '05

Hey, I am writing a program (http://sourceforge.net/projects/iriverter) to convert videos for the iriver H300 series mp3 player. It has very strict specifications for playback. Video: XviD 220x176 <=10 fps <=500 kbps <=60 minutes Audio: mp3 128 kbps 44100 hz The basic skeleton command that I'm using to convert videos on file (not DVD) is as follows: mencoder "/home/jlee/Video/Family Guy/Season 1/101 - Death Has A Shadow.avi" -o "/home/jlee/Desktop/test.avi" -ffourcc XVID -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=450 -oac mp3lame -lameopts mode=2:cbr:br=128 -vf scale=220:165,expand=220:176 -af resample=44100 -srate 44100 -ofps 10 I get excellent AV sync on the iriver with this command no matter what file I pass to it, but when I adapt it for DVDs, the sound is behind anywhere from .5 to 1 second on the iriver (it sounds in sync on the computer). The command I use for DVDs is like: mencoder dvd://1 -o /home/jlee/Desktop/test.avi -ffourcc XVID -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=450 -oac mp3lame -lameopts mode=2:cbr:br=128 -vf filmdint=io=30:10,scale=220:123,expand=220:176 -af resample=44100 -srate 44100 -ofps 10 -dvd-device /dev/dvd -alang en Then test.avi is split into pieces less than an hour long. mencoder /home/jlee/Desktop/test.avi -o /home/jlee/Desktop/test.part1.h300.avi -ovc copy -oac copy -ss 0 -endpos 2863 Now the only differences between the DVD conversion and regular file conversion is the filmdint filter the splitting. Without the filmdint filter the video is terribly choppy. Can anyone spot anything that might cause this sync problem. I really appreciate the help, James Lee jlee23(a)umbc.edu

Sony DSC-M1 files
by Rick Richardson 25 Jan '05

25 Jan '05

I have videos produced by the Sony DSC-M1 video camera. They are mpeg-4, as shown below. mplayer works OK on these files. But when I play them on a Philips DVP642 player only the video plays. I would like to re-encode them so that they use something different for the audio. Can somebody help???

Could anyone tell me why I would want to encode duplicate frames, wouldn't using -noencodedups be better instead of wasting disk space? - lee

reencoding from a mkv with subtitles
by Marc Cousin 22 Jan '05

22 Jan '05

Hi, I'm trying to convert a mkv with subtitles, to a simple xvid avi, with the subtitles directly displayed in the movie. To do this, I've tried : mencoder -slang fre movie.mkv -oac mp3lame -lameopts cbr:br=128 -ovc xvid -xvidencopts vhq=1:chroma_me:hq_ac:bitrate=1500 -o movie.avi The problem is that the subtitles aren't correctly displayed (bottom of it is displayed randomly on the screen, and distorted), on the encoded avi. Of course, the movie plays ok with mplayer and subtitles ... Here is the output from mencoder about the mkv : [mkv] Found the head... [mkv] + a segment... [mkv] /---- [ parsing seek head ] --------- [mkv] /---- [ parsing seek head ] --------- [mkv] \---- [ parsing seek head ] --------- [mkv] /---- [ parsing cues ] ----------- [mkv] \---- [ parsing cues ] ----------- [mkv] \---- [ parsing seek head ] --------- [mkv] |+ segment information...

But then if I'm right why does mplayer manage to display them correctly and not mencoder ? Cheers Marc Cousin -- BOFH Excuse #151: Some one needed the powerstrip, so they pulled the switch plug.

encoding quality problem
by simone marchi 22 Jan '05

22 Jan '05

Dear all, I'm trying to encode via lavc a mpeg1 stream. The problem is this: If I play (with mplayer) the mpeg1 stream with spp filter option activated the quality of video is better. If I encode (with mencoder) that mpeg1 stream (via lavc) with spp filter (or pp filter) the quality of encoded divx video is like the original (i.e. poor). Could anyone help me? ps: other filters like "scale" works fine. thank you! ciao simone. ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

Help building xvid & mencoder
by Lee Morgan 22 Jan '05

22 Jan '05

Can someone please help me with building mencoder with xvid support? I'm running Mac OS X on a PowerBook, and I'm trying with the newest builds (1.1.0b1 & 1.0pre6). Please note that I'm not really unix savvy (just know the basics like configure, make, make install). Thanks, Lee P.S. To the people who are also subscribed to the xvid list sorry for the cross post, I didn't know which list this would pertain more to.
