Direct Mode
in this mode encode2mpeg creates an mpeg stream, then a binary image
and finally burns
the image on the selected support (CD or DVD). You do not need to
execute all the steps, you can only create the mpeg stream or the
binary image.
A more detailed view fo the first block is showed below; mpeg2enc is
used to
create the mpeg video stream from a yuv4mpeg stream generated by
MPlayer. The audio stream can be mp1, mp2, mp3, ac3, dts or lpcm.
Different tools
can be used for this purpose: mp2enc, toolame, lame, MEncoder
(libavcodec).
Direct Mode
is the defaul mode. If you do not select a specific mpeg profile a
VCD is created. The profile options are:
-vcd
-svcd [1-2]
-dvd [1-5]
The argument of -svcd selects one the following resolutions:

Common options
The following options can be used with every profile:
-abr <n> (audio bit rate, default 384/mp1, 224/mp2, 128/mp3,
448/ac3-6ch,
192/ac3-2ch )

-n <n|p|s> (video norm)
-mp1 <mp2enc|encode|copy> (create an mp1 audio stream with the
selected
tool, default mp2enc)

selected tool, default lame)
-acopy (copy of the input audio stream)
-qmatrix <kvcd|tmpgenc|default|hi-res> (select custom
quantization matrices: this can reduces the size of the mpeg stream)
-mpegchannels <1-6> (number of channels of the audio stream, 1-6
for ac3/lpcm, 1-2 for mp1/mp2/mp3)
-normalize (normalize to the audio stream using MPlayer's audio filter
volnorm)
-volume <n> (change the amplitude of the audio stream)
-noscale (encode2mpeg automatically scales the video according to the
mpeg profile chosen, this option disable this feature)
-monochrome
-split <n> (split the resulting video in n MB chunk, defaul 800)
-nosplit (do not split the mpeg stream, defaul is to split)
-isoonly (create the mpeg stream, the binary image and the DVD iso
image without burning
it)
-imageonly (create the mpeg stream and the binary image, but do not
burn
it)
-mpegonly (create only the mpeg stream)
-streamonly (create only the elementary video and audio stream without
multiplexing them)
-cdburndevice (burn device for cdrdao, default 0,0,0)
-dvdburndevice (burn device for growisofs, default /dev/cdrecorder)
-cpu <1-8> (number of threads)
-addchapter <time,time,...|copy> (insert chapters at specified
time, or copy the chapers structure from a DVD)
-mpegfixaspect <pad|crop> (force the aspect ratio of the
source video to match the one specified with -a)
-cbr (force the use of constant bit rate video encoding)
-sync-offset <n> (adjust the audio/video synchronization)
-auto-sync-offset (adjust automatically the audio/video
synchronization; tested with TS streams)
-nowait (do not ask for a keypress before starting the burning process)
-interlaced (use it if your source video is interlaced)
-usespeed (do frame rate conversion changing the playback speed)
-res <1-7> (force one of the following resolutions)

For the vcd profile you can specify the following options:
-a <1-3> (aspect ratio, defaul 2)
-vbr <n> (video bitrate, default 1152)
-mpeg1vbr (generate an mpeg1 variable video bit rate stream. Not all
the hardware players can play such VCD)
-blank (blank a cd before burning)
-cdi <path to CD-i application files> (add CD-i compatibility)

Limitations
Direct Mode does not handle correctly video that has a
source frame rate different from the one of the final mpeg stream. This
includes source video with variable frame rate, video with non standard
frame rate (like 15 fps), and, sometimes, NTSC videos.
PAL -> NTSC
conversion is possible if you use the option -usespeed. NTSC -> PAL
conversion is possible using the option -usespeed only is the NTSC
video is not (hard) telecined.
