Stream
Type: This is what type of video you want to encode
MPEG-1 or MPEG-2.
Size: The size in pixels of the file you are going
to encode the standard of VCD is 352x240 (352 horizontal
lines by 240 vertical lines) and SVCD is 480x480 (480
horizontal lines by 480 vertical lines)for NTSC and
for a PAL VCD its 352x288 and for SVCD its 480x576.
Aspect Ratio: This is the aspect ratio that the
final product will come out as.
1:1
VGA: This would be the correct aspect ratio if
you plan to watch your video on
your computer.
4:3 525 line NTSC: This would be the ratio
you would use if you want to format your video to
play on a NTSC TV (US and Japan systems).
4:3 625 line PAL: This would be the ratio you
would use if you want to format your video to play
on a PAL TV (Everywhere else in the world).
16:9 line 525 NTSC: This would be the aspect
ratio you would use when you want to have your video
fit properly on a 16:9 NTSC television or to have
you standalone player fix the aspect ratio for you.
16:9 line 525 PAL : This would be the aspect
ratio you would use when you want to have your video
fit properly on a 16:9 PAL television or to have you
standalone player fix the aspect ratio for you.
Frame
Rate: As far as I know when movie is played back
the decoder doubles the frame rate, so 25fps will
be 50fps when played back. The only ones I really
see anyone using are...
23.976: This is used mainly for FILM and adding
3:2 dropdown conversion which I will go into later.
24: Pretty much the same as 23.976
25: This is the PAL 50Hz standard that is used
all over Europe and other cricket playing countries.
29.976: This is the US and Japan 60Hz standard,
I'm not sure what other countries use this.
Rate
control Mode: This would be the initial setting
that determines what type of bitrate you would use.
Constant
Bit Rate(CBR): This means that your bitrate will
have a fixed setting, and during high motion scenes,
due to being fixed, block noise may occur. It is encoded
by TMPGEnc reading a few frames and then encoding
them. More or less it thinks about what it is going
to do before it does it.
2pass Variable Bitrate(VBR): This means that
your bitrate has an minimum, maximum, and average
bitrate. On this one you can set the average to a
fixed setting and have it either raise to the maximum
you set during high motion scenes or fall to the minimum
you set when there is little motion. This setting
is good for figuring out the size of the file that
is being outputted and to have it reach higher bitrates
yet still maintaining a lower file size. under the
settings of this setting is where
you would put in everything you need to. There is
also a setting, "Enable padding When falling
below the minimum bitrate", if checked. forces
the rate of the movie not to fall under the minimum
bitrate you entered. Also this setting will go over
the whole movie first then at 50% it will start to
encode it, and this takes time...Allot of time! Why
would anyone do this you ask. Well I do this because
I know approx. what the file size will be and I feel
that I will get the most out of my movie. This is
for MPEG-2.
Manual VBR: Is a fixed bitrate that variants
with each scene this setting is used with the "Force
picture type setting" under the GOP Structure
tab to be explained later. So it has a constant bit
rate that stays the same until the scene changes and
TMPGEnc will figure this out when you do the Force
picture type thing. Under it settings you can set
the maximum, minimum bitrate, and the padding setting.
the p and b picture spoilage when partial CQ normally
does not need to be changed. It sets how much you
don't care about each picture set. ( Will go into
I, P, and B picture in a later tab)
Automatic VBR: This is pretty much the same
as above but it does it figures out what to set its
bitrate to on its own. It also has a maximum, minimum
bitrate, and padding feature. but also lets you set
the quality of your encode, the higher the number
the better quality but bigger file size.
Constant Quality(CQ): I dont really know to
much about this one but from what I know it is like
Automatic VBR, it has the same settings and does the
same thing as above but you can set the p and b spoilage
which doesn't really need to be changed. Funny...
If anyone can elaborate that would be cool.
Real-time CBR: or Real-time Constant bitrate..
This is the evil twin to CBR instead of thinking about
his actions first like CBR he does his thing "on
the fly", meaning it does its thing without reading
ahead. Quality can degrade over time with this one
and I recommend staying away from this one.
Real-time CQ: And again this does everything
that CQ does just "on the fly", picture
still degrades and I dont recommend this one either.
Bitrate:
This only opens for the CBR setting and this is where
you put the bitrate for the CBR family.
VBV Buffer Size: This sets the decoders buffer
size to use when decoding the movie. When loading
templates it will set this to the best setting, but
just in case MPEG-1 uses a value of 40 and MPEG-2
Uses 112.
Profile&Level: this has to do with the level
of your decoder most DVD players are MP@ML so it would
be best to leave this one alone.
Video Format: Set this to the what your video
source is.
Encode Mode: this will encode movies in different
ways depending on what you set.
Non-Interlace: It encodes your movie so that
it does not have interlaced pictures... A interlace
picture is a picture that has 2 picture per frame
and if you remember back when I was talking about
Frames Per Second I said it doubled itself, well frame
A is half of the picture starting with the top line
and the skipping the next then shows the one after
that. The B half of the frame puts in what frame A
missed, so when the frame rate is doubled you get
the full picture and also your 60Hz of NTSC or 50Hz
for PAL. Ok now this encoding method doesn't do this
it puts frame A and B together to make frame A then
doubles it to get a exact copy for frame B. Using
this makes a source progressive.
Interlace: Ok this one does what I said above
It encodes a 29.976 non interlaced movie to shows
half the frame in frame A and half in frame B. This
is for converting to 29.976FPS from a 23.976FPS movie
with the help of 3:2 pulldown under the advanced tab.
3:2
pulldown when playback: This is used when you
have a FILM source movie (23.976fps) to leave it 23.976
but have your decoder play it back at 29.976fps. (works
great for ripping DVDs). when 3:2 pulldown is used
it does this.. It takes four sequential video frames
(A, B, C, D) from the FILM and are drawn on the video
display as A1, A2, B1, B2, C1, C2, D1, D2, where the
1 or 2 represents the field number within the frame
Inverse 3:2 pulldown: I have no clue never
had to use it. I would guess and say that it will
undo 3:2 pulldown.
YUV
format: This has to do with color loss, its best
to leave this one alone.
DC component precession: The higher the number
the smoother the movie. I always set it to 10.
Motion search precision: Motion
search precision adjusts how much the encoder searches
for motion between different frames. This means it
looks at a block in a frame and then looks at the
next frame for the same (or similar, depending on
other settings) block somewhere else in the picture.
If a similarity is found, information on the direction
and how much the mpeg block moved between the 2 frames
is put into the mpeg stream, so that the block is
used
in a different place in frame 2. By doing this the
same thing isn't encoded twice. This means that less
bits are used when things are repeated. then bits
can go to other things like encoding the block better
in the 1st frame.
Setting the motion search precision to the highest
quality (slowest) setting will make the encoder search
really hard for repetition between frames. This makes
the picture a lot better when things are moving.
If you encode a video with only small amounts of movement,
you can sometimes get away with lower settings to
save time, but even in low motion pictures, different
parts of the image might be the
same, so I always use the highest setting to give
the best picture.
Professional DVD authoring hardware uses extremely
sophisticated methods to search for motion, and that's
what makes them so expensive, but so high quality.

Video
source type: This would be set to whatever your
source video is either FILM(non-interlace) or NTSC(interlace)
Filed order: This tells TMPGEnc what field comes
first from the NTSC(interlaced) source field A or
B. the only way to tell is to encode a small portion
and if it is jumpy flip the field order.
Source aspect ratio: This sets the source ratio.
1:1 VGA: Is used when your source was encoded
for your computer(streaming video and things of that
nature)
4:3 525 line (NTSC): Is used when your source
was encoded to be played on a TV.
4:3 525 line (NTSC 704x480): what I know about
this one is that it is pretty much the same as the
above 4:3 but it has the correct aspect ratio of your
TV. I'm guessing this would be for a video capture
or something to that effect.
4:3 625 line (PAL): This would be used for
sources that are PAL and formatted to fit TV.
16:9 525 line (NTSC): This probably would be
used for previous conversions from FILM to NTSC left
in 16:9 and not letterboxed into 4:3 (letterboxed
is when you see the black bars on the top and bottom
of a 16:9 source to make it 4:3)
16:9 625 line (PAL): Same as above one but
for PAL.
4:3 display: Is used for the rare DVD that
is actually NTSC and 4:3.
16:9 display: is used for DVD that is formatted
16:9.
2.11:1 display: ???
Video
arrange method: This is how the video is arranged
in the frame.
Center: This centers the video on the frame
not preserving aspect ratio.
Center(keep aspect ratio): Centers the video
on the frame preserving aspect ratio.
Center (custom size): Centers the video on
the frame and keeps the video to the size you set.
this helps if you want to keep the anamorphic ratio
to fit in 16:9 or 4:3.
Full Screen: Not sure will update.
Full Screen(keep aspect ratio): Not sure will
update.
Full Screen(keep aspect ratio 2): Not sure
will update.
No margin: Basicaly turns 16:9 into 4:3 by
cutting off the edges of the video.
Filters: These are the different filters you
can use when encoding.
Source Range: Lets you set the source length by
setting what frames to encode between (10 - 6000)
Inverse Telecine: Will allow you to undo 29.976
or 30fps from a interlaced source. If you set your
frame rate you want to 23.976 this will turn non-interlaced
29.976 or 30fps into FILM.It will also allow you to
deinterlace it here
Ghost reduction: Remember when you put in old
camcorder or VCR tapes you see a double image of something
this will take that out by moving the position, strength
and blur sliders. I've never had to use this so I
really dont know how to really use it.
Noise reduction: This can be used to take out the
grainy look of old VCR tapes. Beware it takes a long
time.
Sharpen edge: Can be used to either sharpen
or blur the edge of graphics you might ad in like
a End Of Disk 1 or something. It also can take out
blocks made by Divix movies.
Basic and Custom color correction: In these
2 you can change the color, brightness and contrast
Deinterlace: This helps to take out the interlace
effects that sometimes wont come out when converting
DVDs
Clip Frame: You can turn 4:3 Into the appearance
of being 16:9 with the look of letterboxing by adding
top and bottom masks. and without the masks you can
actually turn it into 16:9 if you set 16:9 as your
aspect ratio for output. You'll have to mess with
the settings in order to get them to look like it
is 16:9.
3:2 pulldown: This is what you use with the
interlace setting under the video tab to make your
FILM NTSC for VCDs(using the 3:2 pulldown when playback
is still the best way to do it for SVCD and DVD).
Do not frame rate conversion: Despite the bad
English, I don't really know what this is used for
besides not letting it change frame rate. I see no
need to ever use this.
Audio
effect: This is where you
can adjust the volume and normalize the audio, also
you can ad in a fade in and out.
Noise
reduction: Noise reduction is useful when encoding
from an MPEG source. MPEG adds noise to the picture
around sharp edges. A setting of "[Still Picture:2]
[Range:1] [Time Axis:2]" is helpful in
removing such noise, but it can slightly reduce detail
in the picture without removing all the noise. - mikk
The
rest of the tabs are pretty much easy to figure out
so I'll leave you to that. Have fun and great encoding.
