Settings for the Advanced Input Section of the DVD Ripper window

Output frame rate:
Frame rate of the output video file. 25 (PAL) or 23.97, 29.97 (NTSC).
Warning: this value is not automatically set. If you choose a different frame rate from the actual input rate, a conversion will be performed to obtain the selected output frame rate; but you should avoid converting NTSC to PAL, or PAL to NTSC .
Default is : 29.97 (NTSC)

Detect 24Fps:
Detect automatically for a 24Hz progressive NTSC movie.
Default is : Yes

Force 24Fps:
Force the movie source to be recognized as a 24Hz progressive NTSC.
This flag is in effect only if í«detect 24fpsí» is also checked. (Use this option if you think that the 24Hz detection is not working).
Default is : No

Subtitle Offset:
Vertical offset of the subtitle expressed in pixels.
This value is automatically adjusted if the subtitle extends beyond the screen.
Default is : 0

Original color:
Preserves original color of the IFO file.
Uncheck it if your subtitle is too dim.
Default is : Yes

DeMacroVision:
Remove macro vision protection from the movie.
Default is : Yes

Key Search:
Mode for CSS key search (the mode 0 works fine in 99% of cases).
0 - Search a key one time when starting the ripping process
1 - Search a new key at each VOB-ID
2 - Search a new key at each CELL-ID
3 - Search a new key at each VOB/CELL-ID combination
4 - Disabled
Default is : 0

Audio 48KHz to 44.1 KHz:
48KHz downsampling mode.
0 : Normal mode (fastest)
1 : High quality (slower)
2 : Export AC3
     Exports the source AC3 to an AC3 audio file along with the exported AVI file. See the í░output settingsí▒ Help File for details.
3 : 44.1KHz (no conversion)
     Select this option when you do not want to make an audio rate conversion (when you already have a 44.1KHz source stream and want a 44.1KHz output rate).
4 : 48.0KHz (no conversion)
     Same purpose as choice 3 except refers to 48.0KHz.
Default is : Normal mode

Volume:
Gain of the audio output.
No normalization is performed; so, if the value is set too high, clipping of the audio signal may occur. A value of 1 can not generate distortion (crackling), but the output sound may be very low. The default value produces a good volume for most DVDs.

You can make a few clips of the movie where you know the volume is high, and adjust this value in order to get a satisfactory volume. You can also use the sound normalizer tool (in Tools menu) to find an optimum volume.
Default is : 3

Dolby Surround:
Enables Dolby Surround sound downmixing.
Preserves a better sound in 5.1 FX stereo mode
Default is: Enabled

iDCT:
Inverse Discrete Cosine Transform routines (also includes motion compensation).
MMX is fast and suitable for most CPUs. FPU selection always gives the best quality.
Default is : Auto detected

Overlap:
When the output volume size has been reached, the Overlap value is used to determine the length in seconds of the overlapping segment portion that successively created volumes will contain. (This setting has no effect in custom chapter splitting). For example: If Overlap=10, and the first volume created ends at a time of 1:10:25, then the next volume created will start at the time 1:10:15
Default is : 0 sec

Audio Video Synchronization:
Re-synchronize video and audio periodically. (not always necessary).
Default is : No

Save your DVD drive:
Create a temporary buffer to avoid having the DVD drive being switched on/off too frequently.
If you use a RAM buffer you can also disable virtual memory to obtain an even faster ripping speed. The file will be written in your Windows temporary directory (TMP environment variable).
Default is : 10MB, Location: RAM

Luminance filter:
Adjusts the brightness level.
The Y plane is the luminance plane (in YUV format). Applies the formula: Gain*Y + Offset on the Y plane. Gain is an 8.8 fixed point value. (0 = 0.0 ; 128 = 1.0 ; 256 = 2.0 ). Therefore, (using an offset value of 0) a luminance filter value of 128 does not change the brightness level; whereas a value of 256 will double the brightness level. A value less than 128 darkens the movie.
Default is : Not enabled, (equivalent to Filter value: 128, Offset: 0).

DeMacroVision:
Remove macro vision protection from the movie.
Default is : Yes

Deinterlace Filter:
Use this when your source image is interlaced and you want to remove the interlacing to produce a progressive NTSC movie.

Explanation: each frame of a 30fps movie consists of 2 separate fields, each field consisting of half the total number of scan lines for an entire movie frame -- one field is referred to as the even field, and the other is referred to as the odd field (or, they may be referred to as the lower field, upper field, or as the primary field, secondary field) -- so a 30fps interlaced movie would contain 60 fields. After deinterlacing, there will still be 30 frames (but only 30 í░fieldsí▒, each í░fieldí▒ now containing the total number of scan lines). Note the following warning.

Warning: if you explicitly set the deinterlace option to, for example, the odd field, and the video uses the even field as the primary or dominant field, the deinterlacing will produce a í«jerkyí» motion. You can experiment and just make a clip of 10 images to see if you have used the correct field as the dominant field.
Interpolate mode: interpolates the even field (you lose a bit of quality for SVCD, but this option always works)
Default is : Interpolate
