ImTOO DVD Ripper Platinum 5.0.51.1211 Online Manual

Video

Output Frame Rate
Set output frame rate for video files. Five available options: “Keep original”, “23.976(NTSC)”, “24”, “25(PAL)”, ”29.97(NTSC)”, “30”.
Hint: DVD Ripper Platinum will not automatically set this option. If you set a frame rate different from that of the source program, the converted program will have the set frame rate. Besides, please avoid the conversion between different television systems, such as conversion between NTSC and PAL, or between PAL and NTSC.
Default: Keep original
Detect progressive 24Hz
Automatically detect progressive 24Hz sources. Detected source frame rates will be displayed in the main interface.
Default: checked
Force progressive 24Hz
Force the source to be a progressive 24Hz source
Hint: The “Force progressive 24Hz” box is only checkable when the “Detect progressive 24Hz” box is checked.
If you think the detection result incorrect, you may consider checking the option.
Default: unchecked
Audio/Video synchronization
If this box is checked, audio and video signals will be synchronized again according to the cycle.
Hint: if you have selected values different from the source program in previous options, please check the box to ensure audio/video synchronization of the output program.
Default: unchecked
Deinterlace Filter
If the source program is interlaced, while you wish to deinterlace to generate a progressive program, please check the box.
The interpolation (interpolating even field) will definitely work. However, it will also compromise some picture quality when making formats such as SVCD.
Default: Interpolate
iDCT
Set Inverse Discrete Cosine Function Transform.
MMX is the fastest and is suitable for most CPUs, while FPU provides the best quality.
Default: Automatic detection of local CPU

DeCSS

Simply leave the original default value for DeCSS unchanged. It needs the installed ASPI to perform drive authentification and read files over 1GB in a DVD.
If you get a confused video, please try to change the mode for Key Search.
Key search
Set the mode for CSS key search.
Default: Once
DeMacroVision
Check the box to remove the macro vision protection of the movie.
Default: checked

Subtitle

Offset(pixel)
Set the pixel offset in vertical direction for subtitles.
If the subtitle is displayed outside the screen area, ImTOO DVD Ripper Platinum will automatically adjust the value for the option.
Default: 0
Hint: When setting “Offset” values, a positive value indicates a downward offset, while a negative value indicates an upward offset.
Original colors
Check the box to keep the original subtitle color.
If the original subtitle is too dark, please do not check the box.
Default: checked
Besides, you can also determine whether to keep the original color of a subtitle. If the original subtitle is relatively dark, it is recommend that you don’t need to keep original colors.

Audio

Downsampling
Note: DVD audios generally have a sample rate of 48000Hz or 44100Hz (with certain exceptions, of course), while actually such a high sample rate is not necessary for most of the times (meanwhile, certain devices do not support ultra high sampling rates). Therefore, you can decrease the sample rate by downsampling. Downsampling can be realized together with bit rate. Of course, the bit rate can be kept unchanged during downsampling.
Downsampling provides the following modes:
Normal quality 48.0KHz to 44.1KHz (fastest)
High quality 48.0KHzto 44.1KHz (very slow)
No downsampling
44.1KHz (no conversion) -- If your source program has a 44.1KHz audio, and you wish to keep the rate unchanged after conversion, please select this mode.
48.0KHz (no conversion) -- If your source program has 48.0KHz audio, and you wish to keep the rate unchanged after conversion, please select this mode.
Default: No downsampling
Volume
Set volume for output audio.
For most DVDs, the default volume is already sufficient.
Besides, you can use the Detect button at the right side of the Volume option to detect the real time volume of source DVD. For example, you can detect a clip that you think it has a high volume and, according to the obtained volume value, enter a proper value for the Volume option.
Default: 3
Dolby Surround
If the box is checked, the better 5.1FX will be maintained in the stereo.
Default: checked

Save your DVD drive

Set an amount of temporary buffer cache to avoid frequent read/stop of DVD-ROM.
Typically RAM will be set as temporary buffer cache so that the conversion will be faster. Of course, you can use hard disk space as temporary buffer cache.
Typically, files will be saved in a temporary system directory. Therefore, before conversion, please make sure that there is available temporary directory.
Default: Cache size = 10MB; location = RAM.

Luminance filter

Set luminance of the program.
If the box is checked, luminance rendering will be used.
Hint: use luminance filter to modify the gain value. If the gain is less than 128, the image will become darker; when higher than 128, it will become lighter. (Typically gain values are multiples of 64, for example: 0 = 0.0; 128 = 1.0; 256 = 2.0)
The Offset is based on the gain.
Default: unchecked (i.e., gain: 128; offset: 0)
