4. Config and options

1). General

a. Misc

• IDCT - To select the CPU instruction to do IDCT (Inverse Discret Cosine Transform) according the model and performance of your pc.
• Buffer size - The buffer is used to store input video stream data temporarily. If you select to use RAM as buffer. you'd better not to change the default value 10 MB otherwise you know what you are doing. You can select the name of temporary file if you select Disk as buffer. The default temporary file is named as "WinxDP_output.tmp" and located in system temporary folder. You can change it to any other folder you prefer.
• Re-synchronize Video and Audio Periodically - Not always necessary. Default is no.
• Use ASPI - Highly recommend, especially for accessing large video file. Default is to use.
• Priority - Set the priority level of this process. Default is normal.
• Shutdown the computer when job is done - WinXMedia DVD 3GP Video Converter will shutdown your computer after all converting tasks is done if you select it.

b. FrameRate

• Input - 1)Detect progressive 24Hz, Detect 24Hz progressive NTC. 2)Force input to be a 24Hz progressive NTSC. This flag works only if Dectec progress 24Hz is checked. Use it if you think that the 24Hz detection doesn't work. Default is : No
• Output - Frame rate of the output video stream. 25 (PAL) or 23.97,29.97 (NTSC). Warning this value is not automaticaly set, if you choose a different frame rate from the input, a pull down will be performed. Avoid conversion between NTSC and PAL. Default is : 25

2). Input

a. Input

• Program Chain Index - Select specified program chain. Most of movies are stored in pgc 0. Default is : 0
• Angle - Select specified angle. Most of movies are stored in angle 1. Default is : 1 Normally needn't to change.
• Audio Track - Audio track to export and convert.
• Dolby suround - Enable dolby suround down mix. Allow to preserve better 5.1 FX in stereo mode. Default is: Enabled
• Volume - Gain of the audio output. No normalization is performed. A value of 1 can't generate distorsion (cracking) but the output sound may be very low. The default give a good volume for most DVDs. Make few clip of the movie where you know the volume is high and adjust this value in order to get a good volume. Default is : 2.5
• 48KHz downsampling mode -
  • 0 : Normal mode (fastest)
  • 1 : High quality (slower)
  • 2 : Export the source AC3 to a file, you can afterward select the output file by clicking on the SELECT AC3 OUTPUT button.
  • 3 : 44.1KHz (no conversion) Select this when you don't want to make sound conversion when you have a 44.1KHz source stream.
  • 4 : 48.0KHz (no conversion) Same purpose as choice 3, when the input frequency is not specified (A3,LPCM) it is usualy 48KHz
  • Default is : 0
• Subtitle - Specify the subtitle to display. Default is : None
• Offset - Vertical offset in pixel of the subtitle. This values is automaticaly adjusted if the subtitle goes out of the screen. Default is : 0
• Original color - Preserve original color from the IFO file Uncheck it if your subtible looks too much bold. Default is : Yes
  

b. Filter

• Luminace filter - Allow to adjust light of source. The Y plane is the luminance plane (in YUV format) Apply Gain*Y + Offset on the Y plane. Gain is 8.8 fixed point value. ( 0 = 0.0 ; 128 = 1.0 ; 256 = 2.0 ) Default is : Not enabled , Gain 128 , Offset 0
• Deinterlace filter - Use this when your image is interlaced (when 1 line / 2 is shifted) Warning if you set odd or even field you cannot be sure that it is the good field, Just make a clip of 10 images to see if you're right. Interpolate mode interpolate the even field (you lose a bit quality for SVCD but it always works). Default is : None
  

3). Output

a. 3GP/3G2

• Video Bitrate - Video bitrate of the output 3GP/3G2 video file.
• Audio Bitrate - Audio bitrate of the output 3GP/3G2 audio.
• Channel - Mono or stereo audio
• Sampling Rate - Audio sampling rate.

b. Misc

• Use Default Resolution - Use defaut output stream resolution, which is variant based on video format, output frame rate. If not checked it, you can set to use custom resolution.
• Zoom - Control how output video picture is cropped.
  Letterbox , medium and pan scan convert 16:9 to 4:3 ,Full doesn't correct the aspect ratio. If you have a 4:3 DVD Use Full. Default is : Letter Box (4/3)
• Resize - Video resizing filter.
  • Nearest neighbour : Get the nearest pixel. (no filtering)
  • BiLinear : very accurate Slow
  • BiLinear MMX: very accurate Fast
  • BiCubic : very accurate bicubic filter very slow
  • SSE BiCubic : SSE implementation of accurate bicubic filter
  • Works on PIII or K7 or higher
  • Pseudo BiCubic : not accurate very fast
  • Bilinear uses 2*2 nearest points to smooth the picture
  • BiCubic uses 4*4 nearest points to smooth the picture
  • TAP filters are 2Pass filters,they give best quality but are slower.
• All Frames - Convert all frames of DVD video.
• Part Frames - Convert part frames as specified.
• Pull Down - Convert 23.976Hz to 29.97Hz (NTSC Only). Default is : None

c. Volumes

• Splitting Volume mode - Specify how to split a large video file to multi-volumes.
• Volumes Overlap - Specify overlap between two continuous volumes.
• Default file name - Specify output video/audio file name, should not include extension.
