Output resolution in pixels.
PAL: 352 x 288, NTSC: 352 x 240,SVCD is 480*480
Default is : 352 x 240

Video Bitrate:

Video bitrate of the output MPEG file.
For VCD the video bit rate must be between 650 and 1150 Kbits.
For SVCD the video bit rate must be lower than 2600 Kbits (2376 recommended).
Default is : 1150

Audio Bitrate:

Audio bitrate of the output MPEG file.
For VCD the audio bit rate must be 224 Kbits.
Default is : 224
Motion Search:
Compression speed optimization . You may get noise around motions
Good : best quality (slow)
Normal : normal quality
Bad : Bad quality (fast)
Default is : Good
Mux Rate:
Increase the multiplexing rate by Mux_Rate% . Use this to avoid underflow.
Just increase it but the output file will grow up a little.
Default is : VCD = 1.4, SVCD = 5.6
VBV buffer size:
Size of the VBV buffer 20 recommended for VCD, 112 for SCVD.
Default is : 20
Quant matrix:
The quant matrices that iSofter DVD Ripper uses to compress video data are defined in source code. iSofter DVD Ripper determines which one will be selected automatically. Options are,
1) default,
2) MPEG standard
Default is: default
Check Standard:

Default is: default
Expert:
Video format passed to the premiere plugin (compatible with the Video Server)
and to the AVI codec.
Only RGB and YUY2 are supported for AVI
YUY2 is in fact a 4:2:2 YUV format (very good for DivX encoding)
The internal MPEG encoder works only with 4:2:0 this setting is ignored
Default is : RGB24
Pulldown 3:2:
Convert 23.976Hz to 29.97Hz (NTSC Only).
Default is : None
Audio drop down box:
You may select one of the following audio options,
1) Disable - no audio is output.
2) Store to WAV - produces uncompressed 16 bit stereo at 44.1 KHz.
3) Use MP3 - produces MP3 audio format. Selecting this option will enable the adjacent "AUDIO" button. Click the "AUDIO" button to select MP3 options for bit rate, quality, channel (stereo or mono), and settings for the low pass/high pass filter.
4) Use ACM.
NOTE: If you want to export audio as an AC3 file, then select option 1) above ("Disable" option). Make certain that you have also selected, "Export AC3 stream" AND have checked, the "Dolby Surround" box in the "Audio" section of the "Input Settings" window. iSofter DVD Ripper will then output an AVI file and an AC3 file at the same time.
Codec:
From the drop down list box select the codec to use in the output file.
Multi Pass:
Allow the audio and video to be read in 2 pass. You can use it if you
encode with TMPGEnc and do a 2Pass VBR.
UNCHECK this if you do CBR or one pass VBR.
Please read readme_1st for more details.
Default is : No
Export (AVI+Premiere):
Video format passed to the Premiere plugin (compatible with the Video Server) and to the AVI codec.
The YUY2 format is in fact a 4:2:2 YUV format (very good for DivX encoding) Options for the color spectrum of the output file are,
1) RGB24
2) RGB32
3) YV12
4) YUY2
Video Resize:
Video resizing filter.
Nearest neighbor : 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.
Max frames:
Maximum number of frames to encode.
Default is : 10000
