Video and Audio Properties
Frame Rate
Frame rate is the number of times the picture updates per second. The higher the frame rate, the smoother the motion will be in the video. There is no benefit in increasing the Frame Rate higher than that of the original DVD. Generally, you should only lower the Frame Rate, if you have chosen a very low Bitrate.
Bit Rate
Bitrate is the amount of information that is stored in the file to represent each second of the video. Lowering the bitrate will reduce the quality of the recorded audio and create smaller files. If you set a bitrate of 2000 Kbps, a 10 second video file will contain 20,000 kilo bits of information in the video (There will also be audio information). The higher the bitrate, the higher the quality of the video and the larger the size of the file. Generally, smaller dimensions will allow you to use a lower bitrate and still have a good quality picture.
Dimensions
By default, ripped files are at the largest size playable on the selected device. You can select other supported sizes from the drop-down list if you select Change Dimensions. Note that choosing Custom dimensions other than the ones in the drop-down list may produce a file which the device may not be able to play. Reducing the dimensions and lowering the Bitrate can produce smaller file sizes at the expense of low quality.
The Aspect Ratio of a video image is the relationship between the width and the height. Standard TV has an aspect ratio of 4:3, meaning that it is 3/4 as tall as it is wide. Movies and HD TV have wider pictures, meaning a different aspect ratio. If you choose to Change dimensions, you can unselect Lock Aspect Ratio. If you know that you are converting widescreen movies, you should be sure that the dimensions you select are in the correct ratio before converting.
Frequency
Audio Frequency is the number of times that the audio signal can be adjusted per second. Higher frequency values give better sound quality but also increase the size of the audio. Generally, use higher quality settings for music and lower for speech. Lowering the Frequency will reduce audio fidelity.
Channels
Select Mono to include only one sound channel with your output file, and Stereo to include channels for both left and right speakers. Using Stereo produces slightly larger files.
