I need to rip/convert some of my home movie DVD-Rs to .avi files with minimum loss of quality. Don't need the DVD menu or anything like that, just the main content.
Can anyone recommend a good program? i'm happy to pay for the license if it's a good program, so doesn't need to be free
I know how to rip ISO files from DVD-Rs, but I'm clueless as to how to convert them to AVI and keep the quality. Any advice much appreciated

your first step.. don't use AVI. xvid is a completely dead codec. If you use xvid, you WILL have quality loss, and significant quality loss. xvid was designed to be small, but doesn't keep quality at all. The way it compresses the video from 4 GB to 700 MB (or whatever your designated field is) is to compress the video greatly, shrinking the aspect ratio, draining the colors, and creating a ton of macroblocking on frames it removes. Look into ripping to x264 .mkv or .mp4. you can rip mostly flawlessly as long as you properly fill out the aspect ratio fields and frames per second. www.videolan.org/developers/x264.htmltry this program |

(like mp3 is standard for music files now) i understand that conversion programs ask for frame rate, video bitrate, video size and stuff like that. but i don't understand how i'm supposed to know what values to enter. is there a way to find out what the original dvd uses for these values? i just want to keep everything as close as possibly to the quality of the original DVD. |
