Now go to the "Audio 1" section. Use the "Select" button to load the AC3 file DVD2AVI saved earlier on. If you want to keep the AC3 audio, select "Just Mux", otherwise, select "MP3, custom Parameters". Most of the options will be filled in for you automatically, but you do need to set the "Transcoding Parameters". Use the drop down list to select your options (note : "--alt-preset 160" means the MP3 will have a bit-rate of 160). Repeat the same for "Audio 2" if you have two audio tracks.







We're nearly there now ... Return to the "DivX 5" section and press the "Add Job to Encoding Queue" - you should be prompted to either start the coding now, or add more jobs to the queue before you start. You can always add to the job queue afterwards, if you wish. If you choose to start the job now, GKnot will start working, calling up different programs and in a short while, your encoding should be finished - during this time, you do not need to do anything, and you can still use your computer for other tasks.







Finished !! (and if you're interested, the 191 MB VOB file for BTTF 3 Chapter 19 was compressed to about 63 MB - I set 65 MB for the video, so the file size is quite accurate, but that's expected with DivX 5.x - with excellent video and audio quality, as expected)
