I know there are threads about video quality but I don't get some of them clearly. I'm using Imtoo MP4 converter 3.1. There are many options for convertering. I have been using iPod touch widescreen converting mode. It is 768 (not sure) x 408 and 1500kbps with audio 128kbps. There are several options luke 680 x 480 and 480x 320. What would be the best quality for watching movie if the bibrate is all same to 1500kpbs and other options are same. What SIZE( number x number) should I convert to ? Thank u Extra: what is the zoom in the option? Like letterbox, or medium and that stuff? Does it matter to quality or size and stuff?
