We are using the Pro version of your product and before buying the product, we have a question - what setting should we set in order to have an AVI format file with a 350MB size for a video with a 45 minute running time?

Can we use the divx mpeg 4 compression or do you recommend something else? Can we change the aspect ratio? We did notice a setting of 640x480 and we would like to use 740x544.
