J:
I Use Pro Coder3 By Canapus , I can upscale the letter box and change the bit rate; but it doesnt make it HD(even though itis a HD-2 codec .M2T), You have needed to shot your video with a HD cam to get Hi-def. They only purpose for upscaling is the letter box to display corecttly on a LCD screen(Dosent change the quality its the same). Other that I see no reason to up scale.
The only way I know how to upscale is by useing a hardware base rending card such as Blue Fish, and they are very costly usally upscaling cards start about 5k , Probley cheaper to buy a HD cam.
If it was just a software issue to get true Hi-def there be no need forHD cams.
Just my thoughts and Exp.
