[robfilms]

i need to scan images that will be as part of a production's b roll.

if i shoot sd what dpi should i set my scanner for?

i imagine for sd the frame size should be 640 x 480?

what would the dpi be for a hd production?

how about hd frame size?

all of these scanned images will be edited in final cut pro

obviously, i know very little about doing this correctly.

any and all specific input would be greatly appreciated.

thanks in advance for sharing your experience

be well

Basically the frame sizes are 720*480 for 4:3 SD and 1024*480 for widescreen SD. The later will be automatically changed into 720*480 anamorphic by the video editor. For HD the frame size is 1920*1080. DPI setting does not matter at all, as long as it is something sensible like 72 or 300 dpi. Middle quality JPGs are good enough.

BUT: I recommend you do the pictures in larger size. This is not at all for quality, but for the possibility of doing pans and zooms and reframing inside the picture. For that reason I usually import my photos to the video editor about double the size the final product will be. For SD 1500 or 2000 pixels wide, for HD 4000 pixels wide (maximum allowed by PPro 1.5).
