Understanding size dimensions when exporting a still Image sequence from a video

Hi,

I'm trying to export a still sequence from a video. I need the still images in the sequence to all be a specific size in mm (10.26 x 7.49mm to be exact!)

When exporting the images sequence, the Render Video dialogue box allows you to choose a custom size but I can't tell what kind of units this is measured in. Is it pixels? If it is pixels how does this translate to mm and the size I need?

Thanks

    The base unit of all pixel picture is pixels. All the rest is deviated. The size in mm or any other length measurement is done by using a density factor: dpi (dots per inch). It is general use to say that for print you need 300 dpi.

    The easy part to find out how this corrolates is exporting a picture, opening it in Photoshop and going to Images size to play with the parameters. If resample is on, the computer resamples the image (changes the pixel size) to the parameters given, if resample is off, Photoshop does not modify the pixel size, but adapts all related parameters.
