well, I am working with xdcam 1080p footage...
and I need png sequences for post production.
png's needs to be 16bit...
but, when using 'render image sequence' script, there is no options for png format.
does anyone know is it possible somehow to 'tell' vegas to export png's with 16bit depth? or maybe, if project is set to 32bit, vegas will export it properly?? hm...

PNG is an option in the image sequence script. However, you might want to look at the new render option in Vegas Pro 9 which can render image sequences in many different file formats.
