Yeah, sure is a shame that this great idea for a shot has come in as an afterthought during the esit stage. It certainly would have been easier to plan the shot with the effect in mind but never mind.

If it's blood splatter though then I'm assuming it is only a short clip of a couple of seconds or do you intend to recolour the blood splatter oint he wall (or wherever) in every scene/shot afterwards as well? If it's just a couple of seconds then you'll be able to paint each frame in a reasonable timescale.

just remember thought that if you use a graphic poackage like Photoshop then do not simply 'paint' on the original image but use the pen tool to create your 'mask' on new layers. Save your 'project' as a Photoshop file and save as back as the format for your edit. That way you can revisit the 'project' later without having to redo it all because a few odd frames were wrong.
