Hello Henry. Sorry for some missing information in the manual. As you know, once any automatic dirt pass has completed, the dirt matte may be toggled on to visually see where each repair was made, allowing the user to undo any unwanted fixes or artifacts. You may save this matte with the clip using the clip menu, but as you have noticed, saving with the clip doesn’t provide any use once the clip has been committed. To make further use of the dirt matte, save the matte with the menu as you have found. After the current clip has been comitted, the new “rst” version may load the previously saved matte. Matte files are saved by default in the “data” directory. Now to make use of the dirt matte in the rst (or any subesquent version of the clip), you must associate the original or “dirty” version of the clip using the F2 Assign Original. This effectively links the current “clean” version with the original “dirty” version. You may then continue selectively undoing any unwanted fixes.
