I'm new in Scratch. My problem is this: I have converted a TIFF sequence (which I previously exported from DaVinci) to JPEG2000 to create a DCP. I've made the DCP and everything was fine, but now I need to make an adjustment in the editing that affects just a few frames. It doesn't change the duration. What I want is to replace 180 frames. I've already done it into my TIFF sequence, so my film is ok now in Scratch. But I don't want to render again the whole movie, I just need to export this 180 frames in JPEG2000 format. I suppose there must be a way to select a range just to export this frames with the same name, but I'm completely lost in Scratch. Can anyone help me?
