These top level controls let you choose how to draw patches with which to repair temporally unstable dust and dirt in the frame, whether or not to show their on-screen controls, and how.
— Navigation Controls: Four buttons let you jump to frames on which you’ve drawn patches. There are four buttons:
— First Modified Frame: Jumps the playhead to the first frame of that clip with a patch.
— Previous Modified Frame: Jumps the playhead to the last frame back with a patch.
— Next Modified Frame: Jumps the playhead to the next frame forward with a patch.
— Last Modified Frame: Jumps the playhead to the last frame of that clip with a patch.
— Draw Rect: Click and drag to place a rectangular patch of any size from one corner to the opposite corner. Once drawn, you can click on any edge of the overlay and drag to reposition it.
— Draw Ellipse: Click and drag to place an elliptical patch of any size from one corner to the opposite corner. Once drawn, you can click on any edge of the overlay and drag to reposition it.
— Place Patch: Lets you place small patches specifically for tiny details such as dead pixels.
When you choose this option, a New Patch Size slider appears that lets you adjust the size of the patches you’re about to place prior to placing them. Once drawn, you can click on the edge of any patch and drag to reposition it.
— New Patch Size: (only when Place Patch is selected) Lets you choose how large of a patch to place using the Place Patch tool.
— Show Patches: This checkbox lets you show or hide the onscreen outline of every patch in the Viewer.
— Reset Frame: Clears all patches from the current frame.
Patch Type
There are six methods you can use to attempt to fix the contents of a selected patch. When drawing new patches, the currently selected Patch Type will determine what the next patch will be. When you’ve selected an existing patch, changing the Patch Type will change how that patch works.
— Auto: The default method. Once you’ve drawn a bounding box, the two frames prior to and the two frames after the current clip will be analyzed and compared to the current image. The best of these 5 frames will be sampled to remove the imperfection in the current frame. Images two frames away are prioritized since that will avoid the appearance of frozen grain, but only if they’re a suitable match to the content of the current frame.
— +/- 1 Frame: In this mode, if you draw a bounding box from left to right, the next frame will be drawn upon to remove the imperfection. If you draw a bounding box from right to left, the previous frame will be used.
— +/- 2 Frames: If you draw a bounding box from left to right, the image two frames forward will be drawn upon to remove the imperfection. If you draw a bounding box from right to left, the image two frames back will be used.
— Spatial: Automatically fills the interior of the selected patch with pixels drawn from the surroundings of the patch, using the Fill Method. This works well for small blemishes, but for large blemishes a pattern might be discernible, which gives away the effect.
