OK so I am running into some issues on DaVinci Resolve right now using an Ext Matte in a color correct node, and I am wondering if I am doing something wrong, if this is how it is supposed to function.
I have some shots that were shot just as the sun was going down at the end of a shoot without enough lighting. So the exterior is way too dark, and it has to match the daylight exteriors. Now I tried to do matte’s in DaVinci and even tried the new smart mask on the people, but I found I could get a better matte in After Effects with the Roto Brush. The matte is the exact same size as the shot in the sequence in the show, for this shot 1 second and 10 frames, so I made a matte that started at the first frame and is exactly 1:10 in the frame, but when I add the Ext Matte to the shot, while the scale matches up, it certainly does not match first frame to first frame.
So I unchecked Lock Matte to be able to adjust the clip manually. And had to adjust the zoom, tilt and offset to get it to work. I don’t get why I have to set the offset to -14, since the matte is the same length as the visible portion of the shot in the sequence, and the full shot is much longer than 14 frames. SO I AM TOTALLY CONFUSED BY THE OFFSET.
Even weirder to me than the Offset though is the tilt. I had to set it at -571 to get it to line up (and why can’t there by a match for position, but change the offset?) and that is weird to me, because I have below the transform for that clip within the edit panel. The zoom matches at .6, but the position is -150, so where does the -571 come from? I should be able to match the 2 clips by using the same numbers, not completely different numbers! WTF!
Not sure what I am doing wrong here, but if anyone can explain to me why the offset and tilt are like they are it would be greatly appreciated.
