Option works in 2D/3D mode
Does a disposable generation before the actual generation to get the flow between previous image and the generation. Then, it discards that generation and warps the init_sample based on the captured flow before the actual generation happens.
- Takes twice as long (obviously)
- It can introduce smoothing, especially over time, but also adds a type of artistic consistency between frames.
- can be mixed and matched with any other modes, optical flow cadence, video, etc...
You can now color match against an image!
- the one caveat is that normal color matching is done with the prev_img. There is no prev_img for the 1st frame, so I had to force the color match on the output rather than the input. It makes the first frame look sharpened at times, since the histogram is forced on it.
I also fixed video color coherence
- I realized that it was never color matching on the first frame for video. You usually just wouldn't notice, since you're using the video.
- I also realized it was one frame off, fixed.
Once I tried some different images I realized that the color balance was RGB/BGR swapped on the color matches. Ooops! This fixes it. Perfect color matching after strength 0.
I wasn't thinking about it quite right before, and I was cancelling the wrong cadence section based on strength 0. This repairs it.
It now looks at the proper strength key (from the tween frame_start_idx) to see if strength is 0 and skip optical flow cadence if it is.
Also, fixes and condenses the reporting of whether it's a cadence frame or an optical flow cadence by combining the info with the tween reporting.
I made cadence skip optical flow on frames with strength 0. This won't actually help you unless your cadence start is aligned perfectly with your strength 0.
Made strength 0 reset color match, as if it were the first frame in an animation.
I plan to make a scene change schedule, at which point I can add a strength threshold value for scene changes and replace this code.
