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.
I'll have to do some more work to track down a method to warp the flow properly in 2D mode. For now, optical flow cadence is a 3D only thing.
Made it say Optical flow cadence (3D only)
Made it hidden by default
Made it show when you switch to 3D mode
Made it not do the routines on the back end if not in 3D mode
optional checkbox to include optical flow in normal cadence
-starts by getting flow between turbo_prev_image and turbo_next_image.
- after getting the flow, it warps the turbo_next_image with negative flow to match prev
- then, normal image warping during cadence happens
- then it warps the flow field to match the animation, first converting it to relative for warp, then back to absolute flow
- I calculate the flow division for each tween value and divide that by two.
- it then applies that tweened flow to the prev and next image
