How do you make a video that overlaps the result of node processing on the color page on the original video, which is common in color grading tutorial videos?
I think there are some ways to do it, but I don't think it's necessary to think hard.
1. On the color/edit page, divide the color graded clip on the timeline into the number of color nodes
2. Return to the color page and set the node ON/OFF for each clip
In the tutorial video for color grading, I think that transitions are used in addition to simply switching between color pages, so I think you can set them in the same way as general video processing.
By setting transitions between clips, you can create a video with a nice color gray effect.
