I found this code and I would like to use it in conjunction with the timeline that when moving the timeline also moves the slider in conjunction with the timeline. It works very well like this one, but if you could add that the viewer updates the images according to the time of the timeline would be something…
Not a fix for that tool, but I just typically set a video or image sequence as a texture on a plane when I want the red in Max. Then it just works with scrubbing.
