I'm trying to make a 5-year timelapse of monthly NDVI composites. I apply a Hollstein mask, make composites and fill the masked area with mean NDVI pixels of the entire timeperiod. Of course this method is questionable, and there are many ways, but I am mostly stuck on producing the timelapse video itself. I use the GIF production because I only use one band. In GEE my composites look like this: But when I produce a GIF timelapse, it looks like this:
I tried multiplying the NDVI by 100 to see whether that would induce more colour contrast, I tried to add more colours to the visualisation parameters, but the contrast remains the same.
