I took a peek and this is all coming back to me now.
First off, we are looking at two different datasets in our Landsat comparisions:
Golden is using 2016 data: https://storage.googleapis.com/earthengine-timelapse/herwig/earthtime_annual_1984_2016/v14/1068x600/1/0/0.mp4
Staging is using 2019 data: https://storage.googleapis.com/timelapse-test/tmp/herwig/export/cmu_20200106_resampled/1068x600/1/0/0.mp4
I'm recalling again Chris H. saying that he previously (back in 2016) had full control over ffmpeg settings and was able to apply various sharpening filters. (this is why 2016 set looks almost too sharp) This is no longer the case now at Google and they are forced to use company wide settings and can only modify things like fps and dimensions.
If we want, we could run our own post sharpen filter on the tiles. I spent 30 seconds and got this result (right side is the sharpened version):
Of course the downside is that we would have to host from our own Google bucket, which may be undesirable.... Would also take a bit to run through all 12 levels of tiles.
