The Flic chemical kit is clearly superior to those from Cinestill, etc., because it includes a stop bath, which allows a real, close tolerance development time, as well as separate bleach and fixer. This much reduces the prospect of less than a complete bleach, and therefore a less than complete fix. Good on those guys for doing it right!
THIS IS CRIMINALLY UNDERRATED! Oh my man, great videography work, great voiceover, it is great pleasure to watch your videos. I was in great shock, seeing only a handful of views... Well deserved sub from me.
You made some mistakes in developing too, as there are visible color crossovers. There are two common reasons for this - deviation in temperature and fixer in developer.
