NOTES ON SSIM
The SSIM measures the accuracy of the outputted encode v the source. If the source is sharp, an encode score of 90+ will also be sharp and look extremely close to the original. If a source is blurry and/or out of focus, an encode score of 90+ will still be blurry and out of focus. SSIM only measures how close it is to the source material. An "e;S##"e; is a score where filters where NOT used and an "e;FS##"e; is an encode where filters were used, usually for insane amounts of grain/noise. Filters can tilt/cheat the score in a positive way but look far different from, but possibly "e;better"e; than, the original so bear that in mind. Again, the SSIM score represents how accurately the content has been encoded when compared to the original. Addition things can skew the rating down such as home video footage, older-grainy footage, etc... To make things simple, and they are really not, just think of it as a grade; where a S91 would be an A and a S75 would be a C effort.
NOTES ON ENCODE SETTINGS 
A few notes about bitrate: Most of these encodes have bitrate caps to prevent spikes in bitrates that cause hiccups when streaming remotely. All content is test-encoded separately before settings are chosen and in general a CRF value is chosen that will keep the average bitrate safely below the set MAX rate without losing too much quality. That said, these cHorse encodes are always capped at 4-5Mbps MAX for streaming ease. If a 2-pass ABR (average bitrate) setting is used it's only because no amount of filtering would keep the bitrate down. This year encoding will move to sourcing, when available, straight from the 4K UHD and/or remuxes thus leaving the DV (also, when available) and HDR data in tact for a better viewing experience on devices that support it. This should work for most users when decently recent tech. Enjoy!
