Kenzo thanks provide with link to fp8 v4 and i will put it into 2.6 with efficiency in mind
Stained video re encoding is lossy, its up to you and your mathematical skills to preserve and find balance between how lossy and small you want it or how big and with extreme quality
Its also up to the video itself, if the video has much of the same colour for example credits which black and white everywhere it will be able to reduce much without almost no quality loss
when i update bink re encoder i will provide a documentation too. or write it into manual itself.
I am also pleased to announce that i opened a video channel on youtube in which i will show you how to encode, compress with effieciency and i will also show you how capable reflate me and Zee have made
