While GANool as a website may be gone, the encoding standard they set for "Semi" subtitles lives on in the memory of every Millennial and Gen Z film buff who grew up filling external hard drives with these compact, beautifully formatted MKV files.

A Review of the Top Semi-Trucks from Ganool in 2018

While technically a July release, CAM and pre-DVD rips started appearing on GANool in late June 2018 in South East Asia, fitting the "Semi 2018" search window.

In 2018, Indonesian home internet (Indihome) was suffering from international throttling, and mobile data was expensive. GANool files weighed only 700MB–1.5GB for a 1080p movie, whereas a direct BluRay would be 25GB. The "Semi" encoding used the x265 codec early, making files 40% smaller than x264.
