blu-ray ripping and encoding tools
Seems the thread starter's new to blu-ray ripping.
Ways improve blu-ray ripping speed: use a high-efficient computer; use a bd drive of speedy data transmission; use cuda when it necessary (only for encoding- as jinjuku stated).
Tool for fast blu-ray to mkv ripping (copying):
MakeMKV - copies blu-ray to mkv without encoding, takes about 1-2 hours to copy one movie, keeps subtitles you like, free for 30 days.
Tool for fast blu-ray to mkv encoding (use cuda):
DVDfab Blu-ray ripper - encodes blu-ray to mkv using cuda tech, keep 2 subtitles, processing time depends on the settings (mostly video bitrate you use. 3 hours + to encode a 90min blu-ray at 12mbps on my i7 4GHz PC, free for 30 days.
Tool for both (copying and encoding):
Pavtube Bytecopy- copies blu-ray to mkv as MakeMKV does, and encode blu-ray with CUDA tech, keeps subtitles you like, free for 7 discs. If you're not sure about ripping or encoding, try this one.
Hope it helps.
