You can copy Blu-ray to ISO images to protect your discs with the original video and audio quality. But the size will be also nearly original. To get the smallest size, the best way is to rip Blu-ray to HEVC/H.265 video cause H.265 can compress video twice than H.264/AVC codec with the same picture quality. Generally, a 30-40GB can be compressed to 7-15GB in H.265/HEVC MKV. Some people would worry that it will cost too much time in that HEVC encoding is CPU heavy.
If you are using NVIDIA 980TI, you won’t need to worry that. NVIDIA 980TI supports HEVC encoding acceleration. So if your Blu-ray Ripper supports NVIDIA CUDA or NVIDIA NVENC hardware acceleration, you can same a lot of time on Blu-ray to H.265/HEVC encoding on NVIDIA 980TI. Of course, not only NVIDIA 980TI, all the GeForce GTX 9...Read More
