Extract Audio / Vidéo from Blu-Ray for Authoring and re-encoding

Hi,

We had a Blu-Ray made at a lab from an HDCAM Master. I would now like to extract its content in the form of video / audio track, without quality loss (in short, rip it) so that I can create a Blu-Ray authoring with menus, pop-up menus, different audio tracks and subtitle tracks.

Looking at my soft / hardware gear and what's available on the "not too expensive" market, I'm most probably looking at an authoring on Adobe Encore.

I'm on a mac and I have tried to rip the Blu-Ray to .mkv with MakeMKV, convert the audio / video to high quality .mp4 with h264 codec in MPEG Streamclip and then import in Encore, but I feel like there are some losses at each step of this process, starting with some bitrate limitations in MakeMKV.

Any advice / guidance on the process?

on a sidenote, does anyone feel like I do that it is taking a long time for Blu-Ray to really pick up in terms of standard for HD video? There are very little software built to work the format, arguably because it has been conceived as a more protected format than DVD, but still...I feel like it should have become the standard "prosumer" format for 2 or 3 years now.

Thanks for your time,

Colin
