Blu-ray ripping, editing, and burning
Posted by Shaun Fitzpatrick on February 23, 2012 at 5:37 pmI am looking for the best way to rip a blu-ray to a file, edit that file in Vegas Pro 10, render it, and burn the edited file back onto a BD-R. I want to do this all lossless, so the blu-ray image looks as good as it did on the original.

If the Blu Ray disk is not protected by HDCP, then there are many Blu Ray ripper programs online.

This is practically impossible. DVDs and Blu-Ray disks contain highly compressed data. They are in a viewing format and do not edit well.

February 24, 2012 at 7:07 amYou’re not going to be able to edit Blu-ray video losslessly… it always compressed, and will have to be re-compressed for re-authoring. But if it’s not copy protected, you can use numerous programs for ripping… or just find the MTS files and drag them into Vegas.
Maybe. Blu-ray is a superset of AVCHD 1.0 (AVCHD was actually created, for consumer video recording on DVD or BD, from the BD specs). So many Blu-ray videos are encoded in AVC video and AC-3 audio. The differences possible here: AVCHD 1.0 is limited to 24Mb/s; Blu-ray can a bit over 38Mb/s. The AC-3 on AVCHD is either stereo or 5.1 channel; BD can support 7.1 channel AC-3 as well.
Then the craziness sets in… that’s just one set of possible media stream types. Video can also be MPEG-2 or VC-1 (aka, the standardized Windows Media video format)… Vegas shouldn’t have any trouble with MPEG-2, and it certainly can edit VC-1 (in theory, it’s easier than AVC, but there’s far more work being done to improve AVC). And there there are audio formats, nearly a dozen.
A good ripping tool would help with some of these odd formats, offering you the option of transcoding audio.
The other issue to consider… while a simple re-encoding shouldn’t affect video quality all that much, it might here. Vegas doesn’t support higher AVC bitrates, and of course, if you’re editing a professionally produced commercial video (which you probably shouldn’t be, but just throwing this out), that video will have been mastered by an encoding engineer… the quality of the AVC is hand-tweaked. The AVC I get on my Blu-rays is very close to the quality I see out of my camera. But a high quality Blu-ray is potentially better than all consumer and most lower-end pro camcorders. You will reduce the quality of that, re-encoding that. If this is a self-made Blu-ray from a client asking for changes or something, quality should be no problem.
