BD-RB: Enforce AVCHD-compliant video on BD25 full backup?
I've searched and not found this question asked previously.
I'm wondering if it's currently possible to configure BD-Rebuilder such that all video streams that are reencoded are AVCHD-compliant streams (either with the 18 Mbps DVD-media limitation or otherwise the 24 Mbps "other media" limitation), even when the output mode is full-backup to BD25. The reason for this is that I anticipate (perhaps incorrectly) that certain tablet computers etc may start to become AVCHD-licensed/compliant players, in which case it would be incredibly nice to be able to play my BD25 backups without reencoding the video and instead, at most, reencoding audio only and/or remuxing (either via BD-RB in movie-only output mode or otherwise). Bonus question! Concerning the video stream aspect only: besides the video bitrates and other restrictions given for AVCHD on its Wikipedia page, is AVCHD (prior to the 2.0/Progressive addendum) strictly a subset of the general Blu-ray AVC video encoding limitations, or are there additional, "hidden" restrictions (possibly relating to level, profile, GOP lengths, etc etc) that AVCHD enforces? |

Create a profile for MP4 (not iPOD or iPAD) or MKV with the correct maximum bitrates and AC3 as the audio output format, BD-RB will, by default, use all the the other settings that makes it compliant.
AVCHD is a subset of the BD. So an AVCHD source will always work for BD authoring -- but a BD source won't necessarily always work for AVCHD authoring. Last edited by jdobbs; 29th July 2012 at 16:34. |
