Why does Handbrake show less duration of the blu-ray?

[batemanj]

Hi,

I have this file structure of my Blu-ray which I would like to encode using Handbrake.

\---BDMV
| index.bdmv
| MovieObject.bdmv
|
+---BACKUP
| | index.bdmv
| | MovieObject.bdmv
| |
| +---CLIPINF
| | 00000.clpi
| |
| \---PLAYLIST
| 00000.mpls
|
+---CLIPINF
| 00000.clpi
|
+---PLAYLIST
| 00000.mka
| 00000.mpls
|
\---STREAM
00000.m2ts

If I drag BDMV folder onto HB, it says "No valid source or title found" so If I drag the "STREAM" folder OR "00000.m2ts" then Handbrake (HB) shows the length of the video as 2:37:10 (incorrect)

IF I play the m2ts file using VLC it shows the duration as 2:39:01 (which is correct). So I generated MKV using mkvtoolnix which shows 2:39:01 (correct). Then why does HB miss out some duration? I want to source Bluray folder to HB rather than the MKV. Please advise how to source BD source to HB and yet get full 2:39:01?


Thanks

Something peculiar that the timing of m2ts is not always determined correctly (I've seen it before also)
Just use the MKV - no degredation of the file with mkvtoolnix
