Of course. Converting a video from PAL (25.0 fps) to NTSC-Film (23.976 fps) does change the playing time if you use the slowdown method.
But converting a video from NTSC (29.97 fps) to NTSC-Film (23.976 fps) does not change the playing time if the video was telecined and can be reverted to progressive using IVTC. Therefore, MeGUI does not need to offer any audio conversion. The audio does not need any conversion, because the playing time won't change. But only if you can invert a telecine. |

I have a Blu-ray that causes eac3to to show only one playlist (the wrong playlist), even though playing index.bdmv plays a different one (the correct one). I've zipped the contents of the PLAYLIST folder and included a few files for debugging.. if madshi still secretly develops this.

With TSmuxer, check "downconvert True HD ..." in track options and choose demux as output format. Don't worry, that's an extraction, not a conversion (encoding).

Anyway, are you sure that the real playlist and the one selected by eac3to are really different? Often there are multiple duplicates, and eac3to simply selects one "by random". |

There is something to extract, for example the latest version of mkvmerge can get the embedded AC3 track for you.

The bug #86 with the inversion of the left and right eye views when displaying the content of a 3D playlist with the MVC_Base_view_R_flag true is partially fixed.
When eac3to is launched with the BD path as the argument, or with the playlist, it works fine: Code:
C:\>eac3to.exe Y:\BDMV\PLAYLIST\00852.mpls 1) 00852.mpls, 00001.m2ts, 1:34:02 - Chapters, 20 chapters - h264/AVC (right eye), 1080p24 /1.001 (16:9) - h264/MVC (left eye), 1080p24 /1.001 (16:9) - DTS Master Audio, English, multi-channel, 48kHz - DTS, French, multi-channel, 48kHz - AC3, Spanish, multi-channel, 48kHz - AC3, Portuguese, multi-channel, 48kHz - AC3, Danish, multi-channel, 48kHz - AC3, Finnish, multi-channel, 48kHz - AC3, Norwegian, multi-channel, 48kHz - DTS, Russian, multi-channel, 48kHz - AC3, Swedish, multi-channel, 48kHz - AC3, Chinese, multi-channel, 48kHz - DTS, Japanese, multi-channel, 48kHz Code:

@all users Please read ITU-R BS.775-3 to understand for what add LFE is not recommended for downmix. Use -mixlfe at your risk.

Pleasure! It was about time...
Thanks, appreciated! Quote:
Originally I mixed left, right and surround channels with 1.0, and the LFE with 0.7071. The reason for using 0.7071 for LFE was because it was originally only one channel/speaker, but I've mixed it into both the final left *and* right channels. So I had to half the volume of the LFE to not increase its final playback volume. Now ITU 775-3 suggests to use 1.0 for left/right channel, but 0.7071 for the surround channels. The ITU idea is that the left/right channels should have higher priority than the surround channels. If we accept this idea, it should also be applied to the subwoofer. Why would we lower the surround channel volume for the mix, but not the LFE volume? Because of that I've used the original matrix, but added an 0.7071 factor on all channels (including LFE) except left/right. This is how I ended up with 0.7071 for the surround channels and 0.5 for the LFE. ITU 775-3 does suggest not to mix the LFE at all, and IIRC that's eac3to's default behaviour, anyway. But *if* the user wants to mix the LFE, the volume should make sense, and since I just lowered the surround volume, I thought it would make sense to lower the LFE volume (when -mixlfe is used), accordingly.
