BTW, personally I'm also modding all 24.000 Blu-Ray movies to 23.976. However, for such movies I store the original audio track, too, just to be safe... |

Will eac3to be updated to support muxing with x264's new --fake-interlaced?

Actually I think I jumped the gun. eac3to detects the source at 1080i60 and adds a fps value of 30000/1001 to the mkv header. So yes it works correctly. My apologies.
Code:
eac3to v3.18 command line: eac3to C:\Personal\Videos\hd_dts_sfx_long.264 C:\Personal\Videos\hd_dts_sfx_long.mkv ------------------------------------------------------------------------------ h264/AVC, 1080i60 /1.001 (16:9) Muxing video to Matroska... Added fps value to MKV header. Video track contains 573 frames. eac3to processing took 1 second. Done. |

I've found a peculiarity when reducing the bit depth of a file. I've got a sample here to reproduce the problem (if it is a problem). http://www.mediafire.com/file/yynhfkqgzm2/test1 24.flac If I try to reduce the bit depth from 24 to, say, 20 bits I get the following log: Code:
eac3to v3.18 command line: "D:\Vtemp\programs\eac3to\eac3to.exe" "E:\Video\test\eac3to test\test1 24.flac" "E:\Video\test\eac3to test\test1 20.flac" -down20 ------------------------------------------------------------------------------ FLAC, 5.1 channels, 0:00:18, 24 bits, 4786kbps, 48khz Decoding FLAC... Reducing depth from 24 to 20 bits... Encoding FLAC with libFlac... Creating file "E:\Video\test\eac3to test\test1 20.flac"... The original audio track has a constant bit depth of 24 bits. Processed audio track, L+LFE: constant bit depth of 20 bits. Processed audio track, R+C+SL+SR: max 24 bits, average 20 bits. eac3to processing took 3 seconds. Done. Thank you! |

Sorry, looks like mediafire is down.
Here's another link: http://www.tintime.talktalk.net/test1 24.flac |

Hi guys, I'm trying to encode a 6.1 DTS to a 5.1 AAC track with eac3to (using NeroAacEnc.exe for the AAC conversion).
I've encoded the DTS straight to a wav: Code:
eac3to input.dts output.wav -libav But this wav is not playable in any player, and when I try to encode it with NeroAacEnc.exe it gives me this error: Code:
ERROR: Invalid Channel Mask I'm just looking for as close of a lossless > 5.1 AAC solution as possible, and I would prefer to use the newest version of the Nero encoder. I am hesitant to encode from a low bitrate of 448kbps AC3 and would prefer to encode straight from the DTS source file. thanks |

edit: I do have a couple more questions - 1) Are most of you going with the eac3to default and removing Dynamic Range Compression? I assume this would be the most accurate reproduction of the original audio track, but in all honesty, it makes it hard to watch some movies because of the extreme difference in sound. 2) When listening to the final encoded AAC file (from 6.1 DTS) it is much quieter than when I encode to an AC3 file. I assume this is because of DirectShow filters. I wasn't able to find any volume settings in the ffdshow config to adjust volume for AAC audio. Does anyone know how to remedy this?

Hi,
A question about the -down16 command. In the past I have been saving my blu ray collection as MKV's with FLAC audio tracks, preserving the original bit depth. I'm now running a bit short on space and using the -down16 command gives me some real space savings. I remember that I've done some backups and eac3to says something along the lines of a 24 bit audio track really being 16 bit, and that the padding will be removed in a 2nd pass. Now the question! If I just put in the -down16 command will eac3to behave in the same way when it comes to 24 bit padded audio tracks and just remove the padding in a 2nd pass? Or does it blindly dither down to 16 bit without checking? |

I have one more quick question -
In your opinion, is buying the Arcsoft suite worth the money for the quality difference between it and regular LibAV (when encoding from DTS)? I've read that the newer versions of LibAV are just as good but I would like to hear some more input on the matter. And no I'm not asking which is best, just what you prefer. |

Libav don't decode DTS-HD.
BTW, you can use trial versions of ArcSoft to do the job. See this post http://forum.doom9.org/showthread.ph...77#post1398577

No errors or indications during the encoding process. I've tried encoding it in Windows 7 and XP, both with the same result. Is the Arcsoft decoder unable to to decode some 6.1 tracks? Nero and LibAV handle it fine but without the full information like you stated. |

(Long encoding time because I'm running another encoding project at 90% cpu)
Code:
eac3to v3.18 command line: eac3to.exe F:\Encode\BluRay\X3\BDMV\STREAM\input.dts F:\Encode\BluRay\X3\BDMV\STREAM\output.m4a -quality=0.40 ------------------------------------------------------------------------------ DTS Master Audio, 6.1 channels, 24 bits, 48khz (core: DTS-ES, 6.1 channels, 24 bits, 1509kbps, 48khz) NeroAacEnc doesn't support 6.1 encoding. Will double the 7th channel. Doubling 7th channel... Decoding with ArcSoft DTS Decoder... Remapping channels... Encoding AAC <0.40> with NeroAacEnc... The original audio track has a constant bit depth of 24 bits. The processed audio track has a constant bit depth of 24 bits. eac3to processing took 29 minutes, 42 seconds. Done. |
