eac3to doesn't seem to handle TrueHD frame changes at the moment. A sample file I have switches from 6 channels to 2 channels within the first few hundred KB, but when it does, eac3to returns "a03 libav Restart header sync incorrect (got 0x14be)" then fails while ffmpeg decodes it properly. Any chance supporting this?

Out of curiosity: Isn't the effect similiar to avisynth's AssumeFPS(xx) vs ChangeFPS(yy)?
I mean -24.000 would set the new audio playback speed and change the original duration, while -changeTo24.000 would keep the original duration? |

Hi guys, sorry if this may have been brought up before, but I was wondering if it is possible to do either slowdown or speedup whilst preserving the pitch?
For example: '23.796 to 25' pitch preserving/correction? and vice-versa with different framerates? |

dvd video have 10619286 x 23.976 = 254608 frames bd video have 10631458 x 24 = 255155 frames The bd video have 547 more frames (~23 seconds) than dvd video. Isn't the same video and you need a big edit to use the audio.

I noticed the difference in runtime, what is weird is the main movie is the same for both Blu-ray and DVD. There is difference in the title and credits of the movie in terms of additional information. I thought adding suitable delay to sync the audio should work. For some reason it just goes out of sync progressively. When I compare the runtimes of the converted audio from the original audio the original audio is ~1.001 * converted audio runtime. I guess I need to see what else is different to fix it.

Some defaults can work, for instance: -slowdown is equivalent to -25.000 -changeTo23.976 -speedup is equivalent to -23.976 -changeTo25.000 But I like always put the fps pair and don't assume any fps for audio. The fps equivalent parameter for audio is samplerate: 48 KHz means 48000 audio samples per second, like 24 fps means 24 video frames per second. Quote:

No problem with end credits the audio can be short than video.

I'm having an issue with a DTS-HD MA 6.1 audio track from Ghost in the Shell 2: Innocence's Absolute Edition. The disc has a TrueHD 6.1 and a DTS-HD MA 6.1 track, and I can compress the TrueHD to FLAC, extract the DD5.1-EX core and also extract the DTS-ES 6.1 core, but when I compress the DTS-MA HD track to FLAC, it ends up being around 2.5 GB (vs. the DTS-MA HD's 1.8 GB) and the output file is also stretched somewhat. The original runtime of the film is 1hr 39m, however the FLAC of the DTS track reports it's 1hr 53m long, and during playback the audio is there, but it's distorted and stretched. No warnings or errors are reported by eac3to, and again all other tracks playback fine.

Hi all
Quick question.. What is the command line to upconvert a 6.1 TrueHD track to 7.1 FLAC (with centre rear doubled to L back and R back)? There's a trilogy coming out soon (finally..) with 6.1 sound |

But this command does work incorrect, you need to add -0,1,2,3,5,6,4: eac3to input output -double7 -0,1,2,3,5,6,4 |

Edit: Something I just noticed though, eac3to reports the track as being 16-bit however the bits aren't stripped in the second pass like they are for the TrueHD track. I'm testing decoding with Sonic Audio Decoder now to see if that works, although I'd rather not use it. Edit 2: Sonic decoded it fine, same exact bitrate as the TrueHD (figured). Plays back fine and has the correct length. Still don't know why ArcSoft is having a problem with it. Last edited by Chouonsoku; 8th April 2011 at 01:02. |
