For Aften you need rev449 at least, because with 2h21m 6 channnls you need "-readtoeof 1" not supported by v0.06. |

hi guys, i need a little help. i have the newest behappy, and i try to convert an ac3 file from pal to ntsc 6ch wav, its 2h24min long.. the problem is this: i open the wav with any prog, it shows 2:04:17.. in delaycut in the info actually the correct length is shown (2h31min), but in the target file the 2:04:17 again.. what can be the problem? the wav is actually around 4,8gig.. any suggestion? is it possible at all to convert such a long track with behappy?
thanks update: well, i actually managed to get the correct length, but only if i load in the six separate mono wavs and stretch those.. strange.. but the ntsc track isnt good, it goes out of sync at the end, but its correct in the beginning.. with adobe audition i get with time stretch perfect timing.. :s Last edited by tauka; 25th April 2007 at 04:45. |

Edit: see also this link Don't worry Aften can encode this long track with the parameter: -readtoeof 1. If you want encode to aac, NeroAacEnc also support long files with -ignorelength parameter. Quote:

I'm trying to convert AC3 to AAC 6ch. The source is a DVB stream (live concert). I don't know if it has DRC. How can i figure that out (metadata)?
If i use 'NicAC3Source (DRC)' what compression rate will be used? Most standalone dvd players have 3 profiles (low, med, high). |

I think its not a different compressor. It is intended by Dolby to have impact on DRC like this to optimize volume for different environments (small speakers (high compression/flat sound), big speakers (no compression/full dynamic)). That's the way 'dialogue normalization' works. There are official dolby whitepapers linked in the faq sticky. I think i read it there...
My settop dvd player has some static values (low, med, high) for DRC that do the same what Ac3Filter does (i think) so this must be intended by dolby. The second screenshot i posted above holds some metadata for 'line mode profile'. These could be preset values for that additional compression and may be used by Nic's DRC method. But i'm not sure on that... Edit: solved... neroaacenc.exe has to be moved to 'encoder' folder. Beside of that BeHappy doesn't work with my scenario. I use BeHappy with aac update. NicAc3Source(DRC) to load my Ac3 file. If i output as avs script it works fine with mpc. If i enqueue and start the batch process following error msg appears in the log: Translation: Das System kann die angegebene Datei nicht finden = File not found Code:
Starting job ggg.ac3->ggg.mp4 Found Audio Stream Channels=2, BitsPerSample=32 float, SampleRate=48000Hz encoder\neroAacEnc.exe -ignorelength -q 0.3 -if - -of "F:\ggg.mp4" Error: System.ApplicationException: Can't start encoder: Das System kann die angegebene Datei nicht finden ---> System.ComponentModel.Win32Exception: Das System kann die angegebene Datei nicht finden bei System.Diagnostics.Process.StartWithCreateProcess(ProcessStartInfo startInfo) bei System.Diagnostics.Process.Start() bei BeHappy.Encoder.createEncoderProcess(AviSynthClip x) --- Ende der internen Ausnahmestapelüberwachung --- bei BeHappy.Encoder.createEncoderProcess(AviSynthClip x) bei BeHappy.Encoder.encode() Last edited by NoX1911; 14th May 2007 at 00:43. |

I've noticed chages in OggVorbisEncoder.cs and CodingTechnologiesAAC.cs, please document them. Maybe the mod should have it's own repository, something like a project page on sf.net. |

In CodingTechnologiesAAC.cs only size parameters to avoid the problem in post #568.
In OggVorbisEncoder.cs size parameters and: Code:
if (Quality <= 4) ApproximateBitrate = (double)(Quality + 2)*16 + 32; if ((Quality > 4) && (Quality <= 8)) ApproximateBitrate = (double)(Quality - 4) * 32 + 128; if (Quality > 8 && Quality <= 9) ApproximateBitrate = (double)(Quality - 8) * 64 + 256; if (Quality > 9) ApproximateBitrate = (double)((Quality - 9)) * 179.8 + 320; rbtnVBR.Text = string.Format("Variable Bitrate Q={0} approximate {1} kbs", Quality,ApproximateBitrate); |

CodingTechnologiesAAC.cs: I resized and changed position of component to avoid the problem in post #568 OggVorbisEncoder.cs: added "ApproximateBitrate" value. Quote:
It is quite right if I use oggenc2 while oggenc show a lower bitrate. I'm using MediaInfo to observer information of media file This feature come from OggDropXPd Link to download oggenc2 ( I prefer oggdropXPd V.1.8.9 using libVorbis v1.1.2 with IMPULSE_TRIGGER_PROFILE Option) and OggDropXP http://www.rarewares.org/ogg.html Good luck! |
