This does not mean too much, except the fact that Nero ABR scored little bit better than CT CBR, but not better enough to be called statistically significant. If you wish to test Nero CBR vs CT CBR - please go on But I personally do not see too much point in such test - I dunno who would use inferior mode (CBR) when there is better mode available (ABR) - except for streaming, of course. |

Hi I just downloaded updated encoder, could you explain why in package are 5 exes? 3 in win32 folder and 2 in root. what is diffrent in those 2 in root? are they there by accident?

- What bit-rate mode are you using? (abr/cbr/vbr/2-pass) If you are using anything else than CBR expect the bit rate to change with the psychoacoustic properties of the signal - if your 'boost' operation increased the volume of the file, it could also mean than some parts that were judged to be below the threshold of hearing (and, hence, not coded) are now coded. - CT is a Constant Bit Rate encoder - you can encode digital silence and you will still get the same size - if you want to use the same mode in Nero - use the -cbr switch, and the results are going to be exactly the same. @GmorG McRoth, it seems exes were copied to two locations, they are the same - we'll replace this asap. |

I do a same thing with nero using -cbr switch as you recommend and i get 97MB. Boost applyed is +4.5dB. I aslo tryed with 2pass mode. his downed file size to 93MB |

Yes - elementary stream should be fully compatible with the definition of 'constant bit rate' in ISO/14496-3 criteria.
BUT - you have to extract to headerless or ADIF aac elementary stream - if you extract it to ADTS AAC, extraction tool with add additional overhead of 7 bytes to each frame - which can be quite a lot if we are talking about a movie - since there can be e.g. 40 frames per second |

I think that mp4creator from MPEG4IP has the option to extract to headerless AAC tracks - there you can get the exact bit-rate of AAC stream, without any overhead.
But I am not sure why do you need that for? Headerless AAC is almost useless. |

@Dimzon,
I just forwarded this message to the developers working on the frontend. I can only answer for ADTS AAC - and the answer is, no. We do not plan to support ADTS AAC as many of the encoder features are impossible with this outdated transport multiplex format. |

I can't ever remember having sync issues with my AAC streams... and I've de-muxed them from MP4 files containing ASP video and re-muxed them into MP4 files containg AVC video. I've even generated 6Ch AAC streams (from the same AC3 source) using different encoders (Nero, FAAC, WinAMP) and muxed them into the same MP4 file (with video), so I can flick thru' them to compare any differences... I do it all now with YAMB (before that it was mp4UI) and they are always in sync

btw. Ivan why 2pass not work with stdin. This is powerfull option for long encodings can't be used for movies. I am not crazy to convert ac3->5.1wav btw. i do some other test with 5.1 CBR encoding en i get good quality, with 2pass i get litle bit better quality than CT Last edited by shon3i; 5th May 2006 at 11:14. |
