It's not so easy if you have to consider everything, not just your little corner of the world. It much reminds me of administrative decisions on this board.. people might not understand because they do not have to consider so many aspects of the same problem. It is much easier just being a normal user and care about your set at the table instead of the whole table.

either way guys... aac audio doesn't go in every case so it's a moot point..

IMO real-world settings are nice. But not nice enough to be worth causing you a major headache. (Plus, all options give an idea of which codecs overshoot/undershoot, which is the part we are likely to remember anyway.) So I would say go with 3.
Really looking forward to the main round!

In-fact.... I'm hoping to convince a hardware player manufacturer to upgrade their player firmware so it can recognise MPEG-4 with 6Ch AAC within .AVI, along with MPEG-2 with 6Ch AAC within .TS Cheers

I voted 1, because that's what I do. I generally use AVI because it keeps things simple.

The container is pretty much part of the codec, as far as I'm concerned. If I'm making a Nero AVC, it's going into the mp4 container. If I'm using xvid with mp3, it's going into an avi. The same reasoning applies to most video codecs.
If I'm using Nero AVC, I'm almost certainly using a lower audio bitrate than 128Kb/s (HE AAC). And, if I'm using Xvid, I just might be using a much higher bitrate than 128Kb/s (the original AC3 stream). If I'm using the Ogm container, I'll be using Ogg Vorbis audio which will give me a bit savings greater than the Ogg container itself over avi. But, adding these factors into a codec comparison is impractical. So, I'm voting for dump the audio but consider the container. #2, I always vote for the loser, 'cause I vote 3rd party. I can mentally factor in the effects of audio on bits I'll have left for video. I know if I go with HE AAC or Ogg over MP3, I can give the video more bits. And, if I keep the AC3 stream, the video will get less bits. Last edited by Doobie; 19th December 2005 at 16:50. |

well, you know well enough why Matroska will never be an option for me, so please don't start. It's the same every year.

I like doom9's comparisons because it is more realistic and holistic. That is the point where it differs to MSU comparisons for example (despite the quality measure) that are pure cientifical. A codec is not only it self, but all the things around it. For example: VC-1 can be faster and have an greater quality than Xvid (hipotetical situation, not necessarily real), but Xvid is still a better codec than VC-1, because it is free, is based in an open-standart, it is more suported in edition tools, players, hardware, etc, etc....
It is not good take the things isolated, so I voted keep everything as it is, though 3 option would not be so bad. |

While I didn't had dvdrw (shame on me for waiting so long) I did all my movies backups with x264/ac3 or mp3 in avi files, becose they are more supported and easy to handle. Yes I do know mp4/others might be more effective, but hey I was lazy to get dvdrw drive, and you expect me to change entire container?
To the topic issue : yes, my backups were being 700 or 1400 mb, so yes, container overhead is important - since its too often "part of codec itself". While I don't want to mix in differect audio codecs, since it will really mess things up. P.S: Are going to see x264 in next round? Imo its one of the best out there. (If not THE BEST) P.S.S: Can't wait for AVC/AAC 7.1 on HDDVD-R DL media |

I think Option 3 - encoding just video within the native container - is the best option. Audio isn't the focus of this codec comparison so there's no reason for it to be included. Right now it's serving only as a placeholder. Although ultimately achieving a perfect file size matters, in a video codec shootout it's the rate control accuracy of the video codec that should be judged. Packet and container overhead do matter in the end, but ultimately they're not a property of the video codec.
