    "(All of the MPEG codecs we talk about, btw, will have an associated layer, since the video section is only part of the full standard, which includes audio and other stuff. MPEG-1 Layer 3, you probably know, is MP3.) "

    You've got the wrong terminology there buddy. Part 2 of the MPEG-1 specification is indeed for video and part 3 is for audio, but part 3 and layer 3 are not the same. The MPEG-1 Part 3 audio specification includes three layers of audio formats, layers 1, 2 and 3 – each one building upon the other. Thus, layer 3 includes all the elements of layers 1 and 2 plus some new stuff. This is actually a bit inefficient because of the layering, but it was ultimately decided to implement the specification in this manner to allow for the greatest compatibility. The OGG audio codec is actually very similar to MP3, just without the layer 1 and 2 compatibility – hence it is marginally better than MP3.

    @OrenDolabella: No they're not. The layer/part mixup was an editing error. I swear I had it right originally!

    All the Blu-ray AVC, VC-1, and MPEG-2 codecs are wrapped inside MPEG-2 transport stream containers (.m2ts). The HDDVD VC-1 and AVC codes were wrapped inside .EVO containers.

    I just want to find a free converter from AVI to MP4 since AVIs are too big to e mail and I am too lazy to look.

    Can we please stop using the mkv container? It's the most resource hungry format I've ever encountered. Thus, it ends up taking ~100min to convert an hour of HD video to play on the Apple TV. And Boxes can't even handle mkv files.

    @teexcue:
    MKV has nothing to do with your encoding/transcoding times. It's just a wrapper, or container. What governs your computational time is what's inside that wrapper. Admittedly, most MKV files on the web contain heavily compressed H264 video streams, which are very resource-intensive. But, that's not MKV's fault. If the MKV file were to contain an equivalently long and resolutioned MPEG-2 stream, it would be much faster to convert.

    @xsecretfiles2: I love my .mkv files, because that means I can turn off those annoying subtitles without having to have a separate file.


    Also, they are usually at a better quality than those shabby .avi's (of course, all my .mkv's usually say 720p so that's probably why xD)


    Oh, also. VLC laughs at those codecs! In a smug, french way. No-ho-ho-ho!

    @Eruanno: How would a container format affect quality? Did you not read the article?
