    What are you talking about? H.264 (aka AVC) is an open standard. Apple is not the only one who implents this standard. In fact, Apple is quite slow. Here's a short list of available encoders:
    Sorenson Squeeze 4, MainConcept H.264 Encoder, Nero Digital AVC, Hdot264, x264, etc....

    And when you look how bad the quality of Apple's MPEG-4 ASP is (compared to XviD, DivX,...), I wouldn't bet that Apple AVC will be so great either.
    If you want to encode on Mac I guess that Sorenson Squeeze 4 is currently the best sollution. According to the latest codec comparison on Doom9.net NeroDigital AVC is the best codec (Sorenson was not tested).

  2. Re:I don't even watch ads on tv by millette · · Score: 1 · on Bringing Interruption-Based Ads To the Web
    Once the episode is recorded I fire up MainActor, snip out the commercials and splice the various parts together [...]

    While I'm not terribly familiar with MainActor (after all, I just read its product description), it doesn't seem to make this editing a batch process, which would become rather tedious after a while.

    Not everyone is interested in taking the time to edit out commercials of course, but for those programs one really enjoys, viewing the show without interruption enhances the experience immensly and is well worth waiting a day or so to watch [...]

    Exactly. So I'm thinking, why not bypass the editing altogether and let dvgrab take care of it? Not that I'm more familiar with it (don't you love moderation?)... but I'm guessing it's gpl, whereas MainActor is a commercial app, thus difficult to modify. So dvgrab could be patched - but that might not even be necessary - to either stop recording at specific intervals, for specific amounts of time, or check for something like db level (is it true the volume generally goes up for commercials?).

    Come to think of it, this is pretty off-topic. Sorry :)
  3. Re:while this is nice .. by Dr.+Manhattan · · Score: 2 · on Review of the Matrox G450 For Linux
    Well, the cameras are kinda pricey, but Firewire/i-Link/IEEE1394 video is pretty cool. The native DV standard is 720x480@29.97fps(NTSC) or 720x560@25fps (I think) (PAL).

    I've got a Sony TRV-310 (~US$800 last Christmas) and and an ADS Pyro Firewire card (US$70 a couple months ago). The nice thing about the camera is it can play and digitize even old 8mm camcorder tapes.

    See the DVgrab links page for info on exactly what software and hardware are needed/available.

    There's one open-source video editing app (Broadcast2000) and one commercial (MainActor) for Linux that I know of.

    Note that such camcorders store and transmit using the DV standard, which is compressed to ~3.7MB/sec. There are also raw video cameras available, though I don't know if they are supported yet. For scientific work you may need a raw camera, for personal or broadcast work DV is ample.
