    I've gotten the QT7 encodes using Xiph tools to produce a decent quality ogg file.  I've been able to open the ogg in Firefox on my Macbook Pro as well as an android device.  So the basic problem of simply getting something into the open format is solved for me.

     

    However, the webm format seems unstable within QT, delivering poor quality, and at one point a crash.  Ogg has worked reliably in several tests.

     

    Also, I've been unable to configure a solid preset for this in Compressor.  It seems as though the wrapper may be as much of an issue as the codec.  I've installed other components (DNxHD and X264) and gotten those transcodes to work in Compressor.  But I can't seem to get it right for ogg/vorbis.  Nor have I been able to successfully configure this in Adobe Media Encoder CS4.

     

    So, I've got a decent QT solution; but not what I really want.  I'd like to simply be able to render directly to these in Compressor (3 & 4) and/or Adobe Media Encoder.  If anyone has better success configuring Compressor, I'd love to hear about it.

    Hi

    I too am looking at a solution for this please.

     

     

    h.264/MP4

    Theora/Ogg

    VP8/WebM

    I use .ogv every day as a deliverable format.

    It's not the most useful format as almost no-one recognizes it, but contrary to what one person has said, it is not proprietary, quite the opposite - it and webm are the only open source standards out there.

     

    My workflow is as follows:

    • cut in FCP
    • export .mp4 using h.264 encoding (make sure you also click Video Options and select the "Baseline" profile, not "Main" - this will ensure your video works across all browsers/iOS devices).
    • If you want really sharp quality, kick up the data rate to something like 3600 kbits/sec, but this will make your file larger.
    • Once your video exports, go to firefogg.org, drop the file in, choose webm or ogv as your export setting, and go man, go.
    • NOTE: if you want "batch" processing, you can fake it by opening multiple browser tabs and starting several Firefogg processes at a time. The browser might crash, but I've had pretty good luck so far.

     

    Good luck!

    PS - Compressor is a proprietary Apple product that uses proprietary codecs (mostly Apple's), so don't count on ever being able to make a setting or droplet out of ogg or webm.

    I couldn't even get Compressor to use a "Baseline" profile mp4 with h.264 encoding - I have to do it in FCP!

    I'm afraid this isnt correct.

    .mp4 is NOT compatible across all browers and iOS devices.

    The only sure way is to convert to all 3 formats

     

    h.264/MP4

    Theora/Ogg

    VP8/WebM

    @ shippo_uk:

     

    I'm afraid you're taking what I wrote out of context. For certain devices that can play .mp4, what I said IS correct. (http://diveintohtml5.info/video.html#what-works). This is mostly for mobile devices.

     

    For everything else, you'd need an ogv and a webm, which is the next step I documented above.

    This guy, Greg, this is the one.  Very smooth, easy, good quality ogg and webm using Quicktime.

    To compress and convert file to OGV and WebM, You can find the guide in Google. There are many compressor there. Hope you can get one.
