Activity Forums Compression Techniques Compressing for SpotExpress delivery

  • Compressing for SpotExpress delivery

    Posted by Bryce Leverich on May 19, 2009 at 2:37 pm

    Hello,
    I was wondering if anyone out there delivers content via SpotExpress? My production department was recently tasked with going from tape delivery to electronic delivery via SpotExpress. I am having some problems getting a good image while maintaining their 300mb limit. Our uncompressed spots are :30 in length and roughly 420mb. I have tried the .H26 codec but the gamma loss is pretty noticeable to me. Does anyone have any suggestions on which codec to use? Any help would be greatly appreciated.

    Thanks

    It looks like they don’t provide any info either!

    I use DGFastchannel for spot delivery. Can you link to SpotExpress web page and/or PDF with their specs?

    You haven’t given a clue about their specs or your workflow so barring psychic powers it’s hard to venture much more than wild guesses.

    Thanks,
    SpotExpress needs the video in a QT container, so here are their QT accepted codecs:

    QuickTime Apple Animation
    QuickTime Apple BMP
    QuickTime Apple Cinepak
    QuickTime Apple Component Video
    QuickTime Apple DV/DVCPRO
    QuickTime Apple Graphics
    QuickTime Apple H.261
    QuickTime Apple Motion JPEG A
    QuickTime Apple Motion JPEG B
    QuickTime Apple MPEG-4
    QuickTime Apple Photo JPEG
    QuickTime Apple Planar RGB
    QuickTime Apple PNG
    QuickTime Apple TGA
    QuickTime Apple TIFF
    QuickTime Apple Video
    QuickTime Avid DNxHD
    QuickTime HDV
    QuickTime IMX
    QuickTime BlackMagic 10-bit
    QuickTime BlackMagic RGB 10-bit
    QuickTime DVCPro 50
    QuickTime DVCPro 100/HD
    QuickTime H.263
    QuickTime H.264
    QuickTime Intel Indeo Video 4.4
    QuickTime JPEG 2000
    QuickTime Omneon
    Spotexpress does not have it’s own website (strange I know, but according to tech support, it does not exist) but the mother company is VideoShip, https://videoship.com/

    They require 720×480 or 720×486, 16bit audio and a max file size of 300mb.

    I am using FCP export with QT conversion, but I also have Episode pro and Compressor.

    Found it. It would be most helpful if you would have provided this along with the proper name of the service.

    It’s SpotXPress, not SpotExpress.

    You are probably right. My bad. Crazy companies with their “X’s”. Thanks for putting up with me 🙂

    It seems they don’t have specs for slate and black as DG does. As you note .mov cuts a broad swath and they only have size limit rather than peak data rate ceiling.

    300MB is rather hefty.
    What’s your source codec in FCP timeline?
    You could probably deliver H.264 at something obscene like 50mbps and still be under 300MB for a 30 second spot.

    Interesting that they have Black Magic 10 Bit but not “old fashioned” 8 or 10 bit Uncompressed. Heck they even accept DVPro100/HD. It looks like they’ll accept many timeline codecs as is. It seems possible to do no compression at all in some cases.

    We shoot in DVPRO-HD, timeline is uncompressed 10-bit. I am exporting an h264 at 50mbps as we speak.

    H264 at 50mbps looked great… only problem is it took over 30 minutes to encode. With our deadlines and the amount of spots we put out in one day, we can’t encode that long.

    I am going to go ahead and try some other codecs, and try to figure this out via trial and error. I really appreciate your help!

    [Bryce Leverich] “it took over 30 minutes to encode”
    G5 with one core, MacMini with 1 core, MacPro 8 core with QMaster set to 4 instances?
    Time is a meaningless number without details.

    As a auto mechanic might say, “I can’t fix your vehicle on the phone. For all I know you’re riding a tricycle.”

    Multi Core Mac use QMaster.
    Try encoding on Episode using 2 Pass.

    You could go with the “old reliable” MPEG2 Program stream (They mention .mpg as acceptable)
