Nokia N95 Variable Frame-Rate

Thursday, January 19th, 2012

I came across some old videos I shot on a Nokia N95 and pulled these into Adobe Premiere.  However the individual video clips were each listed with a different framerate, hovering vaguely around 29 fps (27.08 up to 29.45).   Questions:

  • What does that even mean?
    • From web-search, it sounds like it’s an average, and N95 framerates within a given recording can vary wildly
      • e.g. between 6 and 38 fps.
  • How do various apps etc. handle such material?
    • YouTube:
      • In 2009 at least, it sounds like YouTube went for the minimum fps in any such clip.
    • Adobe Premiere
      • Seems to go for the average
        • I dragged a N95 clip on the “New Sequence” button and the resulting sequence had the clip’s average framerate.
      • Presumably just duplicates/drops frames as required to maintain the Sequence’s framerate.
    • GSpot (video analyzer):
      • For a clip reported by Adobe Premiere to be 28.81 fps, GSpot reported it to be 29.412 fps.
        • Misleading info from one or other or both…

Vodafone USB Modem Stick

Thursday, January 5th, 2012

I have a Vodafone USB Modem Stick (cell broadband dongle) which was obsolete even when I received it (free/gratuit).  Its design intention was you plugged it into a computer and, like some storage devices (e.g. memory sticks) the computer installed its driver software and you were ready to go.  In practice however it does not work either under Windows 7 or Mac OS Snow Leopard.  Some things report failure to install and/or the machine crashes if yoy try to boot up with the dongle already plugged in, or if plugged in after restart, a message requests further restart.  There is no way out into a state where it can perform its main function.

The dongle is a Vodafone K3765, which I have heard is actually an Icon 411 made by Option .  It will allegedly run on Windows 7 but not pay-as-you-go.

I wonder if a newer version of the dongle (and any associated application software or drivers) is available.  Then again, what’s the point if I can use the phone, especially as it’s less hassle all round (fewer technical complexities and hence possible issues, simpler purchasing all-in-one contract including data). Maybe I should just get it crushed?
