Can *any* PC play these videos smoothly?

    A big step up, for sure, and Apple in particular has been supporting it
    for quite a long time.
    A modest expense:

    Smarty and his wife go to the pharmacy to pick up his prescription.
    Seeing the $10 per pill price, Smarty was astonished - but his wife had
    a different opinion - "Oh, $30 a year ain't too bad".

    [...about image motion detail softness...]
    The softness is likely caused by the data rate acceptable
    to the camera before breakup. To check this, put some
    original footage shot by the camera at the highest
    quality possible on the Vegas timeline and move
    frame-by-frame through some higher motion parts by
    holding down the "Alt" key and using the "Left" and
    "Right" arrows. You will see that the frames themselves
    are soft, not as a result of the playback gear...
    Not unless you want to be "trapped" in a very low quality
    format for your edits... Try 35 or 50Mbps MP4 for your
    edit archive format, converting that to anything you want
    later...
    It's relatively cheap here in similar-looking central NYS,
    thank goodness!8^) But for 'SPENSIVE, try some of the
    more sought-after areas of California, etc. 8^(
    Yes...

  3. Or you could use the format your original was shot in, as you
    told us about in another post, "AVI HD 1080 50i YUV =, or AVCHD
    1080x1920x50i =".

    All play on my Internet computer, an AMD Athlon 64, 2.04 GHz, with 1 GB Ram
    and a pretty pedestrian video card. I didn't bother to try playing the
    files on my i7 AV computer.

    That's an interesting exercise.

    Referring to the file jetprop1.mts (80MB) at

    http://peter2000.gotdns.com/jetprop

    that is the original ex-cam file, in the highest "MXP" setting (24
    mbits/sec supposedly).

    Opening it in Vegas, and stepping through, I see very minimal blurring
    on individual frames.

    The cam was set to shutter priority, 1/120sec (for reasons connected
    with in-flight filming, where 1/120 or slower stops the propeller
    effects completely).

    Also, connecting the cam directly to my Sony 1080P TV, the footage
    looks perfect.

    So the blurring must be happening later on.

    Unfortunately I have no way to play the original files, after
    transferring them from the camera, because of obvious video
    performance issues *somewhere*, at *that* frame size/rate.
    I wasn't suggesting using 1mbps for archiving :)

    How to archive this stuff is another whole big question. At the
    highest setting the camera is producing ~ 10GB per hour, which is
    slightly less than the old HC1E DV/HD cam was generating in CBR mpeg2
    (~11-12GB/hr). I have just transferred ~ 40 of those tapes to HD and
    archived them to DLT tape, so I can deal with some more :)

    The 1mbps is purely for putting aviation related videos on my website
    peter2000.co.uk. The Iphone4 preset in Handbrake seems OK; the Church
    of Jobs "media players" are very popular in Europe.

    I still need to find a format for exporting from Vegas to Handbrake.
    I've tried a few which all seem to product the same result in the end;
    but produce wildly different filesizes (from 50MB to 2GB for the above
    clip, despite all being 1920x1080).
    N California (Yosemite etc) looks very similar to much of N Europe.

    Indeed, see my note about one producing 2GB and the other producing
    50MB, with there being no visible (to me) difference at the final
    output.
