Rendering a speeded up movie

    No idea if anybody still reads this forum but I did this
    (1280x720x25P)
    as a "proof of concept" where a long flying movie (4+ hrs) is speeded
    up 16x enroute, while running a "correct time" counter in the corner.

    On a dual-core Intel it took about a week to render, with the original
    ~30GB ex-camera material taking ~25hrs to render with the time
    counter. The first speed drop (4x - the biggest that Vegas allows)
    took another 25hrs (Vegas takes a long time to apparently interpolate
    the frames, but the result is quite good) and the next ones were
    quicker because the source material was down to < 1hr then.

    The basic image quality is good, despite the multiple renders and is
    way above most of the webcam type stuff people are playing with.

    There is a way of doing all the different edits and then rendering
    everything in one step, and there may even be a way of keeping the
    "original time" counter in there somehow, but I did not find out any
    way to do that.

    I didn't think of doing the sound track. I have an in-headset mike for
    that, with a little "pro" preamp, and it works well. But really for a
    totally hands-off job I need an aircraft headset jack plug to
    camcorder converter cable. I wonder if anybody makes one off the shelf
    that actually works?
