The video isn't too bad if you watch full screen and crank it up to 1080 in the settings. Not sure why you stretched it out - it looks better to me at twice that speed.

I thought it was set at 1080, I was sure I selected that setting but this is only a trial run, I need to get used to the video setup with the camera.  In the past I have done T-L by taking JPEGs every 15 or 20 seconds then combining them into a video in photoshop but the process is messy, convoluted and very time consuming.  I have thousands of images watching leaf buds bursting taken at 30 minute intervals over weeks. With the D800 all you have to do is make some settings in the camera and walk away.  The result is a single video file which is ready to view, easy peasy!  I love it, can't wait to do more...

I stretched the video because there is so much happening as the channels fill and envelop the sandbanks it's impossible to follow the action from about 3½ Hrs compressed into 22.4 seconds.  The main reason for the video is so people can see how the channels fill and how easy it is to get cut off very quickly, far quicker than you can run.  Once the bore starts to flow things happen very quickly.  It's very interesting to see how gently the water rises until a certain point when it starts to surge in.  I don't think the tide graphs accurately reflect the ramp profile of the tidal rise, it's not linear, there is a very distinct surge.  The Inshore Rescue's focus is on avoiding people getting into trouble on the sands in the first place.
