the only criticism I have on that video rob is the contrast levels and heat haze , a Cpl filter might help or perhaps negative exposure compensation , I would take a few test shots next time to try and raise the contrast levels.. weather looking good for this weekends tides to

Thanks for looking Jeff, the video is perfect at this end, I think it's the You Tube video compression which has ****ed it up. I may have used the wrong settings uploading it, I don't know, some of the video terminology/jargon is double Dutch to me. I am planning another this next weekend, the weather forecast is good and the tide range is greater, low tide down to 0.5M and high tide up to 10.2M, last week was just a trial run really. I need to experiment with the video settings in the D800 because I know they weren't optimal. I had intended to just take a ton of JPEGs then combine them in Ps into a video, which I have done before but since the D800 can do it in camera so neatly I thought I would give it a whirl. I will also use the extra battery compartment which came with the camera as a way of doubling the battery capacity. I need a portable external power source but it will have to wait for now. I may run the D300S and use a longer lens to make short clips of specific areas of the estuary. I also want to edit in some clips of the currents and whirlpools around the pier. They are seriously dangerous and quite spectacular. What with getting up early for tides and staying up late to photograph stars I don't see many opportunities for sleep! But you can't miss good weather for either.

Sorry Chris, this slipped under my radar. I have had another session today, spent the morning on Askam Pier, nothing glamorous, just many thousands of tons of slag from the old steelworks, which was demolished in the 1930's flourished in the late 1800's. The pier forms a barrier nearly a mile long out into the estuary, like a giant breakwater. The tide has to go round it and the currents are really fierce, at the far end it is about 2 Metres above normal high tides.   I wanted to video a full tide coming in, close up, from the initial bore to slack water at high tide. This morning a recorded it for a bit over three hours with the D800 and the D3 taking JPEG time lapse at 5 second intervals. Unfortunately the conditions seemed to have prevented the severe whirlpools forming today, but todays video shows even bigger ones off the end of the pier. The D800 was wonderful, I set the interval and duration and at the end it finished and the resulting file is an MPEG4 I think, no sound of course Not sure of the resolution. The D3 doesn't 'do' video so I set it to work taking JPEGs, 1700 of them! I have just finished outputting the MPEG4 file a few minuets ago, it has taken me most of the afternoon, I don't do it very often, so had to refresh my memory on how to do it in Photoshop. I output it at 1920p resolution I think at 24.xxx frames per second. The previous video from the D800 was the basis for the you tube video I uploaded. I will have to check out what the settings were but when I played it before uploading it it was perfect. I am sure the compression and whatever Google do with it for publication, played havoc with the quality. Once I have recovered I will upload todays video, I will try to break it down a bit, it totals over 2.5 minutes for three hours of recording on two cameras.

Well if you let me know the file extension and filesize I can set the forum to allow you to attach the file so people can play it locally without having to go via Utube

Thank you Chris, below is the 'get info' screen. That is for about two minutes of video but I plan to edit it down a lot. I was shooting with two cameras simultaneously almost back to back. I hope to interlace the two clips when I get the time/energy (I do have the time right now but not the energy!). I anticipate at least half of the video will be cut out, maybe still frames added to dwell on some aspect perhaps with a touch of Ken Burns thrown in. I find Video editing tedious and very time consuming. Perhaps if you can you could advise me what size and other settings might be optimal for this.

OK - you can try attaching that file to a post. I might need to tweak some of the server settings if it takes to long and times out ideally keep the file as small as possible, consistent with the desired quality.

We agreed when we set up the forum that video would be uploaded to YouTube as video would soon eat our disk space. Since YT are happy to host for free it makes sense to keep video there.

Perhaps a better host like Vimeo (or some other) might be better? I do have a Vimeo account, or I did. You Tube is Google (I think) they don't do ANYTHING for free. I agree we need to take advantage of 'free' hosting for video but the quality hit on my last upload was really bad. It may have been because of my choice of size, format or settings, I don't know but if that's the standard I am going to get from You Tube I won't bother, video has always been very marginal for me, the amount of work needed for a few seconds video is not worth the effort. Using the D800 time-lapse movie feature makes it a dream, rather than thousands of JPEGs to process, which even with several SSD's and a fast processor is still a drag.
