davegee Posted April 11, 2012 Report Share Posted April 11, 2012 It may (or may not) be relevant that Peter was initially experiencing problems with the files out of his D300s.These files are AVI? (not MOV).DG Quote Link to comment Share on other sites More sharing options...
fh1805 Posted April 11, 2012 Report Share Posted April 11, 2012 Dave,My problems are documented in a different topic. The two topics may be related and may have some common aspects and, possibly, end up having a common solution. But lets keep this topic for D7000 issues and my original topic for the D300s issues.regards,Peter Quote Link to comment Share on other sites More sharing options...
RobertAlbright Posted April 11, 2012 Report Share Posted April 11, 2012 Hi RobertHave you tried speccing your own with http://www.pcspecialist.co.uk/, I went this route with my last LT a couple of months ago.Regards EricYachtsman1.Thanks, Eric. The prices look good. I will investigate further.Robert Quote Link to comment Share on other sites More sharing options...
Guest Yachtsman1 Posted April 11, 2012 Report Share Posted April 11, 2012 Hi RobertIf you do go that route, be sure to include the "retun to base free" insurance, it's only £12 extra for 12 months cover. They also have a forum, which can be useful for checking your spec'Regards EricYachtsman1. Quote Link to comment Share on other sites More sharing options...
Conflow Posted April 11, 2012 Report Share Posted April 11, 2012 Hi Brian,The only problem I have with understanding the issue he is having is that when he puts his D7000 original MOV in PTE it plays jerky on his two systems. When David played SG's MOV on David's system it played perfectly.When I put my original D7000 MOV in PTE it plays perfectly smooth and likewise for several others who are using D7000 videos. Assuming SG has the same software as everyone else from Nikon including any necessary codecs, etc., doesn't this then indicate some difference in "hardware" between his system and others?Best regards,LinHi Lin,You wrote..."The problem I have with understanding the issue he is having is that when he puts his D7000 original MOV in PTE it plays jerky on his two systems. When David played SG's MOV on David's system it played perfectly"...Yes thats what 'fooled' me in the first instance ~ then he uploaded his 2 Mov-Samples which seem to be the original Mov's from his Camera. I ran those in 2 Media-Players and in both instances 640x424.Mov worked perfectly but the 1920x1080.Mov showed signs of breaking up (running jerky). I done some Maths on the HD-Mov and then analyzed it with the GSpot-Analyzer and sure enough the File was on the cusp of 'breakup' although the control-binaries were O.K. It should have worked ??The Analyzer and the Maths revealed the following:-SG done a complete 360*Scan with his Camera giving 354.Frames in 14.76 Secs = 41.66.mS/Frame but when one considers that 24 Frames per/sec = 41.66.mS/Frame then "bingo" it becomes obvious that the Camera had barely resolved 1.HD-Frame before the next was on the Mat.This will always produce 'vision-smear' and a degree of pixellation and 'cogging' on the Key-Frames which I saw in both Media-Players but as the apple-binaries seemed O.K ~ I decided to convert the Mov into an (uncompressed) Avi.The proof of that is shown in the Avi-File which I posted ~ it runs properly.The reason that the 640x424.Mov worked was simply because the Camera was less 'loaded' compared to the HD-1920x1080 loading and when the HD-File went over into PTE the proverbial hit the fan because PTE could not resolve the 'HD-Cogging' on the keyframes.There could be another explaination for this but in my opinion the resolved-data was fairly conclusive but at least one lesson must be learnt:-"Never Pan faster than the Camera can resolve"...Brian.Data-attached Quote Link to comment Share on other sites More sharing options...
fh1805 Posted April 11, 2012 Report Share Posted April 11, 2012 "Never Pan faster than the Camera can resolve"...Brian,Could you please give a simple formula that will tell us how to calculate the "safe" Pan rate?Thanks in anticipation,Peter Quote Link to comment Share on other sites More sharing options...
smokinggoldfish Posted April 11, 2012 Author Report Share Posted April 11, 2012 Wow, I never realised that this subject was so complicated. But I would like to restate some facts about my problem. Let's stick to the clips of my hand moving in front of the filing cabinet. These were shot with the camera on a tripod so there is none of the complication from panning. The clips loaded to dropbox (see above) were:DSC_2541.MOV this is HD i.e. 1920 by 1080 at 24 fps. Actually reading the camera manual the frame rate is really 23.976.DSC_2542.MOV this is low res 640 by 424 at 25 fps. The manual does not qualify this rate so I assume it is the real one.Both files play OK in Windows Media Player (WPM) straight from the camera, on my desktop PC. Because of the speed with which my hand is moving there is some blurring, but it is not jerky.When I put the files in to PTE and preview (full screen or windowed) the HD clip is very jerky with only a small proportion of the frames appearing, while the low res one plays OK.If I convert the files to the .converted.avi as suggested by PTE then the HD is a bit better but still not nearly good enough. More frames appear, but there are some pixellated artefacts appearing which weren't there before. The low res clip is still good.The crux of the problem seems to be that PTE cannot do as good a job of showing the HD clip as WMP, which is disappointing.I hope this clarifies my problem, and therefore helps diagnosis and remedy!sg Quote Link to comment Share on other sites More sharing options...
Guest Yachtsman1 Posted April 11, 2012 Report Share Posted April 11, 2012 The quick answer to this IMO, is those were ad hoc clips that didn't compare to what you would normally use the camera for. Take it outside on a tripod an shoot the traffic passing by, then come back and post the results.Yachtsman1. Quote Link to comment Share on other sites More sharing options...

nobeefstu Posted April 11, 2012 Report Share Posted April 11, 2012 smokinggoldfish,A simple question to begin sorting out your Direct X/video issue:Upon review of your PC/Video specs image posted, I see you are running Direct X10. Being that you are running Windows 7 and the AMD HD 6530D ... does your system/hardware not support Direct X11 for some reason ? From what I have read elsewhere ... the AMD HD 6530D supports Direct X11 drivers. See attachmentIf your system supports Direct X11 ... I would certainly recommend to install them and begin your tests again.*XP supports Direct X9*Vista supports Direct X10/11 (depending on service pack) Quote Link to comment Share on other sites More sharing options...
Conflow Posted April 12, 2012 Report Share Posted April 12, 2012 Brian,Could you please give a simple formula that will tell us how to calculate the "safe" Pan rate?Thanks in anticipation,PeterHi Peter,I shall get back to you about Panning ~ Thats really a matter of 'Technique' rather than a matterof Calculations. There are 'Look-up Tables' available but they are complex depending on the typeof panning needed in various circumstances. These take in consideration Camera-speed versus depth of field (F-Stop) which of course impacts on the Focal-range to your subject.Most of these are concerned with Film ~ But in general there are 2 types of Panning,viz:- 'Static-Panning'......For Land & Seascapes and static objects etc....Technique.1'Dynamic-Panning'..For moving objects,People,Vehicles and such....Technique.2This gets down to how much time is needed for the Camera to process its Movie-frames and more time to write data to its "SD(HC.HD)Memory Card ~ provided its the correct Card in the first place. There are a few simple Charts & Rules about this but I need a little time to dig them out.Will get back to you soon...Brian.P.S There a lots of articles about this on the WEB simply search for 'Camera-Panning' Quote Link to comment Share on other sites More sharing options...
