coopernatural Posted February 16, 2009 Report Posted February 16, 2009 Hi All,Have put up a slideshow on http://beechbrook.com/pte/ (thanks Bill) It's called Kirkistown Track Day.It is nearly all pans and zooms,as I wanted to get across movement. Following the recent posts on the trouble some were having with the jerky playbackon their equipment,this might be a candidate as a hardware test.I had problems with it playing on low specced machines though it plays fine on my home PC.Davy Quote

coopernatural Posted February 16, 2009 Author Report Posted February 16, 2009 Hi Ken,OK you passed the Hardware Test and spotted the 'forgot to enable manual control.'To pass with full marks though,you just have to be able to point out to me howsomebody would enable manual control .Once is too once too often for a burn on hot pipes.Davy Quote
jfa Posted February 16, 2009 Report Posted February 16, 2009 About 1sec after the image is at full brilliance I get a slight jump in the pan. Happens on all the images after the Honda vti, (3rd image on).Apart from that all OK.

coopernatural Posted February 16, 2009 Author Report Posted February 16, 2009 Hi John,This could turn out to be interesting.I suppose I should put the spec of my PC here.Win xp Pro 64bit SP2CPU Intel 2.4 gig Core 2 Quad66004 gig of ramNvidia 8800 GTX 768 meg VramI just downloaded latest drivers for the Nvidia card.Might be worth checking their site.Also see if there is a 'Sync lock' box you can tick.Not sure if you need to download the Nvidia panel to your PC if it's not already on your machine.Might be worth a tinker and a tweak Thanks,Davy Quote
Guest Yachtsman1 Posted February 17, 2009 Report Posted February 17, 2009 Just checked the show on my Samsung G15 laptopIntel dual core processorATI Radion 1250 Express graphics card4gb ramXP Pro SP3.80% of the pans blipped at midpoint almost un-noticeable but I could see them, saying that if you did this for real I think your audience would soon be sea-sick.Nice pictures, needs more sound effects.Yachtsman1 Quote

cjdnzl Posted February 17, 2009 Report Posted February 17, 2009 Curiosity got the better of me, and I downloaded and ran your show.The pans were absolutely smooth all the way through two runs of the show, with no sign whatsoever of skip or jerkiness - but I concur with Yachtsman that you could make your audience motion-sick! Twice through and I was feeling a touch queasy!My computer is a Dell 1520 laptop, Intel Centrino duo-core 1.8 GHz CPU, nVidia 8600M-GT GPU with 256MB vram, a 1680 x 1050 display, and 3 GB of memory. I am of the mind that one needs something like the 8-series nVidia GPUs for good results with this amount of panning.Photography is excellent also, I would think a dslr was used for the shots.Colin Quote
Guest Yachtsman1 Posted February 17, 2009 Report Posted February 17, 2009 If anyone is considering building a test slide show as the original idea, can they keep within the constraints as per the PTE manual regarding picture size & resolution, keep it to say 10 slides, and advise the file size in their post . Downloading this one kept me out of bed, 10 MB max should be easily acheivable. Yachtsman1 Quote

Ken Cox Posted February 17, 2009 Report Posted February 17, 2009 Eric et althe file size is always indicated at Beechbrook and generally Bill's server will give a max d/l speedmy max is 300kb/sec -- that max speed is what the isp tech's say is all i pay for -- i sat here and watched him set it up - he tried to give me more but the guy that was monitoring my speeds said no -- people that are on cable generally get twice as muchi thought Davy's show was great but i guess one has to be a race buff to appreciate it!ken Quote
coopernatural Posted February 17, 2009 Author Report Posted February 17, 2009 It's interesting to see what actually runs OK with the different PCs here. I was thinking it may have been down to Video Card settings,or the ammount of Video ram on the card,but I think you may well be right and it's more down to the processingcapability of the Card.I used 2 cameras. 1 was a Pentax Clone (Samsung) dslr and the other was a Nikon D300.Davy Quote
davegee Posted February 17, 2009 Report Posted February 17, 2009 I'd be interested to know the Pixel sizes of the images and their file size in Mb?DaveG Quote
coopernatural Posted February 17, 2009 Author Report Posted February 17, 2009 I'd be interested to know the Pixel sizes of the images and their file size in Mb?DaveGDave,Pixel sizes are 2048 x 1360 and file size around .4 Mb .I didn't deliberatly set out to make some definative test show,(I wouldn't know how)as I had just about gave on it, as it wouldn't play well on other friends PCs.There might be some merit in gauging what will and won't work. For some,it may be of some use in allowing them to adjust PC/Graphics card settings to make it play better.So many variables even for 2 similarly specced machines, a test like this dosen't prove anything except to a degree, how each individual machine (including software and configuration) will perform in playing this file.With enough feedback from users though, it might give an indication of what might work and what might not.What helps and what dosen't.The slideshow has not been made to give a predetermined pass/fail test for PCs.Just more of a workout challenge.If anybody wants to design a more useful set of performance tools (PTE Olympics),I'd be interested.Davy.

Ken Cox Posted February 17, 2009 Report Posted February 17, 2009 Davyhave asked before but no takers ken Quote
Almark Posted February 28, 2009 Report Posted February 28, 2009 Davy,no need for "Pixel sizes are 2048 x 1360 and file size around .4 Mb ." Talk to me at the Cc and I will show you how to get these down to either 1024x768 or 1400x1050.Tut FYIhttp://www.bangor-camera-club.co.uk/bangor...ets/pdf/PDI.pdf Quote
davegee Posted February 28, 2009 Report Posted February 28, 2009 Davy / Mark,The show plays OK on my desktop machine but consider this:The show is "Fullscreen" and I'm viewing on a 1920x1200 monitor so the images, for the most part, are zoomed and panned beyond the limits of their 2048x1360 resolution (on my monitor).Getting the resolution of each image down to 1400x1050, as Mark suggests would make the situation even worse in terms of image quality unless the "window" of the show is limited to 1400x1050 and no pans or zooms were applied, which was not the object of Davy's excercise.I'm beginning to think that the image resolution means very little unless the resolution of the monitor on which the show was created is given?Any thoughts, anyone?DaveG Quote
JEB Posted February 28, 2009 Report Posted February 28, 2009 Hi,PICK THE BONES OUT OF THIS!Played on two laptops.HP Pavilion1440x900 nativeGO7600 256 MB2046 MB RAMIntel T2500 @ 2.00 GHzXP Home SP3Played very smoothly.HP Compaq1024x768 set to.ATI Radion 128 MB1536 MB RAMAMD Turion 64 1.58 GhzXP Pro SP3Very jumpy on every slide.Hope this adds something that can help us come to some sort of conclusion.John Quote
coopernatural Posted February 28, 2009 Author Report Posted February 28, 2009 Mark,Had made a 1024 x 768 version with static images. To give some headroom for some fairly long pans in this version,I purposley used a higher resolution to maintain the image quality.Davy Quote
Almark Posted March 1, 2009 Report Posted March 1, 2009 Davy, you are quite right. I forgot about the pan and zooms. You did tell me this - another senior moment! I have found images of 500k to work fine in fades, but as I never use anything else, I do not know how they work with pans and zooms - that clearly must use much more system resources.Viewed on 1920x1200 on my main Pc and on 1920x1080 on my laptop the show was image and transition perfect.
