Brian: You can read with more detail the data transfers calculations in this Topic (seventh post from top to bottom). http://www.davidrubio3d.com/view_topic.php...amp;forum_id=44 But for a short answer, I would say that with currently Laptops HD's speeds is not possible. The fastest Laptop HD speed is 7200 rpm, but even with this speed the Minimum Transfer Rate is 26.2 MB/s. Please see this chart: http://www23.tomshardware.com/storage25.ht...4&chart=146 That speed works fine for 720p. This is the formula: 1280x720= 921,600 pxs. x 24 (fps)= 22,118,400 or 22.1 MB/s. But for that speed to be achievable and "clean" so to speak, the video stream recording has to be made in a separate Hard Drive from the OS (Operating System). A Firewire external HD might work, but I have not made tests to be 100% sure about this. This is a "chart" of HD space that you need to record 1 hour of Raw uncompressed video: The HD's capacity is calculated using the number 1,048,576 instead of just 1,000,000.* 720p 1280 x 720 x 24 fps x 1 byte (8 bit) = (2,2118,400 / 1,048,576 )=21.09 MB/s* x 60 sec x 60 mins. = 75,924 MB's or 75.9 GB's 1280 x 720 x 24 fps x 2 bytes (10-16bit) = 42.19 MB/s*x60x60= 151.8 GB's. 1080p 1920 x 1080 x 24 fps x 1 byte (8 bit) = 47.46 MB/s*x60x60= 170.8 GB's 1920 x 1080 x 24 fps x 2 bytes (10-16 bit) = 94.92 MB/s*x60x60 = 341,712 GB's Thanks, Cesar Rubio.

Troy: With the Pike F-145c you can achieve: At 1388x1038= 25 fps. And to calculate other resolutions this is the formula: 1388x1038= 1,440,744 pxs. 1280x720 (720p)= 921,600 pxs. Now divide 1,440,744/ 921,600= 1.56 Multiply 1.56 for the full frame resolution at 25 fps....1.56x25= 39 fps. For the Pike F-210c is this. 1928x1084= 2,089,952 pxs. at 30 fps. 1280x720= 921,600 2,089,952/ 921,600= 2.26x30=67.8 fps! That formula is the same for any MVC and any resolutions.

Robert, I live in Cambridge Wisconsin...But I don't think that I am a Cinematographer (yet). If I can be of any help, let me know please. Cesar Rubio. Cambridge Wisconsin, USA. http://www.davidrubio3d.com/

Troy: Before you buy anything, please wait for the images and videos of the Pike F145c. At $3490 and with those specs. (720p)...it might be worth buying! Thanks, Cesar Rubio. Cambridge Wisconsin, USA. http://www.davidrubio3d.com/

Troy: Well done with your work, I could not make it any better, congratulations! The Pike 421-c has a 1 1/2" Kodak CCD sensor, which measures 15.2 x15.2"mm. With an AOI (Area of Interest) at 16:9, is 15.2x8.5mm which is bigger than any 16mm format. Also the Pike F-210 having a native resolution of 1080x1920pxs. (HD 1080p) and a sensor of 14.3x 8mm, is bigger than the Ultra 16 format ( 1:1.89 aspect ratio and 11.66x7.49mm physical size). Charlie: The full frame of 35 mm film measures 36x24 mm, but it only applies for photography. For Motion pictures is 22x16mm (1:1.85 aspect ratio). Thanks, Cesar Rubio.

Troy: I cut my beard yesterday or I should say 2 days ago... :D ..Yeah I know, I looked like a cast away! Thanks for noticing the grids, I did too, but the final results are not like that. I have to look more into that situation. See this stereo videos (the last one). Please do not make a 400% magnification on them, they will look awful too! http://www.davidrubio3d.com/view_topic.php...amp;forum_id=44 HD 720 having 4 times the resolution of those shots, and the smaller pixels, will look better! Thanks, Cesar Rubio.

Phil: Right now I am working with my Computer set-up and the triggering system for perfect synch with two cameras. When it’s ready I will post some 3-D videos. I only have a SD set-up at home with two Marlin's F-033c and the quality looks good for me! (Personal use) Probably by the end of next week or beginning of the following one, I will post some footage of a Pike F-145c that I am waiting for. That camera shoots 720p which is 4 times the size of 360p (360x640 pxs. 16:9 of 480p). Most TV stations work with either 720p or 1080i....1080p requires too much bandwidth for transmition! Here is a still image of the Marlin F-033c: http://www.davidrubio3d.com/view_topic.php...amp;forum_id=60 A 1 1/2" sensor might be comparative to a 16mm film format. See the attachment for the real size in mm of sensors. Troy: There are some 35mm lenses adapters to fit c-mount cameras, but I have not tested one yet. I am planning to buy one for my Nikon lenses. They cost around $75 US dlls. Thanks, Cesar Rubio. Sensor_Size.bmp

Phil: The AVT Pike F-210c has a 1' Kodak CCD with global shutter (full frame read outs). It can record 1080p at 30 fps. Also the pixels size are 7.4 x7.4 microns. The price is $5650 but it's worth every single dollar! You can also get the AVT Pike F-145c (720p, 30fps) that has a 2/3 CCD Sony sensor, with global shutter and pixels size of 6.45x6.45 microns. The price is $3490 I don't really see the need over 720p, if you ain't going to show your work on the BIG screen. Actually I have knowledge of some movies shot with SD cameras, and transferred to film for BIG screen projection. I haven't see the quality thought. Thanks, Cesar Rubio.

Troy: Nice name...I like the movie very much! I don't want to steer away anybody from this excellent forum, but all the questions & concerns that you have, it would be better to post them on the images topic , so Scott Smith could answer them for you (and everybody interested) He has limited time and he does not usually participate on forums. For the price list, I will soon post it on my forum to everybody to see. One thing that I can tell you is that the Pike F-145 c list price is $3490 and I honestly prefer 720p over 1080p if you are not going to show your work on a big screen Digital Cinema. For the sendor size comparison see this please: http://www.dalsa.com/dc/origin/dc_sensor.asp The small HD (in red) sensor is a 2/3" the same as the F-145c and the 1" on the Pike F-210 is a little bit bigger than that. the 16mm film size is precisely that 16mm in width. A 1 inch CCD is only 12.8mm. So you get a better DOF for 3-D work with Digital Cameras. Thanks. Cesar Rubio.

Hi all: I would like to know what professional cinematographers think about the future of 3-D Digital Cinema and of my Forum of course. http://www.davidrubio3d.com/ Any honest "critique" would be appreciated. Thanks. Cesar Rubio

NOTE: This is a edited post. In the previous one I had problems editing it. Phil: You are not the one from the Sopranos right?...I am just kidding (lol):D The charts images were taken in the AVT installations on Massachusetts USA. Tomorrow I will have Scott Smith's answers for some of your questions. The ugly Images of me, were taken with a Markin F-033c which has a IR (Infrared) cut filter by default (you can remove it, and put it back if you want) The non "c" (color) version, does not have this filter and it gives better resolution for monochrome (black & white) images. I used the AVT SmartView 1.5.1 to grab single images.That software comes free (among other software applications) with every AVT Camera. For recording to disk (continuos video) I use the Stream Pix 4.3 software. Thanks for your interest, we'll have more info later so stay "tunned". Cesar Rubio.

Hi everybody: First day and post. I hope I won't offend anybody or break a forum rule with this. I have some Images to show on my forum that were taken with AVT Cameras, just in case somebody wants to see them at: http://www.davidrubio3d.com/view_forum.php?id=3 Thanks and nice forum. Cesar Rubio
