1. your camera (manufacturer & model)
answer:

- Nikon D800

2. the sensor size (in mm: ? x ?), maximum megapixel rating, sensor type (eg “APS-H”)
answer35.9 × 24 mm Full Frame, 36 megapixels
-

3lenses you own & can use on your video recording-capable camera 
    — in 35mm equivalent focal length range, associated widest apertures
answer: 28-70mm f2.8, 80-200mm f2.8, 60mm f2.8
-  

4. biggest memory card you own in terms of capacity (in GB), class (eg “class 10”), 
   and card speed (eg. x 133)
   If it’s an SD type card, which class is it?  (e.g.. class 10)
   Read the following article from B&H PhotoVideo which indicates all relevant aspects of cards:
   Memory Cards Explained
   Which class of card do you need for shooting video? What does your SD card classification 
   mean in terms of writing speed: is it fast enough to be shooting video?
answers: I have a 32gb compact flash card, udma 7, 160mb/s

-  

5. How many minutes of video capacity does your biggest memory card have shooting at both the
     highest & lowest resolution capture settings?
     Also, does your camera have a limit on the amount of video shooting time?
     What is the technical reason for limiting single shot video shooting time?
     State your answers as memory card size / recording quality (resolution & mode) & maximum minutes
     ( eg. 8GB memory card / 1280 x 720p [SD mode] yields 20 min. of video)
     (NB. you will probably have to test this out by turning on your camera with your empty reformatted
     memory card installed, the display set to indicate total frames remaining/total video time available,
     video quality set to highest and then lowest resolutions)
answers:
- highest resolution no. of minutes: 32GB memory card / 1,920 x 1,080p [compact flash mode] yields 22 min. of video
- lowest resolution no. of minutes: 32GB memory card / 1,280 x 720p [compact flash mode] yields 44min


6. maximum file size per clip        
answer:
- 4gb


8format of movie files created (eg. QuickTime Motion JPEG, AVCHD, MPEG4, etc.)
    (... there’ll probably be more than one, depending on camera and resolution sizes & modes
answers:
-.mov
-
9. which video output resolutions does your camera produce? 
     try to include all of the following info for each level of video resolution your camera produces:
- (sample answer might be:     720p / 1280 x 720 pixels/ SD / 4:3 / 30fps)
               answers:
 720p / 1280 x 720 pixels/ compact flash / 16:9 / 60fps 50fps 30fps 25fps
-  1080p/ 1,920 x 1,080pixels/ compact flash / 16:9/ 30fps 25fps 24fps


10. looking at the above resolution dimensions available, are they using the same aspect ratio or not? 
      (eg. 800 x 600 is a 4:3 aspect ratio while 1920 x 1080 is a 16:9 aspect ratio). 
      What are the differing aspect ratios for each of your camera's video format resolutions?
answers:
- 16:9
-


11shutter speed range your camera can record video in: does your camera permit you to set shutter
      speed when recording video? (Can you in fact set manual setting for video shooting?) Whether it
      does or not, what shutter speeds can you set on your camera for shooting video?
answers:
- 25 to 8000

12aperture: does your camera permit you to set the aperture when recording video?
             answers:
-yes

    
13shutter speed & aperture restrictions — answer this only if your camera does not permit you to 
       choose manual video shooting settings.
       If your camera doesn’t have manual setting capabilities, what other camera setting can you use to
       control exposure then?
  answers:
-

14focus: how does your camera focus when shooting video? Does it permit you to manually focus
       or are you left with autofocus only?
eg. — The most important thing to know about the Nikon D5000’s video controls is the fact that the camera cannot 
autofocus while video is being recorded. You can autofocus the image before recording begins (by pressing the shutter 
button halfway down, just like you do with still images), but once you start recording you must manually focus 
everything..When you try to autofocus while recording, the camera lens moves and changes exposure just as if 
you’re autofocusing a still image.
answers
-  Yes the D800 permits me to manually focus before and while shooting the video.



15. your camera records video at what data rate (expressed in MB/sec. or mbps)
answer:
- 1920 -12mb/s ,24mb/s


16. specific and particular settings recommended for your camera model — the best way to 
      do this is to look at the camera reviews for your model on preview.com and/or imaging resource.com
      and read their review section on the video functioning (often listed as “video” or “movie” review section). 
      You can also research this in a Google search —eg. at least one very popular camera (hint: 5D) has
      suggested settings for ISO to obtain the least noise in video mode.
answers: The D800 is an overall good camera for video and pictures. With it's 36 megapixels the resolution is 
impecable.
