1. your camera (manufacturer & model)
answer:
Canon 1200D EOS Rebel T5
2. the sensor size (in mm: ? x ?), maximum megapixel rating, sensor type (eg “APS-H”)
answer:
             -Senor SizeAPS-C (22.3 x 14.9 mm) 
-Maximum Megapixel : 18 Megapixels
-Sensor Type: CMOS

3lenses you own & can use on your video recording-capable camera 
    — in 35mm equivalent focal length range, associated widest apertures
answer:
-  18mm lense
    Equivalent is 28.8mm at 4.5
-   55mm lense
    Equivalent is 88mm at f 4.5

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:

-  Class 10
no other information my card

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 / 1920 x 1080p 30 minutes
- lowest resolution no. of minutes: 32GB memory Card / 640 x 480 25fps 30 minutes


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:
             
-H.264
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:
 30fps(options) 1920 x 1080 16:9

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:

-1920 X 1080 is a 16:9 aspect ratio
-1280 x 720 is a 16:9 aspect ratio
-640 x 480 is a 4:3 aspect ratio


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:
-I have manual exposure controls in video. I can shoot from 1/30 to 1/4000

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

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:

-I can focus manually
15. your camera records video at what data rate (expressed in MB/sec. or mbps)
answer:

-216 MB/min


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.
