1. your camera (manufacturer & model)
answer:
- Nikon D3100
2. the sensor size (in mm: ? x ?), maximum megapixel rating, sensor type (eg “APS-H”)
answer:
- APS-C (23.1mm x 15.4mm)
3. lenses you own & can use on your video recording-capable camera
— in 35mm equivalent focal length range, associated widest apertures
answer:
- AD-S NIKKOR 18-55mm 1:3.5-5.6G
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
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:
- SD HC card: 32GB Class 10 300x (My memory card)
5. How many minutes of video capacity does your biggest memory card have shooting at both the
Class of card I need for video shooting: Try to find SD cards that are UHS speed class or SD card with a V shown. The
the ones with V are recommended for the most high quality and best performance for video recording.
Class 10 is the minimum quality for a good video shooting. It is fast enough for minimum requirements.
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: 16gb / 1920 x 1080; 24 fps 10 mins
- lowest resolution no. of minutes: 16gb / 640 x 424; 24fps 10 mins
6. maximum file size per clip
answer:
- 4GB
8. format 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 and MPEG4(From my camera Nikon D3100).
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:
- 1080p / 1980 x 1080 pixels / SD / 16:9 / 24 fps
- 720p / 1280 x 720 pixels / 16:9 / SD / 30 fps
- 720p / 1280 x 720 pixels /16:9 / SD / 25 fps
- 720p / 1280 x 720 pixels / 16:9 / SD / 24 fps
- 424p / 640 x 424 pixels / 4:3 / SD / 24 fps
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?
(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:
- 4:3 aspect ratio gives a more square wish screen while 16:9 aspect ratio gives a wider screen, the
standard of high definition picture. (It comes with black bars)
11. shutter 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:
- Depending the fps I have, with 30 fps, I'd use 1/60. With 24fps, I'd use 1/48 or around 1/50.
12. aperture: does your camera permit you to set the aperture when recording video?
answers:
- Yes, I have to do it manually.
13. shutter 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:
-
14. focus: 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:

answers:
- My camera permits me to manually focus and autofocus. I'd rather manually focus since it's easier
to manipulate while autofocusing keeps moving and tries to focus the spot.
15. your camera records video at what data rate (expressed in MB/sec. or mbps)
answer:
- Might be 24mbps.
- Might be 24mbps.
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
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:
- There is nothing specific or particular settings recommended for my camera.
