DSLRs Camera and Video Format

103 23
Most newer DSLRs (Digital single-lens reflex camera) and all mirror-less interchangeable-lens models offer HD video capability.
Some offer 1080 Rill HD and others offer 720 HD.
The 1080 format provides videos 1920 pixels wide and 1020 lines deep.
The 720 format provides videos 1280 pixels wide and 720 lines deep.
Most cameras also offer SD video, which measures 640 pixels wide and 480 lines deep (fewer lines deep with some cameras).
When viewing videos on an HD television or full screen on a computer, higher-resolution video generally looks sharper and clearer with less artifacts.
Some video-capable DSLRs (Digital single-lens reflex camera) and mirror less cameras provide a choice of frame rates.
Common ones include 30 fps, 24 fps and 60 fps.
The faster the frame rate, the smoother action sequences appear.
The 24 fps real matches the frame rate of professional motion pictures, and some feel this provides a more "cinematic" look.
For pro video work, you'll want the variable frame rate capability.
Note that the NTSC video standard for 24 fps is actually 23.
976 fps, 30 fps is actually 29.
97 fps, and 60 fps is actually 59.
94 fps.
Some cameras really shoot 30 fps and 60 fps; for pro work, this is less desirable than cameras that shoot 24, 30 and 60 fps at the NTSC 23.
976, 29.
97 and 59.
94 fps rates, respectively.
You'll also notice a word press " or "i" following the frame rate, 1080/30p, for example.
The "p" means "progressive" video, which displays one full image at a time at the specified rate.
The "i" means interlaced video, which displays the odd-numbered lines, then the even-numbered lines of the image.
Progressive video handles motion better than interlaced, provides entire frames for freeze-frame or still-image grabs, and has fewer artifacts.
Video-capable DSLRs (Digital single-lens reflex camera) and mirror less interchangeable-lens cameras output progressive video.
Some information about DSLR cameras and how to work: The simple operation of a DSLR (Digital single-lens reflex camera) is as practices: for viewing purposes, the mirror reflects the light approaching through the attached lens up wards at a 90 level angle.
It is then reflected 3 times by the roof pentameter, correcting it for the photographer's eyesight.
(Note that the diagram down below incorrectly exhibits a non-roof pentagram.
) Through exposure, the mirror putting together swings upward, the aperture narrows (if ended down, or placed smaller compared to wide open), shutter starts up, allowing that lens to project light on to that image sensor.
