A sound blimp is a housing attached to a camera which reduces sounds, such as shutter click on SLR cameras, and motors on motion picture cameras. It is primarily used in film still photography, so as not to interfere with the shooting of principal photography [dubious – discuss], and also in other situations where sound is distracting: theatrical photography, surveillance, and wildlife ...
Noise, static or snow screen captured from a blank VHS tape. Noise, commonly known as static, white noise, static noise, or snow, in analog video, CRTs and television, is a random dot pixel pattern of static displayed when no transmission signal is obtained by the antenna receiver of television sets and other display devices.
Alternatively, a tally light can be a separate device mounted on the camera body, lens, or tripod, but not connected to the camera electronically. In some (mainly non-studio) cameras, the tally light is implemented as a special UI element displayed on the screen (e.g. red outline around the frame).
An effective noise reduction method for this type of noise is a median filter [2] or a morphological filter. [3] For reducing either salt noise or pepper noise, but not both, a contraharmonic mean filter can be effective. [4] Linear filters are generally ineffective for removing impulse noise. [1]

If this is a single pixel, it is likely (but not certain) to be spurious and noise; if it covers a few pixels in an absolutely regular shape, it may be a defect in a group of pixels in the image-taking sensor (spurious and unwanted, but not strictly noise); if it is irregular, it may be more likely to be a true feature of the image.

These cameras do not require a video capture card because they work using a digital signal which can be saved directly to a computer. The signal is compressed 5:1, but DVD quality can be achieved with more compression (MPEG-2 is standard for DVD-video, and has a higher compression ratio than 5:1, with a slightly lower video quality than 5:1 at best, and is adjustable for the amount of space to ...
