A SDHC card with the capacity of 16 GB can hold up to 2 hours of video recorded at highest quality setting. When recording to a memory card, the recording time depends only on capacity of the card. The HF100 uses full-size SDHC memory cards. One 4 GB card can fit roughly 30 minutes of video at highest quality setting (FXP).
Canon G12 records videos up to 720p HD quality, G15 1080p HD and G1 X 1080p. G15 and G1 X do allow to use zoom and autofocus during video recording. Many of the changes made allowed the G7 to be significantly slimmer than previous G series cameras (e.g., the thickness of the G7 is 4.25 cm while the G6 is 7.3 cm), making it more portable.
The following cameras allow audio and video to be shot in at least one raw (in the sense of a series of raw image format frames, such as in CineDNG) format. Lossy compression may be present. However, "raw" means the image data should not have gone through demosaicing and further processing, or at least the process should be reversible.
PowerShot is a line of consumer and prosumer grade digital cameras, launched by Canon in 1996. [2] In 1996 the first model was introduced to the market, the PowerShot 600, which came shortly after Canon released and subsequently discounted its SV series in 1992 and switched to digital cameras.
This mode is found on some Pentax cameras; on many cameras (such as Canon and Nikon) this is not a separate mode, but instead is accomplished by using Program mode and manually selecting an ISO. TAv: Some Pentax cameras such as Pentax K-50 has this mode for rapidly changing lights by using the widest aperture and the lowest ISO of continuously ...
The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.
Video quality is a characteristic of a video passed through a video transmission or processing system that describes perceived video degradation (typically compared to the original video). Video processing systems may introduce some amount of distortion or artifacts in the video signal that negatively impact the user's perception of the system.
Broadcast quality is a term stemming from quad videotape to denote the quality achieved by professional video cameras and time base correctors (TBC) used for broadcast television, usually in standard definition.
