-
IMPORTANT ELEMENT ON DIGITAL CAMERA
DATA COMPRESSION (CODECS)
PROCESSOR (BIT RATE)
PIXELS SIZE - SENSOR
ADDITIONAL FEATURE (firmware,LUTs)
INTEGRATED WORKFLOWS WITH OTHER PLATFORM
-
DATA COMPRESSION (CODECS)
Special compression made by the factory (commercial value) Designed to be integrated with other platforms. (post production) Optimized Data/information recorded. (Color,Textures) Samples: ARRI ALEXA - ARRIRAW REDCAM - REDRAW GOPRO HERO3 BLACK EDITION - GOPRO CINEFORM BLACKMAGIC CAMERAS - RAW DNG CANON C500 - CANONRAW All codecs can be converted to the other codec, downgrade-able (transcoding).
RAW - ProRes 2K, ProRes HQ, Prores LT, ProRes proxy, DPX 10 bit.
-
PROCESSOR (BIT RATE)Optimized processor designed for market needs (commercial value)
Faster/bigger bitrate = bigger file = more information recorded.
Samples:
REDCAM capable of recording at a data rate of up to 450MB/s
ARRI ALEXA has a bit rate of 1.34 Gigabit per second at 24 fps CANON 5D MARK III HD bitrate 38 megabits per second (4.8 Mbyte/s) PANASONIC GH4 bitrate video recording at 200 Mbps
-
PIXEL SIZE (SENSOR)
-
PIXEL SIZE (SENSOR) Acomodate the market demand for viewing
experience. More space area for post production process
(SFX) Fast trend : 2K projection, 4K projection and 8K
projection. (hyper reality)
-
ADDITIONAL FEATURES
upgradeable firmware,LUT,etc. RedCam system: timelapse,speed ramp,motion sensor.
BlackMagic design: multi codecs, upscale size (application base) Panasonic GH: Picture profiles, firmware hack.
