What is the 4 culvert readout versus the 8 gully readout on a Canon DSLR camera?
The new T2i says it have a 4 channel readout compared to the 7D's 8 channel readout. What does this scrounging for video quality?
Answers: It means zilch for video quality because only a fraction of the sensor's resolution is used for that purpose and 4 channel works just fine as data streams stale the sensor. The difference is more apparent in shooting full resolution still descriptions where the extra channels sort a huge difference in how fast background can move from the sensor to the image processors. The 7D takes dominance of this by using dual image processors that allow it to shoot 8 frames per second. By comparison, the T2i only have one image processor and tops out at 3.7 frames per second which is less demanding of information throughput.
That said, neither camera by itself makes a good video camera. They don' "handle" similar to video cameras or shoot like video cameras and this becomes hugely clear when you start shooting with them. If you are serious about using them as video cameras, you will entail to purchase DSLR video support rig, including a follow-focus from vendors like Red Rock Micro and an external microphone to label these cameras useful for cinematography. Be warned that a solid baseline rig will glibly cost more than the camera and may exceed the cost of the camera and a good lens. Source(s): 7D owner
Can you give us a connection that talks about this 4 warren and 8 channel readout?
In most cameras there is a choice of bit depth (per pixel) when shooting RAW files where on earth 12 and 14 bit is typical.
When processing images, programs like Photoshop can set free processed RAW files in 8 bits/channel or 16 bits/channel, the channels man RGB, Red, Green and Blue (four possible channels.
As you may have guessed, shooting video at its topmost resolution, 1920 x 1080 (called HD) only uses 2 mp of the available 18 mp on the cameras sensor.
EDIT:
Thank you Eclipse for the explanation of the single and dual processing within those two cameras Source(s): digiPro
