EOS-1D X: Video Shooting Workflow
   
Improved Image Quality
The many improvements of the sensor and processing technology of the EOS-1D X benefit the video side of the camera as well. The Full Frame sensor with dual DIGIC 5+ processors offers a large step up in core sensing ability.
Low Light Sensitivity
  • Larger, full-frame sensor enables camera to gather many more photons and be more sensitive in low light environments
    • Sensor is designed for outstanding HD video quality, as well as 18 million pixels for great still images
    • Can shoot HD video up to 51,200 ISO
  • High-ISO noise on the EOS-1D X has a 2-stop improvement over the
    EOS-1D Mark IV
    • ISO 6400 looks like ISO 1600 on the EOS-1D Mark IV
  • Can use large aperture lenses like the 85mm f/1.2
Less Moir� and Artifacts
One technical challenge of capturing video data is the change in resolution from the native sensor size to the video frame size in real time at up to 60 frames per second. The dual DIGIC 5+ processors offer increased performance, which allow more intelligent processing to be done to go from 18 megapixels to 1920x1080 Full HD.
And the CMOS imaging sensor is designed to reduce moire effects and visible artifacts during video recording.
New �ALL-I� video compression
The EOS-1D X adds an "ALL-I" video compression method to complement its other "IPB" option. These names refer to different types of frames in video compression.
An I-frame is like a key frame and is only compressed using intra-frame compression which only uses the data in that specific frame. P and B frames refer to frames that only record changes from the previous I-frame, known as inter-frame compression.
  • ALL-I compression method
    • Each frame is treated as a separate image, and compressed individually
      • Only compresses using the data within the frame
      • Potentially fewer motion artifacts
      • Larger file sizes, vs. IPB method
      • Best video image quality option for EOS-1D X
      • Biggest benefit is that it’s easier to edit
  • IPB compression method
    • Frames between “key frame” are compressed, referencing previous and subsequent frames in compression process
      • Smaller files; more effective compression
      • Roughly equivalent file sizes to previous EOS HD video,
        but improved video image quality
      • High compression requires extensive computer power for effective viewing and editing
  • Users have requested these features:
    • Editors using Apple software
      • Can now edit footage natively with ALL-I compression, as opposed to transcoding IPB
    • Videographers filming high speed motion
      • Sports, Combat, etc.
      • If an artifact occurs, it’s usually caused by motion not handled well
        by compression

The EOS platform already uses an extremely high quality compression “codec”.
But the EOS-1D X takes it a step further. The dual DIGIC 5+ sensors improve the compression by adding more processing speed for a bigger search area, and more CPU power to apply better algorithms. This combined with better starting
quality video, results in extremely high quality video now with two different options
for compression.
