Abstract
The original EOS C300 camera was introduced in November 2011. It uses a 4K single image
sensor to exclusively originate the 1920 x 1080 HD production format [1]. It records this on-
board using an MPEG-2 codec operating 8-bit YCrCb 4:2:2 @ 50 Mbps. The EOS C500
Camera followed in 2012 and supported external 4K RAW recording. The EOS C100 Mark II
was introduced in the latter half of 2014 and the EOS C300 Mark II was unveiled at NAB 2015.
The successor C300 Mark II camera [2] [3] offers significantly elevated video performance and
expanded operational capabilities. Unlike its predecessor, the EOS C300 Mark II Camera offers
a choice of 4K / UHD / 2K / HD origination and greatly extended on-board recording capabilities
by deploying a new codec based upon the more advanced MPEG-4 H.264 Advanced Video
Coding (AVC) compression algorithm. In addition, the C300 Mark II offers a choice of 4K or
UHD origination and recording using the XF-AVC codec [4] at a very high bit rate at frame rates
up to 29.97 fps progressive. Finally, the camcorder offers alternative uncompressed 10-bit 4K
RAW or 2K / HD component video outputs via a 3G-SDI terminal for external recording.
November 2016 – the fifth anniversary of the debut of the Cinema EOS system is witness to the
debut of the first A-Camera from Canon – the EOS C700. The accumulated worldwide
experiences with the C300 / C500 / C300 Mark II cameras and the ongoing dialog with the
production communities of both television episodics and theatrical motion pictures contributed to
the development of this fully fledged camera. The EOS C700 broadens the on-board recording
options for all of the production formats. It also has a dockable recorder that can record 4K
RAW at 12-bit at frame rates up to 60 fps and at 10-bit up to 120 fps. Unlike the other Cinema
EOS cameras that RAW signal has no baked-in video processing other than a unique new
OETF that enhances the capture of all of the impressive HDR details originated by the camera.
1.0 INTRODUCTION TO EOS C700 CAMERA
The central goal of the EOS C700 is to harness developments in the Super 35mm image sensor
and associated video processing to further refine HDR and WCG digital motion imaging
capabilities. At the same time, the increasing adoption of 4K / UHD for high-end program
origination spurred a significant expansion to their associated recording options in this camera.
Accordingly, the EOS C700 design placed a priority on five key advances beyond the EOS
C300 Mark II:
1. RAW Recording -- uncompressed 4K / UHD @ 12-bit up to 60fps and at 10-bit up to
120 fps – in a dockable recorder
2. On-board Recording – choice of either an XF-AVC codec or ProRes codec
3. On board Recording – of 4K and UHD – now extended up to 60 fps
4. On-board Recording – of 1080-line HD and the 2K digital cine format – up to 120 fps
5. On-board Recording – of a cropped 2K / HD – up to 240 fps
