In-Camera Recording in the EOS C500 and C300
Both camera employ identical in-camera recording capabilities. They both deploy an MPEG-2 codec to
do this recording.

More specific details of the in-camera recording are summarized in table 2. It will be noted that both
are “worldcams” in that they originate and record all of the internationally standardized digital HD
formats. In the case of the C300 this recording can constitute the primary program capture. In the case
of C500 it is used as an HD proxy of the separately and externally recorded uncompressed 4K/2K/HD
material – for use in the offline editing process.

EOS C500 as High performance 2K or HD Acquisition System
Where the C300 is intended as a compact camcorder with on board MPEG-2 recording, the C500 is
intended to originate considerably higher performance 2K or HD digital component video which is then
captured on a broad choice of world renowned external digital recorders.
Comparing Figure 4 with the
previous Figure 3 will reveal the significant elevation in the 2K/HD performance of the C500.

distinguish it from the C300
What is Unique about the 2K or HD Video Components in EOS C500
There is a distinct benefit to structuring the RGB video components in the manner described – in terms
of delivering unprecedented overall image quality in the 2K / HD RAW output:
1. Full and equal bandwidth RGB 4:4:4 video components
2. Selectable as 12-bit or 10-bit RGB components
3. Because no debayering process is required – any form of reconstruction errors and associated
aliasing artifacts are totally avoided
4. No compression is applied to these RAW signals
5. The direct readout of the four separate video components: R Gr Gb B as a 4 : 4 : 4 : 4 set
of 1920 x 1080 (or 2048 x 1080) is followed by the digital summation of the two green
components Gr and Gb – to produce the “Super Green” that has been one of the striking
differentiators of the C300, C100, and C500 cameras. That special Green video has (a)
enhanced dynamic range, (b) higher resolution, and (c) virtually zero aliasing – see Ref [2].
