Full HD Recording and Super 35mm Crop Mode In addition to standard frame rates of 30fps, 25fps and 24fps, the EOS-1D C also enables Full HD recording at 60fps and 50fps and supports high-speed shooting for spectacular slow-motion footage. The camera's built-in LCD monitor can both preview and play back footage at its native frame rate. The EOS-1D C also supports Super 35mm Crop in Full HD at 30fps, 25fps, and 24fps. Image compression is H.264 and HDMI support permits external monitoring and playback of footage independent of shooting mode. When monitoring Super 35mm Crop images, the monitor automatically masks the image to aid composition.
