Canon C100 – Troubleshooting – Video is interlaced when recording progressive

PROBLEM

My Canon C100 is set to record at a progressive frame rate but the monitor is showing it as interlaced video.

My Canon C100 is set to record at 24 frames per second but the monitor is showing 29.97 or 59.94.

SOLUTION

This is a known issue with the C100’s HDMI output settings. The HDMI output settings are independent of the camera’s recording mode. On the camera’s menu, under Video Setup > HDMI > Output, there are only two choices: Normal, and 1920x1080 59.94P. However, the 59.94P setting still does not actually output a progressive image. This is a Canon bug. All of the video output is actually 1080i29.97 frames (59.94 fields). This only impacts the HDMI output; video recorded in the camera will be in the chosen frame rate and progressively recorded. The monitor will still be useful for framing, exposure, focus, etc. It simply won’t be showing exactly the frame rate that is being recorded internally.

If you are having combing artifacts from the interlaced video, change the deinterlacing mode from “Weave” to “Bob”. This mode can make thin horizontal lines appear to jump up and down but is generally less distracting than the combing artifacts. In the Settings menu, under Controls > Interlace select Bob instead of Weave.
