Canon EOS R5 Records 4 Hours 4KHQ At 30p Video Externally With Some Simple Tricks

The Canon EOS R5 can record up to 4 hours of 4KHQ video at 30p with an external recorder, if you know some simple tweaks.

The tweaks have been discovered by No Life, and are documented in the video below. Wayne of No Life says:

The Canon R5 does not seem to overheat, externally, if you don’t have any cards in the camera. In this video I show (with as much proof as I can), how I’m able to record up to 4 hours in 4KHQ 30fps, 10-bit CLOG, with IBIS and DPAF all on, with no issues like the blackout or screen off issue myself and Gerald were having.

The setup here is as follows – HDMI out of Canon R5, into Atomos, out of Atomos, into ATEM, out of ATEM, into OBS on the PC. This is no different that Geralds livestreaming setup, and showcasing the times you can expect as if you were recording on the Atomos. This was to record for this long period of time, without the MASSIVE Atomos file, and still show the camera was in fact running for the entire time.

The EOS R5 seems to be highly regarded as a stills camera. In particular, the autofocus system seems to be huge leap forwards. More Canon EOS R5 review stuff is listed here, for the EOS R6 see here. User manual are available for download for the EOS R5 and the EOS R6.

Canon EOS R5 product description :

For the professional image-maker who needs resolution, speed, and video capabilities, there is the Canon EOS R5. Setting a new standard for versatility, this full-frame mirrorless camera features a newly developed 45MP CMOS sensor, which offers 8K raw video recording, 12 fps continuous shooting with a mechanical shutter, and is the first EOS camera to feature 5-axis sensor-shift image stabilization.

Beyond just resolution, the sensor also pairs with the refined DIGIC X image processor to usher in a new generation of Dual Pixel CMOS AF for quick, smooth, and intelligent focusing performance using 1053 selectable points that cover the entire field of view. This focusing system has also been updated to make use of Deep Learning technology for improved subject tracking as well as precise eye, face, and head-detection for both people and animals.

Complementing the imaging assets, the R5, while sporting a new design, also feels familiar to EOS 5-series users. An especially high-resolution 0.5″ 5.76m-dot electronic viewfinder provides a realistic 120 fps refresh rate while the 3.2″ rear touchscreen LCD monitor sports a vari-angle design to accommodate vlogging needs as well as benefit working from high and low angles. A top status LCD makes for an intuitive workflow and the camera also incorporates dual memory card slots—one CFexpress Type B, one SD UHS-II—along with Bluetooth and Wi-Fi wireless connectivity.

45MP Full-Frame Sensor and DIGIC X Processor

Built around a newly developed 45MP full-frame CMOS sensor, the EOS R5 review offers both high-resolution stills and video output and the fine-tuned DIGIC X image processor complements this with a wealth of speed. Sensitivity from ISO 100-51200, which can be expanded to ISO 102400, suits working in a variety of lighting conditions while quick continuous shooting up to 12 fps with a mechanical shutter, or silent 20 fps with an electronic shutter, is ideal for working with moving subjects.

8K30 Raw and 4K120 Video Recording

Benefitting more than just stills, the 45MP full-frame sensor also enables impressively high-resolution DCI 8K 30 fps raw video recording internally along with 4K recording up to 120 fps in 4:2:2 10-bit with Canon Log. HDR-PQ recording is possible, too, in-camera HDR production and external recording, via the HDMI port supports a clean 4K output at up to 60 fps. Both All-I and IPB compression options are available, along with the ability to use Dual Pixel CMOS AF when shooting at up to 8K raw.

Dual Pixel CMOS AF II

An updated Dual Pixel CMOS AF II features 1053 selectable focusing points, which cover approximately 100% of the image frame for wide and even coverage. This focusing system offers smooth and fast focusing performance in a similar manner to how a camcorder acquires focus. This system integrates two separate photodiodes within each pixel to provide a broad and dense network of phase-detection gathering elements across a majority of the image sensor to reduce focus hunting for faster, more direct control of focus placement. When working with still imagery, this focusing system works to acquire focus quickly and accurately, making it ideally suited to shooting and tracking moving subjects so that critical focus is attained with each shot. When shooting video, a Movie Servo AF mode offers smooth and natural focusing when changing from different subjects or different distances within the scene, as well as the ability to specify tracking sensitivity, AF speed, and Face Tracking priority. Benefited by the Touch AF system, rack focus is possible simply by touching elements within the scene on the touchscreen in order to change focus in an intuitive manner. Subject tracking in movies is also heightened due to the Dual Pixel CMOS AF system’s ability to recognize subjects and maintain focus when working within changing or cluttered scenery.
