Canon EOS R5 II as a video device
 |
The Canon EOS R5 II is not only a new model of the corporate’s fashionable R5 mirrorless digicam; it is the non secular successor to the EOS 5D collection of ‘inexpensive’ full-frame digital cameras. That features the EOS 5D Mark II, the world’s first Full HD video-capable DSLR, a mannequin that reset the market’s expectations for video capabilities on ‘images’ cameras, and which, based on a number of Canon insiders we have talked to through the years, gave Canon the arrogance to develop extra aggressively into the digital cinema market.
Lots of the R5 II’s headline-grabbing specs have centered across the digicam’s picture capabilities, however it should not be a shock that the EOS R5 II is for filmmakers as a lot as it’s for stills shooters. Within the following slides, we’ll study what the digicam gives to film shooters.
Video specs
 |
The EOS R5 II consists of all kinds of resolutions and body charges to assist nearly any degree of video high quality. At its highest high quality, the digicam can seize DCI-style 8K Uncooked video internally at body charges as much as 60p. The R5 II additionally incorporates a new 4K ‘SRaw’ recording choice, with body charges as much as 60p. Canon hasn’t disclosed whether or not this 4K is downsampled from 8K or subsampled on the sensor, however it’s one thing we’ll check for our full evaluate.
When capturing compressed video, the digicam can seize 8K, 4K, and even Full HD resolutions in both DCI (1.89:1) or UHD (16:9) facet ratios, utilizing both the complete width of the sensor or a really slight crop (1.05x). This consists of 8K as much as 30p, subsampled 4K as much as 120p, and subsampled FHD as much as 240p. It is also attainable to seize 4K and FHD resolutions in each DCI and UHD ratios utilizing a cropped APS-C area of the sensor.
Lastly, when linked to an exterior recorder by way of HDMI, the digicam may also output 8K Uncooked at as much as 30p or 4K Uncooked at as much as 60p, each in a 1.89:1 facet ratio. We would be very shocked if this cannot be encoded as ProRes RAW as soon as Atomos has had a while with the digicam.
Codecs
 |
The R5 II consists of a number of codecs to assist its myriad video choices. When recording Uncooked video, the digicam gives the choice to document in both Canon’s Uncooked or Uncooked Gentle format. Video captured at body charges of 50p or increased makes use of the Uncooked Gentle format to maintain file sizes in test. After all, there’s additionally the aforementioned SRaw choice for 4K Uncooked video.
In an effort to higher align its latest mirrorless cameras with its Cinema EOS product line, the R5 II options Canon’s XF-HEVC S and XF-AVC S compressed video codecs, each of which may seize 4:2:2 10-bit shade. The XF-HEVC S format, based mostly on the H.265 codec, additionally lets you seize 4:2:0 8- or 10-bit video, whereas XF-AVC S, based mostly on the older H.264 codec, gives a 4:2:0 8-bit choice.
The R5 II additionally consists of the power to seize HDR video by concurrently capturing regular and underexposed frames, combining them to higher protect highlights in high-contrast scenes. This may be mixed with the digicam’s PQ image profile to be used on appropriate TVs or shows.
Rolling shutter
 |
Probably the most vital upgrades within the EOS R5 II is the addition of a Stacked CMOS sensor, which guarantees to enhance the digicam’s rolling shutter efficiency (although it is not practically as quick because the one in Canon’s new flagship mirrorless digicam, the R1).
We measured the R5 II’s rolling shutter fee when capturing DCI 8K video at ∼12.6ms. That is not going to set any information, however it’s sooner than the 15.4ms we measured for a similar decision on the unique R5, which ought to make rolling shutter artifacts much less noticeable on the newer mannequin.
Most Stacked sensor cameras do not seize video utilizing the super-fast multi-line readout modes they use for stills, so they are not as impressively quick. A sub-15ms rolling shutter fee is extraordinarily good, although, so that you’d have to actually provoke it to see any rolling shutter distortion.
C-Log2
 |
The EOS R5 II would be the first Canon mirrorless digicam to hit the market with Canon’s C-Log2 gamma profile. In accordance with Canon, that is a part of its effort to higher align video capabilities and workflows throughout its product line.
C-Log2 encodes a wider dynamic vary than the C-Log3 gamma profile included on some earlier Canon mirrorless our bodies and can higher replicate and match footage from Canon’s cinema cameras. Nevertheless, C-Log3 stays accessible to be used in much less difficult conditions the place the additional dynamic vary of the C-Log2 curve is not required, retaining extra knowledge per cease of sunshine.
Overheating
 |
The unique R5 acquired criticism for its propensity to overheat, notably when capturing 8K video. The R5 II may also expertise thermal points at its most demanding resolutions and body charges, however Canon has launched a brand new accent grip with a built-in cooling fan, the CF-R20EP, to assist mitigate this concern. It joins producers like Panasonic and Fujifilm which have supplied accent cooling followers for video-focused mirrorless cameras.
In accordance with Canon, when capturing 8K/30p video, the R5 II ought to run for as much as 26 minutes or as much as 37 minutes with the digicam’s auto power-off temperature set to excessive (based mostly on an unused digicam beginning in an setting of 23ºC/73ºF). With the accent fan hooked up, these occasions ought to improve to 106 minutes or 120 minutes (or extra). When capturing 4K/60p footage, Canon claims the accent fan will permit recording with out time restrictions.
The CF-R20EP has a advised retail value of $400. It additionally consists of an ethernet port for quick connectivity or distant operation.
Twin recording
 |
The R5 II features a new twin recording function that lets you seize high-resolution JPEG photographs whereas recording video. Utilizing this function, the digicam can seize Full HD video at as much as 30p on one card whereas capturing UHD 8K (7620 x 4230 decision) JPEG photographs at as much as 7.5fps on the opposite.
This function does have limitations. You may probably must optimize your shutter pace for both photographs or video, because the digicam makes use of the identical setting for each media. Additionally, some digicam features, equivalent to focus respiratory correction, chromatic aberration correction, diffraction correction, and in-camera picture upscaling, won’t work on this mode. Twin recording requires the brand new LP-E6P battery that may present extra sustained energy.
Video instruments
 |
Though the R5 II has some very spectacular video specs, we’re equally excited to see Canon embody useful instruments to higher assist the consumer expertise of capturing video. To begin, Canon has lastly added a waveform show to considered one of its mirrorless our bodies, permitting video shooters to guage publicity throughout the body when capturing video extra precisely. Equally, Canon has additionally added a false shade show, which makes it simpler to visualise publicity values in a picture or to rapidly dial within the right publicity for a specific a part of a picture, like pores and skin tones.
On the {hardware} aspect, the R5 II now features a full-sized HDMI port, an enchancment over the mini-HDMI port on its predecessor. It additionally has a entrance tally gentle to let topics know if you’re recording. It consists of 3.5mm headphone and microphone jacks.
Lastly, Canon has additionally added the power to pre-capture both three or 5 seconds of video, which ought to assist in conditions the place it is tough to anticipate when the motion will begin.
Multi-function sizzling shoe and digital/4-channel recording
|
The EOS R5 II additionally features Canon’s multi-function sizzling shoe, which incorporates communication pins for compatibility with equipment past speedlights. The unique R5 did not embody this function, although it appeared subsequently on the EOS R3.
The primary advantage of the multi-function shoe for video shooters is assist for digital audio enter, in addition to 4-channel audio assist.
Abstract
|
The unique EOS R5 got here to be referred to as a succesful video digicam, in a position to ship gorgeous video high quality, as soon as the preliminary concern about overheating had cooled. The R5 II goes the following step to handle a number of the challenges encountered by its predecessor, equivalent to offering an add-on fan to enhance thermal administration, refining the workflow expertise by way of the addition of instruments like waveforms, false shade and higher {hardware} connections, and thru enhanced capabilities, just like the addition of C-Log2 and twin recording.
The result’s a digicam that guarantees to carry out very nicely for each stills and video and will doubtlessly combine fairly seamlessly as a B-cam on a manufacturing utilizing Cinema EOS tools. In case you’re a critical video shooter and even an fanatic simply trying to experiment and develop your horizons, the R5 has a whole lot of potential. We’ll see the way it stands as much as real-world use as soon as we obtain a manufacturing copy, and stay up for testing the autofocus to see how nicely the expertise on the stills aspect of the digicam interprets to video.
