Canon EOS R5- Things you need to know if you are recording video

I have read through all 919 pages of the Canon EOS R5 user manual so I could collate important information you may or may not know about the camera. If you are thinking about buying the camera with video as the primary purpose, then it may well help to have a read below.

Now, this is just information from the user manual and the reality is that real-world shooting conditions hardly ever mimic ideal shooting conditions that are listed in manuals. I haven’t shot with or even touched an EOS R5. This is not my thoughts or opinions on the camera, its just information listed officially by Canon that you may need to know.

If you have bought or are thinking about buying an R5 it is best to do your own testing and find out how the camera works in the conditions and environments that you will be using it in. Don’t rely on someone else’s advice because they may be testing the camera in situations or conditions that are different from how you will use it. You would have probably already seen a multitude of overheating tests where the results have been quite varied. This is why it is important to do your own tests. Ultimately only you can decide if a camera is right for you.

Video recording: Some things you need to know

  • By default, [AF : Movie Servo AF] is set to [Enable] so that the camera always keeps focusing
  • ISO speed cannot be expanded to L (equivalent to ISO 50) in movie recording.
  • Still photo shooting is not supported in movie recording mode. To shoot still photos, stop recording and change the [Shooting mode] setting to still photos first.
  • The remaining time displayed for movie recording is only a guideline.
  • Other devices may not play movies such as 8K, 4K, /FHD 59.94P/50P, or High Frame Rate movies normally, because playback is processing-intensive.
  • Apparent resolution and noise vary slightly depending on movie recording quality, cropped shooting settings, and the lens used.
  • From an 8K or 4K movie, you can select any frame to save to the card as a JPEG still image
  • Commercially available software may not be able to display RAW movies recorded by this camera. For compatibility information, contact the software manufacturer.
  • To prioritize gradation in highlights, set Canon Log to [On]. This is recommended for Cinema EOS and RAW movies.
  • Time-lapse movies cannot be recorded when the camera is connected to a computer with the interface cable, or when an HDMI cable is connected.
  • If you record something that has fine detail, moire or false colors may result.
  • If you perform AF with a USM lens during movie recording in low light, horizontal banding noise may be recorded in the movie. The same type of noise may occur if you focus manually with certain lenses equipped with an electronic focusing ring. Recording a few test movies is recommended if you intend to perform zooming during movie recording. Zooming as you record movies may cause exposure changes or lens sounds to be recorded, an uneven audio level, inaccurate lens aberration correction, or loss of focus.
  • Large aperture values may delay or prevent accurate focusing.
  • Performing AF during movie recording may cause the following kinds of issues: significant temporary loss of focus, recording of changes in movie brightness, temporary stopping of movie recording, or recording of mechanical lens sounds.
  • Any external microphones such as Directional Stereo Microphone DM-E1 (sold separately) connected to the camera’s external microphone IN terminal are used instead of the built-in microphones

Available shutter speeds in Manual mode vary depending on the frame rate of your specified movie recording quality:

It is interesting that when you are recording at 100P or 119.98P the minimum shutter speed you can choose from is 1/100 or 1/125 respectively. There may be times when for creative reasons you want to record slow motion at slower shutter speeds and not follow the 180-degree rule. On the EOS R5 that isn’t possible to do.


  • When outputting HDMI video 8K will be outputted at 4K.
  • The frame rate of HDMI video output when you are in 4K 119.98P or 100P mode is 59.94 fps or 50.00 fps respectively.

You can specify how movies are displayed as they are recorded via HDMI to an external device. The Movie output itself corresponds to the [Movie rec. size] setting.

The default setting enables movie display both on the camera screen and on the other device, via the HDMI output.

The second option allows for camera operations such as image playback or menu display to be shown on the other device via HDMI, and not on the camera screen.

The third mode deactivates the camera screen during output via HDMI, so that the screen is blank. Shooting information, AF points, and other information are shown on the external device via HDMI, but you can stop output of this information by pressing the <INFO> button.

Audio is also output via HDMI, except when [Sound rec.] is set to [Disable].

Time codes can be added to external device recording via HDMI. Time codes are added to HDMI video output. When [On] is set, [Rec Command] is displayed.

Notes about timecode over HDMI:

  • Time codes are not added to HDMI video output when you record High Frame Rate movies with [Count up] in [Time code] set to [Free run].
  • To determine compatibility of external recording devices with [Time code] and [Rec Command] functions, check with the device manufacturer.
  • Even with [Time code] set to [Off], external recording devices may add time codes to movies, depending on their specifications. For details on device specifications relevant to adding time code to HDMI input, check with the device manufacturer.

Image Crop

The movie image area varies depending on factors such as movie recording quality and cropped shooting settings and the lens used.

Screenshot 2020 08 02 at 2 28 44 PM

Recording of 8K, 4K, and High Frame Rate movies is not supported with EF-S lenses, or with [Movie cropping] set to [Enable].

Recording with Movie digital IS activated further crops the image around the center of the screen.

8K, High Frame Rate, and 4K HQ movies cannot be recorded with movie cropping enabled.

What cannot be recorded to SD cards?

The following files cannot be recorded to SD cards:

• RAW movies
• 8K ALL-I
• 4K 119.9/100.0 fps (High Frame Rate movies)
• 4K ALL-I HEVC (YUV422, 10-bit)
• 4K 59.94/50.00 fps ALL-I H.264 (YUV420, 8-bit)

If you try and press the movie record button in any of these modes with just an SD card in the camera it will not start recording.

Card Recording Options

On the EOS R5 you have several options available as far as how recordings are done when you are shooting video:

Records movies to the card selected in [ Record/play]

Auto Switch Card
Same as [Standard], but recording ends when the card becomes full. When you resume recording, the camera switches to the other card for recording. A new folder is created after switching cards. Auto Switch card will only work when you are recording in certain resolutions and framerates. Please be aware that if you are recording in any of the following modes and your CFexpress card fills up, it is not possible to keep recording to the SD card slot:

• RAW movies
• 8K ALL-I
• 4K 119.9/100.0 fps (High Frame Rate movies)
• 4K ALL-I HEVC (YUV422, 10-bit)
• 4K 59.94/50.00 fps ALL-I H.264 (YUV420, 8-bit)

1 RAW, 2 MP4
For each recording, a RAW movie is recorded to one card and an
MP4 movie to the other card, both with the same file number. When one card becomes full, recording no longer becomes possible.

Just a note: If you set the power switch to <OFF > while an image is being recorded to the card, [Saving…] will be displayed and the power will turn off after the recording finishes. This is a safety feature to make sure that a recording isn’t lost if you accidentally power the camera off.

What cards are supported?

Screenshot 2020 08 02 at 2 33 17 PM

Above you can see what type of SD cards can be used and what resolutions and framerates they can record.

High Frame Rate Recording

You can record 4K movies at a high frame rate of 119.9 fps or 100.0 fps. The maximum recording time per movie is 7 min. 29 sec.

Here are some things to note about high frame rate recording:

  • Sound is not recorded in High Frame Rate movies.
  • Time code display during movie recording advances 4 sec. per second.
  • Because High Frame Rate movies are recorded as 29.97 fps/25.00 fps movie files, they are played in slow motion at 1/4 speed.
  • ISO speed can be set within ISO 100–12800. Note that ISO expansion is not available.

SO speed can be set within ISO 100–12800. Note that ISO expansion is not available.
The frame rate of HDMI video output is 59.94 fps or 50.00 fps.

The third one may seem very odd. You can only record high frame rate movies at 29.97 fps/25.00 fps movie files.

Canon Log & Picture Profiles

You can only record in Canon Log on the EOS R5, Canon Log 2, and Canon Log 3 are not supported (this may change in the future).

Canon Log offers a dynamic range of approx. 800% at ISO 400 or higher. Manually setting the ISO speed to 100–320 will reduce the dynamic range.

Here is what Canon says about Canon Log image quality:

  • With Canon Log, movies may be affected by horizontal banding, depending on the subject or shooting conditions. Record a few test movies and check the results in advance. In particular, noise may become more noticeable if you enhance the contrast when color-grading your movies.
  • With Canon Log, skies, white walls, and similar subjects may be affected by noise or uneven gradation, exposure, or colors.
  • Horizontal banding is more likely to occur when recording somewhat dark, flat subjects. This image noise may even occur at relatively low ISO speeds around ISO 400.
  • If noise is noticeable, try recording under brighter conditions and adjusting brightness in color grading. Noise can also be reduced by recording at ISO speeds lower than ISO 400, although dynamic range is narrower.
  • With Canon Log, autofocusing may be more difficult for subjects under low light, or for low-contrast subjects.
  • Noise may appear at image edges if [Peripheral illum corr] in [ : Lens aberration correction] is set to [Enable] when Canon Log is set.
  • ISO 100–320 is not available when recording RAW movies with Canon Log set.

With Canon Log, autofocusing may be more difficult for subjects under low light, or for low-contrast subjects.
Noise may appear at image edges if [Peripheral illum corr] in [ : Lens aberration correction] is set to [Enable] when Canon Log is set.
Canon Log 2 and Canon Log 3 are not supported.
Histograms of images captured with [Canon Log] set to [On] are not based on images as converted for View Assist display. Image areas shown in gray in the histogram roughly indicate signal values that are not used.
ISO 100–320 is not available when recording RAW movies with Canon Log set.

You can use a View Assist feature when shooting in Canon Log. View Assist is basically just a LUT. Setting this feature to [On] does not affect movies recorded to the card, they are still recorded as Canon Log. Similarly, the HDMI video output will also be Canon Log and it isn’t outputted with View Assist characteristics.

[Color space] can be set when [Canon Log] is set to [On] and [Color Matrix] to [Neutral]. Choose [BT.709] or [BT.2020] as the color space for HDMI output.

Screenshot 2020 08 02 at 2 56 34 PM

You can also select what Color Matrix you want to use, this allows you to specify how colors are reproduced.

You have two choices in the Color Matrix menu:

Cinema EOS Original
Reproduces colors equivalent to those of the EOS-1D C.

Reproduces colors similar to actual subject colors.

You can also make changes to a setting called Characteristics. This allows you to make changes to sharpness, saturation, and hue.

As far as Picture Profiles are concerned you can customize a wide array of profiles if you don’t want to shoot in Canon Log.

The color tone will be adjusted automatically to suit the scene. The colors will look vivid for blue skies, greenery, and sunsets, particularly in nature, outdoor, and sunset scenes.

The image looks vivid, sharp, and crisp. Suitable for most scenes.

For smooth skin tones, with slightly less sharpness. Suited for close-up portraits. Skin tone can be adjusted by changing [Color tone] as described in Settings and Effects.

For vivid blues and greens, and very sharp and crisp images. Effective for impressive landscapes.

Fine Detail
For detailed rendering of fine subject contours and subtle textures. The colors will be slightly vivid.

For retouching later on a computer. Makes images subdued, with lower contrast and natural color tones.

For retouching later on a computer. Faithfully reproduces the actual colors of subjects as measured in daylight with a color temperature of 5200K. Makes images subdued, with lower contrast.

Creates black-and-white images.

User Def. 1–3
You can add a new style based on presets such as [Portrait] or [Landscape] or a Picture Style file, then adjust it as needed ( ). With any User Defined Picture Style that has not yet been registered, pictures will be taken with the same characteristics settings as with the default settings of [Standard].


When recording in any of the HDR modes please note the following:

  • HDR movie recording is not available with [ : IS (Image Stabilizer) mode] set to [Digital IS], or when set to [ : Time-lapse movie], [ : Highlight tone priority], [ : Canon Log settings], or [ : HDR PQ settings].
  • Since multiple frames are merged to create an HDR movie, certain parts of the movie may look distorted. This is more noticeable in handheld recording affected by camera shake, so consider using a tripod. Note that even if a tripod is used for recording, afterimages or noise may become more noticeable, compared to normal playback, when the HDR movie is played back frame-by-frame or in slow motion.
  • Image color and brightness may change significantly for a moment if you change settings for HDR movie recording. Also, the movie will not be updated for a moment, and the frame stops momentarily. Be aware of this when recording movies to external devices via HDMI.

Vertical Video Metadata

If you are shooting vertical video on the EOS R5 you can go into the menu and Enable rotate info. This will burn in metadata into the file so that the files will be played back correctly on the device you are viewing it on.

Play movies on smartphones or other devices in the orientation in which they were recorded.

Play movies horizontally on smartphones or other devices, regardless of the recording orientation.

Now, just a couple of notes:

[Add rotate info] is not available for RAW or MP4 files when the movie recording format is RAW or RAW + MP4.

Movies are played horizontally on the camera and via HDMI video output, regardless of whether you have rotate info enabled or disabled.

Movie Self-Timer

Screenshot 2020 08 02 at 3 12 54 PM

On the EOS R5 there is a Movie Self-Timer function where you can set a recording to start 2 seconds or 10 seconds after you hit the record button. This is useful for people who are shooting themselves.


[IS mode] is not displayed when an IS-equipped lens is attached. If you attach an IS equipped lens then the [IS mode] is always activated and can’t be turned off.

Other things to note:

  • Movie digital IS will not function when the lens’s optical Image Stabilizer switch is set to < >.
  • With non-IS lenses, setting [ Digital IS] to [On] or [Enhanced] also sets [IS mode] to [On].
  • Although movies can also be recorded with Movie digital IS when using EF-S lenses or movie cropping, the image area is further reduced.
  • With a lens whose focal length is longer than 1000 mm, Movie digital IS will not function.
  • Stabilization by Movie digital IS may be less effective at some movie recording sizes.
  • The wider the angle of view (wide angle), the more effective the image stabilization will be. The narrower the angle of view (telephoto), the less effective the image stabilization will be.
  • When using a tripod, setting Movie digital IS to [Off] is recommended.
  • Depending on the subject and shooting conditions, the subject may blur noticeably (the subject momentarily looks out of focus) due to the effects of the Movie digital IS.
  • Consider setting to [Off] when using a TS-E lens or fish-eye lens.
  • Since Movie digital IS magnifies the image, the image looks more grainy. Noise, dots of light, etc. may also become noticeable.

Magnified View When Focussing

To check the focus when the AF method is other than [ +Tracking], you can magnify the display by approx. 6× or 15× by pressing the <Magnify > button (or tapping the Magnify button).

The magnification is centered on the AF point for [Spot AF], [1-point AF], [Expand AF area: ], and [Expand AF area: Around] and on the Zone AF frame for [Zone AF], [Large Zone AF: Vertical], and [Large Zone AF: Horizontal].

Autofocusing is performed with a magnified display if you press the shutter button halfway when set to [Spot AF], and [1-point AF]. When set to AF methods other than [Spot AF] and [1-point AF], autofocusing is performed after restoring normal display.

With Servo AF, if you press the shutter button halfway in the magnified view, the camera will return to the normal view for focusing.

In magnified view, peaking display is not shown.

Recording Voice Memos

On the EOS R5, you can record voice memos that get captured as WAV audio files, but unfortunately, this function isn’t supported when capturing video.
