Canon EOS R5 8K RAW Questions

1. I'm assuming when shooting 8K RAW, the camera shoots DCI from the 3:2 area of the sensor?

2. Are there aspect ratio markers? If not, can I frame the shot with 8K UHD since it's 16:9 and then record in 8K RAW? Then I'll just drop in post-processing to get the same view if I was allowed to record 8K UHD in RAW?

3. It's been a while since the R5 was released. Has the recording time for 8K RAW improved?

4. I read that the grid and electronic level isn't available in 8K DCI? Is that true? I hope it's not. I would love to be able to impose a rule of third grid on the screen to help with composition and use the electronic level. Is this disabled for all movie modes?

Re: Canon EOS R5 8K RAW Questions

I'm surprised nobody who has a camera has answered.

The R5 can record 8K DCI and 8K UHD. If you want only UHD select the U option. But I'm just going by the manual.

1. In standard shooting mode you can only shoot 8k RAW in DCI mode, you can shoot 8k UHD but will be encoded in All-I not RAW.

2. Wouldn't it be better to record in DCI do this in post?

3. When the R5 was original released the biggest issue wasn't the recording time per se (15minute segments, estimated to be about 20 minutes, though I get closer to 35mins) but the cool down time required to allow the camera to reshoot once that time was exhausted. Suggestions were that the sensor to measure the ambient temperature to prevent overheating was disabled and so regardless of external factors the camera needed about an hour turned off before you could record again. With the updated firmware, this sensor seemed more effective, not only was repeated recording time extended but also the time to cool down once camera overheated was significantly improved, dependent on the environment temperature you could start reshooting in a few minutes.

In real world usage though the overheating isn't half as bigger a deal as the internet made it out. Unless you live in a hot climate or you want long continuous recording, post firmware update my camera rarely overheated to the point where it stopped recording. For vlog or b roll (basically segmented shooting where you're hardly ever shooting beyond a few minutes at a time) as long as I turned camera off during setups etc I could pretty much shoot all the time. The bigger problem is usually storage. I have 2 x 1tb angelbirds cfexpress cards and a 512gb sandisk. I still end up having to occasionally transfer files to laptop mid shoot.

4. Electronic level and grid is available in 8k DCI as you frame, unfortunately though they seem to disappear when you start recording video, although this is a canon quirk in all modes not just 8K, its hopefully something that can be rectified with a firmware as a lot of people have made noise about it.

Advice - If you're going to shoot 8k RAW I recommend you turn on the option to record 4k mp4 proxies to the SD card, this helps greatly with editing workflow, I use the mp4's for timeline composition, then turn to the 8k raw for colouring.

Just a quirk to be aware of, if you turn on canon log in the normal video menu, the proxy files will be in h265 encoded canon log files, these are just as difficult to edit as 8k Raw. If you turn off canon log, the proxy is recorded as 4k H264 IPB, easily editable in most decent spec computers.

I agree with FourSite that RAW on the R5 means recording everything the camera generates from the sensor that means UHD and DCI is obtained only as a cropped version of RAW in POST.

I also strongly recommend you turn on the option to record 4k mp4 proxies to the SD card, this makes it practical on a fast computer to edit workflow using the 4K proxy without glitches using the mp4's for timeline composition and then turn to the 8k raw for coloring. I doubt many supercomputers can edit the 8K directly without the proxy. Creating the proxy in camera saves a great deal of workflow time and is a awesome feature. I rarely have use for 8K RAW but is nice to try. It noteworthy how excellent the 4KHQ quality is and also noteworthy how good the 4K30 crop movie mode (Super 35) mode is as it is 5.1 oversampled and has more detail than the 4k30 standard mode.

Both 4K30 standard and 4k30 crop mode have no thermal time restriction limits. There is 30minute timer but it is possible to restart immediately and repeating also long as the camera has power. You can also use a $500 Ninja V recorder on the HDMI output to record without thermal time limits in 4K30HQ mode and using this recorder bypass all timers and time limits. I used this several times for 90 minute 4K30HQ recording sessions.

If I want to record in 8K RAW, how can I frame it for the 8K UHD area? This way it'll make things easier to crop via post-processing.

When shooting stills you'll get 8192 pixels X 5464 pixels image in 3:2 using all the sensor's area . When you shoot 8K RAW it will be DCI format : 8192 pixels X 4320 pixels . In other words , when you shoot 8K RAW , the sensor's full width we'll be recorded , but 572 pixels on the top and the bottom won't . The field of view will be the same , but when compared to a still image , the top 572 pixels and the bottom 572 pixels will be cut cut for the recorded video file . Is it what you wanted to know ?

I still haven't edited the 8K files I've recorded so far , but I was able to take a look at them using DaVinci Resolve 17 .

Yes, that's what I wanted to know. What about 8K UHD? It's too bad that it can't be recorded in RAW. What I had described earlier, will it work to maintain the framing if I want to record in RAW and output in 8K UHD?

Re: Canon EOS R5 8K RAW Questions

DCI 8K is 8192 x 4320
UHD 8K is 7680 x 4320,
You can crop the DCI to UHD, just know you're going to lose 512pixels either from the top or bottom or a combination of both. As long as you don't frame you shot is a way where you want what's on both the top edge of the frame AND the bottom edge of the frame you should be fine.

Let's pretend I won't be moving the camera. It's on a tripod and already set properly for the framing.

Are there aspect ratio markers? If not, can I frame the shot with 8K UHD since it's 16:9 and then change the recording to 8K RAW? Then I'll just drop the video in a post-processing app, crop to 8K UHD since it's 16:9, and still get the same view as if I had filmed using 8K UHD mode in the camera? I'm assuming the framing and the view will be the same, but obviously I'll get a RAW video file, which is what I want.

When you switch from stills mode to 8K DCI RAW video mode , the top and bottom 572 pixels will be blacked out , won't be shown . The field of view stays the same , but the top and bottom 572 pixels , when compared to a still image , won't be shown in the video file . There are no markers , it's like when you watch those original Hollywood movie files , much wider than 16:9 aspect ratio ,  there are those black stripes on the top and bottom of your 3:2 aspect ratio rear LCD or viewfinder . 8K RAW DCI is 17:9 aspect ratio , or , is 512 pixels wider than 8K UHD .

I appreciate your explanation, but do you understand what I'm asking? For starters, I'm not asking about stills mode at all.

1. Does 8K UHD have the same field of view as 8K DCI RAW?

2. Let's pretend I won't be moving the camera. It's on a tripod and already set properly for the framing. No panning whatsoever. Can you read the example that I put above again? From my perspective, it seems pretty clear as to what I'm asking. Maybe we're not on the same page. I'll emphasis again as to why I want to do that and that is to obtain an 8K video file, but framed and composed properly for an 8K UHD screen. I don't know how else to ask this. If I have the EOS R5, I would just test this myself rather than asking. I've asked a number of times already in this thread and it doesn't seem like anyone here know the answer.

If I have the EOS R5, I would just test this myself rather than asking. I've asked a number of times already in this thread and it doesn't seem like anyone here know the answer.

Help?

I think I understand what you are asking here, unfortunately when shooting in 8K Raw it's DCI, you have to manually frame for UHD, there aren't any guidelines as its specific ask and I'm not sure of any cameras that shoot in DCI with guidelines for UHD. You're going to have do some guess work or as a quick fix maybe draw your own guidelines on a screen protector and use that,

Can I frame the shot with 8K UHD movie mode since it's 16:9 and then change the recording to 8K RAW? Then I'll just drop the video in a post-processing app, crop to 8K UHD since it's 16:9, and still get the same view as if I had filmed using 8K UHD mode in the camera? I'm assuming the framing and the view will be the same, but obviously I'll get a RAW video file, which is what I want.

I'll try this for you later to see if there is an aspect change that breaks the framing.

My gut feeling is that there shouldn't be any difference, but I can't test this myself since I don't have this camera yet.

Just had a mess about, in a non scientific way, put camera on tripod in a room scene, recorded 8K DCI RAW, then 8K UHD ALL-I.
The UHD seems zoomed in with a say 2-3% crop from the top, but a much more significant crop from the sides, say 5% from the left and right.

Unfortunately had household chores so couldn't extract videos and post screenshots for comparison but will at a future date.
