R5 Mark II 8K 60 FPS sRaw M1Max MBP--Timeline Performance

Hi All:

I am considering purchasing a R5 Mark II for working with 8K 60 FPS sRaw on my M1Max MBP with 64 GB Ram 32 Core GPU. What is the timeline performance? Do I need to generate optimized media? Do I have to work in a reduced timeline playback resolution?

Thank you in advance.

Anyone tried this out?

Hi All:

I was able to get my hands on a R5ii and shoot 8K 60 FPS Raw lite--there is no 8K sRaw at 60 FPS. Timeline performance is good on an M1Max MBP16. Ultimately decided not to purchase the camera as I just cannot reconcile my dislike of externally zoomed long lenses. Looks like I am going Sony for the FE 200-600 f/6.3.

Even if you have a 4090 Machine, you aren't going to edit on a 8k timeline. Edit in 1080p and change to delivery resolution for color.

I fully expect 99% of people shooting in 6k+ are still delivering 4k. The extra resolution is there for cropping, rotation and sharpness. Don't deliver a 8k timeline unless someone is specifically asking for it and has a good reason.

Optimized media. No raw codecs have hardware acceleration like H.265 and PR (on apple silicon) does, so it is way more work to decode it. Resolve has the option to decode raw in lower quality to get around this. When I was experimenting with raw from my R5, these lower quality modes didn't work right, I don't know if it has since been fixed. (BM did just very recently post release notes about fixing the ISO bug that has been in canon raw for multiple years. )

So I could still see the need for PR proxies to edit Raw smoothly. Again you are only using these for edit and will go back to rushes for color, so make them 1080p PR Proxy or LT.



As other post said, 8k sraw isn't a thing in R5ii. Sraw is the horrible quality line skipped 4k raw, never use it. Use 8k raw.

Sadly Canon has 4k60 HQ on R5C but was unable to do it on the R5ii for some reason. So 8k raw is your only option for good 60fps (no 8k60 H.265 on R5c or R5ii).

Hi Zeb,

As I worked on setting up the R5Mark ii at the retailer I came to the conclusion that the term sRaw is not correct. In fact there is no sRaw on the camera. Only Standard and Lite. If I tried to set up 60 FPS in Standard Raw I was unable to get to 8K--only 4K. When I put the camera on lite Raw then I could get 8K. I think many are using the term sRaw incorrectly. Maybe individuals should start referring to LRaw for lite raw and sRaw for standard raw.

As I am not an experienced Canon user, please feel free to correct me.

The reason HEVC etc need hardware decode is they are almost always long GOP. Your computer needs to generate all the missing frames. It's not just uncompressing.

RAW actually ends up easier if your computer has the drive speed and space.

I don't remember what speeds Canon Raw needs but NRAW 8K 60 basically maxes out CFe gen 2. That means you need NVME for actual editing.

Two different things. Sraw is the line skipping to get you 4k raw from an 8k sensor.

You have two file size quality options for most of these as well, Lite (down arrow) and Regular. Presumably they don't have the card speed for 8k50/60 regular, you only get lite.



All kind of irrelevant as OP's real question is how much horsepower they need to edit the footage on mac.

In the description of the video below is a Google Drive link to R5 Mark II 8k/50 and 8k/59.94 material. I downloaded those and tried them on Resolve Studio 19.1.4 on a M1 Ultra Mac Studio 128GB, an M1 Max MacBook Pro 16 64GB, and an M4 Pro Mac Mini 48 GB.

It would play on an uncached 8k timeline, but using a 4k timeline was smoother. The M1 Ultra was better, especially if using any effects. However, the M1 Max and M4 Pro were usable, provided you stick to a 4k timeline and have proper expectations about render time to cache and export time.

8k/60 is a severe strain on almost any computer. The file data rate For Canon RAW is about 330 megabytes per sec. Compared to 4k/30, it is 4x the pixels per frame and 2x the pixels per second, or 8x the total pixels per second. In theory 8k/60 would require a computer with 8x the computational performance to have equal editing/rendering performance as on 4k/30.

So 8k/60 Canon RAW is not a casual decision. If I edited and graded that regularly, I would have an M3 Ultra Mac Studio, and even then, it would not be a brisk experience.

I give my 2 cents. At my Macbook M2 pro 16GB and 16GPU 8K 50fps Canon Raw light footage plays at 10 fps at 8K timeline and all cache and optimization disabled. According to this hierarchy https://www.cpu-monkey.com/en/cpu_benchmark-bench_11

you will get 10600/5300= 2 times more performance or little better because of more memory bandwidth.
20-26 fps expect

So 8k/60 Canon RAW is not a casual decision. If I edited and graded that regularly, I would have an M3 Ultra Mac Studio, and even then, it would not be a brisk experience.

Exactly, I was forced to order RTX 5090 for it
