P: Improved performance for Canon raw video formats

I wanted to know if others are having a similar problem of choppy playback when editing C70 RAW footage in premiere. I'll get about 2 seconds of good playback then it skips frames and gets choppy.

I've got the resolution set to 1/2 and High Quality Playback set to off.

This happens in Premiere 14 and 15 versions.

I'm using a maxed-out M1 Max MBP.

If I remove the canon lut, it plays back fine.

What do you think is going on?

Thanks for replying ... more data is more better.

I just tried the latest Beta (25.1.0 BETA (Build 15)) and the following video shows my result.

Playback is still unbearable at full resolution. With 1/8th resolution, I am able to smoothly play back, but my CPU is still at 100%.

This is with a M1 Max MacBook Pro 16" — not a small machine at all!

Here is a demo screen recording (keep an eye at the top of menu bar with the CPU graph. The left one shows the cores' usage, the 2nd one shows the history of CPU usage, 3rd one is the GPU utilization.

It's frustrating to wait so long for performant codec support. We buy powerful machines, use premium software, and can't efficiently work.

But did you try the beta?

Thank you for the update.  Its a bit disheartening that this is still an issue after all this time.  I recently tried playing back .CRM files directly in Davinci Resolve and I was blown away by how they play back perfectly at full res while using so little CPU/GPU resorces.  With Premiere Pro on my Apple M2 Ultra, it literally spikes all my CPU/GPU just to playback.  

Its a bit suprising.  These formats have been out for years and are from one of the big major camera munfacturers.  Hopefully this is finally adressed soon.

I know they've got three Canon log formats in the public beta ... are there any improvements there that help you?

That "ships" at MAX, under a month now.

I don't know what it will take to get better Canon raw support but I'm here to throw my hat in as well. I like editing in Premiere, but the incredibly slow speed when working with my C500 II and R5C raw files in Premiere has driven me over to Davinci. If we can't get support soon, I'll most likely end up making a complete switch over. I just can't continue to deal with the lack of support. It's been years. 

Thanks for the information, Fergus. It's good to be kept aware of what's going on.

Hi all, 

I have merged several threads regarding the performance of Canon's raw video format into this thread.

Currently, Adobe's video applications do not use the GPU on your computer to accelerate the playback of Canon raw formats. Performance may be acceptable on high-end Apple silicon Macintosh computers (M3 MAX or above) but is likely to be poor on other computers, even other Apple silicon computers and particularly when using footage that is higher frame rate than 23.98 and higher resolution than 4K. While we do support the updated Canon raw format of the Canon EOS R1, R6 Mark II, EOS C80, and EOS C400, we recognize that performance will be frustrating to customers of these cameras.  

While I don’t have a date to share yet, we do plan on adding GPU support in the future and I will update this post when that is available.

Regards,

Fergus

Hey Chris,

I'm still experiencing the exact same issues with the same computer and camera.

Did adobe ever get back to you with a solution? I have tried everything and I can't get the 5.9K raw to playback at all however 8K plays back fine?
