P: Improved performance for Canon raw video formats

Dear Adobe Team,

 

I hope this message finds you well. I wanted to take the opportunity to share some feedback on my experience using the Canon EOS R5C with Premiere Pro. While I have been utilizing raw files more frequently, I have noticed that the software is struggling with processing these files during playback. Even without any effects or color adjustments applied, Premiere Pro seems to lag significantly, but particularly with small effects like lumetry color.

 

Upon playback, my CPU usage spikes to 100% on all cores, while the GPU remains relatively calm at around 50%. This makes it nearly impossible to smoothly playback footage at full resolution. When I reduce the playback resolution to 1/16, it does play through, but this compromises the quality and is not an ideal workflow.

 

Using proxy files is an option, but it becomes limiting when I need to make more intricate adjustments such as color grading or noise reduction.

 

With these concerns in mind, I would like to inquire if it is possible for Adobe to improve the processing of Canon RAW Light files in Premiere Pro, so as to alleviate the heavy strain on system resources.

To provide some context, I am working on a powerful M1 Max 64GB machine which handles 4k HEVC flawlessly. However, the Canon RAW files seem to overwhelm the system.

 

I genuinely appreciate any insights or guidance that you could offer on this matter. It is my hope that Adobe can continue to enhance the render engine to address these challenges.

 

Thank you for your time and consideration.

 

Best regards,

Chris

    Here we are, over three years later, and .CRMs are more or less unviewable, uneditable, etc. on Premiere. So disappointing.

    Count me in as yet another longtime Premiere user who opens Resolve more and more often each project.

      I have a possibly serious problem on my hands:

      My main client has moved heavily into shooting on the C200 and editing with its resulting CRM files. They say CRM edits just fine off of external SSDs on their (Mac) systems. However, when I try to work with these files on my main system, it's a nightmare even off of my internal M.2 SSD with 3GB/s read speeds. Playback is a choppy, slow slog and so is all editing / effects work / coloring. My machine eats up any other 4K format just fine so far, but CRM is a no-go at the moment.

      To top it off, Premiere can't seem to create proxies for CRM footage and the Canon Cinema RAW developer utility creates just unusably large DPX files (and is way too slow). ProRes is of course out of reach on Windows. The client wants to have a streamlined workflow (not creating redundant ProRes on their Macs) as they have no problems with CRM, and who could blame them.

      My system is this:
      Win 10 Pro 64bit

      Intel i7-6850K @ 3.6GHz

      64GB RAM

      NVIDIA GeForce GTX 1080 Ti

      Samsung SSD 960 EVO (for the CRM files)

      I would expect to be able to play CRM files on a timeline without any effects and at 1/4 resolution?

      Any help, anyone?

        Hi,

        Your hardware specs seems to be OK; similar to my machine.

        I have had good experiences editing CRM files from C200 in CC2018. Have not had a chance to use them in CC2019.

        Can you see if it works in CC2018?

        Let me know if this works.

        Richard

        Thanks for the speedy reply and sorry, should have specified: I'm still on CC 2018.

        I've been too busy to risk upsetting the apple cart by installing anything new.

        I guess I'll try 2019 then, now that you've reminded me of the obvious - not holding my breath but what have I got to lose at this point?

        Edit:

        Well, I installed CC 2019, created a fresh new project, imported two CRM clips and created a sequence from one of them.
        The same deal - incredibly choppy playback at 1/16(!) resolution.

        Edit 2:

        I also installed the free version of Resolve, and with what little I could do with it, it seemed to almost completely eradicate the problem: almost flawless playback at full resolution, with some quick color correction applied. So as far as processing power is concerned, my rig can easily handle it, as expected.

        Something in Premiere / its interaction with my system seems to be messed up.

        Edit 3:
        Well, CC 2019 did bring with it the ability to create proxies out of the CRM files. I think my existing version of Media Encoder had some problem with it, but now it seems I can create DNxHD-proxies and based on a quick test they work smoothly as ever. Takes a couple of hours, but at least this would get me back to editing instead of gnashing teeth.
