Severe visual glitch (pink/purple block covering the bottom half of the frame) during playback of Canon C50 Open Gate .CRM files.

Issue: Severe visual glitch (pink/purple block covering the bottom half of the frame) during playback of Canon C50 Open Gate .CRM files.

Steps to reproduce:

  1. Import Canon C50 Open Gate Cinema RAW Light (.CRM) footage into a project.

  2. Add the clip to the timeline or preview it in the Source Monitor.

  3. Play back the footage with the Video Renderer set to Mercury Playback Engine GPU Acceleration (Metal).

  4. Here is screen capture
    https://drive.google.com/drive/folders/1fzr9rO6zlH1kBaeyd0443lkYmAFZI54l?usp=sharing

Expected result: Smooth and accurate playback of the RAW footage without any visual artifacts or color distortion.

Actual result: A massive pink and purple distorted glitch appears, covering the lower half of the video frame during playback.

Workaround found: Downgraded to Adobe Premiere Pro version 25.0, where the footage plays back correctly without any glitches. Alternatively, in version 26.0.1, switching the Renderer in Project Settings to "Mercury Playback Engine Software Only" temporarily removes the glitch, but significantly degrades playback performance.

Adobe Premiere Pro version: 26.0.1 (Bug present)

Operating system: macOS Tahoe Version 26.3

System Specs: MacBook Pro 16-inch (2023), Apple M2 Pro, 16 GB RAM.

Video format: Canon C50 Open Gate Cinema RAW Light (.CRM)

Comparative information: The hardware decoding (Metal) fails specifically on Premiere Pro 26.0.1 with Apple Silicon (M2 Pro). Rolling back the software to version 25.0 resolves the issue completely. This indicates a potential bug in the recent 26.0.1 update regarding how the Metal GPU acceleration handles this specific Canon RAW format.

      Hi ​@PJ_THAILAND 
      Welcome to the Premiere community. Thank you for taking the time to report a problem. We are currently working to fix the issue with playback performance on the Canon C50 Open Gate Cinema RAW Light. As a temporary workaround, some users have been transcoding the media before importing it into Premiere. We will keep the community updated on progress and when a fix is available. 

      Here to help.

      I’ll check this out when I can get back to my computer. Doesn’t mention c400 open gate which also had a problem. I hope it’s part of it.

      Tested both Canon C50 and C400 Open Gate clips. no artifacts or color bars at the bottom. Plays back smooth at ½. I got a few drop frames in full res playback (prob  my comp) 

      Looks like after 6 months they are addressing the problem. I’ll see if I have any issues.

      Even google AI suggests the switching to Resolve. Come on Adobe, are you trying to speed up your demise?

      You’d figure we wouldn’t still be here commenting. I’d suggest pressuring your favorite creators with any following to say something. Seeing as the problem will only continue with the R6 V being announced. 

       

      Very frustrating. Prob will move NLE’s after I clear my queue and can learn another like I do know premiere.

              Can we get an actual update on this issue? It is a huge problem that Premiere can’t handle Canon’s raw files. This should be handled with a fire alarm all hands on deck code red seriousness. I’m shocked to see no real updates on a major problem that's been around for quite some time.

                  As a researcher, I use the Canon EOS C50 as my primary camera for my PhD research in Artistic Studies – Film and Image at the University of Coimbra. The critical bug generating artifacts and glitches during the decoding of Cinema RAW Light (.CRM) files has made my native Premiere workflow completely unviable for months.

                  I have been following this thread since last year, and the lack of resolution is alarming. In April 2026, I attended NAB Show in the US and spoke in person with a senior engineer at the Adobe booth. He confirmed what many of us already suspected: there is no ETA whatsoever for a fix.

                  During the same event, in conversations with Canon’s technical representatives, I got the strong impression that the issue has an architectural root cause: Adobe apparently opts for a proprietary decoding pipeline for .CRM files rather than using the native SDK provided by the manufacturer. Not coincidentally, DaVinci Resolve — which uses Canon’s native engine — processes the exact same files without any issues.

                  The continuity of my PhD research depends on a functional tool. I am being forced to pause my research, purchase a DaVinci Resolve license, and seriously compromise my academic timeline in order to learn an entirely new editing platform — all as a consequence of Adobe’s architectural decisions, not an insurmountable technical limitation.

                  I am directing this question to the Product Managers and Engineers responsible for this area: what is the real barrier to adopting Canon’s native SDK on macOS? A camera format of this significance cannot continue to be left broken across multiple consecutive software releases.

                      After 16 years of adobe products I am switching to Resolve. There’s no excuse to not be able to fix an error for this long. No updates, higher price. I’ve cancelled all my adobe products. Ridiculous and disappointing. Hey but at least they have ai clip extender!! GIVE ME A BREAK
