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.

        There was an update a day or two ago, seems to play the files now. I haven’t had a proper play with anything on a timeline though but the preview seems to work.

        Not fixed. Tried a C50 open gate raw file and a c400 OG raw file. I get a purple artifact on screen and it wont play back. (Shown is the c50 file)

            Have the same issue.  Another work around is to use DaVinci Resolve, it reads the files fine.  Hopefully Adobe fixes this issue as we’ve moved to Canon C50 for our workflow, and I don’t know how longer we can keep waiting when there are other options available.

            Issue - Unstable playback of Canon c50 Raw in Premiere 26. Creates glitches, both colored squares like this and blackout frames. Other Canon camera’s Raw play well.

             

            Steps to Reproduce - All you need to do is import it. Happens in source and program monitor. rendering does not help.

             

            Expected Result - It plays as normal.

             

            Actual Result - See attached image.

             

            Premiere Version - 2026

             

            OS - Sequoia 15.6.1

            Video Format: Happens in program and on export

             

            Happens in all projects. FWIW, these files play nicely in Resolve. Hoping there is an update to CC soon to fix this issue!
