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:

Import Canon C50 Open Gate Cinema RAW Light (.CRM) footage into a project.
Add the clip to the timeline or preview it in the Source Monitor.
Play back the footage with the Video Renderer set to Mercury Playback Engine GPU Acceleration (Metal).
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.

Any update on this Adobe? It’s been almost half a year since the camera was released.

I’m a bit disappointed that the issue we pointed out last December was delayed. It seems that the thread or forum we were discussing about this issue was completely removed from your end.

If we don’t have a fix for this problem, it’s probably best to address it now rather than waiting.

Did the new update today fix this?

I shoot footage with the new Canon C50, whenever I upload the raw .CRM footage into the Premiere, the source monitor glitches and freezes immediately, ultimately it causes the entire program to crash.

Yes, I have spent far too long pulling my hair out over this issue too. You are right in that the only current solution is to revert back to 25.0

I’m getting the same purple artifact and, at times, the whole lower half of the frame blacked out even in premiere 25. I'm working off Premiere 25.6.4 (Build 5). Do I need to download an even earlier build of the premiere 25?

Yes - I uninstalled all Premiere and re-installed 25.0

The only solution. I hadn’t worked with Canon footage before, and it was all kinds of resolutions, so some were giving me that problem but not all I suppose depending on the codec. Canon isn’t exactly a niche brand so suprised Adobe has been so slow to fix this...or am I? 😉

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)

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!
