We're receiving reports of customers in Premiere v26.5 having glitching issues, such as green flashes, during playback and exports.

The issue appears to be specific to media that is:

Long GOP
Recorded in the MXF container
10-bit 4:2:2
Recorded using a Canon camera, including the EOS R5 C, EOS C50, EOS C70, EOS C80, and EOS C400

If you are having this issue with a file that doesn’t match this description, we are eager to hear from you.

We are currently investigating with a top priority to fix this. For now, the temporary workaround is to roll back to v26.3.2. Apologies for any frustrations with this and appreciate your patience while we investigate.

Thanks!
Katie

Hi all,

We have identified the cause of this problem and fixed it. A patch for v26 that includes this fix will be available very soon, likely in less than one week.

The fix is also now in Premiere Beta v27.0, build 57 or higher. While we do not suggest customers use beta for production, it is safe to install the beta alongside v26 if you would like to test the fix yourself.

Some customers in this thread have said that rolling back to a version of Premiere v26.x before v26.5.x did not fix the problem - even with the older version, green flashing was still seen in the media. If you’re experiencing this, please hold down the shift key and launch Premiere. In the Reset options dialog that appear, check the box to clear the media cache.

Regards,

Fergus

Issue Description:
Upon updating to Premiere version 26.5.0 (Build 99), I experienced severe playback performance issues. While the audio plays back perfectly fine and smoothly, the video track completely freezes, stutters, and outputs solid "green frames." This issue occurs consistently when trying to preview H.264 / HEVC video files on the timeline.

Disabling "H.264/HEVC hardware accelerated decoding" in Media Preferences acts as a temporary workaround. Rolling back entirely to a previous version (v26.4.0) resolves the issue completely out-of-the-box, confirming it is a regression specific to v26.5.0's hardware decoding engine.

System Specifications:

OS: Windows 11
GPU: Nvidia GeForce RTX 4070 SUPER
GPU Driver: Latest Nvidia Studio Driver
Premiere Version: v26.5.0 (Build 99)

Hello @kiwon291540894wxp

Thank you for your Bug Report. We are wondering if you would be willing to share a test file that is exhibiting this issue for you. If you can, I will DM you a private upload link to share with our engineers. It would be much appreciated. I’m glad you found the workaround of disabling Intel hardware-accelerated decoding in Media Encoder.

Hoping to help,

Amy

Are you on Mac or Windows? Especially if on Window 11, check your GPU driver! Windows will do it’s routine updates and sometimes that includes changing the GPU driver… and it doesn’t often choose wisely.

That’s the first thing to check.

Yes I have updated drives, the previous version of premeire was working just fine this version is the issue. I found a quick fix is to just use the older version but that still comes with limitations because Im not able to use the masking tools like in 26.

If you are on Windows and you recently had an update you need to see what I wrote about Windows and drivers a day ago… every time Windows does an update it MAY require an update of device drivers

Hey @Brave_photoa227 and @John T Smith

I moved the comments and Question over to a known issues post to make it easier to gather information and let everyone know workarounds and such. Right now, downgrading to 26.3 is the best workaround.

Also: please let us know what kind of footage you’re using. Compressed clips often lead to weird glitches and behavior.

Do not count on Windows to be fully up to date when it comes to device drivers
Go to the vendor site to be sure you have an updated driver for your graphic adapter
There have also been reports in the past that the latest driver is not the best driver

That’s a GPU issue. So what’s your hardware, GPU, GPU driver in use, and your media? Have you tried basic troubeshooting like checking your GPU driver to see if it’s current?
