Premiere can't properly decode latest Google Flow model (Omni Flash) video outputs without introducing random artifacting.

On May 19th, Google added a new model, Omni Flash, to their Video AI generator, Flow. The latest versions of Premiere Pro (26.2.2 Build 3) and After Effects (26.2.1 Build 2) as of 05/22/26 are not properly decoding the codec used for the video outputs from this latest model. Obvious but randomly placed video artifacting is being displayed in both the preview and outputs from Premiere Pro and After Effects that are not being displayed in other applications or programs such as VLC Player, DaVinci Resolve, etc. I tried both the latest Game Ready as well as a clean install of the latest Studio Driver from NVidia for my 4080S but had the same results.

@yuki_0699 Thank you for sending along some test footage to Adobe. Initially I transcoded in another NLE that doesn’t exhibit this issue. Then in Pr I disabled hardware accelerated decoding. My GPU and CPU are both fairly recent and beefy so it hasn’t been too much of a drag on my workflow, but obviously it would be ideal to have this fixed for those who don’t have strong CPUs.

Hi Brad,

Thank you for sharing your findings.

It's really helpful to hear what worked for you.

I hope Adobe can fix this issue soon, since it seems to affect multiple NVIDIA users.

Thank you again for your help!

@yuki_0699 Thank you for your system specs. It helps us in identifying the causes of these playback issues.

I am wondering if this is related to another bug we are working on. Could you try setting in your Program Monitor the resolution to Full instead of the default ½? Let me know if this resolves the playback glitches.

Aside from that, if either you or @Alchemist Brad is willing to share a problematic file with us to further investigate, I would be happy to DM you a private link to upload.

Hoping this helps,

Amy

Thank you for your reply. I tested the Program Monitor resolution at Full, 1/2, and 1/4. Unfortunately, the issue occurs at all resolution settings. The random block artifacts still appear during playback and export. The artifact locations continue to change every playback and every export. I would be happy to share a problematic Omni Flash video file for investigation. Please send me a private upload link. Thank you.

I have the same issue.

My environment:

- Adobe Premiere Pro 26.3.0 (Build 93)
- Windows 11 Home 64-bit
- NVIDIA GeForce RTX 5070 12GB
- NVIDIA Studio Driver 610.62
- AMD Ryzen 7 7700
- 32 GB RAM

The original Google Flow (Omni Flash.) video files are completely clean.

Random block artifacts appear during playback in Premiere Pro, and the artifact locations change every time I play the timeline.

If I export the same timeline multiple times, the artifacts appear in different locations each time.

I tested the following:

- Disabled hardware decoding
- Software encoding
- Cleared the media cache
- Updated to the latest NVIDIA Studio Driver
- Converted the Omni Flash. clips to ProRes (no improvement)

Kling and Seedance videos do not show this issue.

One important finding:

The issue becomes much more frequent with longer timelines (around 12 minutes).

As a temporary workaround, splitting the project into approximately 3-minute sections and exporting each section separately avoids the artifacts.

I hope this information helps reproduce and investigate the issue. Thank you.

@yuki_0699 thank you so much for the test footage. We were able to recreate the Random glitches on PC’s with NVIDIA only.

We were able to use Media Encoder 26.3.1 to re-wrap the clips to H264 Match Source Highest Bitrate and could not get the glitch to come back in Premiere 26.3, if you want to try that on your end.

If the glitch persists, you can also try forcing Media Encoder and Premiere to use your dedicated GPU in your System → Display → Graphics settings. Make sure the Apps are added here and you should be able to change it with a dropdown

I’ll pass this on to our formats team to see why Omni Flash isn’t supported natively on PCs.

Thank you for your help!

Hi Amy,

Thank you very much for reproducing the issue and for investigating it.

I really appreciate you sending this to the engineering team.

I'll try the Media Encoder 26.3.1 workflow and the dedicated GPU setting you suggested.

Thank you again for your help!

Hello @Alchemist Brad,

Welcome to the Adobe Community Forums. Thank you for bringing this to our attention. If you’re willing to share one of these files to assist in troubleshooting on our end, we would be much appreciative. Let me know if this is something you are willing and able to do and we can work out the logistics.

The Studio Driver is certainly recommended and that was an excellent trouble shooting step.

Hoping to help,

Amy Stuvland
