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

​@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

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.

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
