Premiere Pro 26.2 - Native Camera Shake effect causes Program Monitor offset in Multicam view while export renders correctly

Hi Jonathan,

Thank you for the response. I can clarify exactly what I mean by “offset” and provide a reproducible example.

By “offset”, I mean that when the native Camera Shake effect is applied, the image becomes horizontally displaced inside the Program Monitor when using Multicam View. Part of the video moves outside the visible area of the Program Monitor and a black area becomes visible on the opposite side. It looks as if the video has been panned significantly to the right.

The important part is that this only affects the Program Monitor preview. The exported video is rendered correctly and has no offset or black area.

Reproduction steps

1. Create a completely new Premiere Pro project.

2. Create a new sequence.

3. Add a single video clip to the timeline.

4. Apply the native Camera Shake effect from Premiere Pro to the clip.

5. Open the Program Monitor.

6. Switch the Display Mode from Composite Video to Multicam.

7. The video becomes horizontally offset and part of the image disappears outside the visible area.

8. Switch back to Composite Video and the image immediately displays correctly again.

9. Export the sequence: the exported file is also completely correct.

I also tested the following:

• The issue occurs in a completely new project.

• It occurs with a single video clip, without a Nest.

• It also occurs when the Camera Shake is applied to a Nest inside a Multicam workflow.

• The issue is not related to my original projects.

• Changing Program Monitor playback resolution from Full to 1/2, 1/4 and 1/8 does not change the behavior.

• Enabling High Quality Playback does not change the behavior.

• Composite Video displays correctly.

• Multicam View displays incorrectly.

• Rendering the timeline does not fix the Multicam preview.

• The exported video is always correct.

• I tested the native Transform effect instead of Camera Shake. Transform works correctly in Multicam View and does NOT cause the offset.

• I previously used Video Copilot Twitch/Jitter for this type of shake and it worked correctly in the Multicam preview.

So at this point the issue appears to be specifically related to the native Camera Shake effect + Multicam Program Monitor preview.

System

MacBook Pro M1 Pro, 16 GB RAM
macOS 15.7.7
Premiere Pro 26.2
Mercury Playback Engine GPU Acceleration (Metal)

Regarding 26.3: I will also test the latest 26.3 build and report back whether the issue persists.

Please let me know if you need any additional information or a specific project/clip to reproduce it.

Best regards
