Brightness issue on Firefly Video
Over the last few days, Adobe Firefly Video has started producing noticeably brighter videos from the same starting images I previously used successfully.
The generated video becomes brighter shortly after playback begins, then darkens again towards the end. The exported video has the same problem, so it is not limited to the preview.
I have tried changing the prompt to specify constant exposure and lighting, disabling prompt enhancement, and using static camera motion, but none of these fixes the issue.
Previously, the same images and workflow produced videos that preserved the original image's darker exposure and colour grading.
Could you confirm whether there has been a recent change or known issue affecting exposure consistency in the Firefly Video model?
