Hi WritingMate Support,

I'm experiencing an issue where video generation gets stuck at 0% progress and never completes.

Details:
- Model: sora-2
- Size: 720x1280
- Duration: 12 seconds
- Using inputReference (base64 image)

Example video ID that got stuck:
video_6a1aba8b7e188191b57f89a77a75df0604ab6a7d8898ed20

The job stays in "in_progress" status indefinitely with 0% progress and no error returned.

Questions:
1. Is there a known issue with sora-2 + inputReference?
2. Is there a file size limit for inputReference?
3. What is the expected processing time for a 12-second video?
