Found an answer on Epic for Indies discord (thanks Bent Vector). For me the fix was simple but unexpected - changing my bink video from 30fps to 24fps. At 24fps (1920x1080), my startup movie now plays correctly in a shipping packaged build (w/ UE5.3).
To help others who stumble across this I’ll post a full list of help that I received. Note that for me I did not have to match these settings exactly, but they may help someone else:
Project:
- Bink Buffer Mode: Stream,
- Bink Sound Track: Simple,
- I DO NOT have my movie included in packaging.,
Asset:
- Bink Buffer Mode: Stream Until Resident,
- Simple sound track,
- Start Immediately: UNCHECKED,
Also, you MUST put the bink file(s) in Content\Movies
