Not sure why this was marked as solved with such a basic answer… anybody knows that you need to specify a camera, the answer is misleading to a basic solution LOL
I have the same issues and camera cut tracks are set correctly in UE5.1 sequencer, render movie also has the correct camera set… and in EU5.1 it is still impossible to render a movie from the correct camera
Also I have experienced tons of issues with the UE5.1 sequencer, like assets not responding (Render Text objects with scale and visibility issues, regular objects scaling in the sequencer but not responing In-game to the sequencer, Niagara not triggering when requested in the sequencer or triggering from start even if not active from start) most issue hapen in-game, other issues happen in the viewport after saving the project and restarting it.
Please fix UE5’s sequencer, it is completly broken, and I am a cinematic artist who works making cinematics for games, of course in UE4, so I know how to work with the sequencer, UE4 sequencer is great, but U know we all want to try UE5.
