When we started it was just Remotion, but yes tons of other options have exploded onto the scene. Long-term we want to be as zen as possible, where Opus 5.5 and its successors make graphics and edit videos in whatever form hobbles them the least. So far, Remotion has allowed us to achieve WYSIWYG editing while also handling very complex timelines with heavy duty media formats

OP can add their answer but I'm also in the same boat (building chatoctopus.com) and would say Remotion is well-established as a video framework and also has a lot better support for infra/rendering. Rendering takes a lot of time and Remotion's Lambda fanout is amazing for speed up.

Others feel vibe-coded (looking at you hyperframes), and LLMs have to learn their syntax from scratch. X influencer forget to tell you how slow your output would be.
