Compare production responsibilities before vendor names. A tool may generate a scene, a producer turns a brief into an ad, and whoever runs the ads, the brand's team or the production partner, launches and evaluates it. These jobs can sit with different people.
Three ways to organise production
In-house production suits teams with scripting, art direction and editing capacity. Assess whether a tool removes a specific bottleneck, counting training, selection and correction time.
An external specialist may suit product animation or a bounded series of backgrounds. A recurring partnership may suit ongoing output and coordination. Ask what remains your responsibility. A subscription does not automatically supply a complete production function.
Test the everyday handoff
Give candidates the same approved product reference and inspect the route from brief to finished file. Record questions, corrections and missing delivery information. This is more useful than comparing selected showreels.
Use multiple suppliers only if you can coordinate them. Separate image and video tools can work together, but someone must own product consistency throughout. Name that role and check whether another team can take over the work.
