There is no definitive answer to this question, as it depends on your objectives, audience, message, and budget. However, some general guidelines would be: Use photos when you want to show the subtle details, features, or facilities one gains by consuming your products or services. Use videos when you want to tell a story, elaborate a process, or demonstrate the process how something works. Use a combination of both when you want to foster a comprehensive and immersive experience for your viewers.
