Here's an example, and this is a very critically acclaimed safety video. And, yes, I like it as a video, I just don't like it as a way to demonstrate safety.

It takes over 30 seconds before any visual instruction starts.

The business class shoulder harness isn't shown at all and is instead a tiny icon with a moving background shot taking up most of the screen.

The overhead bin animation is not taking place inside a real plane, is barely an outline of a part of a plane, and has most of the image being of a historic building in the background.

The instructions are then interrupted by dancing on the beach for about 10 seconds.

The next instructions has a set of dancers and a very colorful Kathakali dancer taking up most of the screen while the electronic devices are a tiny icon.

No smoking is again a small icon on the side of the screen with the foreground being a much more interesting and compelling visual.

Another 10 seconds of dancing...the video is interrupted constantly and made unnecessarily long.

Emergency exit doors shown as an outline again in a colorful historic building with a dancer moving around as the focal point.

Then the exit aisles are shown not in a plane but as part of an old building.

Oxygen masks aren't shown connected to the plane so it's hard to say where they're coming from.

More dance interruptions with no instructions.

The life vest is probably the first thing that's just as clear as seeing the in-person demonstration.

Then the last 30 seconds is all timewasters.

Again, great video, but it's a brand and tourism advertisement and not a safety video.
