Recorded loops and real-time rendered scenes: strengths and weaknesses in a shop
There are two broad ways to make what are called "ambient videos" or "healing videos": a recording that is repeated, and a scene that is calculated and drawn on the spot, for example in a browser. Neither is better in general; they are good at different things. Here is a comparison, as fair as we can make it.
Recorded video (looped)
A filmed or recorded video of a few minutes to a few hours is played again and again. Most ambient videos on video sites are of this kind.
- Strengths: nearly any device that can play video can show it, even a USB stick or an old player. Being live footage, it has a photographic texture.
- Weaknesses: a short video repeated makes the return of the same scene obvious, and some videos show their seams. Staff who are there all day may find it monotonous.
- Data: if streamed over the internet, it keeps receiving video data.
- Rights and operation: on a video site you have to deal with ads, suggested videos and the terms (YouTube's Terms).
Real-time rendering
Flames, waves and sunlight through leaves are calculated and drawn on the spot, in the browser. keensense, a service run by the people who wrote this article, is of this kind.
- Strengths: the same moment never comes twice. The shape of the flames or waves differs every time, so repetition is hard to notice. No video is streamed continuously, so data use is low (once the scene is loaded, your own device does the drawing). No ads and no playback bar.
- Weaknesses: drawing needs some graphics power. On old TVs with built-in browsers or very old tablets, motion may not be smooth. It is a computer-drawn picture rather than live footage, so if you want a photographic look, tastes differ.
Five points to consider in a shop
- How long people look at the screen: for a few minutes, a loop is fine. For staff who are there all day or regulars, repetition stands out.
- The equipment you have: recent PCs, iPads and Fire TV Sticks can show real-time scenes. If you only have old equipment, a recording is safer.
- Your connection: if your Wi-Fi is unstable, anything that streams continuously is more likely to stall.
- Rights and ads: if you use a video site, check the terms and ads.
- Taste: do you want the texture of live footage, or a quiet picture? The best way to decide is to see samples on the actual screen.
Each has its place
A shop with old equipment, a wish for a live-footage texture and short viewing times may suit a recording. A place where the screen is visible all day, and where you want to avoid ads and extra handling, may suit real-time rendering. Either way, the most important thing is to choose something that is clearly allowed to be shown in a shop. You can see keensense samples on your own screen; please check that the motion is smooth on your equipment before you decide.
