As steady as you think your hands may be - there will always be movement. This can be distracting when you're watching a video that you know shouldn’t be moving. (as opposed to our L&O style dramas - my favorite) Also the iPhone will work to stabilize the picture regardless and this has an effect on the quality of the video. Also if you're doing multiple takes I can tell you editing will be a lot harder.
To capture good steady video you need to use a tripod. Of course there are times when using a tripod is too restrictive but that's not what we're talking about today. This purchase doesn't have to be a big expense since the prices vary greatly. As well as the sizes. You have to give good thought to what type of tripod will work for your content. Are you doing vlogs? Are you doing a how-to series? Or interviews?
For the simplest of video shoots such as a vlog that you are shooting from your office you could use the basic tripod that was designed for smartphones.
Once you start venturing out into 'how-to' videos - interview style videos you need more height and sturdiness. That's when the more traditional tripods are best. It's important to note here - when you use traditional style tripods you are going to need to buy an accessory - a Tripod Adapter for your phone. (low $) All these adapters have the same component. They have a Tripod socket. Which is - exactly as it sounds. They have a socket that will screw onto your tripod stand. Your iPhone will fit into this accessory and so it can attach to the tripod. Below are some popular Tripod adapters.
And then you can enter the world of iPhone cases. Which I'm going to hold off from going on - I think you got the idea.
As far as tripods go the prices range from super cheap to top tier. You have to get one that fits your budget and feels good and easy for you to set up and take down. One thing to take into consideration before buying a tripod is - where are you planning to shoot? A lightweight stand might not work so well on the carpet or outside on the grass. Since you don't want to worry about your camera taking a dive.
Have any experiences with using a tripod to share? Would love to hear them.
