YouTube is an excellent way of informing others about your products, but it's surprising how many video clips involve the same fundamental errors, everything from interjecting speech with "um," to allowing the camera to lose its focus. Even videos from supposedly professional media outlets can involve a depressing level of amateurism.

The solutions to such sins are often incredibly simple, and just take a few moments to learn and perfect. And if you're going to do something, it's best to do it right... right?

Here are the top six sins frequently found on YouTube videos, along with simple fixes.

1. Erm, quit it with the, um, fillers

Once upon a time littering conversations with fillers, words like "um" that provide conversational space while your brain sorts itself out, was enough to invoke corporal punishment from teachers. This was an effective way of training individuals to avoid them but times change. In everyday speech fillers are common but usually ignored. On a web video or podcast they can become intensely annoying, perhaps because microphones are unforgiving and seem to pick them out.

The solution is twofold. First, make a bullet point list of all the points you want to make during the video and stick it just below the camera so you can see it at all times. Second, rehearse a few times before going for a take, go through the motions of what you intend to say without actually hitting the Record button.

This is how professional speechmakers sound so fluent. Of course, if you can prepare a full script and learn the words then that's even better, but don't punish yourself if you find yourself deviating from the page during the recording, nobody but you will know. Allow yourself to be flexible.

2. Hold the camera steady

Almost everybody suffers from motion sickness to some degree. Wobbly camera work in a video or zooming in and out can trigger it very effectively and quite literally make a video presentation unwatchable. My particular hate is when the camera's autofocus fails and everything goes blurry. That's enough to make my eyes water.

Get a tripod and fix your camera to it. All modern cameras have a tripod mount at the bottom, that's the little round hole near the battery compartment, and it's a universal fitting, so all tripods will be OK.

Secondly, before hitting the Record button, make use of autofocus fix, if your camera has one (check the manual if you're unsure). This will stop the autofocus hunting if the light changes, for example.

Thirdly, never zoom the camera during shooting. If you need close-up detail, shoot it afterwards using macro mode and cut it into the video during editing (you only need to insert the visuals, of course, not the audio).
