If you want to pick up video editing as a skill, be prepared for a bit of a learning curve. Editing videos requires experience, and the only way for you to get that experience is to dive in and start to try it out.
The first few times that you edit your video you may not even know where to start, what tools to use, or how to go about it. That is why a good way to start learning is with some of the easier tools that are in most video editors:
Split and trim
Trimming out unwanted parts of a video is one of the most basic yet important tasks in video editing – so it is a good place to start. Depending on your editor you may need to use the split tool to isolate the part you want to remove and then delete it, or the trim tool to select the part you want to keep so that everything else will be removed.
If you want you can start to combine videos and experiment with different types of cuts.
The crop tool will delete a segment of the video frame, effectively re-framing the video. It can be used to alter the aspect ratio, and can also help you to improve the composition of your videos with the help of techniques such as the rule of thirds as a guide.
Depending on your editor the crop tool may have a grid that you can use to position elements – or you may have to enable it separately.
Most light sources have a certain colour ‘temperature’ that can cause your video to have a less-than-natural cast of orange or blue. In editors there is normally an automated white balance tool that can help to fix that, and make your video look more natural.
Further improvements can be made by manually adjusting the colour parameters, such as the hue, saturation, and temperature.
Another common problem in videos is footage that looks shaky because the camera wasn’t kept steady while it was recording. In your editor you should have an automated image stabilisation tool that can be used to fix that.
In some cases there may be a ‘tolerance’ or ‘strength’ slider that you can adjust based on how shaky the video is, and how much the editor will need to compensate.
While these tools are generally easy to use, the editor will have a big part to play in exactly how intuitive they are. For example if you use Movavi Video Editor splitting videos will be easy based on the steps at https://www.movavi.com/support/how-to/how-to-split-videos.html.
At the end of the day the tools listed above are a good place to start as they’ll let you fix common issues, cut videos together, and improve how they look. As you become more familiar with your video editor you can experiment with its other features and try them out as well.
