When you think about the creation of closed captions, you might think about the process of noting down the words that need to be written and this is definitely an important aspect of this whole thing. However, you should also try and realize that closed captions are a very visual affair, which means that they need to be able to stand out with so much happening behind them. The backdrop that a closed caption would be displayed over is most likely going to be quite active and distracting, so setting the closed caption apart is an art unto itself, one that you cannot overestimate the importance of.
There are a few tricks that you can use in this regard, and you can click here to learn a little more about them. For starters, you can add a bit of an outline to the closed caption. This can be tricky though because of the fact that you wouldn’t want this outline to be too prominent since this would look bad. You don’t want it to be too fine either since that would defeat the whole purpose of having the outline there in the purpose. Finding the happy medium is crucial here due to the reason that you would want the result to be perfect, so find an outline that just distinguishes the caption from what it is being displayed over.
Another trick is to position the caption properly. Sometimes the focus of a scene is going to be on the top of the frame so having the closed captions at the bottom can be a bad idea. Putting them where you think the action is going to be can help contribute to a much smoother experience.
