Have you done any translation videos for your clients? If you are working with Adobe Premiere Pro and If you have like 100 text layers --- you need to change for example the font color for all of them - that's going to be hard (to change the color to the 100 layers) - UNLESS you have applied a MASTER STYLE to your text layers. You can do as many master styles you want and use different font families, color, size etc. for each style. This master style thing comes very handy when you think you need suddenly to change your video's 100 text layers font size or anything else. This little thing saves you lot's of time. —Olohuonetuotanto
