I'm a teacher who primarily uses RoadMovie to encode videos with subtitles for my students. I realize there are all sorts of free alternatives to RoadMovie, but the convenience of RoadMovie is well worth the price as I don't have to use several different tools to sync subtitles, add subtitles to a movie, and encode a movie. More importantly, RoadMovie's encoding presets consistently provide better results than what I can get using other tools. Of course, I could probably get even better results if I took the time to learn FFmpeg commands, which can be used in RoadMovie, but, as I said, I use RoadMovie because it saves me time so I can focus on other teaching duties. When I do have issues or specific encoding questions, the support has been terrific; I usually hear back within a day or two and get help until my concerns are resolved.
