Yeah. From the first glance I see a lot of missing details being glossed over. Like what encoder is being used? Output format "mp4" is a container format, so is webm. Knowing the codec is important to decide whether the file is appropriate for where I want to play it. What if my TV doesn't have HEVC support and you are using it inadvertently? Also, what does each quality setting mean? Or the tradeoff between CPU usage and efficiency? Asking ChatGPT to come up with an ffmpeg command has none of these problems as all the details are exposed to you.
