PC Resource Consumption 1. PC Resource Consumption: Video conversion is a resource-intensive task, especially for CPU and RAM. An older PC or one with little RAM may experience significant slowdowns during the process. This can be noticeable for large MP4 files. 2. FFmpeg Requires Technical Knowledge: Using FFmpeg via the command line or a PowerShell script requires some learning and familiarity with the commands. For example, you must install FFmpeg on your machine. 3. FFmpeg Is Less Intuitive: No user-friendly graphical interface (unless you develop a user interface for your script).
