The Video Profiler module displays information about what resources the video in your application is using, such as memory, buffering, and number of video clips. You can use this data to determine how efficiently your application plays back and buffers videos on your selected platforms. You can also use the CPU Usage Profiler module to assess where Unity spends time on video. For more information, refer to CPU Usage Profiler module reference.
