You can override any preset's setting, such as a file's bitrate, or even the file's format & codecs via a Robot's ffmpeg parameter.

The hls- and dash- presets are intended for use in combination with 🤖/video/adaptive.

These are supported if you were to specify ffmpeg_stack: "v5.0.0" in your Assembly Instructions. The recommended version is: v4.3.1
