[HELP] What are the prerequisites for Level 4.2?

[chris]

I noted Hybrid said it was preferring the container frame rate,

You can change that under: "Config->Internals->Prefer Original" (Original = stream info)

I did notice that; I'm currently running an encode using Filtering -> Speed Change -> Change speed: 50 fps selected, though will that alter audio?

I couldn't figure out a way of easily encoding a small segment through the GUI (like -ss 00:03:00 -t 00:00:30), forgive my ignorance.
