Text to speech voiceovers for video and courses
Murf turns a script into a voiceover in a couple of hundred voices, with per-word emphasis and pacing controls that stop the read sounding flat. The editor syncs the audio against a video track, which is what makes it usable for course modules rather than just clips. Voice generation is metered in hours per year, so a weekly show eats a plan faster than the monthly price implies.

Generative video with an editor around it
Runway is where the frontier video models arrive with a timeline attached, so a generated shot can be trimmed, upscaled and cut against footage you filmed. Credits are the unit of everything, and they go faster than the plan names suggest. Read the credit cost per second before picking a tier, because the gap between plans is nothing like the gap between prices.
Our note
Work out how many seconds of your chosen model each plan buys before subscribing, because the answer is usually smaller than the credit numbers suggest. Runway is the right pick when the shot cannot be filmed. For talking-head video from a script, Synthesia and HeyGen cost less and do it better.
