Runway adds Enhance Frame Rate; ElevenLabs launches Instant Soundtracks
Runway's Enhance Frame Rate interpolates footage up to 4K and 5 minutes across 24–120fps, also via API, while ElevenLabs auto-generates synced music and sound effects with separate track export.
RUNWAY AND ELEVENLABS JUST AUTOMATED TWO MORE STEPS OF VIDEO PRODUCTION AI-generated video is getting easier to produce, but turning raw footage into a finished marketing creative still requires editing, sound design, and technical adjustments. Two recent releases are starting to automate those steps. @runwayml introduced Enhance Frame Rate, a tool that generates intermediate frames to convert existing footage into smoother video. It supports: 24, 25, 30, 48, 50, 60, and 120 fps 23.98, 29.97, and 59.94 fps delivery formats Existing footage up to 4K Videos up to 5 minutes long The tool preserves the original duration while generating additional frames. It can be used inside Runway workflows or through its API. @ElevenLabs approached the same production problem from the audio side. Its new Instant Soundtracks feature analyzes uploaded footage and automatically generates music with synchronized sound effects. The system can: Identify moments that need sound effects Generate music that follows the video's pacing Synchronize effects with on-screen actions Adapt the soundtrack when the mood changes Export music and sound effects as separate tracks That last feature is particularly useful because editors can still adjust timing, replace sounds, and refine the final mix. Now consider what happens when these capabilities become part of a larger AI production pipeline. A marketing team could generate a video, adjust its frame rate, produce a soundtrack, synchronize effects, and prepare several creative variations with significantly less manual work. These tools don't eliminate editing. Frame interpolation can introduce visual artifacts, while generated audio still needs creative review. But the direction is clear. Video post-production is gradually being broken into smaller operations that specialized AI systems can execute. For marketers, that means the cost of producing and testing creative variations could keep falling. And when execution becomes cheaper, the bottleneck shifts toward developing concepts worth testing, understanding the audience, and identifying which creatives actually drive results. The next advantage in AI video marketing won't necessarily come from generat
