Multimodal video analysis
Also known as: multimodal AI, audio-visual analysis, video understanding
AI analysis that reads video frames, sound and sometimes text together, so a model understands what happens in footage rather than only how it looks.

What it means
A modality is a type of input: images, audio, speech, text. Multimodal video analysis means a single model takes several of these at once and reasons over them together. Instead of one tool spotting motion and another detecting loud noises, the model sees the rider launch off a kicker and hears the friends shouting in the same pass.
That combined view is what lets modern AI editors describe a scene in plain language, find a specific moment on request, or judge whether a stretch is exciting or merely noisy. It is the step beyond older pipelines that ran separate detectors and glued their outputs together.
How it works in practice
Large multimodal models do not watch every frame. Google's Gemini models, for example, accept video directly and by default sample around one frame per second, alongside the audio track. Each sampled frame becomes a block of tokens, so an hour of footage turns into a very large input, and long shoots are usually split into chunks.
Developers often add their own signals on top, such as motion measurements or scene boundaries, then ask the model to rate or describe each segment. The output feeds highlight detection and decides what goes into the final highlight.
What to watch out for
Sparse sampling can miss fast action. A trick that lasts half a second at a high frame rate may fall between two sampled frames, so serious systems sample denser around motion peaks or pre-filter with cheaper detectors.
Audio can mislead as easily as it helps. Wind noise, rain drumming on the lens, music playing in the car or a waterproof housing that muffles everything all change what the model hears. Models can also be confidently wrong about exact timestamps, so a good pipeline checks the cut points against the actual frames before rendering.
How RawClip handles it
RawClip uses AI analysis of your footage to find motion, jumps, faces and peak action, then removes dull and duplicate parts and cuts the result to the beat of the music. Uploaded raw footage is removed as soon as the highlight is rendered, and none of it ever feeds model training.
