FrameBeat

The calculation uses the Euclidean algorithm to find the Greatest Common Divisor (GCD) of width and height. Dividing both by the GCD yields the simplest integer ratio.

Social media apps display interface elements (like, comment, share buttons, descriptions, and sound titles) directly over video playback. Keeping captions and faces inside safe zones prevents them from being covered.

Resolution is the total number of physical pixels (e.g. 1920×1080), while aspect ratio is the geometric proportional relationship (16:9). Multiple resolutions can share the same aspect ratio.

When footage filmed at high frame rates (e.g. 70 or 120 fps) is placed onto a 24 fps timeline, dividing 24 by the source FPS gives the exact slow-motion playback percentage without dropping or duplicating frames.

Aligning delay pre-delays and reverb decays to the song's musical tempo (BPM) keeps the mix clean, prevents rhythmic clashes, and creates a cohesive sense of groove and space.
