About TikTok Video Format
Why 9:16 vertical? TikTok is designed for mobile viewing in portrait orientation. Vertical videos fill the entire screen, maximizing engagement and immersion.
Optimal duration: While TikTok supports up to 10 minutes, videos under 60 seconds perform best. The algorithm favors content with high watch-through rates.
Quality settings: Our tool uses TikTok's recommended encoding: H.264 codec with CRF 22 for excellent quality, AAC audio for wide compatibility, and 30 FPS for smooth playback.
