TikTok is now a leading force in digital content consumption largely due to its unique approach to video content and the variety of formats it supports.

Videos should be no longer than 10 minutes, although most viral content falls within the 15 to 60 second range. Shorter videos typically perform better due to TikTok’s algorithm favoring quick, engaging clips that keep users scrolling.

TikTok accepts multiple video file types, including MP4 and MOV, which are the most commonly used and reliable options. Use H.264 for video and AAC for audio to ensure compatibility to ensure smooth playback across all devices. Avoid using outdated or less common codecs as they may lead to upload failures or poor video quality.
