What is CapCut automatic subtitling and how does it work?

CapCut's automatic subtitling feature It uses artificial intelligence to recognize speech in video and convert it into time-segmented text. This way, you don't have to type everything by hand: the tool creates subtitle lines that match the rhythm of the dialogue, speeding up your workflow, especially for long or multi-part pieces.

CapCut is multilingual and recognizes audio in several languages ​​(from English to Japanese, among others), although accuracy depends on the quality of the voiceover and the recording environment. In noisy conditions or with confusing pronunciation, accuracy decreases; therefore, improve audio at source (close mics, noise reduction, clear intonation) is key to fine results.

Good practices: readability, accuracy, timing and position

Readability is keyFour factors make a difference in whether your subtitles are easy to read at a glance: size, color/contrast, background, and font. Fine-tuning these factors will prevent the text from obscuring the content or making it difficult to read.

Subtitle sizeAvoid fonts so large they obscure key elements of the plan, or so small they force your eyes to squint. On mobile devices, it's a good idea to increase the font size by one point because the screen is smaller.

color and contrast- If the video background is light, white text may be lost; add a black outline or shadow to increase visibility. CapCut allows you to add a color or shadow box quickly, which improves reading in highly textured scenes.

Background and location: Using a semi-transparent rectangle behind the text helps in shots with changing backgrounds. As for positioning, the bottom part is usually the most comfortableThe center interferes with the content and is distracting. Keep the placement consistent throughout the piece.

Suitable sourceChoose simple, balanced fonts. For corporate videos, a clean, sans-serif font works best; for informal clips, a handwritten font can work well, as long as do not compromise the reading.

Content accuracy: Subtitles should accurately reflect what is being said. If there are swear words you don't want to include, you can replace them with symbols or paraphrase them, but don't leave any gaps uncovered; subtitles must accompany the entire footage.

Synchronization with speech: The key is to have them come in and out in time with what's happening on screen. CapCut's AI automatically adjusts the timing, but check them in case you need to fine-tune any phrases so that appear exactly with the voice of the speaker.

Visual stabilityAvoid constantly changing position or style throughout the video; constant variations are distracting and worsen the user experience. Maintain consistency in styles, sizes, and placement.
