Twitter/X Video: Capturing Attention with Captions
Twitter/X is a fast-scrolling platform where you have mere seconds to capture attention. Videos autoplay silently, making subtitles essential for stopping the scroll. Without captions, your video is just moving images that most users will scroll past.
Engagement on Twitter/X directly influences visibility. Subtitled videos receive more replies, retweets, and likes because viewers can actually understand the content. This engagement signals quality to the algorithm, amplifying your reach.
With Twitter/X character limits on text posts, video lets you communicate more complex ideas. Subtitles ensure your message comes across clearly, even in a distracting, fast-paced feed environment.
Pro Tips
Front-Load Your Message
Twitter users decide in 2-3 seconds whether to watch. Put your most compelling content and captions first.
Keep Videos Under 45 Seconds
Short, punchy videos perform best on Twitter/X. Make every second and every caption count.
Use Large Text
Twitter videos appear small in the timeline. Large, bold captions ensure readability before users tap to expand.
Match Platform Tone
Twitter/X is conversational. Use casual, direct language in your captions that matches the platform's voice.
