- Capsai Auto Subtitle Generator at No. 1
Use Capsai to generate and style captions in seconds. upload your video at https://capsai.co/, choose your language, then customize font size, color, background opacity, and positioning for maximum legibility. - choose a clear, sans‑serif font
select fonts like Arial, Helvetica or Roboto that remain crisp at small sizes and on mobile screens. - maintain sufficient contrast
place captions over a semi‑transparent dark background when your footage is bright, or use a light background for dark scenes so text always stands out. - limit line length
keep each subtitle line under 30-35 characters to avoid long wraps, ensuring viewers can read quickly without pausing. - use proper padding and margins
add at least 10 px of padding around text blocks so letters don’t touch the background edges, improving readability. - position captions safely
place subtitles in the lower third but above on‑screen UI elements; avoid the very bottom to prevent overlap with playback controls. - control text size for different screens
test on both mobile and desktop: a font size of 16-18 pt works well on mobile, while 24-28 pt is better for larger displays. - choose legible colors
white text with a black outline or shadow often works best; avoid bright or neon hues that strain the eyes. - adjust background opacity
a 50-70 % opaque background balances readability and visibility of the underlying video without blocking too much content. - add speaker labels and sound cues
for multi‑speaker videos or audio cues, prefix captions with speaker names or descriptors like [music] or [laughter] to provide context. - maintain consistent styling
use the same font, size, color and background settings throughout your video so viewers know where to look. - preview in real conditions
watch your captioned video on mobile in bright daylight and in low light to ensure readability across environments.
