How to add animated captions that stay readable

Prepare a clean speech source

Finish the main cuts and listen for overlapping speakers or music that hides words. Select the spoken clip when it contains the explanation you need; choose the audible timeline mix when the voice spans several clips.

In Auto Captions, select the spoken language or use Auto detect. Leave Translate to English disabled for speech-synchronised word animation. Translation changes word order and uses full phrases rather than assigning the original timestamps to different words.

Compare modes using the same sentence

Try Karaoke highlight for a stable phrase with a moving emphasis. Use Build word by word to reveal the sentence as it is spoken. Pop one word and One word at a time give each word more visual prominence; check whether they leave enough context for a technical explanation.

Words per phrase controls how much text can appear together. Start with a compact phrase and inspect a fast sentence as well as a slow one. A setting that works for a greeting may be too busy for a sentence full of product names.

Animated video captions

Resolve timing and readability problems

Word modes are unavailable

Older caption groups can lack word timing data. Regenerate the captions to obtain speech timings. Switching the animation alone cannot create missing timestamps.

The highlight is hard to see

Choose a contrasting highlight and test it against the brightest part of the footage. A background or shadow can separate text from the picture, but keep the overall caption shape compact.

The words compete with the action

Move the caption group away from the key detail or use Full phrase for that style of explanation. A calm subtitle can be more useful when viewers must inspect a menu or hand movement.
