How to make key words bigger inside your captions
Ask Vizard Agent for captions with emphasised key words and say what should be emphasised. The styling is the easy half. The half that matters is that the captions are built from word-level timings, so the bigger word appears exactly as it is said rather than a beat late.
What do you type into Vizard Agent?
Say both parts of it: the look and the rule behind it. "Some key words larger and in a different colour" describes the look you want, while "the emotional ones" or "the numbers" is the rule Vizard Agent will apply when it decides which words get the treatment.
Prompt
What does Vizard Agent actually do?
The word timings come first because every later decision depends on them. Line-level captions can be styled but not emphasised: a bigger word inside a line that appears all at once has no moment to land on. The placement is fixed last, once the emphasis exists. The job was a music-led vertical video. In the session behind this article it:
- Checked the video's duration and format and the caption tools available, and made a visual sample to review the composition and the safe caption area.
- Transcribed the audio with word timings and inspected the word-level timing file so the animation could be precise.
- Generated a vertical caption base with timed word reveals, then regenerated it using only the supported styling controls when the first attempt exceeded them.
- Applied larger, accent-coloured emphasis to the chosen keywords, rendered and reviewed the captions across the edit, and measured the audio level.
- Lowered the caption block so the taller emphasised words cleared the main action, re-rendered, and confirmed the captions stayed legible and in sync.
When does this not work well?
Some material resists emphasis altogether. Fast speech leaves no room for a bigger word to register, dense captions become a mess of competing sizes, and a video in which Vizard Agent emphasises every word is a video with no emphasis in it at all. Busy backgrounds swallow the accent colour, and poor audio spoils the word timings.
Common questions
Can it pick the words itself? Yes. Give Vizard Agent a rule, such as emotional words, numbers or names, and it applies it.
Can I list the words instead? Yes, and Vizard Agent emphasises exactly those and nothing else.
How many words should be emphasised? One or two per line. More than that and Vizard Agent will tell you it stops reading.
