Add Text to Video

Yes. Specify start and end timestamps in your prompt (e.g. 'from 0:05 to 0:20') and the agent will attempt to match that timing. Very precise sub-second timing may vary slightly depending on the video's frame rate and encoding.

Most of the time, yes. Describe each text overlay with its own timing and position in a single prompt and the agent will try to apply all of them. Highly complex multi-layer requests may produce better results if broken into steps.

You can request general styles like bold, italic, serif, sans-serif, handwritten, or neon, and specify any color. The agent selects the closest available match — exact proprietary font names are not guaranteed.

It depends on the video. Requesting a text shadow, outline, or background box in your prompt (e.g. 'white text with a dark semi-transparent box behind it') usually makes captions readable regardless of background color.

Yes — you can supply translated subtitle text yourself and specify the timing, and the agent will render it onto the video. Automatic translation is not included; you would need to provide the translated lines.

Common formats like MP4 and MOV typically work well. Shorter clips (under 5 minutes) tend to process faster and more reliably. Very long videos or unusual codecs may produce slower results or require re-encoding first.

Yes — adding text to a video runs on your Happycapy plan's credits rather than a free tier. Longer or higher-resolution clips use more of your plan's usage limits.
