Preguntas Frecuentes
Can I add text only to part of the video?
Not in this tool — the text shows for the full duration. For time-ranged captions author an SRT in any plain-text editor and burn it in with the Subtitle Burner tool.
Does it support emoji and non-Latin characters?
Partial — FFmpeg drawtext uses the embedded default font which covers Latin/Cyrillic/Greek. Chinese/Japanese/Korean/Arabic and emoji are unlikely to render. For those, use the Subtitle Burner with an ASS file specifying a font that supports your script.
Is it the same as a watermark?
Functionally similar (persistent overlay) but the Watermark tool is optimised for logos and corner placement. Use this tool for text-focused overlays (titles, call-to-action, disclaimers).
Will the quality change?
Video is re-encoded at CRF 23 (visually lossless). Audio is stream-copied — untouched.
