FAQ
Can I use this as an auto caption generator?
Yes. Upload a video with speech, pick a caption style, and render a captioned MP4.
Where should I put captions on Instagram Reels?
Place captions in the safe middle area (between 20% and 80% screen height) to avoid being covered by Instagram's bottom engagement buttons or top account handles.
Are captions burned into the final video?
Yes. Captions are rendered into the MP4 so they show on Instagram, YouTube Shorts, TikTok, and other platforms.
How do I add subtitles to Instagram video automatically?
Upload your video to Itnavideo's Auto Caption Generator. Speech AI detects spoken timing and burns word-level animated subtitles into your MP4 in seconds.
Does Itnavideo support Hinglish captions?
The current caption flow supports English and Roman Hinglish output from the supported transcription pipeline.
