Choose the subtitle source
Open one video, then import SRT or ASS, generate subtitle cues from the video's speech, or write the cues manually one by one.
Burn In Subtitles · ClipFlow Pro
Translate subtitles, then burn the words into your video.
Import SRT or ASS subtitles, generate a draft from speech, or write cues one by one. Edit the cues, optionally translate them into one of seven languages, choose original, bilingual, or translated display, and render the final text directly into a new video.
Captions become part of every frame
How to add always-visible subtitles to video on iPhone.
Burned-in captions do not rely on a player supporting a separate subtitle track, which makes them useful for social posts and silent viewing.
Edit, translate, and style
Review and edit each timed cue. If you want a translation, choose Simplified Chinese, English, Japanese, Korean, Spanish, French, or German. Streamed translations appear below their source cues, and completed languages remain available in the current workspace. Choose Original, Bilingual, or Translation, then style the captions and adjust the translation text size separately.
Burn in and export
Render the selected original, bilingual, or translated cues into the picture and create a video that can be saved, shared, or continued into another compatible tool.
Imported, generated, or manually written cues
An existing SRT or ASS file gives you control over text and timing before import. Automatic generation is faster when the source has clear speech, but names, punctuation, noise, and specialist terms can still need correction. Manual writing is useful when you want to enter every line yourself: add cues one by one and set each start and end time without going past the video's total duration. Every source becomes editable cue rows before rendering.
Burn In Subtitles requires ClipFlow Pro. Final rendering, manual entry, and speech recognition stay on your device. AI translation is an optional online action: when you choose it, ClipFlow sends only the subtitle text to ClipFlow's service and Xiaomi MiMo. The video, audio, timecodes, and subtitle styling are not included in the translation request. ClipFlow does not use your content to train its own models or for advertising. Each Apple purchasing account can request up to 20 subtitle translations per Beijing day across its devices.
