Length and layout
Indonesian is about 10–20% longer than the English original. Both languages are written left to right, so the layout does not change — only the wording and line length do.

Translate English video into Indonesian subtitles
Upload a video in English. SubFlow transcribes the speech, translates every caption into Indonesian, and keeps both languages on the same timeline so you can review them side by side — then export subtitles, a subtitled video, or a Indonesian dub.

Getting Indonesian right
Indonesian captions read naturally in a neutral register; very formal phrasing can feel stiff for social video, and the editor makes it quick to loosen a line.
Workflow
From English to Indonesian in three steps.
Upload the English video
Add a video or audio file. SubFlow transcribes the English speech into timed captions.
Translate into Indonesian
Pick Indonesian as the target. Every caption is translated with the surrounding lines as context, then shown beside the original.
Review and export
Fix names and terms, split any caption that runs long, then export Indonesian or bilingual subtitles, a subtitled video, or a Indonesian dub.
Common questions
English to Indonesian, answered.
Can SubFlow recognise English speech automatically?
Yes. Leave the source on automatic detection or pick English yourself. Accents, fast speech and overlapping speakers are handled well by the Whisper model; background music is the most common cause of a dropped line.
Will the Indonesian subtitles fit on screen?
Indonesian reads comfortably at 15–17 characters per second with about 42 characters per line. Indonesian is about 10–20% longer than the English original. Review the longest captions and split any that crowd two lines.
Can I dub a English video into Indonesian?
Yes, on the Pro plan. The Indonesian dub uses a id-ID voice and is spoken from the translated subtitles, so correcting a line in the editor changes what the voice says.
Can I export English and Indonesian together?
Yes. Export the Indonesian subtitles alone, the original English, or a bilingual SRT with both on each caption — or burn either into the video.
