Length and layout
English is about 10–15% shorter than the Indonesian original. Both languages are written left to right, so the layout does not change — only the wording and line length do.

Getting English right
English subtitles read fastest when a line breaks after a clause, not mid-phrase — the editor lets you move the break without touching the timing.
Workflow
From Indonesian to English in three steps.
Upload the Indonesian video
Add a video or audio file. SubFlow transcribes the Indonesian speech into timed captions.
Translate into English
Pick English 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 English or bilingual subtitles, a subtitled video, or a English dub.
Common questions
Indonesian to English, answered.
Can SubFlow recognise Indonesian speech automatically?
Yes. Leave the source on automatic detection or pick Indonesian yourself. Indonesian speech often mixes in English terms; those stay in English in the transcript, which is usually what viewers expect.
Will the English subtitles fit on screen?
English reads comfortably at 15–17 characters per second with about 42 characters per line. English is about 10–15% shorter than the Indonesian original. Review the longest captions and split any that crowd two lines.
Can I dub a Indonesian video into English?
Yes, on the Pro plan. The English dub uses a en-US voice and is spoken from the translated subtitles, so correcting a line in the editor changes what the voice says.
Can I export Indonesian and English together?
Yes. Export the English subtitles alone, the original Indonesian, or a bilingual SRT with both on each caption — or burn either into the video.
