What bilingual subtitles are
Bilingual subtitles show two languages at the same moment — usually the language spoken in the video and a translation of it. SubtitlePop writes the first from the audio and the second with the built-in subtitle translator, and keeps both on the same timing.
Translating uses about half of the video’s speaking time from your minutes for each language, so a 10-minute video takes about 5 minutes. The original captions are charged once, like any other video.
How to make bilingual subtitles
Upload the video
The speech becomes captions in the language spoken in the video.
Translate the captions
Open Translate in the editor’s top bar, pick the second language and select Translate captions.
Keep “Both languages” and export
The preview shows the original with the translation beneath it. Export an MP4 with both burned in, or a subtitle file with two lines per caption.
How bilingual subtitles look on the video
The original caption keeps the style you chose — including word-by-word highlight — and the translation sits directly under it in a smaller size, in white with the same outline. When a caption is placed low on the frame, both lines move up together so nothing is cut off.
The preview in the editor is drawn by the same renderer that writes the exported MP4, so the two languages appear in the file exactly where you saw them.
Bilingual subtitle files: SRT and VTT with two lines
With “Both languages” selected, each caption in the exported SRT or VTT file has the original on the first line and the translation on the second, under one shared time range:

00:00:00,750 --> 00:00:02,670

Who uses dual-language subtitles
- Language teachers and learners — the spoken language and the viewer’s language on screen together.
- Creators with a mixed audience — one upload that reads for two groups of viewers.
- Teams and events — talks, training and announcements for people who share a room but not a first language.
