Turn Bosnian video or audio into Serbian subtitles, exported as SRT, VTT or plain text with the original timings intact. Bosnian and Serbian are close relatives, so set both languages explicitly rather than relying on detection.
Choosing between Bosnian and Serbian
Bosnian and Serbian are close enough that automatic detection between them is unreliable, especially on short clips — there is simply not enough audio to tell them apart. Set both languages explicitly here rather than leaving the source on detection.
Because the two are so close, translation between them is largely a matter of vocabulary and written convention rather than restructuring sentences. Expect a Serbian subtitle file that tracks the Bosnian original almost line for line.
How Bosnian audio becomes Serbian subtitles
Audio in Bosnian (Bosanski) is transcribed first, then translated into Serbian (Српски / Srpski). Because the translation runs on the transcript rather than on the audio, the Serbian subtitle file keeps the timings of the original Bosnian speech — each line appears at the moment it was actually said.
From the Latin alphabet to Cyrillic and Latin
Bosnian is written in the Latin alphabet and Serbian in Cyrillic and Latin, both in everyday use, so the exported file uses a different writing system from the audio that produced it. The subtitle formats handle that — SRT and VTT are plain text and carry any script — but the font in whatever plays the file has to cover it.
This is the most common reason a Serbian subtitle track looks correct in an editor and shows boxes or blanks on a device. Test on the target platform before you publish a batch.
Why translate Bosnian video into Serbian
Bosnian is spoken principally in Bosnia and Herzegovina; Serbian in Serbia, Bosnia and Herzegovina, and Montenegro. A Serbian subtitle track is what lets one recording reach both audiences without re-recording, re-editing or dubbing it.
Because subtitles are a separate file rather than part of the picture, you can attach several language tracks to the same video and let viewers pick.
About the Bosnian audio
Bosnian, Croatian and Serbian are close to identical in speech, and the choice between them is mostly about which written conventions and vocabulary you want rather than what the recording sounds like. Bosnian uses the Latin alphabet and admits more Turkish-derived vocabulary than its neighbours.
About the Serbian subtitles
Serbian is written in both Cyrillic and Latin, and the two are used interchangeably in practice. Serbian, Croatian and Bosnian are close enough in speech that the choice between them is largely about which written conventions you want.
What a Bosnian to Serbian subtitle file looks like
Four lines of Bosnian speech, transcribed and translated, as they come out of the exported SRT. The timings are the Bosnian speaker's — translation does not move them, which is why the file drops onto the original video unchanged.

What to check before publishing
Names and places, which translation handles less reliably than ordinary prose.
Idiom — a phrase that is natural in Bosnian may need loosening to read well in Serbian.
That Cyrillic and Latin, both in everyday use renders in your player, not just in the editor you exported from.
Timing on fast exchanges, where two speakers overlap.
Transcribe
Transcribe Your Video/Audio to Subtitles Automatically.
It can, if you leave the source on automatic detection — the two are close enough that a short clip does not give detection much to work with. Setting Bosnian explicitly removes the guess, and is worth doing on anything under a minute.
Will Serbian display correctly in my player?
Almost always, but it depends on the font rather than the file — SRT and VTT are plain text and carry Cyrillic and Latin, both in everyday use without difficulty. If you see empty boxes, the player is missing a font for the script, not reading the subtitles wrongly.
How do I add Serbian subtitles to a Bosnian video?
Upload the video, set the spoken language to Bosnian and the subtitle language to Serbian, then export the result as SRT and upload it alongside your video. Nothing is burned into the picture, so the subtitles stay switchable.
Does the Serbian subtitle file stay in sync?
Yes. Translation happens on the transcript, so every Serbian line inherits the timing of the Bosnian words it came from. The file will sync with the same video without adjustment.
