Generate Bulgarian subtitles for your Serbian videos

From Cyrillic and Latin to Cyrillic

Serbian is written in Cyrillic and Latin, both in everyday use and Bulgarian in Cyrillic, 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 Bulgarian 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.

How Serbian audio becomes Bulgarian subtitles

Audio in Serbian (Српски / Srpski) is transcribed first, then translated into Bulgarian (Български). Because the translation runs on the transcript rather than on the audio, the Bulgarian subtitle file keeps the timings of the original Serbian speech — each line appears at the moment it was actually said.

Why translate Serbian video into Bulgarian

Serbian is spoken principally in Serbia, Bosnia and Herzegovina, and Montenegro; Bulgarian in Bulgaria. A Bulgarian 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 Serbian audio

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.

About the Bulgarian subtitles

Bulgarian is unusual among Slavic languages in having dropped noun cases and in attaching its definite article to the end of the word rather than placing it before. It is also close to Macedonian, close enough that detection between the two is not dependable.

What a Serbian to Bulgarian subtitle file looks like

Four lines of Serbian speech, transcribed and translated, as they come out of the exported SRT. The timings are the Serbian 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 Serbian may need loosening to read well in Bulgarian.
• That Cyrillic renders in your player, not just in the editor you exported from.
• Timing on fast exchanges, where two speakers overlap.
