Unicode FM AbhayaFM Abhaya text looks like Latin letters unless the original FM Abhaya font is installed — that is expected. Use the Unicode files for modern players and the FM Abhaya files only in older Sinhala subtitle software.
What you get
Six ready-to-use subtitle files plus a zip, from one upload.
Unicode
SRT · VTT · TXTStandard Sinhala for VLC, YouTube, Premiere, CapCut and any modern player.
FM Abhaya

All six files + READMEOne click, everything bundled with a note on which set to use.
How it works
1Upload your video or audio file — MP4 is the safest bet if you are not sure.
2Hang on a couple of minutes. Each stage lights up as it finishes, so you always know where it is.
3Download your subtitles and drop them straight into your editor, player or upload form.
FAQ
Do I need an account or a technical setup?
No account needed. Purchase a minutes package from the administrator, enter your activation key, then upload a file. Buy the minutes you need; unused credit stays on your key. Payment is confirmed manually before your key is issued.
What happens to my video?
It is used only to produce your captions and is deleted from our server as soon as they are ready. We do not keep a copy, and we do not use your files for anything else.
What files can I upload?
MP4, MOV, MKV, WEBM, AVI and audio-only MP3, WAV, M4A, AAC, OGG — up to 1024 MB per file. Only the sound matters for subtitles.
Unicode or FM Abhaya — which one do I need?
Use Unicode for VLC, YouTube, Premiere, CapCut and subtitle editors. Use FM Abhaya only in older Sinhala subtitle software that expects that encoding.
How long does it take?
Roughly a couple of minutes for a short clip and longer for a long video. Keep this tab open while it works — you will see each stage as it finishes.
Something went wrong with my file
Very long files, silent files and unusual formats can fail. Try a different export (MP4 is safest) or a shorter clip, then try again.
