Fix broken Hindi captions: text, font or layout?
A diagnostic sequence for misplaced vowel marks, unexpected glyphs and clipped Devanagari in exported video.

When Hindi captions look wrong, check the transcript first, then font coverage, shaping and the space around the line. The visible symptom alone does not identify the cause.
A practical editing guide from the LumaCaption team. The examples below are checks you can repeat on your own footage; they are not claims from a comparative product benchmark.
Separate a spelling error from a drawing error
Copy the suspect word from the transcript into another application with a Devanagari-capable font. If the spelling is wrong there too, correct the text. If it looks right elsewhere, investigate the font or rendering path in the caption tool.
Do not repair a vowel mark by inserting spaces inside a word. That can change shaping and make an apparent layout fix into a text error.
What the symptoms can mean
Use these as diagnostic leads, not definitive diagnoses.
Five checks for the exported frame
| Symptom | Possible causes | Next check |
|---|---|---|
| Unexpected boxes or replacement glyphs | Missing font coverage or unavailable font | Try another Devanagari-capable font |
| A dotted circle beside a mark | A detached mark, invalid sequence or shaping issue | Inspect the underlying text before changing fonts |
| Unexpected conjunct or visible halant | Spelling, joiner characters, font design or shaping | Compare the intended word in a known-good font |
| Marks cut off above or below | Insufficient line height or clipping | Increase available space and inspect the export |
| Hindi and English weights look mismatched | Fallback font or different weight availability | Compare both scripts in the final style |
Keep the parts of a syllable together
Devanagari combines consonants and vowel signs into shaped units. Character spacing or line breaks inside these units can disrupt the result. W3C’s Devanagari guidance treats orthographic syllables as important units for text operations.
A visible virama does not by itself prove a broken renderer. Correct text can have different appearances depending on the chosen sequence and font. Confirm the intended spelling before diagnosing a missing ligature.
A useful sample to export
Try विज्ञान, श्रृंखला, कृपया and ज़रूरी beside a real name from your video. Use the caption style and size you plan to publish. The sample exercises several combinations; it does not exhaust the script.
In LumaCaption, selected caption families use Devanagari companion fonts. Review the companion’s appearance in the preview and the exported file instead of assuming a Latin font’s personality transfers exactly.
Finish with a reading pass
Ask a fluent Hindi reader to check the full caption sequence where possible. A typographically tidy frame can still contain the wrong word.
For mixed Hindi-English speech, choose the intended script before editing: Devanagari Hindi and Roman-script Hinglish are different presentation choices.
