Auto-Subtitling & Translation

Subtitles, dubbing, or both

These are different products with different costs and different appropriate uses.

Why dubbing beats subtitles for some audiences

Subtitles assume the viewer reads comfortably and quickly in the subtitle language. For a large part of the Indian workforce, particularly in manufacturing, logistics and field roles, that assumption does not hold.

A safety training video with Hindi subtitles reaches fewer workers than the same video dubbed into Hindi. This is not a marginal difference and it is the single most common reason our clients choose dubbing for internal content.

For marketing and social content the calculation is different — subtitles are cheaper, work when muted, and audiences are used to them. We usually recommend captions everywhere and dubbing selectively where comprehension genuinely matters.

Timing, which is what makes subtitles readable

Correct text with bad timing is unreadable. Subtitles need to appear with the speech, stay long enough to read, break at sensible points in the sentence, and not exceed two lines.

Translation complicates this because languages expand and contract. Hindi text is often longer than the English it came from, and a literal translation frequently will not fit in the time available. The pipeline shortens where necessary while preserving meaning, which is a judgement the system makes and a reviewer checks.

For dubbing the same problem is harder, since the audio has to fit the visual timing. We adjust pacing and phrasing rather than speeding up the voice, which is what makes some dubbed content sound rushed and unnatural.

Running it across an existing library

The usual engagement is a back catalogue — sixty hours of training video, or three years of marketing content.

The process is a pilot on five representative videos to calibrate the glossary and check quality per language, then the bulk run, then a review pass focused on flagged segments where transcription confidence was low or translation was uncertain.

Review effort is roughly ten to twenty per cent of what full manual work would cost, concentrated on the parts that need it. For a sixty-hour library, that is a manageable piece of work rather than a project nobody starts.

Cost, formats and handover

Three to six weeks from ₹1,50,000 for a typical library project, with cost scaling by hours of video and number of target languages rather than by video count.

Output comes as SRT and VTT subtitle files, burned-in versions where you need them, and dubbed audio tracks or complete rendered videos. YouTube, Vimeo and most learning platforms accept the subtitle files directly.

You get the pipeline for ongoing use, the glossary, and full source, so new videos get captioned and translated as they are produced rather than accumulating into another back catalogue.
