Captioning & subtitling

Multilingual Subtitle Translation

A good subtitle is a translation and a timing decision at once: it has to fit the shot, sit inside a comfortable reading speed and still read like natural language. I subtitle into native Vietnamese and across English, Chinese and French, delivering SRT, VTT, iTT and TTML with characters-per-second and line length under control.

How it works

1

Scope and spec

You send the video and target profile. I confirm frame rate, timecode, caption style and the delivery formats you need.

2

Author

I time and write the captions or subtitles to the reading-speed, line-length and positioning rules for the target.

3

Encode and wrap

I produce the deliverables: SCC, MXF OP1A embed, SMPTE ST 2052-1 or DCP XML, plus a burned-in preview.

4

QC and deliver

I decode the result independently with caption-inspector, fix anything that drifts, and deliver with a report.

Three-layer QC before anything ships

Broadcast and cinema files fail on decoders, not in an editor preview. Every delivery goes through three passes and an independent decode.

1. Rough pass

Spot and draft every caption against the script, source audio and shot changes.

2. Alignment and timing

Tune reading speed, line breaks and positioning; align to shot changes and clear names and lower-thirds.

3. Independent senior QC

Decode the result on a separate decoder, check conformance to the target spec, and sign it off.

✓Characters-per-second held to spec on every event
✓Safe-title and safe-area violation check per caption
✓Multi-device and projection playback testing
✓Independent CEA-608 and CEA-708 decode with caption-inspector
NDA and secure handling for unreleased films and pre-air episodes; screeners are deleted on delivery.

Frequently asked questions

Which languages do you subtitle?

I subtitle into native Vietnamese, and I also work across English, Chinese and French. As a Vietnamese translator my strongest, publish-ready target is Vietnamese.

Do you translate from a template or from the video?

Either. I can translate from a timed template (SRT, VTT or a bilingual file) or spot and time from the video, always keeping the reading speed and line length comfortable for the viewer.

How much does subtitle translation cost?

Indicative rates are about $0.04 per word, or roughly $4 per minute of video. Send the file and target language and I send an exact quote within 10 minutes.
