The Studio-Grade Workflow
1. Ingest & Setup
Upload your source (ProRes, XDCAM, etc.) and reference materials. We align on style guide, reading speed, speaker labeling, and SDH conventions before production starts.
2. Spotting & Segmentation
We set timing rules, safe areas, and segmentation for optimal readability, so subtitles land naturally with clean line breaks and consistent pacing across episodes.
3. Transcription & SDH Authoring
Dialogue is transcribed and structured to spec. For SDH, we add speaker IDs, non-speech information (SFX/music), and accessibility cues while preserving tone and intent.
4. Timing & Conformance
Captions are timed frame-accurately to picture and mixed audio. We enforce reading-speed limits, punctuation rules, and formatting consistency across the entire catalogue.
5. Dual-Layer QC
Two-stage review for accuracy, timing, readability, and SDH logic. Optional in-context QC against your player (OTT, broadcast playout) to catch platform-specific rendering issues.
6. Final Delivery
Delivered exactly in the format your team needs: WebVTT, SRT, TTML/IMSC1, EBU-STL, SCC and more. We also support burn-in and packaged deliveries for platforms and broadcasters.
