# Post-production Services > Professional video and audio post-production: editing, colour finishing, graphics, sound, subtitles, multilingual versioning, mastering and technical QC. Source: https://www.globaltranslations.org/linguistic-services/post-production Our role ### Post-production That Brings Every Element Together Post-production begins once footage, audio or other source assets exist. It can involve assembling and refining the picture, correcting colour, replacing on-screen text, editing and mixing sound, adding captions, preparing language versions and mastering files for delivery. For international content, these activities must stay synchronised. A revised cut can affect subtitle timings, a translated title can change the graphics layout, and a new voice track can require sound and picture adjustments. PangeaVox manages those dependencies across specialist teams rather than leaving you to coordinate separate suppliers. Capabilities ### Video, Audio & Multilingual Post-production #### Video Editing & Picture Conform Assemble approved footage, refine pacing and transitions, apply cut changes and conform picture to an agreed reference or edit decision. #### Colour Correction & Finishing Coordinate colour balancing, shot matching, grading and SDR or HDR finishing according to the source, destination and approved colour workflow. #### Motion Graphics & On-screen Text Prepare titles, lower thirds, supers, end cards and translated graphic replacements, preserving timing, brand guidelines and legibility. #### Audio Post-production Edit and restore dialogue, process voices, integrate music and effects, mix and master audio, and verify loudness and sync. #### Subtitles, Captions & Accessibility Synchronise approved subtitle and caption assets, check readability and presentation, and integrate accessibility deliverables into the agreed output. #### Multilingual Versioning & Finishing Manage language-specific picture, audio and text versions, replace localised assets, check consistency and package the resulting masters. Work is scoped to the source assets and delivery requirements. Colour grading, visual effects, animation, restoration and specialist sound formats are allocated appropriate production resources and acceptance criteria during quotation. Flexible engagement ### Three Ways to Commission Post-production #### Video Editing & Finishing Edit footage, update titles and graphics, perform colour finishing and prepare a reviewed video master. **Deliverables:** Approved picture master and agreed exports. #### Multilingual Media Versions Bring together localised graphics, subtitling, new voice tracks, synchronisation, sound finishing and version-specific QC. **Deliverables:** Market-ready audio and video versions in the agreed formats. #### Audio Editing, Mix & Master Restore and edit recordings, mix dialogue, music and effects, and deliver technically checked audio masters. **Deliverables:** Finished audio files, agreed stems and optional QC documentation. Applications ### Built for International Media Workflows #### E-learning & Training Consolidate edited lessons, translated titles, narration, subtitles and accessibility assets across modules and languages. #### Advertising & Brand Content Prepare regional edits, translated supers, end cards, sound mixes and platform-specific formats for approved campaigns. #### Film, Documentary & Streaming Coordinate picture conform, audio finishing, subtitle integration and technical delivery against an agreed distributor specification. #### Podcasts, Interviews & Recorded Events Edit speech, restore and balance audio, synchronise supporting visuals and prepare approved editions for distribution. Technical assurance ### Delivery Specifications & Quality Control We agree the applicable broadcaster, streaming platform, accessibility or client delivery specification before finishing begins. The final review covers the relevant picture, sound, text and file-integrity requirements, rather than relying on an isolated technical pass. - **Picture:** frame rate, resolution, aspect ratio, colour space and transform, graphics safe areas, version matching and export integrity. - **Sound:** intelligibility, synchronisation, channel configuration, programme loudness and true peaks, measured to the applicable specification using [ITU-R BS.1770-5](https://www.itu.int/rec/R-REC-BS.1770-5-202311-I) and, as relevant, [EBU R 128](https://tech.ebu.ch/publications/r128) or [ATSC A/85](https://www.atsc.org/atsc-documents/a85-techniques-for-establishing-and-maintaining-audio-loudness-for-digital-television/). - **Subtitles and captions:** correct language, text, timing, reading speed, line breaks, placement and the required delivery format, including WebVTT or [IMSC 1.2](https://www.w3.org/TR/ttml-imsc1.2/) where specified. - **Accessibility:** agreed caption and audio-description deliverables, with [WCAG 2.2](https://www.w3.org/TR/WCAG22/) criteria where applicable to web media. - **Files and versions:** codec, container, naming, metadata, checksums where required and the approved language/version matrix.
