The Post-Production Bottleneck for UK Media Companies
British independent production companies and in-house media teams produce content at scale: corporate video series (12-52 episodes), YouTube channels (weekly uploads), documentary projects, and branded content for streaming platforms. Yet post-production is a persistent constraint.
A typical 30-minute documentary requires: (1) Offline edit (assembly, colour reference, basic audio): 25-30 hours; (2) Colour grade (timing, look development, shot-to-shot consistency): 20-25 hours; (3) Audio mixing and sound design: 15-20 hours; (4) Subtitle creation and encoding: 5-8 hours; (5) Format delivery (ProRes 422, H.264, DCP spec verification): 3-5 hours.
Total: 70-90 hours of specialist work. A UK editor earning £40k/year costs £19/hour (loaded). A 90-hour project consumes £1,700 in labour alone—plus software licenses (£3-5k annually for DaVinci Resolve Studio, Premiere Pro, After Effects).
For a media company producing 10 projects annually, in-house post-production costs £100-150k/year in salaries alone, plus 15-20% equipment and software overhead.
The timeline crunch is equally material: a UK freelance editor booked 2-3 weeks in advance. A production company cannot scale by hiring; each new editor requires training, equipment investment, and studio space. Instead, post-production becomes a bottleneck that delays publication by 3-4 weeks per project.
What Gets Outsourced: The Post-Production Workflow
Core Post-Production Functions
Video editing: assembly, pacing, colour references for grading. Editors use Premiere Pro (Adobe) or DaVinci Resolve (Blackmagic) to ingest raw footage, organize clips, apply rough cuts, and structure narrative.
Colour grading: shot-to-shot colour timing, LUT application, grade consistency across scenes, creative look development. The colourist uses DaVinci Resolve's advanced tools (Fusion integration, node-based grading, scopes) to achieve broadcast-quality results.
Audio mixing: dialogue EQ, music level balancing, effects layering, surround sound preparation (5.1, Dolby Atmos). Mixing requires monitoring on calibrated speakers; remote mixing via file transfer is standard industry practice.
Subtitle creation: transcription, time coding, formatting (SRT, VTT, Closed Caption specs). Subtitles must sync to video frame-accurately and meet platform-specific requirements (YouTube, Netflix, BBC iPlayer).
Effects and motion graphics: title sequences, lower-thirds, animated graphics, rotoscoping, visual effects compositing. Done in After Effects or DaVinci Fusion.
Format delivery: exporting final masters in multiple formats (ProRes 422 for archival, H.264 for streaming, DCP for cinema), verifying metadata, creating ISO files for physical media.
What Stays In-House
Creative direction and editorial decisions: the producer or director makes final calls on pacing, music selection, graphic design, and visual style. Our team executes decisions, not makes them.
Colour grading creative look (high-level): the director or DP (cinematographer) provides reference stills or verbal direction ('film noir, desaturated'; 'warm, golden-hour aesthetic'). The colourist interprets and executes.
Voice-over recording and ADR (Automatic Dialogue Replacement): typically done in-house or via specialized ADR studio. File is delivered to our team for mixing.
Kenya's Creative Talent Pool and Cost Model
Kenya has emerged as a hub for African media production. Nairobi hosts iHub (innovation community), Konza Technopolis (tech corridor), and a growing pool of trained editors, colourists, and sound engineers trained on industry-standard software.
Why Kenya for post-production? (1) Time zone advantage: a Nairobi team working 08:00-17:00 EAT overlaps 4-5 hours with UK morning (GMT). A producer submits materials Monday; the team begins Tuesday morning and delivers by Wednesday evening. (2) Cost: a senior video editor in Nairobi earns £8,000-12,000/year; a UK equivalent earns £32-40k/year. A colourist in Nairobi earns £9,600-14,400/year; UK equivalent £40-50k/year. (3) Talent availability: unlike UK freelance markets (booked 2-3 weeks out), Nairobi-based team availability is more flexible; a production can often start within 48 hours.

File Transfer, Collaboration, and Workflow
The Challenge: File Size and Bandwidth
A typical post-production project involves massive files: raw 4K footage (600MB-2GB per minute), proxy files (100MB/minute), edit timelines (500MB-2GB per project), and final masters (500MB-2GB per hour of video).
Uploading a 30-minute project (100GB of source material) via standard broadband (10 Mbps upload) takes 24+ hours. Even with optimised proxies, initial file transfer is a logistical challenge.
Solution: Proxy-Based Workflows
Standard practice in remote post-production: the production company uploads low-resolution proxies (10-50MB/minute, H.264 codec) instead of full-resolution footage. Our team edits and grades against proxies. On final delivery, the edit decision list (EDL) or timeline XML is used to automatically conform and re-render the master from the original high-resolution files.
Tools: Adobe Premiere Pro's Dynamic Link and EDL export; DaVinci Resolve's timeline XML export; Final Cut Pro's XML interchange.
Collaboration Workflow Example: 30-Minute Documentary
- Monday 10:00 GMT: Producer uploads 100GB of 4K source material and proxies (5GB) to secure cloud storage (Google Drive, Frame.io, or Aspera).
- Monday 14:00 GMT: Treba's editor logs into storage, reviews raw footage, creates offline edit against proxies, and uploads preliminary cut (DaVinci timeline XML) back to cloud.
- Tuesday 08:00 EAT: Producer reviews preliminary cut, provides feedback ('speed up pacing in Act 2, reduce runtime to 28 mins').
- Tuesday 09:00 EAT: Editor revises timeline, re-exports XML.
- Tuesday 14:00 EAT / 12:00 GMT: Producer approves locked cut. Colourist begins grading. Simultaneously, audio mixer begins dialogue and music sync.
- Wednesday 12:00 EAT / 10:00 GMT: Grade and audio mix complete. Treba's lead editor exports final timeline, conforms original resolution files, and delivers ProRes 422 master (2-3GB).
- Wednesday 15:00 GMT: Producer receives master, verifies colour and audio, uploads subtitles for integration.
- Thursday morning GMT: Final deliverables (streaming H.264, DCP, archive ProRes) prepared and delivered.
- Total timeline: 3.5 days from raw footage to final delivery. UK in-house: 2-3 weeks.
Quality Assurance and Delivery Specifications
QA Checkpoints
Treba's QA process includes: (1) Colour accuracy: graded master is verified on calibrated monitors (BenQ SW series or similar) in a dark room, meeting Rec.709 broadcast specs; (2) Audio sync: dialogue, music, and effects are checked frame-by-frame for synchronisation; (3) Subtitle sync: subtitles are spot-checked at 5-minute intervals; (4) File integrity: masters are verified for corruption, proper metadata, and frame count accuracy.
Delivery Formats
Streaming (YouTube, Vimeo): H.264, 1080p or 4K, 23.98 fps or 25 fps, stereo audio, AAC codec, YouTube-recommended bitrate (15-50 Mbps for 4K).
Broadcast (BBC, ITV, Channel 4): ProRes 422 HQ, 1920x1080, 25 fps, 16-bit audio (BWF format), full EBU R128 loudness compliance (-23 LUFS).
Archive: ProRes 422, full resolution (4K if shot in 4K), uncompressed audio, comprehensive metadata (timecode, colour space, frame rate).
DCP (Digital Cinema Package): optional, for festival submission or theatrical release. Requires specific codec (JPEG2000), colour space (DCI), and metadata structure.
Turnaround SLAs
Standard project (30-50 minute video, Offline Edit + Grade + Audio): 7-10 business days from locked cut to final master.
Rush project (additional fee): 48-72 hours.
Unlimited revisions included in project scope (up to 3 rounds). Scope creep beyond that: charged at £100/hour.
Case Study: Cost and Timeline Comparison
Scenario: 12-Episode YouTube Series (25 min each)
A UK media production company produces a 12-episode documentary series for YouTube (total 300 minutes). Each episode requires offline edit, colour grade, and audio mix.
In-House Approach (UK)
Year 1 hiring: Senior Editor (£40k) + Colourist (£45k) + Sound Mixer (£38k) = £123k salaries. Add 20% burden, software, and equipment: ~£165k total.
Timeline: Each episode (25 mins) requires 60-70 hours post-production. One editor working alone: 60-70 hours / 40 hours/week = 1.5-1.75 weeks per episode. 12 episodes = 18-21 weeks. In practice, with revisions and concurrent projects, timeline stretches to 6-7 months.
Outsourced Approach (Nairobi)
Team cost: 5-person team (Editor, Colourist, Mixer, Junior Editor, Motion Graphics) = £65.8k annual cost. Can process 2-3 episodes simultaneously.
Timeline: Submit Episode 1 Monday; receive locked cut Wednesday. Grade/mix Thursday-Friday. Deliver final master Friday evening. Submit Episode 2 same Monday; deliver Tuesday. Concurrent processing reduces total project timeline to 6-8 weeks (instead of 6-7 months).
Cost per episode: £5,500 (300k / 12 episodes / 4.5 projects per team slot). UK equivalent cost: £13,700 per episode.
Project total: Nairobi £66k for year + 8 weeks timeline. UK in-house: £165k + 6-7 months timeline.
Key takeaways
• Post-production is a critical bottleneck: a 30-minute video requires 60-80 hours of editing, grading, and audio—work that delays UK productions by 3-4 weeks. • Kenya's creative talent pool (trained on DaVinci Resolve, Premiere Pro, After Effects) offers similar quality to UK freelancers at 75-80% lower cost. • Proxy-based workflows enable remote post-production: source files stay in-house; proxies (low-res) are edited and graded remotely; final masters are conformed locally. • A 5-person post-production team in Nairobi costs £65.8k annually vs. £249-282k in the UK—a saving of £179-220k per year. • Turnaround SLA: 7-10 business days from locked cut to final master.
Time zone overlap (4-5 hours GMT-EAT) enables rapid feedback cycles.
