End-to-end manual for scoring episodic TV — DAW templates, version control, stems, metadata, and IMF/Atmos delivery, using HBO's Harry Potter reboot example.

Hook: Why scoring episodic TV feels broken — and how to fix it

Composers and post teams waste days reconciling conflicting cue versions, chasing lost stems, and rebuilding DAW sessions for a single episode. When a high-profile show like HBO's Harry Potter reboot (scored by Hans Zimmer and collaborators) cycles notes across multiple episodes, those inefficiencies multiply. This manual gives an end-to-end soundtrack production workflow you can implement in 2026 to go from composition to broadcast-ready delivery without rework or late-night panic.

What you'll get in this guide

Concrete DAW session settings and templates for episodic scoring
Practical collaboration and version control strategies
Delivery checklists for stems, metadata, and broadcast specs (2‑track, 5.1, Atmos, IMF)
Modern 2026 trends: cloud DAWs, AI-assisted stems, immersive metadata (ADM), and IMF adoption
Example file naming, manifests and automation snippets you can copy

The production topology: roles, handoffs, and timing

Before you touch a DAW, map the people and handoffs. For an HBO-level episodic workflow (use the Harry Potter reboot as our example), typical roles are:

Composer / Lead Composer — creates themes, sketches, and final cues
Orchestrator / Arranger — prepares cues for live players or mockups
Supervising Music Editor — aligns cues to picture, prepares M&E, delivers editorial versions
Scoring Mixer — mixes stems and delivers premix assets
Re-recording Mixer (Final Mix) — integrates music with dialogue and effects for final show mixes
Music Clearance & Metadata Manager — manages rights, cue sheets, and metadata

Scheduling and episode cadence

For an episodic series with 8–10 episodes, assume rolling deadlines: editorial locked for Episode N while scoring for N+1 begins. Build a 2‑week buffer for deliverables like M&E and stems so localization and re-recording mixers have time. For large shows (e.g., HBO), set weekly scoring milestones and freeze cues 72 hours before stem delivery.

DAW: session settings and templates that scale

Your DAW template is the backbone. Treat it as a software release branch: immutable, versioned, and documented.

Global session settings (must-haves)

Sample rate: 48 kHz (standard for TV deliverables). Use 96 kHz only if your show spec requires native high-res — but deliver resampled 48 kHz masters.
Bit depth: 24-bit working; render masters at 24-bit WAV. Archive stems and masters at 24-bit (or 32-bit float for DAW project archives).
Frame rate / Timecode: Set the session to the project's frame rate (23.976, 24, 25, 29.97). Always use linear timecode (LTC) and an anchored timecode offset matching editorial (example: 01:00:00:00).
Clocking: If using external converters, slave DAW clock to external reference. For networked I/O use AES67/Dante sync in 2026 environments.
Tempo map: Import picture's tempo or use click tracks for tempo-based editorial. Freeze tempo map once cue is approved.

Track layout and bussing (template recommendations)

Organize by folders: Orchestra_MIDI, Orchestra_Audio, Synths, FX, Vocals, Mix_Busses
Color-code folders and tracks; stick to a color legend documented in the template
Pre-create submix busses for stems: MX_FullMix, ST_Music, ST_Beds, ST_Perf (performance/stems for soloists), and M&E bus
Set up returns for reverb/delays with preconfigured routing to facilitate consistent ambience across cues

Plugins, presets, and CPU hygiene

Use plugin version pins documented in a plugin manifest. For large projects freeze heavy instances (or bounce to audio) before archiving versions. Maintain one static plugin folder per project to avoid mismatches; avoid unnamed 3rd-party trial plugins in deliverable stems. Also consider device security and firmware hygiene — see analysis on firmware & power modes for audio devices.

Cue naming convention (copyable)

SHOW_EP##_Cue##_ShortDesc_v###_YYYYMMDD

Example: HP_EP03_Cue05_DumbledorEntrance_v004_20260112.wav

Version control for audio projects: treat cues like code

Traditional file servers don't cut it in 2026. Adopt a hybrid of Git-like practices and large-file transfer tools.

Strategy overview

Small files / text (notation, cue sheets, metadata): store in Git (GitHub/GitLab) with branch protection and PR reviews
Large binary files (DAW sessions, audio stems, sample libraries): store with Git LFS or an object store (S3-compatible) and use signed manifests
File transfer: Use Aspera or Signiant for master deliverables; use Rclone/rsync for internal syncs; use cloud DAWs (e.g., sessions in Avid Cloud Collaboration, Amazon Music Studio integrations) for remote scoring to reduce transfers — and test network tools (see portable comm & network kits) to validate throughput.

Branching, tags and release artifacts

Create branches per episode: ep03-scoring. Use tags for release milestones: ep03_stems_v001. Each release should include a manifest.json with checksums, file list, and metadata.

{
  "show": "HP_Reboot",
  "episode": "03",
  "release": "stems_v001",
  "files": [
    {"name":"HP_EP03_Cue05_FullMix.wav","sha256":"...","channels":"stereo","rate":"48kHz","bits":24},
    {"name":"HP_EP03_Cue05_MusicStem.wav","sha256":"...","channels":"5.1","rate":"48kHz","bits":24}
  ]
}

Collaboration: real-world procedures used on big shows

High‑profile productions like the HBO Harry Potter reboot coordinate dozens of music assets per episode. Here are proven steps to avoid version chaos.

Weekly scoring ritual

Monday: Composer delivers updated cues (mockups) to Music Editor with change log.
Tuesday: Editorial places cues to picture; notes collected via a shared ticketing system (Jira or ShotGrid).
Wednesday: Composer revises and produces stems for Scoring Mixer.
Thursday: Scoring Mixer delivers premix (wet/dry) for showrunner notes.
Friday: Approved stems released to Post as signed release artifact.

Notes management

Use a centralized notes tracker. Each note links to a specific cue version, timecode, and change severity. Implement a simple convention: NOTE-EP03-005 = Episode 3, cue 5. This enables traceability from picture note to delivered file.

Remote musicians and sample libraries

In 2026, remote orchestration and cloud libraries are mainstream. Use locked template patches and send transmits as consolidated audio to musicians for overdubs. For live sessions, use AES67 or Dante bridges to connect remote stages and record direct into your DAW master session. If contributors need compact recording kits, see field reviews such as the PocketCam Pro and compact-home-studio guides (home studio kit review).

Mixing and stems: definitions and best practices

Stems are the currency of post. Define the stem set early with Supervising Music Editor and Re-recording Mixer.

Common stem configurations

Full Mix — Two-track master stereo (or Atmos bed) with everything mixed as intended.
Music Stems — Submixes: Orchestra, Soloists, Synths, Percussion, Choir (deliver as stereo and as discrete multichannel if needed).
M&E (Music & Effects) — Music consolidated without dialogue or tightly integrated sound-design elements for international dubbing.
Atmos / Immersive — ADM/BWF files or Dolby Atmos ADM files with bed and objects for streaming platforms (when requested).

Stem delivery specs (practical defaults)

Format: Broadcast WAV (BWF) with iXML and INFO chunks populated.
Sample rate: 48 kHz; Bit depth: 24-bit.
Channel layout: stereo or 5.1 as specified; include interleaved and discrete renders if requested.
Name each stem with metadata: SHOW_EP##_Cue##_StemType_v###_YYYYMMDD.
Include a cue sheet CSV alongside stems with start timecode, duration, composer, publisher, and ISRC (where assigned).

Automating stem exports

Most DAWs support batch export. Save export presets with channels, fades, and dither settings. Example Pro Tools: create Bounce Templates for each stem type and run via AAX offline bounce for consistent file headers.

Metadata and cue documentation (non-negotiables)

Without accurate metadata, deliveries become unusable. Treat metadata as part of the deliverable.

Essential metadata fields

Show Title, Episode Number, Cue Number, Cue Title
Composer(s), Orchestrator(s), Conductor
Publisher, Rights Holder, ISRC
Start/End Timecode, Duration
Sample Rate, Bit Depth, Channel Layout
Stem Type and Mix Version
Checksum (SHA256) for each file — include machine-readable checksums and validate with CI (see automation & CI approaches).

Files that must accompany every release

manifest.json (machine-readable manifest with checksums)
cue_sheet.csv (human-readable cue list)
readme.txt (tool chain and plugin versions)
approval_signed.pdf (signed cue approval from showrunner or supervising music editor)

Broadcast specs, loudness and compliance (2026 standards)

Deliver according to platform specs. In 2026, most streamers and premium broadcasters accept Dolby Atmos deliverables and require strict loudness compliance.

Loudness and metering

Primary loudness: ITU-R BS.1770-4 and LUFS measurement
Targets: follow platform specs; common default for streaming is -14 LUFS integrated for final audio with true peak < -1 dBTP (confirm per platform)
Use reference meters that log measurements into your deliverable metadata and attachment reports

Immersive and object-based audio

Dolby Atmos and ADM metadata are mainstream in 2026. If a platform requests Atmos, deliver an ADM BWF package and an associated IMF (Interoperable Master Format) package when required. Ensure ADM metadata is embedded and objects are appropriately named and documented in the manifest.

Interoperable Master Format (IMF)

IMF simplifies versioning for multiple language/localization masters. For large episodic shows, request IMF specs from post and produce a base IMF bundle with audio assets and track files that can be recompiled for regional versions. For more on archival and master packaging, see archiving master recordings.

Archiving, checksums and long-term storage

After delivery, archive everything immutably.

Store raw DAW sessions, sample libraries versions, exported stems, and manifests in cold storage (S3 Glacier or LTO for long-term archive) — learn more about archiving best practices at Archiving Master Recordings.
Generate SHA256 checksums for every file and store manifests in both the repo and as a signed PDF
Document playback instructions: DAW version, plugin versions, OS, and recommended workstation image

AI and 2026 trends that change scoring workflows

Late 2025 and early 2026 solidified several trends that affect soundtrack workflows:

AI-assisted composition and stems separation: Tools now accelerate mockups and can separate stems from temp mixes, but they must be validated — AI outputs still need human creative oversight and rights checks. Consider local and on-device storage needs for AI workflows (storage for on-device AI).
Cloud-native DAWs: Sessions hosted in the cloud reduce file transfers and allow real-time remote collaboration with low latency; still pair with local backups and strict versioning. Read cloud & local kit reviews such as compact home studio kits when building remote contributor setups.
Wider IMF adoption: Studios increasingly require IMF packages for episodic masters to streamline regionalization.
Standardized metadata: ADM and iXML are common; metadata-first workflows reduce rework during localization.

Case study: Scoring a cue for HBO's Harry Potter reboot — practical flow

Scenario: Episode 3 needs an 80‑second magical suspense cue. Here's a tight, practical flow used at scale.

Composer sketches theme in Logic and exports a picture-locked MP4 mockup named HP_EP03_Cue05_Mock_v01.
Music Editor places mockup in editorial timeline and leaves frame-accurate notes via ShotGrid. Notes are tagged NOTE-EP03-005.
Composer finishes arrangement, consolidates orchestral MIDI to audio renders for CPU stability, and saves session as HP_EP03_Cue05_Session_v02.protools (or .logicx).
Run automated export: generate FullMix stereo, Orchestra stem (stereo), Percussion stem (stereo), and M&E. Each file includes iXML and a SHA256 checksum in the manifest.json.
Upload to staging S3 via Aspera and create a GitHub release linking the manifest and cue_sheet.csv.
Scoring Mixer reviews; a single revision is required. Final stems are approved and a signed approval PDF is attached to the release.

Deliverable checklist (copy & use)

Master Full Mix WAV (48kHz/24-bit) — interleaved stereo
Music stems: Orchestra, Percussion, Synths, Choir (as required) — stereo and 5.1 if requested
M&E: music without dialogue
ADM/Atmos packages when requested (ADM BWF or Dolby Atmos ADM)
cue_sheet.csv and manifest.json (with SHA256 checksums)
readme.txt with DAW and plugin versions
Signed approval form

Practical tips that save hours

Embed timecode and cue ID into each exported filename — this prevents confusion when editors assemble long reels.
Keep a single, documented template per show and refuse ad hoc session formats.
Use automated checks: a CI job that validates manifest checksums and confirms iXML is present before accepting release artifacts — pair that with automation best practices.
Maintain a plugin manifest and a containerized workstation image for exact rebuilds if you need to regenerate stems years later.
Schedule a weekly “deliverables freeze” meeting to lock stems for localization and final mix workflows.

Future-proofing: what to adopt now

Adopt metadata-first workflows, prepare to produce ADM/Atmos beds, and implement IMF-ready asset packaging. In 2026 these are not optional for premium episodic shows. Invest in automated manifests, reliable LTO/Cold cloud archiving, and hashed releases.

"Treat audio like code: version it, sign it, and automate your checks." — Recommended production mantra for episodic scoring in 2026

Final checklist before hand-off (quick scan)

All stems rendered at 48kHz/24-bit with iXML populated
FullMix and M&E created and QC'd for loudness and true peak
Manifest.json with SHA256 checksums included and uploaded
Readme and plugin manifest attached
Signed approval PDF from supervising music editor or showrunner
Assets archived to cold storage and Git LFS/repo tagged

Closing: adopt a disciplined workflow and reduce risk

Scoring an episodic show like HBO's Harry Potter reboot at scale requires more than creativity — it requires reproducible, auditable workflows. Use the DAW templates, naming conventions, versioning practices and delivery checklists above to reduce friction and meet broadcast specs reliably. The investment pays back in faster approvals, fewer re-renders, and easier long-term archival retrieval.

Actionable next steps (start now)

Download or create a show-level DAW template with the settings above.
Create a manifest.json template and integrate checksum validation into your release process. See automation patterns at automation & CI approaches.
Set up a cloud staging bucket with Aspera/Signiant and test a full stems delivery with your post team — validate networking with portable comm testers and consider local-first tools (local-first edge tools) for offline failover.
