What if the edit changes later?
The previous sound mix must first be synced to the new edit, so that all new cuts are reflected in that mix. This makes reconforming much faster and much more reliable on our side.
01
Notify the sound department before making a new turnover
02
Get the latest draft sound mix from sound post
03
Sync that mix to the updated picture version before making new cuts
04
Export EDL before recut
05
Make the recut using that synced mix, so the previous sound mix is cut together with picture
06
Export a new AAF containing only this updated mix version with all the cuts
07
If you added new shots, include their new sounds in the AAF on separate tracks
08
Do the same if music changed, voice placement changed, or any new material was introduced
09
Before export, remove everything except the updated mix and newly added elements
10
Export EDL from new version

Naming example: PROJECT_NAME_EDL_OLD_DD_MM_YY and PROJECT_NAME_EDL_NEW_DD_MM_YY
Sound Post Workflow

A cleaner handover means better sound work

A properly prepared AAF, organised audio tracks and a reliable reference video allow the sound team to reconstruct the edit accurately and begin creative work without first repairing the turnover.

Clear delivery helps prevent missing media, broken sync, incorrect timecode and unnecessary reconforming, leaving more time for dialogue, sound design, Foley and the final mix.

01
AAF export

Carries clip timing, edit structure and audio media into the sound session.

02
Reference video

Provides a stable picture reference with matching frame rate, timecode and sync.

03
Track organisation

Keeps dialogue, voice-over, music and effects clearly separated.

04
Re-edit safety

Makes later picture changes easier to compare and conform.

FAQ

Common questions about delivery for sound post-production

Practical answers about AAF export, reference video, sync, timecode, track organisation and later picture changes.

What is an AAF file in sound post-production?

AAF (Advanced Authoring Format) is used to transfer the audio structure of your edit into sound post-production.

It includes clips, timing, track layout and metadata needed to rebuild the timeline in another system.

Why is AAF important for sound post-production?

It allows the sound team to reconstruct the edit exactly as it was in the picture timeline.

Without it, the session has to be rebuilt manually, which is slower and much less reliable.

Why do AAF files break or import incorrectly in Pro Tools?

Each editing software exports AAF differently.

A project exported from Avid, Premiere or DaVinci Resolve may behave differently even if the timeline looks the same.

During import, clips may lose metadata, tracks may collapse or split differently, and some elements may not translate as expected.

Why should audio be synced before exporting AAF for sound post?

When audio is already synced in the edit, it gives a clear and reliable structure for sound post.

In some high-end workflows, syncing is done later using specialised tools, but in many real-world projects it's faster and more stable to sync directly in the editing software.

It also reduces the need for heavy reconstruction later and makes the handover much cleaner.

Why does track organisation matter in AAF export?

Keeping dialogue, VO, music and SFX on clearly organised tracks makes the project readable and predictable before it even reaches sound post.

When an AAF is imported, stereo tracks can be split into mono, clips may lose naming consistency, and material can end up scattered across multiple tracks.

In these situations, the sound team often has to rely on visual inspection to understand what each clip contains.

If the timeline is well organised from the start, it becomes much easier to rebuild the structure inside the sound session, saving time and avoiding confusion.

Even a basic structure at the editing stage significantly improves speed, clarity and reliability during sound post-production.

What happens if the AAF is incorrect?

An incorrect AAF can result in missing files and metadata, broken sync or collapsed track structure.

This often leads to manual fixes, reconforming or rebuilding parts of the timeline, which slows down the process and increases the risk of errors.

Why do you ask to keep all original audio, even if it sounds unusable?

Even rough or noisy sync sound contains important information about timing, space and performance.

In many cases it helps to reconstruct scenes, guide ADR or even reuse parts of the original recordings.

Silence or missing audio removes that reference completely and makes the process much harder.

Why do you request timecode burn-in on the video?

Timecode burn-in allows the sound team to quickly identify exact frames during editing and mixing.

It is especially useful for communication between departments when discussing specific moments in the timeline.

Without visible timecode, feedback becomes slower and less precise.

What is an EDL file and when is it useful?

An EDL (Edit Decision List) contains timing information about cuts and edits in the timeline.

It can be used in sound post-production to help reconstruct or compare different versions of the edit.

In some workflows, EDL is especially useful for dialogue editing and conforming.

Why use a sync pop?

Sync pop is a simple but reliable way to check sync between audio and picture.

In most cases it may not be needed, but when something goes wrong — frame rate changes, timeline shifts or export issues — it becomes a clear reference point to detect and fix sync problems quickly.

Why do you request H.264 video if Pro Tools works better with DNxHD or ProRes?

Pro Tools works more efficiently with codecs like DNxHD or ProRes, as they are less compressed and easier to decode in real time.

However, H.264 is still widely used for delivery because of its smaller file size, fast upload speeds and simple export workflow for editors.

In practice, H.264 is often the easiest exchange format: the editor can export one lightweight reference video for the director, producer and sound team without creating multiple versions.

On the sound side, the reference video can then be converted to DNxHD or ProRes when needed for better performance in Pro Tools.

Soundshot Studio also provides a small free tool for this sound-side step: Soundshot Video Prep.

Why may we ask to split long films into reels?

For long-form projects (films, documentaries, series), it’s often helpful to split the timeline into 20–30 minute reels.

This is a common workflow in professional sound post-production and is still widely used in cinema and high-end projects.

If your project is already structured this way — perfect.

If not, it’s usually easy to create reels at the final stage.

For projects over 60 minutes, working in reels significantly improves stability and efficiency during editing and mixing.

It helps to:

  • keep sessions stable and responsive
  • allow parallel work across multiple reels
  • make revisions easier and safer
  • avoid timecode overlaps and confusion
Why isn’t Final Cut Pro included in the Delivery Guide?

Final Cut Pro does not support AAF export natively, which makes direct transfer to sound post-production more complicated.

To prepare a project for sound post, an additional tool is required to convert the timeline into an AAF-compatible format.

Depending on the workflow, this may involve exporting XML from Final Cut and converting it using third-party software X2Pro before bringing it into Pro Tools.

If you’re working in Final Cut Pro, it’s best to clarify the workflow in advance to avoid issues during handover.
