Conform and Assembly
Conform updates an existing sound edit for a revised picture cut. Assembly finds the original recordings for an edit and prepares the audio for Pro Tools or PTX export.
Conform
Copy an existing sound edit to match a revised picture cut.
Assembly
Match an edit to original recordings and prepare the audio for output.
Rushes
Add and inspect the source recordings used for matching.
Assistant
Search local transcripts, audition a line and select an excerpt.
Use them separately or together. Assembly can work across a complete edit, with new material identified by Conform, or with selected Pro Tools clips through Quick Spot.
For example, a recut might move an existing scene and add a new one. Conform copies the existing sound to its revised positions; Assembly finds recordings for the new material. Review the results against picture before delivery.
The Conform plan compares the existing edit with its new destination.
Compare a revised cut
Load the old and new editorial versions. Comparison sources include CMX EDL, Final Cut Pro 7 XML, flattened FCPXML v1, AAF and saved Pro Tools PTX sessions. Picture or timed guide audio can be compared when edit lists are unavailable.
CMX EDL support includes FILE32 and FILE128. Flattened FCPXML can be supplied as .fcpxml or .fcpxmld; unsupported structures are reported during import.
Save the Pro Tools session before loading its PTX if you need recent changes included. PT EDL reads the saved file, so unsaved edits in the open session are excluded.
Load multiple guides or reels and choose the old and new tracks independently. Embedded picture audio is initially off and can be enabled as a guide.
Check the old and new offsets, set guide placement separately, and confirm a known sync point. For a single recut, source timecodes can map the existing version to the new record timecodes.
Edit Lists shows the events in each imported edit.
Offsets, with a worked example
An offset is the amount an edit list must shift to line up with the session timeline.
If the New list starts at 01:00:00:00 and belongs at 01:30:00:00 in the session, enter an offset of 00:30:00:00.
Set the Old and New offsets independently. Each loaded reel can have its own offset, and guide placement is separate. Check the frame rates as well: an offset changes placement, not playback rate.
Sync tolerance controls how closely events must agree to match. Optimisation affects how the conform plan is built; it does not change which events match.
Set an individual offset for each loaded reel.
Review the changes
Choose Calculate Conform Plan, then inspect the proposed moves, extensions and new-audio ranges. The graphical plan shows their arrangement, Edit Lists shows the imported events, and Tracks provides audio and video context.
Result Details has Changes, VFX Findings and Full Report tabs. Filter the Changes list by All changes, Moves, New audio, Extensions or Reuse.
KEEP identifies reused material copied to the destination. COPY identifies material copied to a changed position. INSERT identifies a range without a matched old source, where sound needs to be found or added.
Head and tail extensions show the extra source coverage needed around reused ranges. Review these along with any unused old material. The original edit remains at its source position.
Use Save Note to attach a remark to a change, or Select in Pro Tools to highlight the corresponding event in the open session. Export reports as text, CSV or HTML.
Picture and audio checks help with review. Sampled picture checks do not verify every frame, so confirm the result against picture and listen before delivery.
Changes lists the moves, extensions and new audio in the plan.
Tracks gives the selected material timeline context.
Full Report lists the operations in the calculated plan.
Recognise VFX names
Set naming rules to recognise shot and version information in clip, reel or source-file names. Preview the results against the filenames in your production.
VFX Findings identifies recognised version changes alongside the timing changes in the conform plan. A new render may also have moved or changed length.
Sampled picture checks help identify render changes to inspect. They leave the conform timing operations intact and do not verify every frame.
Configure how a VFX version is recognised in a name.
Find original recordings
Add recording folders in Rushes. In Assembly, choose the source pools under Source Recordings and select Update Sources. Load an edit, or send new-audio ranges from Conform, then choose Assemble EDL.
Source pools can include Rushes recordings, imported AAF audio and PTX sources. After changing the pools, run Update Sources again. Include all recordings needed to cover the edit.
Inspect and audition the candidates. Selecting one previews it; Use Selected Source Recording assigns it to the event.
Why and Check / Next explain the identity, timing and audio evidence. Names, scene and take metadata, and source timecode help identify recordings. Shared timecode alone is insufficient: check the recording and the full excerpt.
EDL & Matches shows candidates and the evidence for a choice.
Choose the recording pools used by Assembly.
Rushes displays recordings, metadata and source details.
Check timing by listening
Choose Align to Guide to check the timing of a known recording, Find By Audio to search prepared sources, or Forensic Find By Audio for a deeper search when the guide is poor or the recording is uncertain.
Choose Selected, Unmatched or All events, then Run. You can process a few events, review the results and continue.
Verified means the automatic audio checks passed. With Use verified matches automatically enabled, Run assigns a qualifying top result and its timing. With it disabled, audition the candidate and choose Use Audio Match to assign it. Neither action sends audio to Pro Tools.
Guide, Match and Difference share a playhead. Use Loop and Match levels while listening; the source audio remains unchanged.
Set the guide start and channel on the edit timeline before comparing. Source start is a position within the recording file; its BWF timecode, guide placement and output destination are separate values. You can type or drag Source start and audition the alignment.
Compare the guide and candidate recording before applying a match.
Set a file-relative source position and audition the alignment.
Choose microphones
Keep related mono and poly WAV recordings together. Channel Setup provides Automatic, Fixed tracks and Do Not Output choices for microphone routing. A Virtual PolyWAV presents compatible files as a validated set while retaining the original WAVs.
Check the channel layout and incomplete sets before delivery. Multitrack expansion can also reconstruct guide edits across corresponding source WAVs for studio, music or live recordings.
Channel Setup controls microphone groups and output layout.
Review an AAF
An AAF can contain linked audio, embedded audio or both. Use Locate Source Audio in Source Media to find linked files, or Extract Embedded Audio to read audio held inside the AAF.
AAF Assembly can run independently of Conform. For each occurrence, choose Production, AAF or Skip. This lets you use original production recordings where available and keep useful editorial music or effects from the AAF.
Review the candidates and source choice before output. Paired AAFs show new audio alongside its context. Retained editorial audio provides source material and timing, but does not recreate every effect from the editing system.
Review the source choice for each new AAF occurrence.
Inspect the available recordings before choosing a source.
Locate linked audio or extract embedded audio when loading an AAF.
Work from a Pro Tools selection
Quick Spot matches eligible clips selected on one mono Pro Tools track. Choose Timecode, Audio or Alternate Takes, either within Assembly or from the floating palette.
Use it for selected clips without loading a complete Assembly edit or making a guide bounce. Timecode matching needs reliable original timing. Audio matching needs prepared Rushes analysis and readable recordings.
Sample-rate conversion preserves real-time positioning. Unsupported or ambiguous selections are rejected. Check the prepared result before output; raw-source matching does not render plug-ins, fades, routing or Elastic Audio.
Quick Spot offers Timecode, Audio and Alternate Takes controls.
The floating palette keeps Quick Spot controls close at hand.
Compare other takes
Prepare up to 12 ranked alternatives for each event, retaining the microphone layout and timeline coverage. Preview the ranks and channels, audition the performances, then export a PTX or spot the alternatives into Pro Tools.
Transcript evidence can help rank candidates, but a transcription model is optional. If there are fewer suitable candidates, later ranks remain empty. The primary Assembly match stays unchanged.
Each event is ranked separately. The first alternative at one edit point may be a different take from the first alternative at another.
Prepare Alternate Takes shows its options before an output plan is made.
Find a spoken line
Assistant searches local transcripts as you type. Choose Any word, All words, Exact phrase or Fuzzy match. You can search and audition without a running Pro Tools session.
Results identify the recording and physical channel, with timed speech and surrounding dialogue. Select words or drag across the waveform to choose an excerpt, add handles and listen.
Export the excerpt as PTX or spot it into Pro Tools independently of Assembly. The selected In point is placed at the destination, with handles before and after the excerpt.
Choose a local transcription model for your Mac. Whisper supports Intel and older supported Macs. Parakeet requires Apple Silicon and macOS 14 or later.
Search local speech and select an exact excerpt in Assistant.

Check and deliver
Assembly output
Set the destination, output sample rate, scope, channels and enabled tracks. Choose Check Assembly Output, then inspect the tracks, source ranges and warnings before Export Assembly PTX or Send Assembly to Pro Tools.
Audio PTX references the source media, so keep the linked WAVs available for the receiving editor. Sample-rate conversion preserves real-time positions and leaves the original recordings unchanged.
Clip-Group PTX, scene references and unmatched labels provide timing and reference outputs. They do not supply missing production audio. Check the export report for skipped items and their reasons.
Check the proposed output tracks and source ranges before delivery.
Conform delivery
Work from a saved session and backup. Conform copies the reviewed edit, including unchanged KEEP regions, to a separate destination. Check that range across the selected tracks, automation and markers before applying the plan.
Source and destination overlap is blocked under both PTSL and AppleScript, with no Proceed Anyway override. Use Set New Offset to choose an empty destination, or Keep New Timecode by moving the old source range. Prepare and recheck the delivery plan after changing placement.
The original edit remains in place. Project Undo does not reverse commands already sent to Pro Tools. Listen against picture after delivery.
Choose delivery tracks and marker options for the conform.
Return to a project
Save the project to retain your settings, matching choices, comparison ranges and notes. Recordings and guide media remain separate files referenced by the project.
If media has moved, open Media > Check/Relink Project Media. Use Check Again, Find Missing in Folder or Choose Replacement. PT EDL checks format and timing; choose explicitly when more than one replacement is possible.
After relinking, save and check a known event and recording. Rebuild affected results if the source files have changed. Recent Projects & Recovery can restore local work; keep separate backups of the project and its media.
Check and relink project media when files have moved.
Save a comparison range and notes to return to later.
Example: updating an edit after a recut
- Load old and new material, check offsets and calculate the conform plan.
- Review the changes against picture, then copy the existing edit to a separate destination.
- For any new-audio ranges, choose sources in Assembly, inspect the candidates and audition the matches.
- Check Assembly output, then send it to Pro Tools or export a PTX and supply its linked media.
Quick Actions (Command-K) finds commands by name. Assembly can also be used on its own, without these conform steps.
Quick Actions finds commands and workspaces by name.
