Production companies and studios
Many cameras, shifts, several days, a big crew. One way of handling footage across every project: the same folders, passport, reports and project for the edit.
A new standard for handling footage —
on set and in the edit
Shot. Copied.
Synced.
Your editor gets ready footage — and starts cutting right away
MultiSyncer Studio is one app from memory card to edit. While you shoot, it copies cards with verification, sorts footage by camera, makes proxies and dailies, writes the day report and syncs everything by sound, timecode or slate. What comes out is a ready project for your editing app.

Why it's easier
It used to take several apps.
Now it takes one
| Usually | MultiSyncer Studio | |
|---|---|---|
| Card copying | A separate DIT app | Copies to 1–3 drives verified with xxHash64 and ASC MHL |
| Proxies and dailies | Rendered separately, often overnight | In the same pass, right after copying |
| Producer report | A spreadsheet by hand or yet another app | Day report in HTML, PDF and CSV with thumbnails |
| Sync | A plug-in, or clip by clip by waveform | The whole project in one click: sound, timecode, slate |
| Project prep | Import, sort and rename in the editing app | A ready sequence, tracks named with their angle: “A · wide” |
| Long takes | Sound drifts towards the end | Clock drift correction |

One day on set
From the first card to the edit
-
Morning
The first card is copied
The card is copied to several drives at once and checked against checksums. The app recognises the camera by its files and puts the footage in its folder.
-
Day
Everything on the day panel
A card per device, hours recorded, a red mark on cards that aren't safe to format yet. Progress on your phone and in Telegram.
-
Evening
Report and dailies
The shoot-day report with thumbnails — in HTML, PDF and CSV. The director and producer watch the dailies on their phones the same evening.
-
Edit
The project is ready
Footage is synced and laid out on tracks named from the passport, proxies sit next to it. The editor opens the sequence and starts cutting.
Copying on set
Cards are copied all day — into one project
Reliable copies and a day panel
Every card is copied to one to three drives and checked against checksums. The day panel shows what's already copied, what's copying now and which cards aren't safe to format yet. The app itself never formats cards.
- Checksums xxHash64, MD5 and SHA-1; a list of files with their checksums to verify copies, in ASC MHL v2 and MHL 1.1
- Re-reads and re-copies on a mismatch; no half-read files left behind
- A drive disconnects — the app waits for it or carries on without it
- An interrupted copy resumes where it stopped
- Progress per file and time left; a progress page for your phone and Telegram messages
- Take marks while copying: scene, take, “good take”, a note

Proxies and dailies — in the same pass
Right after the copies are checked, the app makes proxies for editing and light viewing copies — dailies. The editor gets proxies next to the originals; the director and producer watch the day's footage on a phone or in a browser.
- ProRes 422 Proxy, DNxHR LB, H.264 and HEVC; several formats in one pass
- The camera LUT from the passport is baked into the picture
- Burn-ins: timecode, camera and angle, clip name, scene and take; a text or logo watermark
- Proxies and dailies to a separate drive, reports to the folder you choose

Project passport
Every camera and recorder gets a letter, an angle, an operator, a lens, a LUT and a note for the editor. The app recognises a card by its files, sorts the footage into device folders, and the names carry through to the report and the tracks in your editing app.
- The editor sees “A · wide”, not “V1” and “C0012.MP4”
- The operator's note goes into the report and along with the footage
- The day's crew is in the report

Shoot-day report
In the evening the producer gets the report: a summary, what was done in the day, a section per device with thumbnails and the details of every file. The report can be emailed straight away. Separate reports go to the colorist and the editor.
- HTML, PDF and CSV; your logo in the header
- Timecode, format, codec profile, bit depth, colour, sound, checksum and copies of every file
- A sound report from the recorder's iXML

Sync
By sound, by timecode, by slate
The whole project — in one click
Each clip's sound is compared with the others and the offset is measured to the sample. If there's timecode, the app uses it; if you shot with a slate, it finds the clap. Cameras, recorders and phones fall into place in one pass.
- Six methods: auto (sound + clock), by sound, by timecode and LTC, by slate, by recording time, by file order
- Sound from every camera channel and track; out-of-phase channels don't cancel out
- Clips are found by sound even if the camera clock was changed during the day
- A shoot over several days or in shifts — one project, shifts in order
- Manual edits: nudge by a frame, pin, “Sync with…”; A/B listening

Clock drift correction
The clocks in a camera and a recorder run at slightly different speeds. On a short clip you can't tell; on a long interview the sound is a few frames behind by the end. MultiSyncer measures each device's speed and resamples the sound to the camera's speed into new WAVs next to the export.
- On a real shoot a 24–81 ppm mismatch became 2–4 ppm
- A long clip's start is taken from the drift line, not the first match
- Source files are untouched — new ones are created
Export
A ready sequence for your editing app
Each device is on its own track named from the passport, the sound is in sync with the cameras. The editor opens the project and gets to work.
- Premiere Pro, DaVinci Resolve, Final Cut Pro, Avid Media Composer (AAF) and any app via EDL
- Flexible export settings: frame rate, sequence frame size, sound, track names and gaps
- Templates: interview, course, event, drama, rough cut, Shorts / Reels
- Gaps where no camera is rolling are shortened
- Takes of one line stacked; a separate sequence per take
- Take marks (good / bad, tags, a note) go to the editing app as markers, keywords and ALE

Who it's for
For production companies and studios —
and for those who shoot on their own
Crews on set
The DIT, data wrangler and assistant copy, mark takes and put out the report on set, and the edit gets footage that's ready to work with.
Interviews, podcasts, courses
Two cameras and a lav? Copy the cards, press “Sync” — and minutes later open a ready sequence. No slate, no lining up by hand.
What everyone gets
Editor
Opens a ready sequence: cameras on tracks with clear names, sound in sync, proxies already there. The edit starts right away.
DIT and data wrangler
Work you can see: every file with its progress and check, a day panel, clear which cards are safe to format. The report writes itself.
Producer
A day report with thumbnails: what was shot, how much, which drives hold the copies. Fewer post-production hours in the budget.
Director
Dailies on the phone the same evening, good takes marked, two angles to compare side by side.
Camera operator
The lens, LUT and note from the camera's passport reach the edit and the colorist. Footage is viewed with the LUT straight away.
Sound recordist
Scenes, takes and track names come from the recorder's iXML. Sound falls under the cameras; clipping and silence are marked.
Colorist
A separate colorist report: cameras, profiles, LUTs and every file's parameters.
Creator and podcaster
Several cameras and a recorder sync by sound in minutes — even without timecode or a slate.
Formats
More than 30 video and audio formats
Cinema cameras and mirrorless, RAW formats, phones, action and 360° cameras, multitrack recorders and wireless lavs. The app recognises a device by its files.
LTC and timecode
Timecode recorded as sound on a track is read automatically. Devices on one generator share one clock.
Scenes and takes
Scene, take, the “circled take” mark and track names come from the recorder's iXML and the camera's tags.
Short phone clips
Clips a few seconds long are found by sound near their own time.
Sound check
Clipping, silence, dead channels and clicks — marks on the clips and markers in your editing app.
Import from your editor
Already started a project? Open XML, FCPXML, AAF or EDL — MultiSyncer syncs the clips and gives the sequence back.
Projects and batches
Autosave and recovery after a crash; several shoot days are processed at once.
Your sources are safe
The app only reads media and never formats cards. Everything new — copies, proxies, sequences, corrected sound, reports — is written to separate files.
Your footage stays with you
Analysis runs on your computer and works offline. Files go only where you send them yourself — to your own cloud folder, for example.
Tested on real shoots
Every version is run on real interviews, courses, events and commercials and checked against sync done by hand by an editor.
“In over twenty years of video production we've seen a lot — and more than once we've run into a mess when footage was being copied. Mixed-up cards, lost files, hours spent rebuilding a project and overnight proxy renders. We know that pain well, and we know how much time and money it costs the whole crew. Now one app takes care of all of it: the footage is copied reliably, sorted by camera and synced, and the editor gets a ready project the same day.”

FAQ
Frequently asked questions
Can I try it for free?
Yes. Download the app — for 14 days every feature works with no key and no sign-up.
What happens after the trial?
You can open and look at a project, and sync, export and card copying work again once you enter a key. Everything you've already made — card copies, proxies, reports, sequences, corrected sound — stays yours and keeps opening.
How do I buy a licence?
Pick a plan under Pricing and pay by card, SBP or SberPay — YooKassa takes the payment. The key appears on the page and arrives by email; you enter it in the app under “? → Licence”. Terms are in the licence agreement.
How many computers does one key cover?
A key is issued for a computer's code. One key covers 2 computers; you can work on one of them at a time. Add the second computer on the A second computer page: paste your key and the second computer's code to get a key for both. If a computer breaks or is sold, it can be replaced with another one, once in 30 days.
How does the app update?
By itself: at launch and once a day it checks for a new version and offers to install it. No need to download the installer again.
Does the app make proxies and dailies?
Yes, in the same pass as the copying: proxies for editing (ProRes 422 Proxy, DNxHR LB, H.264, HEVC) and viewing copies with the camera LUT, timecode, camera name, scene and take burned in, and a watermark. You can put them on a separate drive.
Where does my data go?
Your footage goes nowhere: video, sound, file and folder names stay on your computer — everything is computed there. Error logs are sent only if you turn sending on in the settings (it's off by default), and file names and paths in them are replaced by codes. Details are in the privacy policy.
Do I need timecode or a slate?
No. The app finds shared sounds across all recordings. If there is timecode (including LTC recorded on an audio track) or a slate, they are used too; you can also sync by slate or by timecode on their own.
Does the app format cards?
No, never. It only shows which cards are safe to format: that takes two verified copies on different drives. A single copy, or a copy in a cloud folder, doesn't count. Cards that aren't safe to format yet are marked red.
Does card copying replace dedicated DIT apps?
For most shoots, yes: copying to several drives at once, xxHash64/MD5/SHA-1 verification, ASC MHL, retries on errors, resuming an interrupted copy, checking copies against MHL, proxies and dailies, and a day report in HTML, PDF and CSV.
What if a clip shares no sound with the others?
It's placed by timecode or by its camera's clock, matched to that camera's other clips. Any clip's position can be adjusted by hand: nudge by a frame, pin, “Sync with…”.
How accurate is the sync?
The offset by sound is measured to the sample. Every version is tested on real shoots: clip positions are checked against sync done by hand by an editor. For long takes there's clock drift correction.
The shoot ran over several days. Is that one project?
Yes. Days and shifts — even months apart — are synced as a whole: they line up in order with no overlaps, and long breaks become a minute on the timeline.
Which editing apps does it work with?
Adobe Premiere Pro and Vegas (XML), DaVinci Resolve (FCPXML 1.9), Final Cut Pro (FCPXML 1.10 with a multicam clip), Avid Media Composer, EDIUS and Pro Tools (AAF, ALE), and any other app via EDL. You choose the sequence frame rate and frame size when exporting.
Which formats are supported?
More than 30 video and audio formats: MOV, MP4, MXF, MTS, MKV, AVI, camera RAW formats, 360° camera files, action cameras' low-res copies; sound in WAV/BWF, RF64, AIFF, FLAC, MP3, AAC and more. Final Cut Pro can't open Blackmagic RAW, so those files are left out of its export.
Does the app change my files?
Never. Source media is only read. Copies, proxies, sequences, corrected sound and reports are created as separate files.
Do I need the internet?
No, everything is computed on your machine. The internet is used for updates and for what you turn on yourself: Telegram messages, a copy to a cloud folder, anonymous error logs (off by default).
Which computers does it run on?
macOS 12 or later — on Macs with Apple chips (M1–M4) and on Intel Macs. Windows 10 and 11 (64-bit). No need to install Python, ffmpeg or anything else — it's all inside the installer.
macOS says it can't verify the developer. What do I do?
Double-click the app and click “Done”. Then open System Settings → Privacy & Security, scroll down and click “Open Anyway”. You only need to do this once; an illustrated guide comes with the installer.
Windows says “Windows protected your PC”. What do I do?
That's the SmartScreen filter: it greets new apps it doesn't recognise yet this way. Click “More info”, then “Run anyway”. Usually you only need to do this on the first launch.
Can I sync a project I've already started in my editor?
Yes. Export it to XML, FCPXML, AAF or EDL, open it in MultiSyncer — and get a synced sequence back.
Where do I write if something goes wrong?
Right from the app: “? → Report a problem or idea” — the email goes along with the sync report. Or write to support.
