Should I timestamp before sending to a sync library?

Yes. Timestamp the exact master and paperwork you deliver, then send.

Does the library's ingest date count?

It shows when that library received the file. It does not date what you had before you sent it.

What about a pitch playlist link?

Timestamp the audio files behind the link, not only a screenshot of the playlist.

Before you pitch a track for sync, timestamp the exact files in the pitch. TimeBinder^® makes a fingerprint in your browser. The files stay on your device. You get a checkable Proof of Time Certificate that shows each exact file existed no later than a recorded time. It does not show who wrote the song, who owns the publishing, or that a supervisor must clear it. Free to start. For cue deliveries after you are on a job, see music cue records for composers.

The routine: timestamp before you send the pitch

Assemble the pitch pack: master, instrumental or TV mix, lyric sheet, and one-sheet or metadata PDF.
Optional. Confirm hashes with the free SHA-256 hash checker.
Timestamp the pack in TimeBinder (up to 10 files, or one zip). Your first Pooled TimeBind is free, with no credit card required.
Save the Proof of Time Certificate with the pack.
Then send to the supervisor, library or agency.
If they ask for a shorter edit or a new mix, timestamp that version before you send it.

What supervisors usually receive

A clean master and often an instrumental.
Lyrics and writer credits.
A short one-sheet: title, length, mood, links.
Sometimes stems for editing.

Date the files you actually attach, not a later re-export. See protect your music before sending and how to timestamp a file.

Writers, publishers and splits

If more than one writer is on the song, fill a split sheet before the pitch and timestamp that PDF with the audio. Clearances later turn on who owns what. A timestamp dates the files; the split records the shares.

What a TimeBind shows, and what it doesn’t

A TimeBind shows that this exact file existed no later than the recorded time. It does not show authorship, ownership or copyright, and it does not clear a sync licence. Keep your publishing paperwork and any library agreement. This is general information, not legal advice.

Your file’s fingerprint, anchored to a global network secured by real electricity and cryptography.

Editing a file—including with AI—changes its fingerprint, not its existing network record.

How this works

Your file’s SHA-256 fingerprint, a short code worked out from its exact contents, is made in your browser, and the file itself stays on your device. A cryptographic commitment to that fingerprint, which may be combined with others, is then anchored in a block on the Bitcoin blockchain. Bitcoin is secured by proof of work: computers around the world spend real electricity to add each block, and changing an earlier block would mean redoing that work faster than the rest of the network. Until that block is confirmed, your proof is pending. Once the Bitcoin anchoring is confirmed, you can verify the proof against that recorded commitment. The confirmed record can then be checked; Pooled TimeBinds are checked through TimeBinder, while ASAP TimeBinds can also be checked independently. If you check the file later and its fingerprint still matches, that shows the file existed no later than the recorded time. The record doesn’t show who made the file, whether AI was used, or that its contents are true.
