Can AI replace CineSend?

01What it costs

Checked Aug 12, 2026 · source: cinesend.com.

Hidden costs: Files Teams charges $0.50/GB for Aspera sends; OTT charges $0.01 per streaming minute above the included allowance; CineSend Request charges $0.50/GB downloaded; taxes can be added.

02Could AI build it for you?

The core job: The honest floor: expiring private screener links with a visible per-viewer burn-in, view limits, and an access log. Deterrence, not security.

What a working version needs:

• ffmpeg
• object storage plus a CDN
• a VPS for the screener pages
• an email sender for invites
• an accurate understanding of what a visible watermark does and does not stop

The purest no on the list · the deliverable is not software, it is a rights holder's permission.

03What you'd give up

They pay to be allowed to hold the file. A distributor's security requirements are a contract term, not a preference, and the accepted vendor list is short on purpose. When a screener leaks, forensic watermarking turns a catastrophe into a phone call to one person, and that single capability justifies the whole line item. Nobody is paying 797 dollars a month for a download page.

05The build prompt

Paste this into an AI coding tool (such as Claude, ChatGPT, Lovable or Replit) to build your own version. Read the verdict first: this one is hard to get right.

Build me a watermarked private screener site for footage I own: my own film,
a rough cut for producers, a festival submission I control. This is the
deliberately low-stakes floor of CineSend, never a substitute for it when
someone else's unreleased master is involved. Requirements:

- Node + Express + better-sqlite3 on a VPS, media in Cloudflare R2, hls.js for
  playback. Server-rendered pages, no frontend framework.
- I invite viewers by name and email. Each gets a single-use /s/<random-id> link tied
  to that address, with an expiry date and a max view count I set per invite.
- ffmpeg burns the viewer's name, email, and the date into the picture as a semi
  transparent overlay, one encode per viewer, cached in R2 and deleted on expiry. It
  is visible and it is meant to be, deterrence is the entire mechanism.
- Every play logs timestamp, IP, user agent, and how far they watched, shown on an
  /admin page behind basic auth. I can revoke any link instantly.
- Downloads are off, right click is off, and the manifest URL is signed and short
  lived. State plainly in the UI that none of this stops a screen recording.
- SQLite holds invites and the access log, R2 keys and the SMTP credentials come from
  .env. No accounts for viewers, no telemetry, no third party analytics.
- Out of scope: DRM, forensic watermarking, and TV apps. Do not claim to implement
  any of them and do not build a fake watermark that only sounds forensic.
- README: R2 and signed URL setup, per-viewer encode cost and time, and one blunt
  paragraph saying this is deterrence only and must never be used for a title under
  someone else's security requirements.

06Open-source starting points

• Nextcloud: Self-hosted file sharing with password-protected, expiring share links and access logs. Genuinely solves the delivery half, and stops exactly where the licensed half starts.
• Shaka Packager: Open-source packaging with Common Encryption for Widevine and other DRM systems. Shows the wall clearly: you can encrypt the stream, but the license server and the device keys are not yours to issue.
