One vertical MP4 or MOV, up to 10 minutes of raw footage, filmed portrait the way you already shoot for the feeds. 30 seconds to 5 minutes is recommended for the best results, but shorter and longer videos work too. Talking is the point — the engine edits around speech, so footage where you are telling, explaining, or reacting to something works best.

One vertical short, never longer than 60 seconds, at 1080×1920 — cut, paced, mixed and checked, ready to post to TikTok, Reels, or Shorts. A few minutes of footage usually makes a 40–60 second short; a short upload naturally makes a shorter one.

There is no timeline here. Download and post, or re-run with different footage. That is the deal that keeps it one click: nothing is handed over unfinished, so there is nothing to fix.

Not in the beta. Captions are on the roadmap; today the engine focuses on the cut, the pacing, the mix, and the final checks.

The beta is built and tested English-first. Other languages may produce a result, but we only stand behind English footage for now.

Every export runs through six final checks — sound, dialogue balance, framing, cuts, story, and duration. If it fails, you get a clear reason and your minutes back, not a bad video in your drafts.

Before any editing starts we check the file itself: a supported format (MP4/MOV), a readable video stream, an audio track, and a duration no longer than 10 minutes. A rejected upload costs nothing, and the reason is always shown in plain language.

It is stored privately under your account — other users cannot open it — and auto-deleted after the 14-day default retention window. You can also delete a job’s media yourself. ViralEngine does not use your media to train AI models. OpenAI and other processors we use to run the service may process data as needed to edit, store, or bill.

You keep ownership of the footage you upload and of the finished short, subject to any third-party material already in your source. ViralEngine does not claim ownership. You are responsible for having permission for people, music, and other copyrighted material in the upload, and for what you publish.

Pricing is by the minute of footage you upload, rounded up to the whole minute. The free trial includes 10 minutes with no card; the monthly plan includes 60 minutes a month. Purchased top-up minutes do not expire unless we later change that and say so. Prices shown now are beta prices and may change with notice. A qualifying failed edit returns its minutes to your balance. Paid purchases can be refunded within 14 days through the contact page.
