What Megaphone is
Megaphone turns a creator's long videos into short clips, adds captions and vertical framing, and schedules or posts them to the creator's own YouTube, TikTok, Instagram and Facebook accounts.
Why it connects your accounts
Megaphone connects to your social accounts only to post on your behalf, and only to the accounts you choose to connect, with the settings you choose for each post. Nothing is published until you choose to post or schedule it, and you can disconnect an account at any time.
A run can hold a finished transcript and a stuck render at the same moment. Merging that into one bar would be a lie, so we don't — only the stage that failed reports a failure, with the code and the fix.
The keep and reject controls from clip review, on sample cards. A rejection needs a reason and stays in place with that reason on the card — what you turned down is half the signal about what you want.
Move the frame, hold the subject, trim the ends against real frames rather than guessing at seconds. Captions come from the transcript, so fixing a word is a text edit — not a re-render and a prayer.
Burned in by the renderer, not the browser
You pick the clips. Not the model.
Most of it is upload and transcription; detection and render are quick by comparison. You don't have to sit and watch — every stage keeps its own state, so you can come back and see exactly where the run got to.
To post your clips on your behalf, and for nothing else. It posts only to the accounts you choose to connect, only after you choose to post or schedule a clip, and with the settings you pick for that post. You can disconnect an account at any time.
No. A clip has to be kept by you, then rendered, then scheduled. Three of those are your decision, and a rejected candidate stays in the gallery as a record rather than quietly disappearing.
Both are yours. Captions are generated from the transcript and editable as text; the crop, the subject position and the in and out points are all adjustable before anything renders.
It stays in the gallery at its original rank, with the reason you picked. A rejection is half the signal about what you actually want, so it stays visible.
YouTube, TikTok, Instagram and Facebook — the accounts you connect to your workspace. Connect once and the account becomes a target you can choose per clip when you schedule it.
Only the stage that actually failed reports a failure — the ones after it read blocked. You get the sanitized failure code, a sentence about the cause, and a retry for that stage alone rather than the whole run.
Ready when you are
One video is enough to see it work. If the moments aren't in there, you've lost an afternoon of uploading and nothing else.
