Check your video title, thumbnail frame and the start of the description the way viewers first see them.
The post is empty.

How draft transfer works
SimplePost opens in a new tab. Sign up or log in, connect a social account, then explicitly import, review and schedule. Keep the same browser and device; saved text expires after 24 hours. Copy your text if you need to switch devices.
Only text and threads transfer; upload media again. DEV versions are excluded. Transfers allow up to 25 posts per version and 200,000 total text units. The trial allows 20 posts per thread. An existing composer draft asks for confirmation before replacement.
How to preview a YouTube post
Viewers decide from the title and thumbnail. The preview shows the player frame, a title clamped to two lines as YouTube does, your channel, and the start of the description, so you can see whether the key words survive the cut-off.
Add the video
Upload the video or a still frame to use as the thumbnail area.
Write the title and description
The first line of your text becomes the title in the preview; keep titles under 100 characters.
Check and download
Read the two-line title and description start, then save a PNG.

YouTube post preview FAQ
How long can a YouTube title be?
100 characters. SimplePost also limits descriptions to 5,000 bytes and rejects < and > in both, as YouTube does.
Can I preview YouTube Shorts?
You can preview a vertical video. YouTube decides whether an upload appears as a Short; SimplePost has no separate Shorts setting.
Can I schedule the upload after previewing?
Yes. Connect your channel in SimplePost, upload the video (up to 500 MB through MCP, the API or the CLI, 50 MB in the web app) and schedule it.
Does SimplePost upload or store my draft?
The tool does not upload drafts. Text is saved locally in this browser for 24 hours; clear it with Clear saved text. Profile details and media are not saved and must be added again.
