Tips for good results

Before you hit create.

  • Use footage you own or have permission to use.
  • Check the first second of each clip: it’s the hook.

Good to know

Questions, answered.

Which videos can I use?

Videos you own or have permission to use: your uploads or a YouTube link to your own content.

Does a high rank mean more views?

No. Ranks describe editorial structure in your footage, not a forecast of views.

Can I post directly to TikTok or YouTube?

Connected publishing is built and awaiting platform approval. Today you download or share the MP4 and post from your own account.
