How it works
The whole path is one confirmed post from your device to your TikTok account.
Sign in with TikTok
Choose Continue with TikTok. PublishVid asks only for user.info.basic, to show your name, username, and photo, and video.publish, to post the video you confirm.
Choose a video
Pick an MP4 or MOV on your device. You see a preview here. The length is checked against the limit TikTok reports for your account. The file is not uploaded yet.
Set the post
Write a caption. Choose who can view the video from the list TikTok returns. There is no default. Comments, Duet, and Stitch start off, and stay off when your account does not allow them.
Say if it promotes a brand
Commercial disclosure starts off. If you turn it on, you say whether the video promotes you, a third party, or both. You also confirm TikTok's music terms. The declaration sits above the post button.
Confirm, then send
After you confirm, your browser sends the video in parts. This server forwards each part to TikTok and does not keep the file. You can follow the processing status here. TikTok may take a few minutes to show the video on your profile.
