Create a reel

Publish one vertical video to Instagram, Facebook, TikTok, YouTube Shorts, Telegram and Discord.

A reel is one short video that you publish to several channels at once. With the Reel post type you can schedule the same video as an Instagram Reel, a Facebook Reel, a TikTok video, a YouTube Short, a Telegram video and a Discord video.

Where reels publish

ChannelPublishes asMaximum lengthMaximum file size
InstagramReel15 minutes300 MB
FacebookReel240 minutes1 GB
TikTokVideo10 minutes, or less if your TikTok account has a lower limit1 GB
YouTubeShort3 minutes1 GB
TelegramVideoNo limit50 MB
DiscordVideo messageNo limit1 GB

The 1 GB maximum on TikTok, YouTube and Discord is the OmniSocials upload limit. On Discord, a video over 20 MB goes into the message as a link, and Discord plays it from there. TikTok sets the maximum video length per account (3, 5 or 10 minutes), and the editor shows your account's limit when you open the TikTok version of the reel.

Create a reel

  1. Click Create Post in the sidebar.
  2. Click the Reel tab at the top left of the editor. Only Instagram, Facebook, TikTok, YouTube, Telegram and Discord stay in the channel bar.
  3. Click Select Reel and pick a video from your Library, or drag a video from your computer onto the frame. A reel holds one video.
  4. Write your caption under Reel Description.
  5. Choose a cover under Thumbnail. See the next section.
  6. Click a channel's icon to adjust that channel's version, for example the Short Title for YouTube.
  7. Click Schedule Reel to pick a date and time, or Post now to publish right away.

When the video is longer than a selected channel allows, the editor shows Video too long with the maximum for that channel. Trim the video or turn that channel off.

Choose a cover

The Thumbnail section appears once you've selected a video.

  • Select from library: click Select Thumbnail and pick an image from your Library. A 9:16 image works best.
  • Select from video: move the slider to the frame you want to use.

Four channels handle covers differently:

  • TikTok doesn't accept a custom cover image. Your TikTok video uses a frame from the video, so choose Select from video to pick that frame.
  • YouTube shows a custom cover on Shorts only on channels where YouTube has turned on custom Shorts thumbnails, starting with Partner Program channels. On other channels the Short shows a frame from the video.
  • Telegram doesn't use the cover. The video goes to your chat without it.
  • Discord doesn't use the cover either. The video goes to your channel without it.

Videos that aren't vertical

Reels play in a 9:16 frame. If your video has another shape, OmniSocials doesn't crop it. Viewers see it with bars above and below (landscape video) or on the sides, and the cover uses the middle of the frame. The editor shows a note when this applies. Add a 9:16 cover image for a clean tile on your profile grid.

Settings per channel

Each channel's reel settings are post options: chips in the bar under the editor, and all of them in the panel that the arrow at the end of the bar opens. See Set post options.
